I'm fine with that level of loss. I feel better and at 178, look better. I'd rather be 150 in a year than be 150 in January but only able to eat say, VLC or not eating fruit or never having wine.I'm not being snotty here, but for those that think very overweight people can easily accept a one to two pound per month loss, I invite you to become a 200 pound woman in our culture for awhile. Once you get in the mindset to get healthy, it can be frustrating to see such small results. My own weight loss slowed to a crawl in the 140s. I can accept that because for the most part that's a fairly acceptable weight, but if I'd only lost one or two pounds per month in the 180s or 170s, I probably would have questioned PB, or at the very least tweaked it. Or tried a hack. As it is, I pretty much combine PB with a reduced calorie approach.
And it's a number- In mid October I was 177 and my size 12's were kind of snug. Today I am 179 and my 12's are getting loose. Cross Fit!
For me, sustainability is key.... and if you say "I used to do Primal, but it sucked because it was nothing but meat and veggies".... well, it wasn't Primal you were doing. You were doing something else.
Primal as written leads to healthy weight loss for most people and it is good. I always hate reading posts from newbies who are struggling that include that they don't eat fruit or have been in ketosis... I feel like they haven't been able to experience the benefits.
Anyhow, eat well- eat that whole list, move, sleep, enjoy life. If you aren't losing, eat a little less of the list, double check your 20%, change up your workout.
