The Claim

A 12-week hypocaloric meal replacement program in obese adults is associated with a significant reduction in fat mass, indicating that weight loss in this context is primarily attributable to loss of adipose tissue.

In plain English

Obese adults who followed a 12-week hypocaloric meal replacement program lost weight primarily through a reduction in body fat.

See the scientific wording

In obese adults, a 12-week hypocaloric meal replacement program was associated with a significant reduction in fat mass, suggesting that weight loss was primarily due to loss of adipose tissue.

Why this might work

When the body gets fewer calories than it needs, it breaks down fat stores for energy. Fat cells release stored fat into the blood, and the liver and muscles burn that fat to make energy, causing the body to lose fat mass.

    People who replaced one meal a day with a nutritional shake lost weight, but their thigh muscles got stronger and thicker, not smaller — meaning they lost mostly fat, not muscle.
