It is the same for me. The set point sticks really hard. 2x a week interval training plus lifting plus eating chicken until my skin crawled did nothing for me. I know it's horrible to hear, but what has helped me a lot was the other night on TV they talked about a long-term study they did with Leisure World residents that showed that being thinner didn't correlate to a longer life, and in fact for women, being a little heavy led to the longest life with the best health in late life. So okay, I can deal with that. Also, recently I figured out that I have some food allergies and some foods give me really bad gas so cutting down/out on these foods took some of the puffiness away, which is not a huge shrinkage but it's something I can see and feel.
