I've been on the paleo lifestyle with cross fit and weight training now since July. I stay strict to the lifestyle as the benefits outweigh everything, plus I do notice my performance is better the stricter I am with it.
My question is when will the body stop losing weight and become more stable with my weight?
Currently I am averaging 2-4 pounds a week weight loss, which I'm ok with cause I still need to trim down, it just feels like I'm melting away with constant weight loss.
My lean body mass has stayed consistent through this process.
Seconded (@Chuck). I believe--just from my own observations--that as we lose more and more weight, our weight loss becomes logarithmic-- that is, that we continue to lose weight at a decreasing rate until we hit the 'ideal' weight for us. Which is why we so often hear about 'those stubborn last few pounds.' This is especially true (I think) if we consistently eat the same caloric load with the same macronutrient ratios. There is a basal metabolic rate that matches every caloric intake, so that each body size (coupled with activity level) requires its own caloric intake to maintain a steady weight. For example: say a 110 lb body at a moderate activity level requires 1800 cals/day to maintain a steady weight. If I weight 130 pounds and am eating 1800 cals/day, I can lose weight pretty quickly. But if I weight 114 pounds and am eating 1800 cals/day, I'll lose weight more slowly. And If I weight 110 lbs, then I won't (in theory) lose weight at all. This idea comes from my days of practicing conventional wisdom, however, so I'm not 100 percent positive it holds. Maintaining the same macronutrient ratios, I think, is key. I think that we all have different equilibriums--different 'ideal' levels--too, but you'll find yours just like everyone else does. And if you find that you continue to lose weight lower than you want to, just increase your calories! Which (for me) has been the most fun step of all!
Don't be as concerned about your weight. If your lean muscle mass isn't shifting, pay attention to you Body Fat %. Unless you are below 10%, live and love life, man. Your body is going down to where it needs to be.
Hehe, you sound like my Mom. She had never been on a diet where she could lose weight without being hungry, until she went on paleo. And it freaked her out a bit. For the first time in her life, she was worried she would get too skinny! I told her for most people, your weight loss will naturally slow and then stabilize at a natural healthy setpoint based on you unique genetics. For some people, the weight loss stops earlier than they would like. For those people they will need to experiment, perhaps exercising more and cutting carbs and or high calorie foods, etc. Or they can just accept where they landed. For those few people who may end up losing more than they wanted, they may need to increase carb consumption, if they end up at their desired weight but are still losing weight. Losing too much weight does not seem to be a super common problem though, especially for those who are pudgy to start with.
