There is plenty of advice when it comes to fitness. The ones that fills most pages are the articles on telling you what to eat and what not to eat. I found this contradiction just after the second click. Notice the article id on filling foods to lose weight and below is another video link to tell you how bad the same food is for losing weight.
The old-school rule will and always work...moderation. Just take notice of what you eat and when you eat. There is no one that knows what you eat except you. To be honest you know when you are over eating or eating something that you shouldn't. If that doesn't work try writing down every single thing you put into your mouth to eat every day for at east three weeks. After that you will have lost started good habits or for some run out of paper. If you run out of paper please consult help from a professional.
