I know there are tons out there - Atkins (do people still do that?), Weight Watchers, low carb, low fat, high-protein, low calorie, Whole30 ... that last one strikes me as really controversial. I understand all of it except for the no legume/soy thing. No peanut butter?!?!? C'mon.
Anyway, my diet is called: the don't be lazy diet. It has 2 rules: Don't be lazy. Cook your own meals as much as possible, and only eat what you cook.
