Fat is not the enemy.
About this calculator
Fat is not the enemy. Your body needs it for hormones, vitamin absorption (A, D, E, K), cell membranes, and steady energy. The question is how many grams fit your calorie budget and goal.
This calculator turns a daily calorie target and fat percentage into grams. Fat has 9 kcal per gram. At 2,000 kcal and 30% fat, you get 600 kcal from fat — about 67 g per day. Split across four meals, that is roughly 17 g per meal (a tablespoon of oil is about 14 g).
Fat loss plans often sit at 20–30% fat while keeping protein high. Maintenance and muscle gain often use 25–35%. Very low-fat diets below 20% can work short term but may affect hormones if protein and carbs do not compensate.
Get your calorie target from the [[tdee]] or [[calorie]] calculator first. Use the [[macro]] calculator for a full protein-carb-fat split, the [[protein]] calculator to lock protein, and the [[carbohydrate]] calculator for carb grams. The [[bmi]] calculator gives weight context for setting calories.

Frequently asked questions
How many grams of fat should I eat per day?
Most adults land between 45–90 g/day depending on calories. At 2,000 kcal with 30% fat you get about 67 g. Athletes on higher calories may need more; low-calorie cuts may use less.
Why use 9 kcal per gram for fat?
Nutrition science uses 9 kcal/g for fat, 4 kcal/g for protein and carbohydrates. Food labels and macro calculators use these averages for meal planning.
Is 30% fat too much for weight loss?
Not necessarily. Total calories and adequate protein matter more. Many successful fat-loss diets use 25–30% fat. Drop fat only if it helps you hit protein and stay in a deficit.
How do I count fat in Indian cooking?
One teaspoon ghee or oil is about 5 g fat. One tablespoon is about 14 g. Count tempering oil, salad dressings, nuts, paneer, and whole milk — they add up quickly.
Should I eat less fat at night?
Daily totals matter more than meal timing for body composition. Some people digest lighter dinners better; others sleep fine with fat at night. Match the pattern to your digestion and training schedule.
