The Claim

A protein-sparing modified fast (1.2–1.4 g protein/kg ideal body weight) in obese adults with type 2 diabetes is associated with reduced serum glucose and insulin concentrations and increased free fatty acid and ketone body levels, with ketonuria appearing within 24–72 hours.

In plain English

In obese adults with type 2 diabetes, a specific low-calorie, high-protein diet leads to lower blood sugar and insulin levels, higher levels of free fatty acids and ketone bodies, and the presence of ketones in urine within 24 to 72 hours.

Why this might work

When calories are cut but protein intake stays high enough, the body runs out of stored sugar and starts burning fat for energy. The liver turns fat into ketones, which the brain and muscles use instead of sugar. This lowers the need for insulin, so the pancreas makes less of it. At the same time, the protein intake keeps muscles from breaking down by keeping protein building active and breakdown quiet.

  1. Study: Nitrogen Metabolism and Insulin Requirements in Obese Diabetic Adults on a Protein-Sparing Modified Fast

    This diet, which gives just enough protein to keep muscles from breaking down while cutting most calories, made blood sugar and insulin drop, while fat breakdown and ketones in the urine went up — all within a few days. It worked exactly as the claim said.
