Study: Exercising at the start of fast can he Study: Exercising at the start of fast can help people reach ketosis 3.5 hours faster Fasting is gaining in popularity as a means to lose weight; pairing it with exercise can boost health outcomes For the study, the researchers asked 20 healthy adults to complete two 36-hour fasts while staying hydrated. Each fast began after a standardized meal, the first fast starting without exercise and the other with a challenging treadmill workout. Every two hours while awake, the subjects completed hunger and mood assessments and recorded their levels of B-hydroxybutyrate (BHB), a ketone-like chemical. Exercise made a big difference: when participants exercised, they reached ketosis on average three and a half hours earlier in the fast and produced 43% more BHB. The theory is that the initial exercise burns through a substantial amount of the body’s glucose, prompting a quicker transition to ketosis. Without exercise, the participants hit ketosis
