Hi,
I have been doing P90X for the past 6 weeks. I love the workouts and am feeling fitter and stronger, and if those are my only benefits I'll still be happy to continue long into the future. The downside is that I haven't lost any weight, inches, or body fat. I think I need to eat more, but I'd love some advice first.
I'm 5'8", 175 lbs, female, 46 years old, body fat is 26-27%. A healthy weight for me when I'm in good shape with around 20-22% body fat is 160-165. I have somewhat more muscle than the average woman (not necessarily more than the average P90Xer

). I currently eat around 1500-1600 calories per day because I gain weight if I eat more than that. I eat very clean, mostly vegan, with macro ratios of approx 40/40/20.
After doing these workouts and using the nutrition guide, I have come to the conclusion that I've probably (unintentionally) been eating too few calories for the past 6-8 years. I think I have probably (and again, unintentionally) caused my metabolism to slow down quite a bit. For the past several years I have probably averaged 1200-1400 calories per day, mostly healthy with some slips, moderate activity level. My weight has gradually crept up about 10 lbs in the past 6-8 years.
So here's my main question: Approximately how long does it take a woman my age to repair her damaged metabolism due to long-time under-eating. I know this can't be answered exactly. I'm just wondering if this is a process where we're talking in terms of weeks, months, years, or never? I'm willing to get past my mental block and eat more, but it'll be easier to do if I have some ballpark idea of how long it might take a long-time slow metabolism like mine to respond and relax and begin to burn the fat.
Any input?
Thanks very much,
Kate
