Has anyone heard of this diet? Has anyone tried it? I was talking to a guy in class last night that was telling me about this diet. Just curious to see what everyone else's opinions are about it.

    It's BS. Like other "diets", getting people to believe crap like this is just another way to scam people off their hard earned money. All diets have one thing in common........................calorie deficit. Stick with that for the win.

    Ok, so the diet is based on the premise that depending on your blood type, you process foods differently and therefore should have a fat/protein/carb balance tailored to your blood type. As far as I am aware, this theory has been debunked, so the blood type diet is hokum.

    It is true that different people process carbs / fats / proteins better than others - e.g. my mum loses more weight on SW on her green (carb heavy) days, whereas if I eat the same sort of diet I put on weight, and prefer the red (protein heavy) days. The SW diet is based on food group restriction rather than calorie restriction, so overall I don't find it works for me anyway. Each to their own though.

    Overall, to lose weight, put yourself in calorie deficit, and try to keep a healthy balance of carbs, fats and proteins, tweaked if you feel you want to or not if you don't.

    BTW I heard that the reasoning behind the blood type theory is that different blood groups are more or less common depending on your genetic ancestry (going back thousands if not millions of years), so is an indication of what area your ancestors were in and therefore what types of foods were available when your genes were evolving. The idea is that your body would be better adapted to the diet your ancestors had, and blood group is a way of measuring this.

    It's true that people's systems depend on their ancestor's evolution to some extent - e.g. a lot of east asians are allergic to alcohol, apparently because they sterilise water by making tea not alcohol, whereas caucasians went for alcohol and developed the necessary enzymes to break it down.

    However, as I said in my previous post, I have read that the blood type link to diet has been debunked.

    I don't think the blood type diet is designed for weight loss, in addition to being a bunch of unsupported hooey.
