Athlete Nutrition and Long-Term Health: Staying Strong After 30 Years of Cycling—Sustainable Eating and Chronic Disease Prevention

Starting with a 50-Year-Old Student’s Health Check Report

I’ve been coaching athletes for nearly 15 years, and I’ve seen all kinds of impressive power curves and the excitement of PRs being broken. But what truly keeps me up at night isn’t usually the wattage gains of a given training block — it’s something far more long-term: will this person’s body still be in good shape after 20 years of riding?

A few years ago, a veteran student in his early 50s, who consistently rode 200–300 km a week, came to me with his health check report. He proudly said, “I train this hard, my numbers must be great.” But when we opened it, his body fat was indeed low and his resting heart rate of around 40 bpm was very athletic — yet his fasting blood glucose was elevated, triglycerides were flagged in red, and LDL cholesterol wasn’t ideal either. He was stunned: “I train this much — how is this possible?”

I asked him to write down a week’s worth of his diet. The answer was hiding right there — years of relying on sugary sports drinks, energy gels, convenience store pastries, and bubble tea to fuel his training volume, without ever switching back during the off-season. He used exercise to offset calories, but he never offset the 20–30 years of accumulated stress those dietary habits placed on his metabolism and blood vessels.

That experience was a profound reminder for me, and it’s why I want to write this long-form piece: athletic performance and long-term health are not two things that automatically move forward together on the same track. You can be very good at cycling while slowly pushing yourself toward metabolic syndrome. If sports nutrition only serves “making today’s ride feel great” while ignoring your cardiovascular system, bones, and metabolism a decade down the line, the bill will slowly arrive in your 40s and 50s.

In this article, I want to focus on an area rarely covered in hype-driven training articles: the long-term impact of sports nutrition on chronic disease, and how to build a sustainable way of eating that can carry you through a lifetime.

To be clear upfront: this is educational content discussing general principles. If your blood glucose, lipids, blood pressure, or bone density numbers show red flags, please seek individualized assessment from a physician and dietitian — don’t treat an internet article as a prescription.

Why “Being Active” Doesn’t Equal “Metabolically Healthy”

Exercise Is Powerful, But Not a Blanket Get-Out-of-Jail Card

The benefits of exercise for health are beyond doubt: improved insulin sensitivity, lower blood pressure, higher HDL cholesterol, better mood and sleep. But there’s a common misconception here — exercise cannot “offset” a poor diet without limit.

The logic is actually quite straightforward. A three-hour hilly group ride burns roughly 1,500 to 2,000 kcal, which sounds like a lot. But one full-sugar bubble tea, a pineapple bun, and half a box of energy gels can easily fill that window with calories and refined sugar — and what goes in is “high-glycemic, low-nutrient-density” stuff. The repeated blood sugar spikes and crashes, visceral fat accumulation, and chronic low-grade inflammation over the long term are the real foundation of chronic disease. Exercise can mitigate these, but it’s very hard to wash them all away with training volume alone.

Chronic Disease Is “Accumulated,” Not Something That Happens Overnight

Type 2 diabetes, hypertension, and atherosclerosis are almost all the result of 20–30 years of gradual accumulation. They won’t disappear just because you trained hard this month, and they won’t flare up immediately because you ate poorly this week. Precisely because the feedback is so slow, people tend to let their guard down — “well, I exercise, so it’s fine” becomes a self-soothing get-out-of-jail card.

I often tell my athletes: your riding performance at 40 depends on the training you do in these years; but whether you can still make it up Wuling at 60 depends on what you eat, day after day, from your 20s and 30s through your 40s and 50s.

Athletes Actually Face Two Unique Risks

What’s even more ironic is that the athletic population has two nutritional traps that the general public rarely encounters:

1. The “I’m burning it off, so I can eat anything” mindset, which leads many endurance athletes to consume large amounts of refined sugar and processed foods long-term, unable to quit even in the off-season.
2. The other extreme: chronically insufficient energy intake (especially among riders and runners chasing low body weight and fast climbing). The body stays in a state of low energy availability for extended periods, which actually harms bones, hormones, and the cardiovascular system. In sports medicine, this is called Relative Energy Deficiency in Sport (RED-S / REDs), and its long-term consequences include decreased bone density, stress fractures, hormonal and menstrual dysfunction, immune suppression, and even cardiovascular health impacts (source).

Eating too poorly and eating too little are two sides of the same coin — both will quietly steal your health over the long run.

Another Case: A 26-Year-Old Climber Desperately Cutting Weight

Let me give another example — one completely opposite to the opening story, but one that worries me just as much. A 26-year-old young rider aiming for a good placing in climbing races like Wuling spent nearly the whole year dieting, keeping his weight very low. His power-to-weight ratio was indeed impressive. But when he came to me, his complaints were “I’m following my training plan, yet my results have plateaued, and I keep getting minor colds and sleeping poorly” — and within the past six months, he’d already had one episode of foot pain suspected to be a stress reaction.

The moment I looked at his diet log, I frowned: his long-term energy intake was far below his training expenditure, and his protein was insufficient too. This was textbook low energy availability — the body, in order to survive, downregulates “non-essential” functions like bone building, immunity, and hormones. He thought he was moving toward “faster,” but he was actually heading toward “more injury-prone, harder to improve, and deteriorating bones over the long term.”

The first thing I asked him to do wasn’t more training — it was to restore his daily energy and protein intake, and I referred him to a sports medicine and nutrition team for evaluation. Put these two cases side by side, and you’ll see my point: one ate too poorly, the other ate too little — yet both were racking up chronic health bills for their future selves. Healthy, sustainable eating is the narrow path between these two extremes — the one that lets you go the distance.

Key Mechanisms by Which Sports Nutrition Affects Long-Term Health

This section is a bit more technical, but understanding the “why” is what will make you willing to stick with it long-term. I’ll keep it to ranges and principles — I won’t pretend to have numbers precise to the decimal point.

1. Blood Sugar and Insulin: The Landmine Endurance Athletes Most Often Overlook

Endurance training does improve insulin sensitivity, which is a good thing. But if you also consume large amounts of refined sugar and high-glycemic foods during non-exercise hours year-round, your pancreas is forced to secrete large amounts of insulin over time. Eventually, sensitivity may actually decline, leading toward insulin resistance — the precursor to type 2 diabetes.

Key concept: fast carbohydrates during and right after training are useful fuel and recovery tools; but high-sugar eating while sitting at a desk, binge-watching shows, or during the off-season is purely a metabolic burden. The same sugary drink has a completely different meaning when consumed mid-climb versus on the couch.

As for “how much sugar should you eat,” the World Health Organization recommends keeping free sugars (including added sugars, honey, syrups, fruit juice, etc.) below 10% of total daily calories, and ideally below 5% if possible. However, to be honest, this recommendation is primarily based on evidence around obesity and dental caries; the direct causal link between free sugars and cardiovascular disease is still not entirely consistent in the literature and continues to accumulate (source). So what I tell my athletes is conservative: cut sugary drinks as much as you can, and trim refined sugar outside of training as much as possible — that direction is broadly sound; but don’t obsess over hitting some precise percentage.

2. Blood Lipids and Blood Vessels: Fat “Quality” Matters More Than “Quantity”

Many people used to fear fat, but for endurance athletes, fat is not only a crucial fuel — it’s also intimately tied to hormone synthesis and cell membrane health. The key to long-term health isn’t “whether you eat oil,” but what kind of oil you eat, and whether it’s been overly processed.

The rough direction is: get unsaturated fats mostly from fish, nuts, olive oil, avocado, and whole foods; reduce trans fats (found in many puff pastries, fried foods, and low-quality baked goods) and excessive processed meats. As a general principle for long-term blood lipids and vascular elasticity, this direction holds up well.

3. Inflammation: Chronic Low-Grade Inflammation Is the Common Soil of Chronic Disease

Cardiovascular disease, type 2 diabetes, and certain cancers all share a common foundation—chronic low-grade inflammation. Highly processed foods, excess refined sugar, large amounts of poor-quality oils, prolonged energy deficits, and insufficient sleep all keep the body in a state of chronic inflammation.

Exercise itself has long-term anti-inflammatory effects, but if your diet keeps “adding fuel to the fire,” you’re putting out fires while starting new ones. The dietary strategies of vegetables and fruits, diverse plant foods, omega-3s, and adequate polyphenols (from colorful produce, tea, and spices) all work in the direction of lowering the body’s long-term inflammatory baseline.

Here I want to specifically remind endurance athletes of something easily overlooked: high training volume itself creates oxidative stress and short-term inflammation—this is a normal training stimulus that the body converts into adaptation through recovery. But if you stack insufficient sleep, a highly processed and high-sugar diet, and chronic energy deficiency on top of high training volume, your body slides from the virtuous cycle of “inflammation—repair—get stronger” into a chronic state of “persistent inflammation, incomplete repair.” The key to long-term health is not eliminating inflammation entirely (that’s neither possible nor necessary), but rather giving the body enough recovery materials (sleep, protein, vegetables and fruits, energy) so that every bout of training-induced inflammation can be properly resolved.

4. Bone Health: The Hidden Cost of Eating Too Little

Many climber-type cyclists and runners desperately cut weight, and chronic under-eating pushes them into the RED-S risk zone. When the body is energy-deficient, it downregulates many “non-essential” functions, including bone formation. Over time, bone density declines, stress fracture risk rises, and female athletes may also experience menstrual dysfunction—these are real, tangible harms to long-term bone health (reference).

Being light should never come at the cost of your bones and hormones. This is something I always put the brakes on and remind every athlete who wants to “get a little lighter to climb faster.”

5. Gut and Fiber: The Most Underrated Piece of Long-Term Health

Many endurance athletes have monotonous diets—white rice, white noodles, energy gels, whey protein—with severely inadequate fiber and plant diversity. Over time, gut microbiome diversity declines, which can affect metabolism, immunity, and even mood. I won’t exaggerate this into “the gut determines everything,” but what’s certain is: consistently getting enough fiber and diverse plants is a positive general principle for metabolic health and satiety. Taiwan actually has a rich selection of vegetables and fruits—sweet potato leaves, amaranth, mushrooms, various gourds, and seasonal fruit—you can boost plant diversity at low cost.

6. Sodium, Potassium, and Blood Pressure: The Hidden Issue in Taiwanese Diets

Sodium content in Taiwanese restaurant food is generally high (noodle soups, braised snacks, processed foods, sauces), while most people don’t get enough potassium (from vegetables and fruits). Sweating during exercise does cause sodium loss, but that doesn’t mean you should eat a high-sodium diet daily—sodium replenishment during training and the principle of low sodium/high potassium in daily life should be viewed as separate scenarios. For long-term blood pressure health, reducing processed foods, not drinking soup down to the bottom, and eating more whole plant foods are all well-supported directions. If you already have hypertension, sodium intake must be individually advised by your physician and dietitian based on your condition—don’t apply a formula on your own.

Dietary Focus Points for Different Chronic Disease Risk Groups

In this section, I’ve organized the most important dietary focus points for three common chronic disease risks into a table. To reiterate: the following are general directions, not prescriptions; anyone with related conditions must seek individualized medical care.

Risk Group	Primary Dietary Focus	Special Notes for Athletes	Signals That Require Medical Attention
Elevated blood sugar / diabetes risk	Reduce refined sugar, choose low-glycemic options, adequate fiber and protein	Fast carbs reserved only for around training sessions	Elevated fasting glucose or HbA1c
Dyslipidemia risk	Improve fat quality, reduce trans fats and processed meats	Don’t eliminate fat entirely out of fear—quality matters	Persistently elevated LDL cholesterol
Elevated blood pressure risk	Reduce sodium, increase potassium (vegetables/fruits), manage weight	Training sodium replenishment and daily low sodium should be separated	Repeatedly elevated blood pressure readings

The purpose of this table is so that when a number on your health check report comes back red, you have a rough idea of which direction to nudge your diet—then take that direction to your physician and dietitian and turn it into an individualized plan for you.

Supplements: Build the Foundation First—Supplements Are Only Fine-Tuning

Athletes ask about supplements more than anything, but I always leave supplements for last because their importance is far below that of daily diet. Here’s a table organizing the positioning of common supplements, helping you distinguish which are “training tools,” which are “nutritional gap-fillers,” and what to note before use.

Supplement	Primary Role	Significance for Long-Term Health	Reminder Before Use
Whey / protein powder	Fill protein gaps	Supports recovery and maintenance of muscle and bone	It “fills gaps,” not “replaces” whole-food protein at meals
Electrolytes / salt tablets	Sodium replenishment for long, high-intensity sessions	Training-scenario only, not for daily use	Those with high daily sodium intake should actually be cautious
Omega-3	Fills the gap of insufficient good fats in the diet	Aligns with anti-inflammatory and lipid goals	Anyone on anticoagulant medication must consult a physician first
Vitamin D	Bone and immune health	Many in Taiwan are low, especially those with limited sun exposure	Dosage should follow blood test results and medical advice
Caffeine	Training performance aid	Little relevance to long-term health	Those affected by sleep should watch the timing

My position is clear: no supplement in a bottle can rescue a chronically poor daily diet. Supplements are the final 5% of fine-tuning; the first 95% is whole foods and overall dietary structure. And if you have a chronic disease, are on medication, or are pregnant or breastfeeding, you should always consult a physician or pharmacist before using any supplement—this isn’t just a polite phrase; there’s real risk of interactions.

What a Sustainable Week of Eating Looks Like (Example, Not a Prescription)

Athletes often say, “I understand the principles, but what does a week actually look like?” Here’s a rough framework to give you a picture. This is only a structural example—portions and contents should be adjusted to your body weight, training load, and health status.

Day	Training	Dietary Focus
Monday (rest)	None	Return to daily pattern: low-glycemic, adequate protein, plenty of vegetables
Tuesday (intervals)	High intensity	Moderate carbs around training; other meals back to whole foods
Wednesday (easy)	Low intensity	Daily pattern: fill fiber and good fats
Thursday (rest)	None	Daily pattern: watch hydration and vegetables/fruits
Friday (tempo)	Moderate-high intensity	Post-training carb + protein recovery meal
Saturday (long distance)	Long duration	Fast carbs and electrolytes during training; proper recovery after
Sunday (social ride)	Low-moderate	Allow flexibility, but don’t make exceptions all day

You’ll notice that within a week, only two or three training windows actually require “sports fuel mode”; the rest of the time, the body needs a return to daily eating that takes care of long-term health. Getting the ratio between these two modes right is the essence of sustainable eating.

Taiwan-Specific Chapter: Long-Term Nutrition and Hydration in a Hot, Humid Climate

Taiwan’s heat and humidity are variables you cannot ignore when planning nutrition and hydration. During long rides along riverside paths or in the mountains in summer, the sweat and electrolytes lost in a single outing are considerable. If replenishment is inadequate, short-term performance and safety suffer, and repeated dehydration and electrolyte imbalance over time also place a burden on the body.

The principles I give my athletes are simple:

• During long, high-intensity training sessions: Hydration needs to keep pace with losses, and electrolytes should be supplemented when needed. This is where sugary or sodium-containing sports drinks truly belong. The hotter the weather and the longer the session, the more proactively you must plan your fueling—don’t wait until you’re thirsty or cramping to react.
• In daily life: Plain water should be the mainstay, with sodium and potassium coming mostly from whole foods. Eating out in Taiwan is already on the salty side; in daily life you really don’t need sugary electrolyte drinks to top up sodium—that’s just extra sugar.
• Post-race recovery: Recovery matters even more in hot, humid conditions. Carbohydrates plus protein plus adequate fluids and electrolytes allow the body to properly recover from the stress of heat and sweating.

Also, Taiwan’s fruit is abundant and excellent—a great natural fuel source and source of antioxidants. A banana before or after training, or a variety of seasonal fruits during the season, is low-cost and locally relevant, far more practical than relying solely on imported energy products. Making good use of local ingredients means sustainable eating can last, and your wallet won’t give out first.

Practical Approach: Turning Sustainable Eating into a System

Now that the mechanisms are covered, let’s talk about how to do it. I dislike those “30-day strict sugar detox” short-term challenges because they almost inevitably lead to regaining the weight and giving up. The core of sustainable eating isn’t perfection—it’s habits you can maintain at about 80% consistency over the long term.

Principle 1: Distinguish Between “Training Nutrition” and “Daily Nutrition”

This is the most important mindset shift, in my view. Many people mistakenly carry the fueling logic used during exercise (large amounts of fast carbohydrates) into daily life, so they spend all day eating “sports fuel” while not actually exercising.

The table below is a scenario comparison I often give athletes, helping you separate the two modes:

Scenario	Goal	Carbohydrate Strategy	Suitable Food Examples	Common Mistakes
During long, high-intensity training (>90 min)	Fuel, maintain intensity	Fast carbohydrates needed	Sports drinks, energy gels, bananas	No fueling at all, hitting the wall
30–60 minutes post-training	Quick recovery, replenish liver glycogen	Carbs + protein together	Chocolate milk, rice + eggs, sweet potato + chicken	Only carbs, no protein
Regular workdays, off-season	Metabolic health, satiety	Whole foods, low glycemic index	Whole grains, vegetables, legumes/fish/eggs/meat, good fats	Applying sports logic and bingeing on refined sugar
Fat-loss phase	Preserve muscle, slow weight loss	Moderate carbs, adequate protein	Protein + lots of vegetables	Cutting too aggressively into RED-S

You’ll notice energy gels and bubble tea should only live in the first box—they shouldn’t move into the other three.

Principle 2: Use a “Plate Structure” Instead of Obsessively Counting Calories

I don’t ask most adult recreational athletes to weigh and calculate kcal for every meal—that’s too hard to sustain long-term. I prefer a structured plate concept that’s simple and works even when eating out:

• Half the plate: vegetables and fruit (the more colors, the better—polyphenols and fiber in one go)
• One quarter: quality protein (fish, seafood, eggs, soy products, lean meat; endurance athletes have higher protein needs)
• One quarter: quality starches (whole grains, sweet potato, brown rice, pumpkin; increase portions on training days)
• Add a little good fat on top (olive oil, nuts, avocado)

The beauty of this structure: it simultaneously covers recovery (protein + carbs), anti-inflammation (vegetables, fruit, good fats), and long-term metabolic health (low glycemic index, high fiber)—and you don’t have to carry a food scale around.

Principle 3: Protein—What Endurance Athletes Most Often Don’t Eat Enough Of

Many people think only weight training requires protein, but endurance athletes also have higher protein needs for muscle repair, immune function, and bone health. General adults need about 0.8–1.0 g per kilogram of body weight, while endurance athletes with heavy training loads typically fall in the range of about 1.4–1.8 g per kilogram (giving a range, adjusted by individual and training load—no need to pretend it’s precise).

What matters even more is distribution: don’t eat very little all day and then binge on a big chunk of meat at night. Instead, include a serving of protein at each of the three meals so the body has building materials for repair throughout the day.

Here’s a sample daily protein distribution I often give athletes (using a roughly 65 kg rider with moderate-to-high training load as an example; this is only a structural illustration, not an individual prescription):

Meal	Example Protein Source	Notes
Breakfast	Two eggs + unsweetened soy milk	Doable at a Taiwanese breakfast shop
Lunch	A palm-sized portion of fish or chicken breast + brown rice	Can be done at a buffet
Post-training	Chocolate milk or whey protein	Recovery window, carbs + protein
Dinner	Tofu or lean meat + lots of vegetables	Can slightly reduce starches at night

Principle 4: In Taiwan, Treat “Eating Out” as the Main Battlefield, Not the Exception

Taiwanese people eat out at a very high rate. If a dietary approach only works when you cook for yourself, it’s doomed to fail. Sustainable eating must survive at buffets, convenience stores, and noodle shops. A few local techniques I actually teach athletes:

• Buffet restaurants (自助餐) are a hidden ally: load up on vegetables first, pick one non-fried protein, and halve the rice—it easily fits the plate structure.
• Convenience stores can make a decent meal: tea eggs or chicken breast, unsweetened soy milk or milk, sweet potato, salad, unsweetened tea.
• Bubble tea (手搖飲) is one of the biggest hidden sugar sources for Taiwanese people: going from full sugar to half, then less, then gradually to no sugar or reduced frequency is far easier to sustain long-term than quitting all at once.
• Taiwan’s hot, humid climate means heavy sweating during training, so hydration and electrolytes must keep pace, but daily hydration doesn’t require sugary sports drinks—plain water plus the sodium and potassium in whole foods is usually enough; save sugary electrolyte drinks for truly long, high-intensity training sessions.

Common Mistakes and Corrections

These are mistakes I’ve seen repeatedly over the years, almost replaying with every new group of athletes.

Mistake 1: Bringing In-Season Fueling Logic into the Whole Year

Symptoms: Drinking sports drinks and eating energy bars year-round, thinking “I’m an athlete, so I need to fuel with carbs.”
Correction: Clearly separate training scenarios from daily life. Fast carbohydrates are a tool, not a staple. In the off-season and outside training windows, return to whole foods and a low glycemic index diet.

Mistake 2: Desperately Cutting Weight for Climbs and Falling into Energy Deficiency

Symptoms: Weight keeps dropping, fatigue, frequent injuries, irregular menstruation in women, frequent colds, and performance stagnating or declining.
Correction: These are warning signs of RED-S. Immediately bring energy intake back up and seek help from a sports dietitian and physician. Weight loss should be slow and should never come at the cost of bone and hormonal health (reference).

Mistake 3: Concentrating Protein in One Meal and Eating Too Little at Others

Symptoms: Slow recovery, muscle loss, declining immunity.
Correction: Distribute protein evenly across three meals, and don’t forget the carbs + protein recovery meal after training.

Mistake 4: Being Extremely Afraid of Fat—or, Conversely, Binging on Low-Quality Fats

Symptoms: Low hormone levels, poor joint and skin condition; or chronically poor blood lipid profiles.
Correction: The key is fat quality. Focus on polyunsaturated and monounsaturated fats, and avoid trans fats and heavily fried processed foods.

Mistake 5: Obsessing Over Single Supplements While Ignoring Overall Diet

Symptoms: A pile of bottles and jars, but meals are a mess.
Correction: No supplement can rescue a poor daily diet. First build the foundation with whole foods; supplements are only the final fine-tuning. And any supplement, in the presence of chronic disease or medication use, should be discussed with a physician or pharmacist first.

Mistake Six: Only Watching Short-Term Weight and Performance, Ignoring Long-Term Health Markers

Symptoms: Dietary adjustments revolve only around “did I lose weight or get faster this week,” while never looking at long-term markers like blood sugar, blood lipids, blood pressure, or bone density.
Correction: Treat your annual basic health checkup as the dashboard for your dietary strategy. Taiwan’s National Health Insurance and checkup environment are actually very convenient; most adults have access to free or low-cost adult health screenings. Using objective numbers to correct your course is far more reliable than adjusting based on feelings. If you see red flags, don’t panic—bring them to your doctor and dietitian, and use them as the starting point for individualized adjustments.

Actionable Advice for Readers at Different Levels

Everyone starts from a different point, so I’ve split the advice into three reader profiles. Just find the one that fits you.

For Beginners Who Exercise Occasionally

You don’t need to overhaul everything at once. Pick one or two of the easiest changes to start with, maintain them for three months until they become habits, then add the next one:

1. Reduce sugary drinks from full sugar to half sugar or less, and cut the frequency in half.
2. Increase your vegetable portion to half of your plate at every meal.
3. Ensure every meal includes a palm-sized portion of protein.

Just consistently doing these three things long-term will do more for your metabolic health than buying any supplement.

For Those Training Steadily Weekly, Balancing Performance and Health

1. Clearly separate “training nutrition” from “daily nutrition.” Reserve fast-acting carbohydrates for long, high-intensity training sessions only.
2. Aim for protein intake in the range of 1.4–1.8 grams per kilogram of body weight, distributed across your meals.
3. During the off-season, actively return to whole-food, low-glycemic eating. Don’t let race-fueling logic run year-round.
4. Get at least one basic health checkup (blood sugar, blood lipids, blood pressure) per year, and base your dietary adjustments on your own numbers, not on feelings.

For Competitive Readers Chasing Performance and Managing Weight

1. Lose weight slowly. Set a reasonable lower limit and be alert to all warning signs of RED-S (fatigue, frequent injuries, decreased immunity, menstrual irregularities in women).
2. Even during a weight-loss phase, protein and adequate energy availability cannot be sacrificed.
3. Regularly monitor bone health and hormone-related markers, and collaborate with a sports medicine team when necessary.
4. Remember: The ones who consistently stand on the podium are often not the most extreme dieters, but those who take care of their bodies well enough to keep training for many years.

Frequently Asked Questions (FAQ)

Q: Should I really consume sugar during training? Doesn’t that contradict eating less sugar?
A: There’s no contradiction. During prolonged, high-intensity exercise, fast-acting carbohydrates are essential fuel—your body needs them at that moment. The contradiction lies in bringing that logic into your sedentary daily life. Sugar is fuel at the right time, and a burden at the wrong time.

Q: My blood sugar and blood pressure are already in the red zone. Should I just follow this article to adjust on my own?
A: No. If you have chronic conditions or red-flag numbers, you must first seek individualized assessment from a doctor and dietitian. This article discusses general principles and cannot replace a diagnosis and prescription tailored to your specific condition. Especially if you are taking medication, dietary changes may require simultaneous medication adjustments, which only a medical team can determine.

Q: Eating out is so common in Taiwan. Is this really feasible?
A: Yes, it is, and it must be. A dietary approach that can truly be maintained long-term is one that can survive in buffet restaurants, convenience stores, and noodle shops. Treat eating out as your main battlefield to design around, not as an excuse for exceptions.

Q: Do I need to take a lot of supplements?
A: Most people don’t. Building a solid foundation with whole foods is far more effective than stacking up supplements. Supplements are the final fine-tuning, and you must first confirm they don’t conflict with your health conditions or medications.

Q: I’m already very lean and climb well. Do I still need to worry about undereating?
A: The leaner you are, the more careful you need to be. Being light with a good power-to-weight ratio doesn’t mean your energy intake is adequate; many RED-S cases outwardly appear to be “lean, high-performing athletes.” The real indicators are your body’s signals: sleep, immunity, hormones, bone health, and long-term performance trends. If these are deteriorating, it means you’re not getting enough energy, even if you’re lean.

Q: So, should I weigh myself and count calories or not?
A: The tools themselves aren’t wrong; being controlled by them is. For most general adult athletes, I recommend managing with “plate structure + body signals (energy, recovery, performance, checkup numbers)” rather than obsessing over the scale and calorie apps daily. If you have a tendency toward disordered eating, excessive tracking can actually be harmful, and that’s when you should seek professional help.

Q: If I occasionally overeat or have a full-sugar drink, is all my progress lost?
A: Not at all. Sustainable eating is about the long-term 80%, not perfection at every meal. An occasional social dinner or a treat drink fits perfectly fine within the larger long-term structure. What harms you is never the occasional exception, but the daily routine. Don’t let guilt over one slip-up make you abandon the whole system—that would be the real loss.

Conclusion: Do You Want Your Sixty-Year-Old Self to Still Be Able to Ride?

Let’s return to that fifty-year-old student from the beginning. Over about six months, he gradually replaced his high-sugar diet outside of training with whole foods, cut his sugary drinks from full sugar to sugar-free, added protein to all three meals, and stopped relying on energy gels during the off-season. He didn’t do any extreme sugar-detox challenge; he just steadily swapped out eighty percent of his habits. A year later, at his follow-up checkup, his blood sugar and blood lipids had moved in the right direction, and he had more energy.

What I want to leave you with isn’t a perfect meal plan you’ll abandon in three days, but a long-term perspective:

The true purpose of sports nutrition isn’t just to make you fast this weekend, but to ensure that at sixty or seventy, you can still wheel your bike out and climb your favorite hill. Chronic diseases are built up over decades, and sustainable eating is the health capital you deposit for your future self every single day.

It doesn’t need to be perfect; it just needs you to stay on the right track long-term—and if the big picture is right, time will be on your side.
