Yes, I have struggled with "Perfectionist" mindset in weight loss and many other things. For years I have thought of myself as a perfectionist that has failed.
Outside of weight loss, I finally looked around and saw less than perfection work being rewarded. At work I could get so bogged down in a project trying to make everything perfect. Then I would see someone get rewarded who worked fast but, to me, did a sloppy job. I started telling myself that OK but fast was good enough. Now, when I have a project I just have to keep reminding myself that OK is better than taking too long to finish or giving up.
The same applies to my eating plan. I have to tell myself that it is OK if I eat 1300 calories instead of 1200 calories. Or that I have not blown my entire plan if I eat 60 net carbs one day. For me, I just have to remind myself that it is OK not to be perfect.
Ask yourself what you would say to a friend. We tend to be kinder to others than to ourselves.
