The Claim

In severely obese adolescents undergoing a medically supervised protein-sparing modified fast, improvements in total cholesterol and high-density lipoprotein levels were observed, but these changes were not statistically significant due to small sample size and high dropout rate.

Description
1 study reviewed
In plain English

In severely obese adolescents following a medically supervised protein-sparing modified fast, total cholesterol and high-density lipoprotein levels changed, but the changes were not large enough to be considered reliable due to few participants and many dropping out.

Why this might work

When the body runs out of carbs and fats to burn, it starts breaking down stored fat for energy, producing ketones. This shifts how the liver handles cholesterol and fats, reducing the amount of bad cholesterol released into the blood and increasing the amount of good cholesterol that helps remove fat from arteries.

  1. Study: The Protein-Sparing Modified Fast Diet

    In a small group of very overweight teens on a strict high-protein diet, their 'good' and 'bad' cholesterol levels got a little better, but the group was too small and some dropped out, so scientists couldn’t be sure it wasn’t just luck.
