I'm 26, male, and have been active my whole life. I am a personal trainer and love working out. I am a mixture of natural bodybuilder and strength athlete.

I usually maintain a body fat level of about 8-10% most of the year, at a bodyweight of 210-220. If I do decide to bulk, which I have not done in a few years, I will allow myself to creep up to 12%. I have never truly tried to trim down to about 6% body fat, but I am currently on the road to doing so. I am on day 2 of a 15 day cut, with cardio twice daily, weights 6 days per week, and a diet with calories in the 2,500-3,000 range, 45% carbs, 35% protein, and 20% fat. I find that I need the carbs to stay a bit higher, because if I don't have them I flatten out and lose energy.

I'm guessing my daily output from the cardio and the weights adds up to at least 1,500 calories burned from exercise, and adding my RMR into the equation, I create a pretty big deficit for myself, which is what needs to be done to try to get down to that kind of body fat.

I am doing this because I'm going on vacation and one of my friends wants to be leaner than me, which is not happening haha.
