Calorie

calculator.
Mifflin-St Jeor, the formula most evidence-based coaches use. Plug in your numbers, get a starting point, and read the bit underneath about what to do with it. No email gate.
Hit these averages across a week — don't worry about nailing every day. If progress stalls for two weeks straight, drop calories by 100-150 and reassess. The number is a starting point, not gospel.

What to actually do with the number.
/ It's a starting point
The maths is good, but it's a population average. Your real maintenance is whatever you eat across two weeks while your weight holds steady. Use the number, then adjust.
/ Average it across a week
Daily calories vary. Some days are higher, some lower. What matters is the seven-day average — chase that, not perfection at every meal.
/ Stalled? Don't crash
If progress flattens for two weeks, drop calories by 100-150 and add 1000-2000 steps. Slash-and-burn cuts cost you muscle and make rebound likely.
/ Protein is the lever
If you only get one macro right, get protein. The number we suggested is around 2.2g per kg of body weight — enough to hold muscle in a deficit.
/ Hunger isn't a sign you're winning
Aggressive deficits feel productive but rarely stick. A 300-500 kcal deficit is plenty for most. Slower is more sustainable, and the scale tells the truth eventually.
/ Track your training too
Calories without progressive overload is just dieting. The training stimulus is what makes the food count for muscle, not just weight loss.
