Alright, for about 12 weeks I was doing a solid cut. Counting cals, doing cardio, weight training, etc. Only supps I used was whey protein, because protein. For the first 6 weeks I had my calories at 1900-2000 and for the second 6 weeks I dropped it to 1600-1800 calories. I went from 160 to 144 in those 12 weeks. Not bad.
Well, as of 5/31 I began my first real bulk. And I've eased into it. Only supps I've added thus far are a multivitamin and crea mono. Nothing real amazing. Tomorrow I'm adding in Condense and D-Pol for my pre-w/o. 1 scoop of each mixed together. Anyway, calorie wise I've bumped it to 2600-2800 a day for the most part (some days I've hit 3200 when I eat out). Despite adding in the calories, near double at that, I seem to have reduced some body fat, particularly in my gut and lower back. Not complaining, since my lifts have all improved remarkably. Went from 225x1 on bench to 215x6 (not the same, but with the math, it's a decent increase).
What I'm getting at here is, why in the world have I seemingly reduced my bodyfat (not tested, just in the mirror), when I've nearly doubled my calories? Yes, my training has been much more intense and much more planned out and methodical (Wendler's 5/3/1 with periodization accessory) and I've gained some strength. Haven't noted any size gains yet, and I measure 2x a month.
If anyone can give me a biological/physiological/nutritional explanation, that would be awesome, as I enjoy learning as much as possible. I have a feeling though that while I was eating such few calories my metabolism slowed down drastically and was preventing my body from utilizing fat stores vs available glycogen due to survival mechanisms. That's just my hunch from what I've read in a few physiology textbooks and nutrition textbooks.
Long post, I know, but I'm detail oriented and tried to include as much as possible that could help. Thanks in advance y'all.
