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.
This is why Gaspari Nutrition chose highly branched cluster dextrin for what we consider to be the gold standard of recovery and performance drinks. This high molecular weight carbohydrate has a special helical structure, which gives it unique properties unlike many of the corn starches or polysaccharides out there. I'll be real with you and say this stuff isn’t cheap, but you certainly pay for what you get, and highly branched cluster dextrin is unlike any carb source I've found – especially if you want to control blood sugar levels and gut issues.
Hey Alex, thanks for commenting and great to have you as a new listener! For this kind of thing, because it requires so going into detail, I'd suggest you book a consult with me by going to www.greenfieldfitnesssystems.com/ben and choosing 20 or 60 minutes and we'll get you scheduled to go into detail there. Thanks!
Meat – like grass-fed selections – and fresh veggies are more expensive than most processed or fast foods. What you spend on Keto-friendly foods will vary with your choices of protein source and quality. You can select less-expensive, leaner cuts of meat and fatten them up with some oil. Buying less-exotic, in-season veggies will help keep you within budget.
In a state of ketosis, your body breaks fat down in the liver and converts it into ketones to be used for energy. Fat doesn't generate an insulin response, so insulin levels remain stable. This makes it much harder to store excess fat, and easier to tap into body fat stores for energy. Not only will this allow you to maintain your weight, but it will greatly encourage weight loss.
Shifting your metabolism and achieving ketosis may speed up weight loss and result in other health benefits, like more energy and a lower blood pressure. But while ketosis is a preferred nutritional state for some people, it isn’t recommended for everyone — and it’s not a good long-term eating approach due to its restrictive nature, which may lead to potentially dangerous nutritional deficiencies.
Ketosis is deliberately induced by use of a ketogenic diet as a medical intervention in cases of intractable epilepsy. Other uses of low-carbohydrate diets remain controversial. Carbohydrate deprivation to the point of ketosis has been argued to have both negative and positive effects on health. Ketosis can also be induced following periods of fasting (starvation), and after consumption of ketogenic fats (such as medium chain triglycerides) or exogenous ketones.
There are a few ways of pushing your body into ketosis, including sustained periods of fasting and following a ketogenic diet (as the name so obviously suggests). Dr. D’Agostino also suggests spending some time in the sun and heat. Getting out in the sun lowers glucose and raises ketones, and can push you into ketosis, especially if you’ve been fasting.
