So, is everyone a carb addict?

No. Not even. Think of the Pima Indians. Sure, 50% have bloated up -- but 50% of them haven't!

So, a lot of people would be a lot better off without any sugar, without any white flour and with reduced carbs.

But some people lose weight while eating half a cup to a cup of sugar a day (like this guy) and others do just fine in their blood work (like this one) but it doesn't usually hurt to start that way. South Beach Diet guidelines are an easy way to do that.

Bottom line:

So many folks are looking for a miracle program that has every nutrition and lifestyle choice under a microscope. Something to "guarantee" results, as it dominates all aspects of their life.

That article goes on to explain:

4. Low Carbs or High Carbs? Make a Choice.

Everyone knows that in order to lose fat you need to cut your carbs, right? Not so fast. Certain studies have shown that some people lose almost twice as much fat on high carb diets as they would on low carb diets. However, others will lose twice as much fat by doing the opposite and keeping their carbs low (3).

This is due to variations in insulin sensitivity and glucose tolerance. In many ways, insulin and glucose have a stimulating effect on the body. In people that are insulin sensitive, carbs increase sympathetic nervous system activity (think natural amphetamine), which translates into a boost in metabolism.

However, the thermic effect of carbohydrate ingestion varies greatly between different people. Insulin resistant people don't get the same metabolic stimulating effect. But people that are more insulin sensitive often feel like crap on low carb diets for this reason. Their metabolism quickly drops like a rock in response to low carbs, while more insulin resistant people will enjoy greater energy and mental clarity.

So, how do you tell which VIP club you're in? If you feel like death after a few days of low carbs and find that you don't lose much fat, you're probably more insulin sensitive. You can likely succeed with a diet as high as 50% carbs. If you feel on top of the world, you're probably more insulin resistant and will do better keeping carbs to 30% or less.

If you're still not sure which group you're in, test yourself. After eating a fairly high carb diet (at least 150 to 200 grams) for three days, and going at least 24 hours without exercise, have 50 to 75 grams of medium glycemic carbs, such as oatmeal, for breakfast.

Scroll down, ignore the advertisements and you will eventually get to a test to figure out what kind of diet will work for you (instead of making you balloon up even bigger).

If after an hour, you feel sleepy and are hungrier than you were before eating, then carbs aren't for you. If you feel more energetic, then carbs are your new training partner.
