Dieting vs healthy eating

So in the discussion of dieting, i don't diet. I have plenty of books regarding weight loss and cooking.

My former endocrinologist gave me a choice of the Zone or South Beach.

Well, i am not much for prepackaged food as i am for cooking from scratch so I of course chose the Zone.

The reason I was recommended this is that it is hard for me to get enough caloric intake in a day that is balanced/ healthy. 

So yes, if you eat healthy, you can sometimes be looking at the end of the day with only 900 calories on the balance sheet and thinking can I eat 2 protein bars to reach my 1300 calories and not throw it back up b/c you are already so full.

The result of having a small stomach and not eating enough food is that you can gain weight and not be getting your nutritional needs met.

Don't get me wrong I love and eat unhealthy foods and will cook them willingly or go out and buy them. But instead of eating a 1/2 dozen Krispy Kreme donuts, i have my free one and then my favorite Iced Cream Filled. Of course, now a days, I get the Cram Filled withou tthe Chocolate Icing as I can't seem to handle that much sweetness. I also limit myself to a 3-6 month range between donuts. That way it is a special treat and not a habit.
