Question 1

How many calories should a man eat per day?

Accepted Answer

Most adult men maintain their weight between 2,000 and 3,000 calories a day. A sedentary man in his 50s often needs around 2,000–2,200, while an active younger man can need 2,800–3,200. The exact number depends on your height, weight, age and how much you move — the calculator above gives you a personal figure rather than a guess.

Question 2

What is the lowest safe calorie target for men?

Accepted Answer

1,500 calories a day is the usual floor for adult men, compared with 1,200 for women. If the calculator marks your fat-loss target as below the safe minimum, the deficit is too aggressive: add activity or extend your timeline instead of cutting further.

Question 3

How many calories for muscle gain?

Accepted Answer

Add 250–500 calories to your TDEE. A 250 kcal surplus supports roughly 0.5 lb of gain per week with less fat, while 500 kcal is faster but tends to add more fat. Keep protein near 0.8–1 g per lb of bodyweight and train hard, otherwise the surplus mostly becomes stored fat.

Question 4

Why is men's TDEE higher than women's?

Accepted Answer

The Mifflin-St Jeor equation adds +5 for men and subtracts 161 for women, so at identical height, weight and age a man's BMR is about 166 kcal higher. The reason is body composition: men carry more skeletal muscle, which burns more energy at rest than fat tissue does.

Question 5

Does protein intake change my TDEE?

Accepted Answer

Slightly. Digesting food burns calories, and protein costs the most to process — roughly 20–30% of its energy, versus 5–10% for carbs and 0–3% for fat. Eating more protein raises daily expenditure a little and helps you keep muscle while losing fat, which is why the macro split here puts protein first.

Question 6

I lift weights daily — which activity level should I pick?

Accepted Answer

If you train hard 6–7 days a week and spend the rest of the day sitting, choose "Very active" (1.725). Reserve "Extra active" (1.9) for physical jobs plus daily training, or for two-a-day sessions. Picking a level that is too high is the most common reason a calorie target stops working.
