I have a goal and need to reach it (or get very close to it) by september, I want to lower my body fat percentage, but I need to gain muscle and strength. Given my deadline I don’t have time to cut and bulk. So can I do calorie cycling to get that done?
For muscle recovery, you need protein (a little over 1.6 g/kg of body weight). You need energy to pump iron. A calorie deficit (especially carbohydrates) will reduce the effectiveness of training. Different macros on different days is not the most stable idea. Pick the minimum level of carbohydrates for pumping.
