As the popularity of low carbohydrate and ketogenic diets has increased, many myths and much misinformation has made its way onto the airways and into print. Old school nutritionists and doctors have often called low carb diets “extreme” and “dangerous.”
MYTH 1: CARBS ARE ESSENTIAL FOR ENERGY
There are essential fats (fatty acids) and proteins (amino acids) which you cannot manufacture in your body so they must come from the diet. However, dietary carbohydrates, which are broken down to glucose, are the only ‘non’ essential macro nutrient in the diet.
Yes, your brain needs glucose to function, but that doesn’t mean you have to eat it. Your body has a clever way of making its own glucose in the liver when required (a process called gluconeogenesis).
From an evolutionary perspective, it makes sense. As a species, we evolved to cope with extended periods of fasting. The body can cleverly switch to using an alternative fuel source called ketones, produced when the body starts burning its own fat stories. It’s a state called nutritional ‘ketosis’.
MYTH 2: KETOSIS IS DANGEROUS
Ketosis is often confused with another medical situation, called ketoacidosis. It sounds similar, but ketoacidosis is a complication of uncontrolled diabetes, which can be fatal, a far cry from a state of nutritional ketosis.
Even babies, soon after they are born, are in a natural state of ketosis.
MYTH 3: EATING FAT WILL MAKE YOU FAT
While fat has more “calories” than carbs per gram, it’s what happens in the body that matters. Unlike fat, carbohydrates (particularly refined carbs) are a potent stimulator of your fat-storing hormone, insulin.
Consistently high insulin levels means a consistent tendency to keep fat stored. That’s when those kilos creep up on you until one day you discover the spare roll around your waist (also known as the “insulin” roll).
Also, fat meals keep you fuller for longer so you end up eating less food. Whereas, refined carbs keep you “always hungry”, a phenomenon recently described by Harvard Doctor David Ludwig.
So, eating fat won’t “make you fat” because it controls satiety and reduces your requirement for (fat-storing) insulin.”
