Hi doctor,

I am currently on a low carb, high-fat diet to lose weight. How much of a calorie deficit do I need to accomplish weight loss, decrease body fat percentage more than muscle mass?

Welcome to icliniq.com.

Your BMI is 23 which is near normal, it might be with muscle mass or fat content. I need to evaluate still and need details for proper nutritional assessment to provide a correct advice. According to WHO (world health organization), you need 2000 kcal /day.

For most people, a calorie deficit of 500 calories per day is sufficient for weight loss and unlikely to significantly affect your hunger or energy levels. To create this calorie deficit, you need to know what your maintenance calories are.

Thank you doctor,

Should I have a lower BMI? I have 23% body fat currently. My goal is 18-20%. Will 500 calories deficit affect muscle mass more or accelerate fat loss more?

I use a Fitbit tracker to track my daily calorie burn. Should I just minus 500 calories each day from that tracked total?
