Hello, I've been doing the body for life training program for 6 weeks now. I've gained about 6 to 7 pounds of muscle total and lost 2 pounds of fat. I only started to loose fat when I started the Zone 3 weeks ago. My question is, how do I know when I've gained enough muscle? I don't want to get huge, just look toned and healthy. Will my musle gain slow down soon, or should I do less weights? How do I do this? Should I substitute the weights for cardio. When I do more cardio, I get really hungry sometimes and have to eat an extra block or two. This slows my weight loss. The other question I have is about calories. I eat 12 to 13 blocks currently. When I get to my goal weight, won't my body be adjusted to burning only that many calories? I thought that normal active women burn around 2000 calories a day. I'm losing weight slowly, so my metabolism must be slow already. If when I reach my goal weight I keep losing weight, I will have to eat more fat. Then I will be eating about an extra 800 calories from fat. I seems to make more sense just to add a couple of blocks. Also, when you reach your goal, you are only supposed to add monosaturated fat. That means, I'll be eating alot of olive oil and avacados! Sorry for so many questions, it's just confusing. I just can't wrap my head around the idea of eating 1200 calories a day for the rest of my life. Or am I way off here. The way I figure is that when you restrict your calories, your metabolism slows to adjust to that level. That's why people plateau. Is there something wrong with this picture?
