Daily Protein Intake Calculator

Calculates how many grams of protein to eat per day based on your body weight and how active you are. It scales recognised grams-per-kilogram guidelines so you get a target suited to sedentary living, general fitness, or serious strength and endurance training.

Calorie Deficit Calculator

Find the daily calorie target you need to hit to lose weight at a chosen pace — the operational number that turns "I want to lose 5 kg" into "eat 1,950 kcal a day starting Monday." Enter your TDEE (maintenance calories) and the rate at which you want to lose weight, and the calculator returns the daily intake target along with a projected timeline.
