Question

why do fad diets sometimes result in initial weight loss?

○ eating less protein

○ all of the above

○ loss of fluids

○ increased metabolism

Explanation:

Fad diets often lead to initial weight loss due to loss of fluids. When calorie intake is severely restricted (common in fad diets), glycogen stores are depleted. Glycogen is stored with water, so as glycogen is used up, water is lost. Eating less protein is not a reason for initial weight - loss in fad diets (in fact, some fad diets are high - protein). Increased metabolism is not a typical initial effect of fad diets; often, over time, metabolism can slow down due to calorie restriction.

Answer:

loss of fluids
