Sorry to hear, you are having a tough go at it
how much more weight you have to loose? Have you tried exercising & measuring your heart rate when you do?
Stress hormones can keep you from loosing weight as well. Have you tried meditation?
It can be extremely discouraging, I know. I have been dieting my whole life, sense I was 11 years old. And then one day I just ballooned in weight. Gained a huge amount in a short span of a few years. And I been trying to loose since, 10 years now.
You know you can have stuff on LC. With Dr.Bernstein plan he has chocolate souffles, cheesecake, peanut butter pie. There is sugar free pudding. So you can treat yourself.
Right now I choose not to cause I think I pig out on that stuff, at this point I don't trust myself.
I don't know if your female but could you be going through hormonal imbalances? Maybe your period is adjusting could explain the slips.
Are you diabetic? Insulin Resistant? Have high cortisol levels?
Are you drinking diet soda or using a lot of sugar free sweeteners? Sugar free stuff will still impact your insulin levels. So it is best to use those as treats than on a daily basis.
Another thought is you body becomes adjusted. So try and very your carlorie intake. In one day I can eat anywhere from 1300 to 2100. To avoid my body getting used to a particular amount.
