I've yo yo dieted my entire life. I'm 5'1 and recently weighed 230, now down to 223. I started out most recently low carb, after a long stretch on the anti diet bandwagon. I've read a lot about keto and am ready to commit to some changes. I've been low carb for a couple of weeks, but only just decided to go all the way to keto over the last few days.

I've set my carb goal to stay below 20 grams. Does that seem right? I'm keeping my calories below 1800. I'm walking a mile to a mile and a half each day. Every other day I do a 10 minute beginners yoga routine or a 20 minute seated strength training routine. Does all of this sound like I'm on track?

I'm concerned about the possibility of having a lot of loose skin if I go into ketosis and lose weight quickly.

Another concern. With some special events coming up I know I will eventually treat myself, probably to a slice of pumpkin pie. From what I've read, this is not the end of the world,and I should be able to go back into ketosis again as long as Im not eating pumpkin pie every day.

My goal is to lose 100 pounds. Initially I wanted to lose a pounds a week, but I understand with this diet, it could go much faster. My mini goals are to work my way down through the obesity categories, to overweight, to finally normal bmi.

Overall I think I am doing well. I like what I'm eating and don't feel tempted to cheat, (aside from probably at Thanksgiving when I don't intend to go overboard). I guess I just want some reassurance that what I'm doing is right (particularly the 20gram carb cap) and maybe get some advice from anyone who has been doing this with success.
