First of all,
A lot of people have found the support they need on this site. There are inspirational successes as well as folks struggling to get started on their journey to better health.
I had trouble starting a diet -- I found it easier to start by making positive changes that didn't involve calorie restriction. So I started by just taking supplements regularly, which is something I should do anyway, but is particularly important if on a diet. Then I began to drink more calorie-free fluids (many folks believe in water-only, but I do Crystal Light). Then started the habit of adding a salad or low calorie soup with most meals.
It's easier for me once I have gotten into a few healthy habits first, and I feel I have made some progress, even if the scale hasn't budged.
