I hardly eat anything, and I'm still not losing weight! - Expert Personal Trainers in Nashville (2023)

Have you ever felt like you hardly eat anything, but you’re still not losing weight? (Or had a personal training client who has felt this way?)

Despite doing everything they “should” be doing, including eating less (maybe a LOT less) they’re still not losing weight. In fact, they might even be gaining weight!

A quick internet search will give you lots of explanations — “broken” metabolism, starvation mode, insulin resistance, cannibalizing lean muscle, hormone deficiencies, to name a few.

If you’re hardly eating anything but you’re still not losing weight, is there something wrong with you? Is your body broken? Is it all in your head?

Or can you actually gain weight from under-eating?

Let’s look at some facts first, then some suggestions for why you may not be losing weight:

Facts first — Calories DO matter.

  • If we eat more calories than we expend, we gain weight.
  • If we eat fewer calories than we expend, we lose weight.

In the end, that energy balance is what will determine whether you gain or lose weight.

Everybody knows that.

BUT…it’s not just simple math.

Measuring both calories (the “in”) and metabolism (the “out”) is imprecise.

The nutrition databases (like the free MyFitnessPal app) are just ballpark figures for how many calories certain foods contain.

The nutrition labels on food are a good estimate/average, but research shows that they are often 20 or 30 percent off!

Same goes for guessing how many calories you burn.

  • Your apple watch will give you a target.
  • Your fitness app will give you a different target.
  • The Harris-Bennedict equation, or a free online tool to determine your optimal calorie intake will give you other numbers.
  • Your treadmill or elliptical trainer will display calories burned.

So, most of the time, we have to guess. And nutrition research shows that our guesses aren’t very good 🙁

There’s no good way for us to truly know the actual energy in (calories consumed) and the actual energy out (calories burned).
Ballparking and experimenting is all we can do.

Our biggest problem with not losing weight is perception.

As human beings, we’re bad at correctly judging how much we’re actually eating and expending. We tend to think we eat less and burn more than we do — sometimes by as much as 50 percent!

(Interestingly, people who are working out to gain weight often have the opposite problem — They overestimate their food intake and underestimate their exercise expenditure.)

(Video) Intermittent Fasting But NOT LOSING WEIGHT

More than anything, it’s that we struggle to estimate portion sizes and calorie counts.

This is especially difficult in today’s western society, when plates and portions are bigger than ever. Calorie-dense, incredible tasting, highly brain-rewarding “foods” are plentiful, cheap, and encouraged with advertising.

(I once had a client discover he was using ten tablespoons of olive oil — 1200 calories — rather than the two tablespoons — 240 calories — he thought he was using as his salad dressing. Yikes!)

Sabotaging your weight loss efforts

Let’s take an example of how “calorie creep” can sabotage your weight loss efforts, even when you almost always eat well.

A colleague of mine, Dr. John Berardi, went out to eat with some friends at a well-known restaurant chain. He ordered one of their “healthier” meals that emphasized protein, veggies, and “clean” carbs. Then since it was a special occasion, he finished off dinner with cheesecake for dessert.

Curious about how much energy he’d consumed, he looked it up.

Five. Thousand. Calories.

Imagine yourself in this same scenario — You’ve been under-eating almost every meal during the week and maintaining an estimated negative energy balance of about -3,500 calories. Great week, good job! Then, during one single meal (a healthy menu option plus a splurge dessert), you accumulated 5,000 calories.

That one meal would put you in a theoretically positive energy balance for the week (+1,500 calories), leading to weight gain!

No wonder we all lose our minds after eating 20 “perfect” meals in a row and 1 “not so bad” meal, and gain weight!

(Video) Want To Lose Weight? Doctors Say It’s Time To Stop Counting Calories

THIS is why we feel like our metabolism is broken, or that there’s no hope — because we were just about perfect.

But it has nothing to do with being “good” or not, it’s just that there were more calories for the week than you knew.

We don’t defy the laws of human physiology. We just think we do, because we’ve made assumptions about portions and calories that were not correct.

Calories burned — your metabolism

You may have heard that one pound of fat is 3,500 calories, so if you cut 500 calories per day, you’ll lose a pound per week.

That looks good on paper, but human metabolism isn’t that cut and dried. The human body is a complex and dynamic system that responds quickly to changes.

When you undereat, especially over a longer period, your complex body adapts.

Here’s an example of how undereating might play out:

  • You expend less energy in digestion because you’re eating less.
  • Your resting metabolic rate goes down because you weigh less.
  • Calories burned through physical activity go down since you weigh less.
  • Non-exercise activity (daily-life movement) goes down and you subconsciously expend less energy through the day.
  • Your digestion slows down, and you absorb more energy from your food.

Your body will also adjust hormonal feedback and signaling loops. For instance:

  • Appetite and hunger hormones go up (i.e. we want to eat more, are more stimulated by food cues, may have more cravings).
  • Satiety hormones go down (which means it’s harder for us to feel full or satisfied).
  • Thyroid hormone goes down.

Your planned 500 calorie daily deficit can quickly become 400, 300, or even 200 calories (or fewer), even if you intentionally exercise as much as you had before.

And, speaking of exercise, the body has similar mechanisms when we try to out-exercise too much food.

(Video) Not Losing Belly Fat? Watch this (+Flat Belly Tips) | Joanna Soh

For example, research suggests that increasing physical activity above a certain threshold (by exercising more) can trigger:

  • More appetite and more actual calories eaten
  • Increased energy absorption
  • Lowered resting or basal metabolism
  • Less fidgeting and spontaneous movement

There are other factors, such as the health of our microbiome, our feelings about eating less (i.e. whether we view eating less as a stressful thing), and so on.

The point is that your metabolism is much more complicated (and interdependent) than most people realize.

Not losing weight

All of this means that when you eat less, you may lose less weight than you expect. Depending how much less you eat, and for how long, you may even re-gain weight in the long run thanks to these physiological and behavioral factors.

  • The calorie counts of the foods you’ve logged might be higher than expected, either because of erroneous labeling or because of small errors in your own measurement.
  • Your energy needs might be lower than calculated (or even measured).
  • You’re expending less energy through movement than your fitness tracker or exercise machine suggests.
  • You have less lean muscle than you think.
  • You’re absorbing more energy from food than you realize (for instance, if your gastrointestinal transit time is slow, or your microbiota are really good at extracting nutrients).

Our own unique responses, genetics, physiology, and more means that our calorie needs will differ from the needs of others, or the numbers predicted by nutrition and exercise calculators (and the equations they rely on).

You’re an individual, and your body will probably not respond the same as someone else’s.
