Thanks to all for your suggestions! I would like to follow up with some data and questions. I am not a smoker, excessive drinker, or drug user. Most of my weight gain has been in fact in the form of muscle, no doubt, however, I have reason to think that fat has gone up too. It is difficult to gain muscle mass without loading a little fat in your diet, so I think I have increased both since I lost weight a long time ago. To give you some numbers, I have gained 50 pounds since a few years back - most of this is muscle, don't worry, but I suspect some of it is fat as well. I do occassionally overtrain myself unintentionally, but I don't think it is related to the problem of low HDL/pre- Diabetes patterns. My triglycerides are around 80 and my HDL is around 25 to give you some benchmarks, so as you can see, I'm bouncing around a ratio of 3. Re: Niacin - what are people's opinions of Niacinamide or whatever the "flush-free niacin" is - is it worth the money? Will it have a noticible impact or should I just just jog more? Re: Diet - what are examples of foods that are high in protein but low in carbs and fat? I need a high volume of protein to support my weight training, but it seems like most meat, nut, and cheese products are inevitiably bundled with fat & carbs - any ideas on good protein only foods? Really appreciate the help.
