The Claim

Consumption of resistant starch type 2 increases fat oxidation by 32% and decreases carbohydrate oxidation by 18% in healthy young adults compared to digestible starch, without altering total daily energy expenditure or protein oxidation.

In plain English

When healthy young adults consume resistant starch type 2 instead of digestible starch, their bodies burn more fat and less carbohydrates, but total daily energy use and protein burning remain unchanged.

See the scientific wording

Consumption of resistant starch type 2 increases fat oxidation by 32% and decreases carbohydrate oxidation by 18% in healthy young adults compared to digestible starch, without altering total daily energy expenditure or protein oxidation.

Why this might work

When resistant starch reaches the colon, gut bacteria break it down into short-chain fatty acids. These fatty acids travel to the liver and fat cells, where they reduce the production of energy molecules from sugar and increase the use of fat for energy. This causes the body to burn more fat and less sugar without changing total calorie use.

  1. Study: The In Vivo Net Energy Content of Resistant Starch and Its Effect on Macronutrient Oxidation in Healthy Adults

    When people ate resistant starch instead of regular starch, their bodies burned more fat and less sugar for energy, but didn’t burn more total calories — just like the claim says.
