In plain English

Consuming resistant starch type 2 does not change the total number of calories the body burns in a day.

See the scientific wording

Resistant starch type 2 does not increase total daily energy expenditure in healthy adults, indicating it is unlikely to promote weight loss through increased calorie burning.

Why this might work

Resistant starch reaches the colon undigested, where gut bacteria break it down into short-chain fatty acids. These fatty acids signal the liver to reduce sugar-based energy production and increase fat burning. Fat cells also take up less sugar and make less fat, further pushing the body to burn fat instead of sugar. This shift in fuel use does not change the total number of calories burned in a day.

    Eating resistant starch doesn’t make your body burn more total calories in a day, even though it changes whether your body burns more fat or carbs. So it won’t help you lose weight by speeding up your metabolism.
