Build calorie targets and timed meals for fasting goals. Balance macros, meals, and routines with simple planning support daily.
| Profile | Weight | Height | Activity | Protocol | Goal | Estimated Calories |
|---|---|---|---|---|---|---|
| Male, 30 years | 75 kg | 175 cm | Moderate | 16:8 | Maintain | 2550 kcal |
| Female, 28 years | 62 kg | 165 cm | Light | 14:10 | Fat Loss | 1700 kcal |
| Male, 36 years | 84 kg | 180 cm | Active | 18:6 | Muscle Gain | 3150 kcal |
BMR: Mifflin-St Jeor equation estimates resting calorie needs.
Men: BMR = (10 × weight kg) + (6.25 × height cm) - (5 × age) + 5
Women: BMR = (10 × weight kg) + (6.25 × height cm) - (5 × age) - 161
TDEE: TDEE = BMR × activity factor
Goal Calories: Target Calories = TDEE ± adjustment for fat loss or muscle gain
Protein: Protein grams = body weight in kg × selected protein target
Fat: Fat grams = (target calories × fat %) ÷ 9
Carbs: Carb grams = remaining calories ÷ 4
Eating Window: Eating hours = 24 - fasting hours
Intermittent fasting works best with clear calorie planning. Many people track only fasting hours. That is not enough. Your body still needs balanced energy, protein, fiber, and water. A structured meal planner solves that gap. It helps you match your eating window with realistic intake targets.
Fasting changes meal timing. It does not remove energy balance. Weight loss still depends on a calorie deficit. Maintenance needs stable intake. Muscle gain needs extra fuel and enough protein. This calculator estimates BMR first. Then it applies activity and goal adjustments. That creates a practical daily calorie target.
Macros improve meal quality inside a shorter eating window. Protein supports recovery and fullness. Fat supports hormones and meal satisfaction. Carbohydrates help performance and training output. A fasting plan without macro control can feel random. This tool divides calories into useful daily gram targets for each major nutrient.
Your eating window shapes meal spacing. A 16:8 plan may fit three meals. An 18:6 plan may fit two larger meals. OMAD needs dense nutrition in one sitting. This calculator converts fasting hours into an eating schedule. It also splits calories and macros across your selected meal count.
Meal timing can improve consistency. Starting your eating window at the same time builds routine. Placing protein evenly across meals may improve adherence. Hydration and fiber also matter. They support digestion and appetite control. That is why this planner includes water and fiber goals with meal suggestions.
This calculator helps beginners and experienced fasters. It works for fat loss, maintenance, and lean gain. It is useful for balanced, vegetarian, vegan, high protein, and lower carb patterns. Use it to create a daily plan. Then adjust based on training, hunger, sleep, and weekly progress.
No. Fat loss still depends on total calorie intake, activity, and consistency. Fasting mainly helps some people manage timing and appetite better.
Most beginners start with 12:12 or 14:10. These plans are easier to follow and usually create less hunger than aggressive fasting windows.
Protein helps preserve lean mass, supports recovery, and improves fullness. It is especially important during fat loss or when meals are less frequent.
Yes. You need enough daily calories, solid protein intake, progressive training, and a meal schedule that supports recovery inside your eating window.
Not always. Some people keep calories stable. Others use slightly higher calories on training days and lower calories on rest days.
No. OMAD can be hard for many people. Meeting protein, fiber, and energy needs in one meal may feel difficult or uncomfortable.
Hydration and fiber support digestion, appetite control, and routine. They also improve meal quality during shorter eating windows.
Yes. After calculation, you can download a CSV summary and a printable PDF report for planning or record keeping.
