Have you heard about this professor who only ate junk food for 2 months? He lost 27 pounds!
A quick summary: He ate twinkies and brownies and chips, but also a daily vitamin, protein shakes, and a few carrots and he limited his food intake to around 1800 calories a day. Over the course of his diet he lost weight and lowered his cholesterol. His reasons for this diet are documented in the article.
Here are my thoughts:
1. Like I've said before, it is all about math. Figure out how many calories you need and eat 500 a day fewer. (To lose a pound you must have a 3500 calorie deficit. To lose a pound a week, which is healthy, divide by 7 and you get 500). It doesn't matter WHAT you eat!
2. However, there is enough evidence out there that you should eat a more healthy diet... duh. If you need your body to work correctly (workout, repair itself, stay well), then you should eat to support that.
3. I am pretty sure this will NOT become a fad diet, or at least I hope not. But I want to call out a problem with most fad diets (low carb, Atkins, The Zone, paleo, caveman diet); they are all based on high calorie, high fat food. If your goal is to lost weight? You have to really, really watch the total calories. If your goal is to lose fat? Then nuts and red meat are going to make that harder. Eat whatever you want, just know that the diet you are following is a fad and doesn't matter in the long run.
4. You do not have to cut out food you love to lose weight. Again, you do not have to cut out food you love to lose weight. Quit doing that! If you love a brownie or a big bowl of pasta? Eat it. Just compensate for it somewhere else.
5. You have to plan to keep up any form of diet. This dude even planned his days, and it was buying in bulk on the first day because all of his "food" would last though a nuclear war. It takes making a list, planning your meals, preparing food the day before or on Sunday for the week, transporting your food to work with you, and researching what you are putting in your body. I'm important enough to myself to do this... and you should be too.
Now, these are just my opinions. I've formed them by using the ideas myself, reading a lot of books and articles about diet, and by observing others. Take 'em or leave 'em. But most importantly, this post is not intended to encourage or advocate a Twinkie diet! Unless, of course, that would make you happy...
