Nutrition & calorie guides

Practical guides with real numbers. No miracle diets, no promises — just what the evidence supports and what actually holds up over months.

How many calories a day to lose weight?

Working out your daily burn, how big a deficit really needs to be, and why a bigger one backfires.

How to calculate your calorie target (TDEE)

The formula, activity multipliers, the mistake nearly everyone makes, and when to recalculate.

How much protein per day do you need?

Amounts by body weight and goal, protein in common foods, and whether powder is necessary.

What are macros and how to split them

Protein, carbs and fat — how much of each, in what order to calculate, with a worked example.
