Dieting for 35 years

To me the best "diet" is one that you can maintain long term. Are you on a calorie tracking app/website? I use My Fitness Pal. It seems to have the best database of foods and is the easiest to add your own recipes to, in my opinion. Knowledge is power. Sometimes just seeing the in and out can do the trick. It's definitely eye opening. Some people have been amazed that I lost 40 pounds without giving up anything. What I did instead was to invest in a digital kitchen scale and a couple sets of measuring cups and spoons. Then, I weighed/measured and tracked everything. If I wanted chips for a snack, I'd check to see if I had the extra calories for the day (I try to put in the three big meals in the morning to help plan room for the cravings). If I did, I'd measure out some. Sometimes just seeing how many calories I had left convinced me to skip the chips, sometimes not. If I didn't have the extra calories, I'd either chose a different snack or go work out. You can do this. Measure and track everything. Prepackage snacks that are good for you AND that you LIKE to help you choose those over the junk. Make sensible choices that limit but don't eliminate what you really want. You can do this.
