That's the biggest concern I have about recommending keto in general. Dietary supplements aren’t overseen by the FDA, meaning that they’re not evaluated for safety and efficacy in the same way that food and medications are and you may not be getting exactly what you pay for. And if you are? Consuming certain nutrients in supplement versus food form can induce oxidative stress rather than treat it, causing more harm than good to organ tissues. The end result: increased risk of chronic disease, including heart disease and some cancers.
Variations on the Johns Hopkins protocol are common. The initiation can be performed using outpatient clinics rather than requiring a stay in hospital. Often, no initial fast is used (fasting increases the risk of acidosis, hypoglycaemia, and weight loss). Rather than increasing meal sizes over the three-day initiation, some institutions maintain meal size, but alter the ketogenic ratio from 2:1 to 4:1.
The nerve impulse is characterised by a great influx of sodium ions through channels in the neuron's cell membrane followed by an efflux of potassium ions through other channels. The neuron is unable to fire again for a short time (known as the refractory period), which is mediated by another potassium channel. The flow through these ion channels is governed by a "gate" which is opened by either a voltage change or a chemical messenger known as a ligand (such as a neurotransmitter). These channels are another target for anticonvulsant drugs.
A word of warning: be very wary of “keto” or “low carb” versions of cakes, cookies, chocolate bars, candies, ice cream, and other sweets. They might maintain people’s cravings for a sugary taste, and can make you eat more than you need. They are often full of sugar alcohols – that can raise your blood sugar – and artificial sweeteners, whose health impacts are not yet known. Weight loss may also stall or slow. Learn more
