I'm certain that many of you are aware of this and I'm also certain that there is a version here on the site that I haven't seen yet. But, as I'm a busy body, I thought I'd pass this on for your parusal.
Obviously, the goal for many of us here is to lose weight in a healthy way. One of the issues that often happens, is people cut down portion sizes but don't change the foods. That can mean that people are not getting the right vitamins and nutrients and can suffer as a result. When I became vegan, I was told about a website called Cronometer. It is an American site so you do on occasion need to approximate but it gives a very substantial breakdown of all the nutrients and vitamins that are in a food. You fill it out like a diary and it adds to the breakdown as you go along. It's very useful because you can see what your eating and what is missing. Better yet, it's free.
Even if you don't use it regularly, it's good to duck in every now and then just to have a look and check what your eating.
