Yes. In fact, increasing your physical activities may help you achieve ketosis since your body will deplete your glycogen stores (excess glucose). Engaging in physical activities also help you burn fats, build muscles and/or enhance endurance, not to mention improve your health, mood and overall well-being. There are different ways you can manage your exercise regimen. One way is to pair intermittent fasting with high-intensity interval training (HIIT). Engaging in HIIT at the end of your fasting period is known to be an effective strategy to lose weight. Alternatively, you can consider maintaining a regular low-intensity exercise regimen, such as walking, swimming, etc.
