Sugar vs Fat BBC2.

The worst science programme I've seen. Errorama. Identical twin brother doctors go on no carbs and only carb diets.

What are the errors?

1. Proteinman appears to eat no carbs. He gets a difficult mental task for the day after a couple of weeks. He would've been ketotic and would have had poor concentration. On a LCHF (Low carb high fat) diet the minimum carbs is not 0 but 20g and you are told to eat more if you feel woozy.

2. After a hard bike workout they are given a gel (carbman) and some butter (proteinman). They race up a hard hill. Carbman wins easily. Only problem is he's a good bit lighter (20lb or more, I reckon )and being an identical twin they have the same power output. He has to win. 20lb will give you ten minutes in a 2000ft climb or two minutes on Box Hill which is a 400 ft climb.

3. Lipids are supposed to be identical, but there's no breakdown. LCHF usually better than anything else.

4. This is the worst. Carbman's insulin has risen but his resting blood sugar is the same. Proteinman's blood sugar has risen but his insulin is not that high. A bearded labman (A Dr.(PhD) Richard Mackenzie) says...
"your sugar is raised, on this diet and your insulin is low". This is interpreted as pre-diabetes and the lowish insulin is because his body is about to pack in insulin production thereby making him diabetic. This diet is not good for him etc. I've actually emailed him since and asked how could a diet which is demonstrably the best for type 2 Diabetes possibly do this. All I got was evasion and I'm too busy etc.
I'm a doctor myself and I couldn't believe such an outcome. It would be impossible for a diet which is THE most successful at controlling type 2 diabetes to make someone diabetic. I thought to myself, this is either an error or it's due to ketosis.
Ketosis is a biochemical condition the body goes into when you're either starving or eating little or now carbohydrate.
Lets look it up.

In this, the very first link I found was exactly what was found in him. A raised blood sugar and mildly raised  insulin. This is a normal finding in ketosis and has no sinister implications whatsoever. What it in fact is is the body raising the basal level of sugar in the blood, as on this diet it's not going to vary much. The degree of liver insulin resistance in this case protects the brain's glucose supply.When eating a mixed diet, the blood sugar shoots up and down depending on the carbs you eat.
This is a huge blunder in a programme like this. If something doesn't make sense, look it up.
The problem is that the person seeing such a business may not know enough to see it's a problem.

When you take these errors into account you see that the programme was absolutely worthless, in fact a black mark on its makers.

Grrr!

Why Carbohydrate is the bad boy, not fat, as simply put as it can be.

The fat you eat is not turned into bad stuff in the blood.

The bad stuff in the blood is made by the liver (this has different lab characteristics)

The liver makes this as a response to carbohydrates (starch and sugar) in the diet.

The bad stuff in the blood is NOT what primarily gives you heart disease but acts as a marker for it possibly being present.

The carbohydrate with the resultant high blood sugar AND high insulin is the side-effect which produces the arterial disease.

One sentence then:

Excess carbohydrate raises blood sugar and insulin which in the course of time, damages arteries and the liver changes the blood lipids which may act as a marker for the damage, but the dietary intake of GOOD lipids is not involved.
