explain to me in details bullet point what is Calorie deficit, Macros and how to achieve it accurately. Keep it short no nonsense post
Assistant: Here’s a short, no-nonsense, accurate breakdown:[edit | edit source]
Here’s a short, no-nonsense, accurate breakdown:
1. Calorie Deficit (Fat Loss Rule #1)[edit | edit source]
- Definition: You lose fat when you eat fewer calories than your body burns.
- Formula: Calories In < Calories Out
- 1 kg fat ≈ 7,700 calories
- Safe deficit: - 300–500 kcal/day → sustainable fat loss - 500–750 kcal/day → faster, harder to maintain
- Too aggressive = muscle loss, fatigue, rebound eating
2. Macros (What calories are made of)[edit | edit source]
Macros = Protein, Carbs, Fats
Protein (Most important)[edit | edit source]
- 4 kcal/g
- Preserves muscle, increases satiety
- Target: - 1.6–2.2 g per kg bodyweight
- Examples: chicken, fish, eggs, lean beef, whey
Carbohydrates[edit | edit source]
- 4 kcal/g
- Main energy source
- Adjust based on activity level
- Examples: rice, potatoes, fruit, oats
Fats[edit | edit source]
- 9 kcal/g
- Hormones & health
- Minimum: 0.6–0.8 g per kg bodyweight
- Examples: olive oil, nuts, eggs, fatty fish
3. How to Achieve It Accurately (No Guessing)[edit | edit source]
- Step 1: Calculate maintenance calories (TDEE)
- Step 2: Subtract 300–500 kcal
- Step 3: Set protein first, then fats, carbs last
- Step 4: - Weigh food (raw weight preferred) - Track using MyFitnessPal / Cronometer
- Step 5: Track weekly average weight, not daily
- Step 6: If no loss after 2 weeks → reduce 100–150 kcal
4. What Actually Matters[edit | edit source]
- Calories determine fat loss
- Protein determines muscle retention
- Carbs & fats determine performance & adherence
- Consistency > perfection
If you want, I can calculate your exact calories & macros in under 2 minutes.
