The Claim
In women with obesity, a 1-month very-low-calorie ketogenic diet is associated with a sustained increase in protein oxidation that begins within the first 24 hours and persists throughout the diet, contributing to lean tissue loss.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In women with obesity, following a very-low-calorie ketogenic diet for one month leads to a continuous rise in protein breakdown starting within one day and continuing for the entire month, resulting in loss of lean body tissue.

When carbohydrate intake drops very low, the body runs out of stored sugar and must make new glucose from muscle protein to keep the brain and other essential tissues functioning. This breaks down muscle tissue, releasing amino acids that are turned into glucose. The body keeps doing this every day, so muscle keeps getting lost. At the same time, fat becomes the main fuel source, but the brain still needs glucose, so protein breakdown never stops.
What the research says
1 studyThe study found that when women with obesity followed a very low-calorie keto diet, their bodies started burning more protein for energy right away—and kept doing it for the whole month. This led to a noticeable loss of muscle tissue, which matches the claim.
