**LOL** I read that person's blurb over and over till my eyeballs glazed ... it makes no sense whatsoever. And definitely unresearched, unfounded and without any factual substance at all. They'd make a great Televangelist!!! ..
Anxiety and depression are two mood disorders with very similar physiological & neurochemical imbalances. Probably more than blood sugar itself .... INSULIN has a huge effect on the levels and responses of these chemicals and hormones. Lowcarbing won't be a total cure for anxiety, but it will definitely help keep insulin levels under control.
What happens, as you know, when you eat carbs your blood sugar goes up and insulin is dumped into the bloodstream to deal with it. Rising insulin levels also trigger the adrenal gland to produce adrenalin, cortisol and other hormones ... since it perceives some kind of "emergency" or threat, due to the surge of insulin. The cortisol and adrenalin triggers a whole cascade of hormones and neurochemicals .. dopamine, noradrenalin, histamine .. etc .... revving up the body .. the heart speeds up, blood vessels dilate, flushed face, sweating, etc .. for most people, the body copes and adapts, and things settle down. For some of us, the gate-keeper in the brain doesn't respond properly, and we stay in this anxious, ready-for-the-threat-that-isn't-there state...
.. For others, the response is opposite, and levels of neurochemicals drop, for example serotonin.
In Protein Power Lifeplan, the Drs. Eades have some interesting things to say about the role of CHOLESTEROL in depression and anxiety disorders (pp 262 - 264). Briefly, researchers have discovered that depriving their subjects of dietary fat - in particular dietary cholesterol - resulted in changes in mood and disposition that included depression, withdrawal and aggressive behaviour.... An examination of the biochemistry of cholesterol makes at least one reason for these findings clear: cholesterol acts in the brain to block the re-uptake of the mood-enhancing neurochemical serotonin. This is precisely the action of the class of anti-depressants such as Prozac ... the SRI's, serotonin-reuptake inhibitors.
Dietary cholesterol - that which you get from the foods you eat - does not affect the body the same way as the cholesterol your body makes itself. When your liver has to make its own cholesterol (because of a lowFAT, low cholesterol diet), it's usually of the LDL variety (the so-called "bad" cholesterol) and also produces more triglycerides as well. When you consume sufficient cholesterol from your foods, the liver doesn't have to produce this extra cholesterol and blood fat. This is a very simplistic explanation, I'm definitely not an expert .. but the gist of it is .... get your cholesterol from your food - eggs, dairy, meats ... and a healthy dose of omega-fats from vegetable and nut oils, and fatty fish .... Your brain and YOU will be much happier, and your liver won't have to produce the artery clogging LDL and triglycerides.
On the subject of ketones, they are an efficient fuel and energy source for the brain, muscles and organs of the body. There are only a few tissues that must have glucose ... which the liver can manufacture quite nicely from protein. The human body is designed to function very well for long periods of time using ketones as fuel.
