- To clarify a good deficit is about eating about 500calories Less than what your BMR(is the amount of calories your body burns just by existing). -look up what your macro nutrient intake should be based off your BMI, frame size, age, gender, and activity level. - DO NOT STARVE YOUR SELF OR EAT LESS THAN 1200 CALORIES A DAY!!!! You body needs the nutrients from the food you eat and if you diet isn’t supplying it then it will use the nutrients from you heart and bones and other organs -
