How this is calculated
Formula: Estimated TDEE minus a moderate deficit with a high-protein macro allocation
The calculator estimates basal energy needs from your personal measurements and applies an activity multiplier to approximate total daily expenditure.
It creates a moderate calorie deficit rather than an extreme cut. This supports a more sustainable rate of loss, though actual results depend on adherence and changing energy expenditure.
Protein is prioritized to support lean tissue and satiety, dietary fat remains sufficient, and carbohydrate receives the balance for everyday activity and exercise.
Fat-loss planning ranges
| Factor | Common starting range | Purpose |
|---|---|---|
| Calorie deficit | 10–25% below TDEE | Creates gradual energy shortfall |
| Protein | 1.6–2.4 g/kg/day | Helps retain lean mass during a cut |
| Fat | 20–30% of calories | Supports essential functions and satisfaction |
| Rate of loss | 0.25–1% body weight/week | A practical monitoring range, not a guarantee |
Make a deficit easier to sustain
Choose filling foods with protein, fiber, and volume. Keep favorite foods in sensible portions so the plan remains realistic.
Example protein-forward fat-loss day
- •Breakfast: vegetable omelet, whole-grain toast, and berries
- •Lunch: tuna and bean salad with a lemon-yogurt dressing
- •Snack: cottage cheese with apple slices
- •Dinner: lean beef or tofu stir-fry with vegetables and rice
- •Dessert option: plain Greek yogurt with cocoa and fruit

Tips
- •Use weekly weight averages instead of reacting to one weigh-in.
- •Include protein and produce in each main meal.
- •Keep resistance training where appropriate to support lean mass.
- •Reduce the deficit if energy, sleep, mood, or training quality deteriorates.

Frequently asked questions
Fat loss comes from a sustained calorie deficit. A higher-protein allocation with adequate fat and flexible carbohydrate is often easier to follow than a rigid universal ratio.
