how many calories can your body absorb?

Protein takes the most energy to digest (20-30% of total calories in protein eaten go to digesting it). Next is carbohydrates (5-10%) and then fats (0-3%). Thus, if you eat 100 calories from protein, your body uses 20-30 of those calories to digest and absorb the protein. You'd be left with a net 70-80 calories.

As a general rule, people need a minimum of 1,200 calories daily to stay healthy. People who have a strenuous fitness routine or perform many daily activities need more calories.

Digesting and Metabolizing Protein Burns Calories If we go with a thermic effect of 30% for protein, this means that 100 calories of protein only end up as 70 usable calories. Bottom Line: About 20-30% of protein calories are burned while the body is digesting and metabolizing the protein.

After all, weight loss (to oversimplify it) does require burning more calories than you consume. But some weight loss plans suggest men should consume 1,500 to 1,800 calories each day and women should consume 1,200 to 1,500 calories each day to shed pounds safely.

Daily Calories Herzog estimates that, if you're an average person, you need to eat between 1,000 and 1,400 calories per day to run your body doing absolutely nothing. If you move around a little bit, then you need to eat an additional 400 to 600 calories per day.

Using a simple conversion (1000 calories = 1 Calorie, 1 calorie = 4.1868 J), this amounts to 8.37 x 106 joules ingested per day. This means that the average person expends ~8.37 x 106 joules of energy per day, since most of us are in some sort of equilibrium with our surroundings.
