OK, I have seen a lot of people around here saying that they are having a hard time losing that last little bit of fat. Usually people say "well just cut your carbs more, and you will lose it." Is that the right answer though? It some cases, maybe, but in others, maybe not.
What do you guys think of this study:
You can get the full study at obesityresearch.com if you search for it.
In this study, they gathered women that were either insulin sensitive or insulin resistant. They put half of each group on either a low carb or high carb diet. The results were astounding. On high carb diets the insulin sensitive lost more weight than the insulin sensitive women on the low carb. But for the insulin resistant women, they lost more weight on the low carb diet, and less on the high carb.
So how does this relate to getting that last little bit of weight off? Well, obesity or simply being over weight can cause a person to become insulin resistant. Due to this, most fat people will do best on a low carb diet. But, once these people start losing weight and get to normal weight, they will lose that obesity caused insulin resistance and become insulin sensitive...and then they stop losing weight on the low carb diet. The response to this on this board is "lower your carbs even more!!"...but is that smart?
I don't really think so. It is obvious from this study (although small, but results are still astounding) that different people react to diets differently. If you are having a hard time cutting that last bit of weight, maybe you should look to going on a high carb diet. Eat sweet potatoes all day if you would like. You can still stay primal, but it might be worth your while to increase the carbs.
Also, you can call me a troll, but I don't see how you can dismiss this research. Some people do better on high carb diets, and this study proves it. And if this wasn't true, how would you explain body builders eating high carb and having very low bf %. You could say "well, they take steroids" or something to that effect. But trust me, steroids don't make you skinny. If you don't believe that, you should do some research on different people in professional sports that have been busted for steroids. One example is Josh Barnett, who is an mma fighter that has been busted a bunch of times for steroids, and he has a spare tire.
Basically what I am saying is that if you are insulin resistant, low carb is the way to go. By default, most fat people become insulin resistant. So it is safe to say that low carb is good for losing weight for most fat people. But some fat people are still insulin sensitive, and this study shows that a high carb diet is better for insulin sensitivity. Also, body builders that eat high carb diets show that you don't have to eat low carb to have a 6 pack.
So, back to main point: if you are having a hard time losing that last 20 pounds of weight, try bumping up your carbs and see how you do. You might be insulin sensitive, and if that is the case, you will lose more weight on a high carb diet.
Call me a troll, but this is science, and this is what Mark was talking about with his post.
