How long have you been eating and training this way, and how much weight did you gain? If you just started and gained 2 lbs, it could easily be that your calories are low enough and you just gained incidental weight, like from the mass of food (depending on what you used to eat and currently eat) or extra water. If you have been dieting/training for a few months and gained 20 lbs, obviously something very different must be going on. Whether your metabolism may be slowing down and such is not discernible from your post, so more information may help people give useful suggestions.
why is it a nice problem? it's hard to lose weight because theni have to eat so little!
btw i like to do fasted cardio on my tredmill in the morning. how fast should i put it on? i never know how to decide what is "slow-moderate" pace. but yeah gaining muscle/weight has never been a problem for me. i've always had a muscular build (all genetics) and been very strong.
i'm just having difficulty getting below 10% body fat. i'm aware that it's 90% diet/cardio but it's just frustrating when i'm being extremely strict on my diets and have very intense workouts and not losing any weight.
5'10 205 @ 14% body fat? Are you sure the body fat calculation is correct? I don't mean to be a skeptic, but that would make you pretty damn strong. Anyone that strong should be losing weight at 2500 calories a day one would think. Something doesn't add up.
