I was recently asked to comment on this “new” DNA diet. This concept is nothing new, and is remarkably similar to the “blood-type” diet, if a little more practical in the advice it gives. For only about $390 (Canadian) you can have your DNA analysed and a diet (and exercise regime) prescribed. Despite the fact that there are billions of DNA sequences, there are only four, yes, four, possible diet prescriptions. From the sounds of it, all of these possible diets are sensible and all of them would lead to weight loss in the dieter. However, the notion that diet can be prescribed according to DNA is ludicrous and the amount that you have to pay to receive a healthy eating plan and fitness regimen is even more ridiculous. Sure, you’re going to lose weight while you’re following this diet plan but what about when it’s done? This is the problem with diets. They’re short-term solutions to a life-long problem. Unless you’re willing to eat that same diet for the rest of your life this plan is guaranteed to fail. In order to maintain weight loss you need to adopt habits that you’re willing to sustain for the rest of your life.
