Scope: Food literacy · hub calories & macros · Yeh Bro System · food.
A calorie (technically a kilocalorie on labels) is a unit of energy. Your body uses that energy to stay alive, move, digest food, and recover from training. Cut vs bulk is mostly about whether you’re a bit under or over what you burn across weeks — not whether rice is “evil” after 6 pm.
TL;DR
- Energy in vs energy out drives fat change over weeks, with water/glycogen noise day to day.
- Deficit ≈ lose fat (if honest and sustained). Surplus ≈ gain weight (hopefully some muscle if you train).
- Macros (protein, carbs, fat) are how you split calories — they don’t repeal energy balance.
- Next: estimate maintenance · macro split basics.
Cut vs bulk without mysticism
| Goal | Energy story | Lifter job |
|---|---|---|
| Hold weight | Near maintenance | Build skill, sleep, protein habit |
| Lose fat | Modest deficit | Keep training quality — cutting guide |
| Grow | Small surplus | Don’t dirty-bulk the cut away — lean bulk |
The scale lies short-term: sodium, carbs, creatine water, hormones, stress. Use trends + waist/photos — tracking weight / waist / photos · sodium / scale panic.
Where “calories out” comes from (first-pass glossary)
You’ll see these everywhere — expand once, then move on:
| Term | Plain English |
|---|---|
| BMR / RMR | Basal / resting metabolic rate — energy to stay alive at rest (formulas estimate; they’re not lab truth) |
| TEF | Thermic effect of food — digesting/processing what you eat (protein costs a bit more than fat) |
| NEAT | Non-exercise activity thermogenesis — fidgeting, steps, standing, chores |
| EAT | Exercise activity — the gym, sport, hard cardio |
| TDEE | Total daily energy expenditure — roughly the sum of the above |
You don’t need a PhD. You need a workable maintenance estimate, then a nudge. Full method: estimate maintenance calories.
Macros sit inside calories
- Protein — muscle retention / satiety priority — protein targets
- Carbs — training fuel and adherence — carb totals vs timing
- Fat — hormones, vitamins, food enjoyment — keep a floor — dietary fat floors
If calories are wrong, perfect 40/40/20 pie charts still won’t save the phase.
