I'm still new to all of this working out and everything, as I've only been doing it since about January. Back in November of last year, I lost 15lbs in a week due to Mono, and since then I've regained nothing back. The thing is, since I lost all that weight so fast, I had a lot of 'extra skin.' I'm 5'11 and weigh about 165 depending on the time of day. When I held out that body fat percentage machine thing, it said I was at 13%. That's my pic in AV. Well, I want to get under 10%, but I feel like I'm not eating the right foods, or just not doing enough cardio. I have an older friend of mine who was at about 340 lbs, and his trainer put him on an extremely strict diet of just lean protein and greens, and that's it. I think the idea was no carbs and no sugar, but that's all he could eat. What I'm wondering is if that would work for me. He told me that if I did that for just one month, that I'd notice a huge difference. I also think that besides just the eating, I'm going to start swimming every day for about forty five minutes. As far as muscle mass, I would love to get my arms bigger and also my chest. My legs are naturally big and I just want to tone them up, not get bigger. I'm thinking that the swimming will do what I want to my legs. I'm also wondering if with the chicken and green bean diet, if there are any protein shakes that I can drink that wouldn't go against that diet. A shake with very little to no sugars and no carbs, obviously. I'm also wondering if because I have some loose skin, if I should work out to get bigger, if that makes sense. My thought process is that if I get bigger, it'll tighten up the skin. Any help would be great!
