Daily Calorie Calculator (TDEE)

How this is calculated

Resting energy use is estimated with the Mifflin-St Jeor equation, the one most dietetic practice uses:

• Male: (10 × weight kg) + (6.25 × height cm) − (5 × age) + 5
• Female: (10 × weight kg) + (6.25 × height cm) − (5 × age) − 161

That figure is then multiplied by an activity factor to estimate total daily energy expenditure. A deficit of roughly 500 calories a day corresponds to about half a kilogram of weight loss per week.

What this has to do with your liver

Gradual weight loss is the intervention with the most consistent evidence in metabolic fatty liver disease, and a calorie deficit is how that happens. But the composition matters too: added sugar — fructose in particular — and ultra-processed food are repeatedly implicated in liver fat independently of total calories.

Every equation of this kind is an estimate with meaningful error in either direction. Treat the number as a starting point, then adjust based on what actually happens over a few weeks. If you have diabetes, kidney disease, or are pregnant or breastfeeding, get a dietitian's input rather than setting a deficit from a calculator.
