you see, you don't understand that the fat tissue itself holds water is one point - so even when you have zero carbs and you are dehydrated, you will look wet
and the second thing - is the difference between lean 4-6% and ripped 4-6% for example? you are dry as a desert on the day of the competition and you have 220 lbs, after the competition you eat the next day and the next 3 days you are on a diet where you eat more calories or eat a few cheated meals and after these 4 days you have 240 pounds - you think that the weight you caught it fat...?
