Jumping through hoops, and my Blog List.

I'm seeing a curious thing. The VLC "camp" seems to be "jumping through hoops" to prove a point.
From http://davidbressler.com/2013/08/26/easier-harder/

From Neuron fuel and function (emphasis & formatting, mine):-
"Ketones and lactate do not drive reverse electron flow through complex I. Glucose can. Palmitate certainly can. What you want from a metabolic fuel depends on the remit of your cell types. Neurons within the brain preserve information by their continued existence.

This is best done by burning lactate or ketones. NOT glucose and, of course, not FFAs.

Anyone who claims that glucose is the preferred metabolic fuel of the brain has not though (sic) about what a neuron has to do and what an astrocyte actually does do. Or much about the electron transport chain."

Basically, glucose is bad mmm-kay. Also, anyone who claims that glucose is the preferred metabolic fuel of the brain is a dumb-ass. Damn our livers & kidneys churning out glucose! Are they trying to kill us?

∴ Carbohydrates are bad and must be avoided at all cost! This, of course, is utter nonsense.

Glucose can drive reverse electron flow through complex I. Can means that it's possible. Is it probable?

On a hypercaloric Western diet of excessive crap-in-a-bag/box/bottle, yes.

On a Kitavan diet of ~70%E from tubers, no.

On a diet of Basmati rice & beans, no.

On a diet of whole fruits, no.

See also Another crash and burn on low carb paleo and CrossFit. Enough of the 'carbs are evil' nonsense. Carbphobia is hurting a lot of people.

I have a list of blogs that I read on a regular basis. As a result of the bad science & cherry-picking displayed in various VLC blogs, I have deleted them from my Blog List.

Why you really can't outrun your fork.

Hat-tip to Yoni Freedhoff.
From http://www.blacksheepfitness.co.uk/you-cant-outrun-your-fork.html

See Effect of school-based physical activity interventions on body mass index in children: a meta-analysis.
"Meta-analysis showed that BMI did not improve with physical activity interventions (weighted mean difference -0.05 kg/m2, 95% confidence interval -0.19 to 0.10). We found no consistent changes in other measures of body composition."

Some people believe that if going to the gym isn't making them lose weight, they're not exercising hard enough. Chronically over-exercising can chronically raise serum cortisol, which makes the kidneys retain water, causing a stall in weight-loss, as well as causing raised fasting blood glucose, irritability, poor memory and a slower metabolic rate, due to the reduced conversion of thyroxine into tri-iodothyronine.

Don't over-exercise!

A healthy body weight is made in the kitchen, not the gym. Buy produce, cook it and eat it!

Although I totally support the use of low-carbohydrate/calorie diets for people with insulin resistance or Type 2 diabetes, now that I'm no longer insulin resistant, I can eat natural carbohydrates, without any problems.

A medium-sized (orange-fleshed) Sweet Potato takes only 4 minutes to bake in its jacket in a 700W microwave oven. The flesh is moist & sweet, unlike that of a Yam or potato.

I eat the whole thing, including the jacket. It's very filling and I'm still able to lose weight. For active and insulin sensitive people, a Kitavan-style diet is absolutely fine.
