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.
