@tekkie3, I can relate to feeling powerless in regards to my weight. It's only been the last year or so that I finally found something that really works and is not really too hard to do once you get started. I struggled with weight through most of my adult life and was always labeled as having prediabetes. A little over a year ago I started into intermittent fasting and now am trying to add low carb healthy fat into my lifestyle which will help me reach my new goal weight of 200. At my high point 20+ years ago I was 330 which is when I got serious and knew I had to make some changes. I joined Weight Watchers for a few years and got down to 250 but still needed to get down to 220 or less. I quit WW because I felt it was a crutch for me. I decided that I had to change my lifestyle and make up my mind to do what I needed to be done. So I spent up until last year going back and forth between 250 and 280 not making any progress until I found out about intermittent fasting. That got me to 220 and gave me the confidence to make a new goal of 200 lbs. That has been more difficult than I thought but I think the reason is too many carbs which led me to the low carb health fat eating plan in addition to the intermittent fasting.

I'm sure it will work for you too. If you want to learn more about it, here is a discussion to get you started.
