Well yes, of course your diet should be well-rounded and contain all the necessary vitamins, fibers, protein your body needs. My comment was more a reaction to all the different kinds of diets, and how they're supposedly a better way to lose weight than the previous diet. If you want to lose weight, and you already have a varied diet that meets your body's daily intake requirements, it can be useful to calculate your calorie consumption and burn rate and try to tweak both of those so that you end up with a caloric deficit. Of course this only directly affects your weight, and you need to also take care of your body's general health. I would hope it's obvious to most that you shouldn't start a wood chip diet.
