BBC Fat vs Sugar review

I don't know if you managed to see it last night, but on BBC there was a Horizon investigation. Two twin doctors went on diets, one was high fat and the other was high sugar and carbs.

Firstly I'm delighted that the subject is on the agenda at all.
But if I'm honest the program was very disappointing. It made the anti sugar lobby to be an American based thinking.
Doctor X went on the high fat diet. But he didn't have any vegetables or leafy greens because of the carbohydrates. Which was disappointing because I'm sure that nearly all that go on a low carb diet also have greens and vegetables. There are carbohydrates in the vegetables but they are hidden in with the fiber thus not resulting in a spike of Insulin. I don't think any of the low carbers out there are NO carbs like the doctor in this experiment was.
His bloods were taken before and afterwards. His cholesterol hadn't changed after a month of high fat eating. He had also lost 2kg of fat but alarmingly 2kg of muscles also. This was used to beat the high fat mantra saying that it is a diet of muscle loss.
But my biggest grievance against it was that the "specialist" said that the high fat diet was dangerous for him. They did a blood glucose test afterwards and it appeared that doctor x was nearly diabetic, that he was Insulin resistant. The specialist concluded that this was because the body was getting used to not having insulin that after that it became unable to start again.
This though isn't the true. Its true that after a spike of sugar for the first time, you will act like a pre-diabetic and fail to produce the Insulin spike. But from then after you will return to normal. Which wasn't picked up on.

Dr Robert Lutzig was also on the show telling of the dangers of Fructose and Glucose, but the English doctors were skeptical. But it was good to see the doctor, and hopefully people can do their own research. They also mentioned about cholesterol not being the danger that we have thought in the past. Which was a good little seed to plant.

How about the high fat diet that was given to the twin Chris?
Well he didn't lose as much muscle in the experiment but then he only lost half the fat compared with his twin. He didn't feel as full and needed to snack a lot more than the high fat diet. He also ate more calories than his twin as he didn't feel as full. But, the program seemed to prefer the high sugar diet than the high fat diet.

So what was the conclusion of the program?
Well what they decided was that the danger was in the mix of fat and sugar. They said that its the mix of the two that does nothing to Grelin and thus makes us over eat. Yes, they concluded that it was all down to calories again.

Personally, I feel that the study wasn't conclusive enough. There's many more interesting parts to the show, but what do you think? Did you get a chance to see it? Do you have a different opinion to me?
