The Claim

Blood flow restriction resistance exercise results in a statistically significant reduction in subcutaneous fat thickness around the thigh in untrained young males after 8 weeks, whereas high-load resistance exercise does not produce a statistically significant reduction in the same outcome.

Cause and effect
1 study reviewed
In plain English

In untrained young males, 8 weeks of blood flow restriction resistance exercise reduces subcutaneous fat thickness around the thigh, while high-load resistance exercise does not reduce it.

See the scientific wording

Blood flow restriction resistance exercise leads to a statistically significant reduction in subcutaneous fat thickness around the thigh in untrained young males after 8 weeks, while high-load resistance exercise does not, suggesting a potential differential effect on local adipose tissue metabolism.

Why this might work

When blood flow is restricted during exercise, the muscle uses up oxygen faster than it can be replaced, forcing the body to burn fat for energy. This causes fat cells around the thigh to shrink because their stored fat is pulled into the bloodstream and burned for fuel.

    Men who lifted light weights with their legs squeezed to limit blood flow lost a little fat around their thighs, while men who lifted heavy weights didn’t — even though both groups got stronger and their muscles grew the same amount.
