A ketogenic diet is a high-fat, regular protein, extremely low-carbohydrate diet. This kind of diet essentially forces your body into burning fats as opposed to carbohydrates by making your liver produce ketone bodies which transport themselves into your brain and are used as an alternate fuel source when there is no glucose. This diet is used to help people prevent epileptic seizures. It should be its only use, yet for some reason, it is a fad diet employed by “nutritionists” and “doctors” who claim that if your diet has plateaued, then going on a ketogenic diet can be a safe and effective way to kick-start your weight-loss or take it to another level. There are many reasons why this literally makes no sense. Because starving your brain is not smart. Plus the damage it can do to your body makes this diet even dumber.
Your brain primarily uses carbohydrates as its main fuel. So when you put yourself, or God forbid, someone else puts you on this diet, and you are not epileptic, you are literally starving your brain of its necessary and primary fuel source. Then, there are a myriad of adverse reactions and complications to boot. Here they are in no particular order: constipation, hypoglycemia, raised cholesterol levels, growth impairment in children, bone fractures, kidney stones, hypercalcuria (excess calcium in the urine), menstrual irregularities or amenorrhoea or loss of a period altogether.
Ketogenic diets are extraordinarily hard on your kidneys and liver and can impair the function of your brain. Not smart. So, please, if a nutritionist tries to sell you on a ketogenic diet, take your money elsewhere, because she literally has no idea what she’s talking about.
