The Truth About Exercise and Weight Management: Can Exercise Help You Lose Weight? A Coach Explains Compensation Mechanisms and the Division of Labor with Diet

“Coach, I’m clearly exercising, so why is my weight stuck?”

I’ve heard this exact sentence probably over a thousand times in the past fifteen years.

I remember a student in his early forties, a desk worker named A-Zhe, who came to me for the first time with a tone bordering on grievance: “I ride my bike three times a week, an hour and a half each time, and I’ve pushed my average speed to nearly 30 km/h. My Garmin shows I burn over 700 kcal per ride. That’s over a dozen rides a month, so how come my weight hasn’t dropped a single kilogram?” He swiped through his cycling computer records one by one—the numbers looked great, with power, heart rate, and elevation gain all properly tracked.

I didn’t rush to answer. Instead, I asked him: “So after your rides, what do you have for dinner?”

He froze for a moment, then smiled a little sheepishly: “Well… I figured since I exercised today, I’d treat myself—braised pork rice with a fried chicken leg, plus a half-sugar bubble milk tea.”

At that moment, the answer was already crystal clear. In this article, I want to lay out plainly something I’ve verified countless times over the years—through my students, in the literature, and on my own body: Can exercise actually help you lose weight? If it can, what role does it play? And if it can’t, then what are all these sweat and tears worth?

This is not an article meant to dampen your enthusiasm for exercise. Quite the opposite—I hope that after reading this, you’ll put exercise back in its “proper place,” and then, with the right expectations and the right methods, truly manage your weight well and sustainably.

After all these years of coaching students, I’ve found that what frustrates people most isn’t “not being able to do it,” but rather “trying hard while heading in the wrong direction.” A-Zhe wasn’t lacking effort—he dutifully rode three times a week, more disciplined than most. What he lacked was simply a correct conceptual framework. Once he understood the real relationship between exercise, diet, and compensation, the same effort produced wildly different results. That’s why I always say that when it comes to weight loss, understanding the concepts first matters more than grinding away blindly. This article aims to help you get past that conceptual hurdle first.

Let’s Bust a Myth First: Exercise Burns Far Fewer Calories Than You Think

Let’s start with the harshest math.

Many people imagine exercise-based weight loss like this: “I burned 700 kcal today, and one kilogram of fat is roughly 7,700 kcal, so if I just exercise for eleven days, I’ll lose one kilogram!”

Sounds reasonable, right? But in reality, almost no one loses weight that way. So where’s the problem?

The Calorie Numbers on Your Devices Are Optimistic by Nature

First, the calorie expenditure shown on sports watches, spin bikes, and treadmills is “estimated” using formulas based on your weight, heart rate, and speed—not actually measured. These estimates tend to run high, especially on consumer-grade devices, where errors of 20% to 30% are common. You think you burned 700, but the real number might be just over 500.

Exercise Calories Must Be Subtracted from What You’d Burn Anyway

Here’s an even more important concept: even if you lay on the couch all day without moving, your body burns calories just maintaining breathing, heartbeat, body temperature, and organ function. That’s called your basal metabolic rate (BMR). So when you ride for an hour and “extra” burn calories, strictly speaking, you need to subtract what you would have burned lying down during that hour anyway. The truly “additional” calories burned because of exercise are actually even fewer than what your device shows.

I often use this analogy with my students: The calorie deficit exercise can create is more like pocket money from a part-time job, not a full-time salary. In theory, you could buy a house with part-time pocket money, but it would be extremely hard, and one big meal could easily wipe it all out.

A Real-World Comparison to Make It Click

I love showing students a comparison table so they can see with their own eyes the gap between “what exercise burns” and “what eating puts in.” Let’s take a person weighing 70 kg and look at roughly how much common exercises burn, compared to the calories in common Taiwanese foods:

Exercise (approx. 30 minutes)	Rough Estimate Burned	Common Taiwanese Food	Rough Estimate Calories
Easy jogging	About 250 to 350 kcal	A serving of Taiwanese fried chicken (medium)	About 500 to 700 kcal
Moderate-intensity cycling	About 200 to 300 kcal	A full-sugar pearl milk tea (700ml)	About 450 to 650 kcal
Brisk walking	About 130 to 180 kcal	A pineapple bun	About 350 to 450 kcal
Swimming	About 250 to 400 kcal	A serving of braised pork rice with braised egg	About 550 to 700 kcal

(These are rough ranges; actual numbers vary by weight, intensity, and metabolism. They’re meant to build intuition.)

See the point? The calories you burn through half an hour of hard exercise are often offset—or even exceeded—by a single snack or drink. This isn’t to say you shouldn’t exercise; it’s to make you realize that trying to “out-exercise” overeating is mathematically a losing game. Skipping a serving of fried chicken is far easier than running an extra half hour.

The Real Key Word: Compensation Mechanism

If it were just inflated calorie estimates, that would be simple enough. The real culprit behind exercise’s underwhelming weight-loss results is something called “energy compensation.”

This is also one of the hottest and most eye-opening areas in exercise physiology research in recent years. Simply put: when you create a calorie deficit through exercise, your body uses various ways you’re not even aware of to quietly fill that deficit back in. Your body is inherently resistant to weight loss—it treats body fat as survival reserves and won’t let it go without a fight.

According to a systematic review and meta-analysis pooling 51 trials (Beaulieu et al., 2021, published in Obesity Reviews), in the short term, people’s food intake on “average” does not fully compensate for the calories burned through exercise. But the research also emphasizes: individual variation is enormous. Some people barely compensate at all, while others over-compensate and end up gaining weight the more they exercise. And in long-term studies lasting 26 weeks or more, the actual weight lost tends to be only about 30% of what the calorie formulas would predict.

That “30%” figure is something I believe anyone trying to lose weight through exercise should etch into their brain. You think you’ll lose ten kilograms, but you might actually only lose three—it’s not that you’re not trying hard enough; it’s that your body is playing a compensation game with you.

It’s worth clarifying that the research cited here reflects “group averages.” The point is to remind you that “exercise’s weight-loss effect is often overestimated and comes with compensation”—not to say everyone will only lose 30%. Some people compensate very mildly and get good results from exercise; others compensate heavily and find it harder and harder to lose weight. Which type you are, you can only know by testing it yourself—which is exactly why I emphasize food logging so much, because it’s the only way to see your own compensation patterns clearly.

Compensation happens through three main pathways. Here’s a table I’ve put together for you:

Compensation Pathway	What the Body Does	Your Subjective Experience	Impact Size
Eating more (energy intake)	Post-exercise ghrelin rises and satiety signals drop, making you hungrier and less able to stop	“I’m so hungry after working out” “I want to treat myself”	The biggest factor, and the easiest to lose control of
Moving less (spontaneous activity)	Non-exercise activity thermogenesis (NEAT) drops after exercise—you walk less, lounge on the couch, skip the stairs	“I already exercised today, I’m tired and want to do nothing”	Often completely overlooked
Metabolism becoming more frugal (adaptive thermogenesis)	The body lowers basal metabolism, maintaining the same functions with fewer calories	Almost imperceptible; you just see the weight stuck	Large cumulative impact over the long term

Case Study: The Runner Who Got Hungrier the More She Trained

I once coached a female student, Xiao-Ting, who was preparing for her first half marathon. As her training volume ramped up, her weight didn’t drop—it actually increased by 1.5 kilograms. She was very frustrated. I asked her to keep a food diary for two weeks, and the picture became clear: After every long run, she would unconsciously eat an extra afternoon snack, rationalizing it with “I deserve this.” Her long run burned 600 kcal, but that slice of cake and latte was 700 kcal—a compensation of over 100%, putting her in a deficit.

She didn’t lack willpower; her body’s hunger signals were amplified after exercise. This is a physiological response, not a moral failing. We didn’t tell her to run less; instead, we redesigned her post-run nutrition, and the problem was solved.

Case Study: The Engineer Whose Results Were Quietly Eaten by NEAT

Here’s another classic example of the second type of compensation. My student Da-Wei was an engineer in the tech industry, already sedentary by nature. To lose weight, he started running for 40 minutes every morning. After a month, his weight hadn’t budged, and he was baffled because he felt he had his diet under control.

I had him wear a pedometer to track his activity during “non-exercise hours,” and the truth emerged: Since he started his morning runs, his daily step count during the day had actually dropped by 30%. Because he was tired after his morning run, he stayed glued to his chair all day at work, even skipping his usual habits of walking to buy coffee and taking the stairs, reasoning, “I’ve already exercised today.” The extra 300-400 kcal he burned in the morning was largely offset by the decrease in his daytime activity.

This is what’s called a drop in Non-Exercise Activity Thermogenesis (NEAT)—it doesn’t show up on any app, you’re completely unaware of it, yet it genuinely eats away at your efforts. Our solution was simple: we changed his morning runs to every other day with slightly lower intensity, and required him to get up and walk around every hour during the day and take the stairs during his commute, regardless of whether he exercised. A month later, his weight finally started to budge.

The lesson from this case is: exercise shouldn’t make you “less inclined to move” the rest of the time. The ideal state is to stay active in daily life in addition to exercise; the sum of both is your true total expenditure.

So, Does Exercise Actually Work? Of Course It Does—Just in the Right Places

At this point, you might be feeling a bit discouraged: “So, exercise is useless then?”

Absolutely wrong. I want to make this very clear: exercise is extremely important for weight management, but its main battlefield isn’t “rapid weight loss”—it’s in these things that diet alone can’t achieve:

• Maintaining weight loss and preventing regain: This is exercise’s most valuable role. Many studies point to the fact that people who successfully maintain their weight long-term almost all have a regular exercise habit. Using diet to bring the weight down and exercise to keep it off—that’s the golden combination.
• Improving body composition: At the same 65 kilograms, someone with 30% body fat and someone with 20% body fat look like completely different people. Resistance training can preserve or even increase muscle mass, helping you “lose weight and look good” rather than “lose weight and look deflated.”
• Protecting metabolism: Dieting alone for weight loss causes you to lose muscle along with fat, which lowers your basal metabolic rate, making it progressively harder to lose weight. Combining it with exercise, especially strength training, can significantly reduce muscle loss.
• Health benefits far beyond the number on the scale: Blood pressure, blood sugar, blood lipids, cardiovascular fitness, sleep, mood, insulin sensitivity… these improvements often happen before you even lose a pound. Even if your weight doesn’t change at all, an active person with obesity is far healthier than an inactive person with obesity. I say this to every student who’s anxious about their weight.

The World Health Organization’s (WHO) 2020 physical activity guidelines recommend that adults accumulate 150 to 300 minutes of moderate-intensity, or 75 to 150 minutes of vigorous-intensity aerobic activity per week, plus muscle-strengthening activities involving all major muscle groups on two or more days per week. It’s important to note that this recommendation is for “overall health,” not specifically designed for rapid weight loss—which again confirms that the value of exercise goes far beyond the number on the scale.

The Division of Labor Between Exercise and Diet: A Phrase to Remember

There’s an old saying in the fitness world that, while a bit simplistic, points in the right direction:

Weight loss happens in the kitchen; health happens in the gym.

Let me reinterpret this division of labor more precisely:

Goal	Primary Tool	Supporting Tool	Coach’s Note
Create a calorie deficit, lose weight	Diet (portions, choices)	Exercise	The deficit mostly comes from what you don’t eat, not from sweating more
Maintain muscle, sculpt your physique	Resistance training	Adequate protein	Don’t stop lifting, especially during fat loss
Maintain results, prevent regain	Regular exercise habit	Diet without indulgence	This is exercise’s most irreplaceable value
Improve health markers	Exercise (cardio + strength)	Diet quality	Even if the scale doesn’t move, your health is improving

Once you understand this table, you won’t make the mistake of “using exercise to offset bad eating.” That’s using a supporting tool against the primary tool—it never adds up.

Why Is a “Calorie Deficit” So Hard to Maintain?

You might ask: since weight loss is just creating a calorie deficit, why not just eat less? Why is it so hard?

The difficulty lies in the fact that your body fights this deficit with everything it has. When you start eating less, ghrelin (the hunger hormone) rises, making you want to eat more; leptin (the satiety hormone) falls, making it harder to feel full; your basal metabolic rate dips slightly (the adaptive thermogenesis mentioned earlier); and even your unconscious daily activity may quietly decrease. This entire “anti-weight-loss” mechanism is a survival instinct honed over millions of years of evolution—in times of food scarcity, resisting weight loss was a life-saving advantage. But in our modern environment of food abundance, it becomes a stumbling block on the road to weight loss.

Understanding this should make you a bit kinder to yourself. Hitting a plateau isn’t because you have weak willpower; it’s because you’re fighting a very powerful physiological system. So strategically, what we need to do isn’t to clash head-on (aggressive dieting), but to create a “gentle, sustainable” deficit that doesn’t trigger the body’s full-scale resistance, while using exercise to preserve muscle and adequate protein to maintain satiety and metabolism. That’s the smart way to play.

Common Mistakes and Fixes: I’ve Seen Too Many People Fall Into These Traps

Mistake 1: Using “Exercise Rewards” as an Excuse to Binge

This is the number one killer, as seen in the earlier examples of A-Zhe and Xiao-Ting.

Fix: “Decouple” exercise and diet. Exercise is exercise; it’s for health and physique, not a license to binge. I usually advise students that if they’re genuinely hungry after a workout, they should prioritize protein (unsweetened soy milk, boiled eggs, chicken breast, unsweetened yogurt) over refined carbs and sugar. Protein is more satiating and also aids muscle repair.

Mistake 2: Only Doing Cardio, Never Touching Weights

Many people, desperate to lose weight, go crazy with running and spinning but do no strength training. The result is that they lose weight, but a portion of it is muscle. They become soft and flabby, their metabolism worsens, and once they stop, they quickly regain the weight.

Fix: Schedule at least two full-body resistance training sessions per week. You don’t need a gym membership; bodyweight exercises like squats, push-ups, lunges, and rows can be done at home. Muscle is your metabolic engine; preserving it is preserving your capital for weight loss.

I especially want to clarify something for my female students who “fear that lifting weights will make them bulky like a female bodybuilder”: It’s nearly impossible for the average person to build a bodybuilder’s physique through resistance training alone—that requires extreme training volume, diet, and time commitment. The main purpose of lifting during a fat-loss phase is to “preserve existing muscle and prevent muscle loss during weight loss,” so that when you slim down, you look toned and firm, not saggy. At the same body weight, someone with muscle simply looks leaner and more defined. So regardless of gender, you shouldn’t drop strength training during a fat-loss phase—this is my firm stance with every student.

Mistake 3: Treating the Watch’s Calorie Count as Gospel and Eating It All Back

As mentioned earlier, calorie counts from wearable devices are often overestimated. If you trust that number and eat back “exactly” what it says, you’re actually in a surplus.

Fix: Mentally “discount” the calories burned during exercise by 30%, or just treat it as zero. You’ll find that when you stop using exercise calories to justify eating, the deficit naturally holds.

Mistake 4: Sitting All Day After Exercise, Sending NEAT to Zero

This is the most invisible trap. You work hard for an hour of exercise in the morning, but then you’re barely active for the remaining 23 hours because you’re “tired,” and a large chunk of the extra calories you burned all day is offset by the drop in spontaneous activity.

Fix: Consciously maintain your daily activity level. Get up to fill your water bottle, take the stairs, get off the bus one stop early and walk. These “non-exercise” activities accumulate and often contribute to your calorie deficit more than you’d imagine.

Mistake 5: Only Watching the Scale, Ignoring Other Progress

Body weight is affected by water, glycogen, salt, and the menstrual cycle for women; fluctuating one or two kilograms within a day is par for the course. Staring at a single number makes it easy to break down and give up during normal fluctuations.

Fix: Use multiple measures to track progress—waist circumference, how your pants fit, body fat, strength gains, not getting winded on climbs, and sleep quality. Weight is just one measure, and it’s often the most deceptive one.

Actionable Advice for Readers at Different Levels

Everyone starts from a different point, so I’ll break the advice down by level—just find where you fit.

If You’re a Complete Beginner / Just Starting Out Overweight

At this stage, the most important things are building habits, avoiding injury, and not giving up. Forget about high intensity for now.

• Cardio: Start with three times a week, 30 minutes of brisk walking or easy cycling each session. Intensity should be at a level where “you can talk but can’t sing” (roughly 60% to 70% of your maximum heart rate. If you’re 40, that’s an estimated heart rate between 108 and 126 bpm—just a reference).
• Diet: Don’t go on a drastic diet yet. The first step is just one thing—swap sugary drinks for sugar-free ones. Taiwan’s hand-shaken drink culture is strong; a full-sugar bubble tea can have calories close to a full meal. Just cutting this out alone, many people feel a difference within a month.
• Strength: Twice a week, do the simplest squats, wall push-ups, and sit-to-stands, three sets each.
• Mindset: Set your goal as “did I get three sessions in this week,” not “how many kilos did I lose this week.”

If You’re an Intermediate Exerciser Stuck at a Weight Plateau (Like A-Zhe)

Your problem usually isn’t the amount of exercise, but unmanaged compensation and unfocused nutrition.

• Keep an honest food diary for two weeks: No need to weigh grams, but write down every bite, especially the post-workout meal and snacks. You’ll see with your own eyes how the deficit gets filled back in.
• Switch your post-workout recovery to protein, and ditch the “reward-style” high-sugar, high-fat treats.
• Add or increase resistance training, aiming for it to make up about half of your weekly training volume.
• Check your NEAT: Are you collapsing on the couch all day after your workout?

If You’re Advanced / Looking to Change Body Composition

You already know a lot; this stage is about fine-tuning.

• Periodize your calorie and training plan: During a cutting phase, keep the deficit moderate (roughly 300 to 500 kcal per day, avoiding overly aggressive cuts that lead to muscle loss and metabolic slowdown), paired with adequate protein (a common general recommendation is 1.6 to 2.2 grams per kilogram of body weight per day; consult a dietitian for individual situations).
• Maintain intensity in weight training, training with a “maintain strength” mindset. Don’t chase new PRs during a cut.
• Use your environment wisely: Taiwan’s summers are hot and humid. When cycling or running outdoors, pay special attention to hydration and electrolytes to avoid heatstroke. Try to avoid the hottest part of the day (roughly 11 a.m. to 3 p.m.) and train in the early morning or evening instead. Indoor cycling and gyms are great options during the scorching heat and the rainy season.

A Ready-to-Use Weekly Template

Many clients ask me for a framework they can just “follow.” Below is a common weekly template I give to intermediate clients who “have a training base, want to lose fat, but don’t want to lose muscle.” You can adjust it to your own situation:

Day	Training Content	Focus & Nutrition Pairing
Monday	Full-body resistance training, 45 min	Squats, rows, presses; protein after training
Tuesday	Moderate-low intensity cardio, 40 min (brisk walk or easy cycling)	Keep it easy, conversational pace
Wednesday	Rest or stretching, walking	Active recovery, maintain daily step count
Thursday	Full-body resistance training, 45 min	Change exercise angles, maintain intensity
Friday	Interval cardio, 25 min	Alternate fast and slow, efficient and time-saving
Saturday	Longer, low-intensity cardio (cycling or hiking)	Taiwan’s suburban hills and riverside paths are great options
Sunday	Complete rest	Sleep well, let your body recover

This template includes two strength sessions, multiple cardio sessions, and adequate recovery, aligning with the WHO recommendations mentioned earlier. The point isn’t to “copy it exactly,” but to grasp three principles: include strength, include cardio, include recovery. As for the dietary deficit, always remember that’s the main driver of weight loss; training is just the foundation that protects muscle and health.

How Much Protein? A Reference Table

The biggest fear during a cut is losing muscle, and protein is key to protecting it. I’ve compiled common daily protein reference amounts below (using a 60 kg person as an example). Remember, these are “general reference ranges”—adjust based on your individual health and a dietitian’s advice:

Population / Situation	Common Recommended Range (per kg body weight / day)	Example for 60 kg Person	Notes
General sedentary adult	~0.8 to 1.0 g	~48 to 60 g	Maintains basic needs
Regularly exercises, wants to maintain muscle	~1.2 to 1.6 g	~72 to 96 g	General athletic population
Cutting phase, wants to preserve muscle	~1.6 to 2.2 g	~96 to 132 g	Especially important during a deficit

Getting enough protein in Taiwan is actually easy: unsweetened soy milk, boiled eggs, chicken breast, tuna, tofu, unsweetened yogurt, and lean meat from traditional markets are all great sources. If you have kidney disease or other chronic conditions, you must consult your doctor or dietitian before increasing protein intake—don’t do it on your own.

Practical Reminders for the Taiwan Context

Finally, here are a few very local, very practical tips that I specifically emphasize with my Taiwanese clients.

Calorie Traps for Eating Out: Eating out in Taiwan is convenient and delicious, but calorie-dense. Braised pork rice, fried foods, thickened soup stews, and the three side dishes in a bento box are often heavy on oil and salt. A simple principle—treat “sauces” and “fried” as warning signs when ordering. Opt for boiled, braised, or steamed options when possible, get half the rice, and add a portion of blanched vegetables. These small tweaks have a surprisingly powerful long-term effect.

The Hand-Shaken Drink and Late-Night Snack Culture: These are the two biggest enemies of weight management for Taiwanese people. As mentioned earlier, cut out sugary drinks first. For late-night snacks, I suggest setting a “kitchen closing time”—no eating after that—to give your body a consistent fasting window.

Use Taiwan’s NHI and Professional Resources: If you have the “three highs” (high blood pressure, high blood sugar, high blood lipids), a family history of diabetes, or are significantly overweight and want to address it seriously, please see a doctor first. Medical care is accessible in Taiwan, and NHI coverage is relatively generous. Many hospitals have weight management clinics, nutrition counseling, and metabolic syndrome screenings. If you have any cardiovascular concerns before starting an exercise program, get a basic check-up first—safety comes first. This article provides general principles and cannot replace a doctor’s assessment of your individual situation.

Climate and Venues: Taiwan is hot and humid. Sweating a lot in summer can make you think you’re “burning a lot,” but sweat volume and calorie expenditure aren’t proportional. Don’t be fooled by the temporary drop on the scale from dehydration. During the rainy season, indoor exercise, community gyms, and bodyweight training at home are all great backup plans. Don’t let the weather become an excuse to break your habit.

Frequently Asked Questions (FAQ)

These are the questions I’ve been asked to death over my years of coaching. Here’s a consolidated answer.

Q1: Does Fasted Exercise Burn More Fat?

Fasted exercise does use a bit more fat as fuel at that moment, but “which fuel you burn at that moment” and “how much total fat you lose over the day” are two different things. What truly determines whether you lose fat is your total calorie balance over the day and the week, not the fuel ratio of a single workout. Fasted exercise works for some people, but others get dizzy, perform worse, or even end up hungrier and eat more. There’s no one-size-fits-all answer; it depends on how your body responds. People with blood sugar issues especially shouldn’t do high-intensity fasted exercise on their own—ask your doctor first.

Q2: Is Spot Reduction Possible? Like Doing Tons of Ab Work to Lose Belly Fat?

Unfortunately, there’s no such thing as spot reduction. When you hammer a specific area, you’re training the muscle there, but where fat comes off first is determined by genetics and your overall body fat percentage—you can’t dictate it. To lose belly fat, the answer is still the same old story: overall fat loss (via a dietary deficit) + full-body exercise + preserving muscle. You could do sit-ups until dawn, and that layer of fat on your belly won’t magically disappear because of it.

Q3: How many kilograms per week is considered healthy to lose?

The common safe recommendation is 0.5 to 1 kg per week (or roughly 0.5% to 1% of your starting body weight as a rough reference). Losing weight too quickly usually means you’re losing water and muscle, and it makes rebound weight gain and binge eating much more likely. Going slow is actually the fastest path. Weight loss is a marathon, not a sprint—that’s what I always tell my clients.

Q4: Is it normal for my weight to fluctuate up and down every day?

Perfectly normal. Body weight is affected by water, salt intake, glycogen stores, bowel movements, and the menstrual cycle in women. A fluctuation of one to two kilograms within a day is completely ordinary. It’s recommended to weigh yourself under consistent conditions (e.g., in the morning after waking up, after using the bathroom, on an empty stomach) and look at the weekly average trend rather than a single day’s number. Don’t panic just because you’re 0.8 kg heavier one day—it might just be that you ate something salty the night before.

Q5: Is it okay to rely on diet alone without exercise?

In the short term, you can lose weight through diet alone, but I strongly advise against “no exercise at all.” The reasons were covered earlier: losing weight without exercise tends to cause muscle loss along with it, which lowers your metabolism, makes long-term maintenance harder, and increases the likelihood of regaining the weight. You’d also miss out on all the health benefits beyond the number on the scale that exercise provides. Diet is responsible for bringing the weight down; exercise is what makes you lose it healthily and keep it off.

Q6: I’m taking weight-loss supplements. Is that enough?

Many supplements on the market claim to boost fat burning or metabolism, but their effects are often limited—and some even contain questionable ingredients that carry health risks. No supplement can replace the fundamentals of dietary control and regular exercise. If you’re considering any supplement, or if you’re taking medication for a chronic condition, be sure to consult your doctor or pharmacist first to avoid interactions. Spending your money and energy on eating proper meals and building good habits is far more practical than buying supplements.

Conclusion: Putting exercise back where it belongs

Back to A-Zhe’s story. In the end, we didn’t increase his cycling volume. Instead, we focused on three things: no more fried chicken and bubble tea with milk after workouts, adding two strength-training sessions per week, and switching his hand-shaken drinks from full sugar to sugar-free. Three months later, he had lost 4 kg, his body fat dropped by nearly three percentage points, the same mountain climb felt noticeably easier, and his sleep improved.

He told me: “I had it all backwards. I thought exercise was for ‘canceling out’ bad eating, but what really needed to change was my mouth.”

And I’d like to add one more insight he shared later. Six months on, A-Zhe told me that what surprised him most wasn’t how many kilograms he’d lost, but things like “not being out of breath on the stairs, fewer red flags on my health check, and having more energy.” He said: “Coach, even if my weight never drops another gram, I won’t stop. Because what exercise has given me already goes far beyond that number on the scale.”

I’ve remembered that line ever since, because it perfectly echoes the core message I want to convey in this entire article—don’t narrowly tie the value of exercise to the number on the scale. When you treat exercise as a lifelong investment in your health rather than a short-term weight-loss tool, you’re actually more likely to stick with it, and the results last longer.

This is the core message I want to get across through this article:

• Can exercise help you lose weight? Yes, but the effect is more modest than you might think, and it can easily be offset by your body’s compensatory mechanisms.
• So should you still exercise? Absolutely. Exercise’s truly irreplaceable value lies in maintaining results, preserving muscle and metabolism, and delivering health benefits that go far beyond the number on the scale.
• Where is the main battleground for weight loss? At your dining table, in your choice of hand-shaken drinks, and in the decision you make for that post-workout meal.

Stop asking “Why am I not losing weight despite working out so hard?” and instead ask: “Have I held the line on my diet? Have I preserved my muscle? Has my daily activity level dropped?” Treat exercise as the foundation of long-term health and diet as the steering wheel of your weight. When each plays its proper role, you can lose weight healthily, keep it off for the long haul, and avoid rebound weight gain.

Sweating is great, but don’t let your sweat become a license to indulge. There’s no shortcut to healthy weight management, but it’s also not as complicated as you might think—get the concepts right, use the right methods, and give yourself enough patience, and the results will come. I wish you a steady and sustainable journey on this path.
