Got questions? We have answers.

Can intermittent fasting help me lose weight?

Yes! Fasting alters how often you eat, which helps you eat less without counting calories or going on a diet. Intermittent fasting also encourages healthier, more conscientious choices around what you eat. Finally, intermittent fasting enables your body to tap into its fat stores for fuel so that you burn fat faster.
