Scientists thought your body mostly burns fat at rest and during easy exercise, but new measurements show your body actually burns a lot of carbohydrate too - around 40-60% of the energy you use.

Low carbohydrate high fat ketogenic diets on the exercise crossover point and glucose homeostasis

Narrative Review

2023

The study shows that when athletes adapt to a low-carb high-fat diet, their bodies can burn much more fat even during intense exercise - contrary to what the traditional 'crossover' model predicted. This challenges the old idea that our bodies must switch to mainly burning carbohydrates during exercise.

When people switch to a low-carb, high-fat diet, their bodies can burn fat for energy during harder workouts that would normally require carbs, whereas on a normal diet this switch happens at easier exercise intensities.

When doing a high-intensity workout on a hydraulic machine, your body burns more sugar (carbs) for energy than when you lift weights, run, or bike at the same time.
