I'm actively losing weight but always seem to gain 3-4 lbs following intense exercise days.
I'm losing weight by trying to take in about 2000 or so calories a day. I'm not strictly counting, more like approximating, but things are going well so far. I'm a lot more calorie-aware of what I eat now(check out my last question
Each day, I weight myself first thing in the morning.
Here's what I'm noticing-My weight gradually lowers, or steadies, as the days go on. Then, after days with activity (2+ hour bike rides, 1 hr pickup basketball), my weight creeps up about 4 or so pounds. This is fairly consistent with the day after exercise. Sometimes, on post-exercise-days, I'm a lot hungrier than normal(which I would expect). A few days later, those 4lbs are gone and i'm back on my downward trend(yay!).
Now when I'm riding, I'll drink 2 16oz bottles of cytomax(90 calories per bottle), maybe a clif bar. I eliminated gatorade and 'carbo loading' and huge post-ride meals. When I ride, its at tempo, or a canyon climb-no LSD for me. I'm working at 80-95% MHR for those 2 hrs.
In short, there is no way in hell
that I'm eating an additional 14,000 calories or so in 1 day to put that weight back on. Dont forget that I just burned 3000 or so calories on that bike ride.
I'm pretty sure that those fluctuations are water but I'd love an explanation. Is this normal? This only
happens the day or two after intense exercise.
Also, when does the body actually 'burn' the fat? I know that you need to have a 3500 calorie deficit to burn 1lb fat. When does this take place? Does it happen in real time, or is there some 'batch job' that runs (sorry!) that figures the deficit and lets go of the fat.
