The Claim

In healthy young adults, a 54-hour high-protein (30% energy), lower-carbohydrate (29% energy) ultra-processed diet reduces net positive energy balance from 32% to 18% compared to a normal-protein, normal-carbohydrate ultra-processed diet, indicating a favorable shift in energy partitioning.

Cause and effect
1 study reviewed
In plain English

In healthy young adults, eating a diet high in protein and low in carbohydrates for 54 hours reduces the excess energy stored in the body from 32% to 18% compared to a diet with normal protein and carbohydrate levels.

See the scientific wording

In healthy young adults, a short-term (54-hour) high-protein (30% energy), lower-carbohydrate (29% energy) ultra-processed diet improves energy balance by reducing net positive energy balance from 32% to 18% compared to a normal-protein, normal-carbohydrate ultra-processed diet, indicating a favorable shift in energy partitioning.

Why this might work

Eating more protein and less carbohydrate makes you feel full faster and burn more calories as heat. This happens because protein triggers hormones that tell your brain to stop eating, slows down how fast you eat, and forces your liver to work harder to process the protein, which uses up extra energy. As a result, your body stores less fat even when you eat more than you need.

  1. Study: Short-term effects of high-protein, lower-carbohydrate ultra-processed foods on human energy balance

    Even though people still ate more calories than they burned, eating a high-protein, low-carb ultra-processed diet made them eat fewer calories and burn more, so they gained less fat than when eating a normal-protein ultra-processed diet.
