Does exercise reduce resting metabolic rate?

Several lines of evidence suggest exercise may modulate resting metabolic rate. Bed rest in sedentary individuals leads to a reduction in resting metabolic rate. Similarly, in highly trained runners, cessation of daily exercise training lowers resting metabolic rate by about 7 to 10%.

Should you ever eat below your BMR?

To prevent your weight loss diet from affecting your metabolism, make sure that you never eat fewer calories than are required to sustain your BMR. Slightly increasing your protein intake and adding resistance exercises to your workout routine may also help ( 14 , 15 ).

What hormone increases metabolic rate?

What organ determines metabolism?

Liver. The metabolic activities of the liver are essential for providing fuel to the brain, muscle, and other peripheral organs. Indeed, the liver, which can be from 2% to 4% of body weight, is an organism’s metabolic hub (Figure 30.14).

What can speed up metabolic reactions?

Enzymes are protein catalysts that speed biochemical reactions by facilitating the molecular rearrangements that support cell function. Recall that chemical reactions convert substrates into products, often by attaching chemical groups to or breaking off chemical groups from the substrates.
