I'm personally convinced that the problem is not effort or motivation.I can tell you that the Diet industry incorporates certain foods in their diet plan that are actually not diet foods at all. The diet industry is big business, and unfortunately many companies market their products as healthy, even though they are counter-productive options. And I don't even want to start about the food and sugar lobby.
I can't state this enough: SUGAR IS THE NUMBER ONE PROBLEM !
Let me give you 3 examples of diet foods that actually make you fat:
1. Fruit Flavored Yogurts

These are in reality pint-sized sugard bombs, while their reputation as a go-to diet food has regrettably evolved. Next time you’re picking out your favorite yogurt, double check the sugar content. You might be surprised to find there are 15+ grams of sugar per serving. Of course you can purchase the sugar-free varieties, but then you’ll be consuming unwanted artificial sweeteners, which can be just as bad for you. Instead, opt for plain Greek yogurt. Flavor it yourself by adding a handful of fresh berries.
2. Fat-Free Products

3. Protein Bars
Another beauty to be be wary of is the protein bar, despite its prevalence in many diet programs and meal plans. These may seem like a great option because they contain protein, but once again you have to look a little closer.
Check that sugar content. Most protein bars have upwards of 15 grams of sugar per bar. Some contain 30 and even 40 grams. In actuality, these are glorified chocolate bars. While you can buy a few bars with very low sugar content (five grams or less per bar), these will require a little searching.
