Why Most People Fail at Weight Loss (And How to Fix It Using Physics & Psychology)
Share
Most people don’t fail at weight loss because they’re weak or unmotivated — they fail because they’re fighting the wrong enemy.
They think the struggle is against carbs… sugar… hormones… metabolism… even time of day.
But the real problem is simpler — and far more human:
We misunderstand how energy works in the body — and we misunderstand how our brains behave under restriction.
Fat loss is not a mystery. It’s physics + psychology.
Once you understand both, everything becomes easier.
1. Physics First: The Body Cannot Break the Laws of Thermodynamics
Your body obeys the same laws of energy as engines, planets, and stars.
Energy cannot be created or destroyed — only transferred or stored.
This means:
- Eat more calories than you burn → you store the excess as fat.
- Eat fewer calories than you burn → your body uses stored fat for energy.
This is a calorie deficit, and it is the only mechanism that produces fat loss.
Decades of metabolic research confirm this.

Hall KD et al., Am J Clin Nutr (2012)
https://pubmed.ncbi.nlm.nih.gov/22434603/
No diet — Keto, fasting, low-carb, low-fat, vegan, carnivore — works unless it creates a deficit.
Physics does not negotiate.
2. Psychology: Why Humans Fail Even When the Science Is Simple
Even when people know what to do, they struggle.
Why?
Because the human brain hates:
- uncertainty
- restriction
- delayed reward
- inaccurate feedback
Three psychological traps destroy most diets.
Trap 1: People Guess Their Calories (and Humans Guess Wrong)
Every major study shows the same thing:
People underestimate calorie intake by 20–50%.
Reference: Lichtman SW et al., NEJM (1992)
https://pubmed.ncbi.nlm.nih.gov/1454084/
A teaspoon of peanut butter becomes “half a teaspoon.”
A cup of rice becomes “half a cup.”
200 kcal becomes “maybe 80–100.”
Fix this with tracking:
- MacroFactor (most accurate)
- MyFitnessPal
- Or even manual logging
- Estimate maintenance using TDEEcalculator: https://tdeecalculator.net
Fat loss requires data, not hope.
Trap 2: The Scale Lies (But Trends Don’t)
You might gain 1 kg overnight — not from fat, but from:
- water
- salt
- hormones
- glycogen
- digestion
- stress
This is why dieters get discouraged.
The correct scientific method:
Weigh daily → calculate weekly average → compare averages.
Reference: Daily weight variability —
Orsama AL et al., Obesity Facts
https://pmc.ncbi.nlm.nih.gov/articles/PMC5644907/
If your weekly average drops, you’re losing fat.
If it stays constant, you’re not in a deficit.
If it rises, you’re in a surplus.
Simple. Reliable. Emotion-free.
Trap 3: People Rely on Willpower Instead of Systems
Willpower fails. Systems don’t.
Build systems like:
- Pre-logging meals
- Eating the same breakfast/lunch each day
- Keeping protein high
- Increasing daily steps (NEAT)
- Doing 2–4 strength sessions weekly
- Keeping high-calorie foods out of the house
Your environment beats your motivation — every time.
3. Metabolism: People Overestimate Exercise & Underestimate Movement
Your TDEE (Total Daily Energy Expenditure) has four parts:
- BMR — calories burned staying alive
- NEAT — steps, movement, fidgeting
- TEF — digestion
- EAT — actual exercise
Most people think EAT (gym time) burns the most.
It doesn’t.
Walking (NEAT) burns far more across the day.
This is why increasing your steps is more effective than increasing your workouts.
But exercise does matter:
It protects your muscle while in a calorie deficit — critical for long-term fat loss.
This is where creatine and collagen help indirectly.
4. How Creatine Supports Fat Loss (Indirectly, But Powerfully)
Creatine does not burn fat.
But it helps you preserve muscle, maintain strength, and perform better during a deficit.
Benefits:
- Improved strength & performance
- Better training quality
- Muscle retention (higher metabolism)
- Better cognitive performance under low calories
Reference: Forbes/Candow review on creatine & muscle
https://pmc.ncbi.nlm.nih.gov/articles/PMC6518405/
During fat loss, strength is the first to drop.
Creatine helps protect it.

5. How Collagen Makes the Process Easier
Collagen doesn’t burn fat either — but it supports:
- Joint comfort during higher steps
- Skin elasticity during weight changes
- Tendon & ligament recovery
- Better sleep via glycine
- Gut lining integrity
Reference: Collagen peptides & skin physiology —
Proksch E et al., Skin Pharmacol Physiol
https://pubmed.ncbi.nlm.nih.gov/23949208/
A deficit without recovery support = burnout.
Collagen reduces friction.

6. The Fix: A Fat-Loss Blueprint Based on Physics and Psychology
Here is the system that works — every time:
1. Find your maintenance calories
MacroFactor / MyFitnessPal / TDEEcalculator.
2. Eat 300–500 kcal below your maintenance
This creates predictable fat loss without starvation.
3. Track your food
No guesses. Data only.
4. Lift weights 2–4× per week
Protect your muscle.
5. Walk 8–10k steps per day
Increase NEAT.
6. Take creatine daily (3–5 g)
Support strength, muscle, and energy.
7. Take collagen daily
Support joints, skin, recovery, sleep.
8. Use weekly weight averages — not daily emotions
Your trend is your truth.
This is how you win.
