So, how does a ravenously hungry human being then lose weight?

It's NOT by indulging in more carbohydrates. According to Peter at Hyperlipid Blog, you need fat and protein, unprocessed (closest to nature) foods, and daily exercise.

Here's the current, crazy advice:

We all know that if you are a type 2 diabetic you must have been greedy for years before getting your just comuppance (thinks your GP). It's self evident that fat people get fat by eating too much food and obviously it's the dietary fat which is the main factor. Obesity is clearly the cause of type 2 diabetes (except in skinny type 2s and those naughty extremely skinny people with lipodystrophy, duhh). It's also self evident that once you have a serious blood sugar regulation problem you should eat as much sugar as possible and avoid fat like the plague because otherwise you might get even fatter, which gives you more blood sugar problems (ADA advice).

So a type 2 diabetic should eat a diet which is as carbohydrate based as practical and make sure they loose weight, lots of it. I think it's reasonable to say that that's current diabetes advice...

...Diabetic rats on the ADA diet are RAVENOUS. Oops, sorry, gluttenous. Diabetic rats on a genuine high fat diet are not. They're not very diabetic either.

Now take that to humans. I don't think humans are particularly different to rats. Telling a human diabetic to eat a carbohydrate based diet will bump up their neuropeptide Y levels and will drop their corticotropic releasing hormone levels. They'll be ravenous. Bit of a cruel trick really.

But here's the really funny bit.

You then tell them they MUST loose weight. When they fail to loose weight, you underline the bit in their case notes where it says glutton/failed to comply.

Don't laugh too much, it's not funny really.

Cut the carbs, folks, and get lean, energized, strong, and healthy. Even if you don't have full-blown diabetes, prevention is key.
