I'm new to this site. I hope it'll help me stay on track. In my 20's I was in great shape and eating very healthy. In my 30's, 3 kids put my weight at around 30 pounds extra. I'm coming up on my 40th birthday this summer and I would really like to lose 20 pounds. I do well for a while..... and then I slip. I know yo-yo dieting isn't good and it's a set up for weight gain. So I would really like to get a grip of the weight now because I know it only gets harder as you age. I want the muscle tone back too.
