Their blood ketone levels were 137–314% higher when they exercised before a meal than when they exercised after a meal (20). Keep in mind that although exercise increases ketone production, it may take 1–4 weeks for your body to adapt to using ketones and fatty acids as primary fuels.

Does exercise increase ketosis?

Ramp up your physical activity

A growing number of studies have found that being in ketosis may be beneficial for some types of athletic performance (16, 17 ). In addition, being more active can help you get into ketosis. When you exercise, you deplete your body's glycogen stores.

Are ketones higher after working out?

During the exercise the extra ketone bodies formed also serve as a fuel of respiration and therefore do not accumulate. After cessation of exercise the raised concentration of F.F.A. results in a continued high rate of ketone-body formation which shows itself as post-exercise ketosis.
