Diet plays a vital role in most fitness regimes. And, some of the most popular diets out there encourage the restriction of carbohydrates.
Some of the most popular types of this diet include the ketogenic diet, low-carb Paleo diet, and the Atkins diet. They train the body to use fats as primary sources of fuel, instead of glucose.1 But, as with most diets, there are certain myths about low-carb diets that prevent people from trying them. Here are a few such myths, busted.
1. Low-Carb Diets Are Nutrient Deficient And Lack Variety
Consuming fewer carbohydrate-rich foods actually makes room for several other food groups that are high in protein, fat, vitamins, minerals, and dietary fiber.
Studies have shown that the rising number of diabetes and obesity cases in modern times are a result of not just lifestyle changes, but also modern foods like refined flour and confectionery, all loaded with carbs.2 Hence, the truth is that limiting food groups that are high on carbs allows you to try a greater variety of whole foods that are more satiating and nutritious.

Most critiques of restrictive diets come from the belief that limiting food might not satiate someone, hence causing hunger pangs through the day. This is believed to trigger cravings and, in turn, overeating.
3. Ketosis Caused By Low-Carb Diets Is Dangerous
There is a difference between diabetic ketoacidosis and nutritional ketosis. And, while both are a result of lowered insulin levels in the system, ketosis is not a harmful condition.6
Ketosis is essentially a bodily reaction as it begins using fats as a primary source of fuel instead of glucose. However, ketosis does run the risk of turning into ketoacidosis. You could avoid this by drinking plenty of water and increasing your fiber intake.8
Reduced Carb Intake Causes Heart And Brain Disorders
A low-carb diet reduces the risk of heart disease and improves cognitive performance. Studies state that a low-carb diet reduces fat deposits around the heart. At the same time, it is believed to increase the levels of high-density lipoprotein or HDL, which improve heart health.9 10
5. External Factors Lead To Weight Loss In Low-Carb Diets
It is believed that loss of water weight and lower calorie intake leads to weight loss in low-carb diets, not the diet itself. And, although there is a lot of water loss in the initial phase, experts state that it’s a way for the diet to turn the body into a fat-burning system.13
6. Low-Carb Diets Cause Tiredness Due To Lack Of Energy
On the other hand, complex carbohydrates found in beans, fruits, and vegetables, digest slowly, keeping you full, healthy, and active all day long. In other words, this diet does the opposite of causing tiredness.18
Low-carb diets aren’t just about cutting down your carbohydrate intake. They focus on the consumption of healthier food options that are rich in proteins, minerals, fiber, and an array of other nutrients. Focusing on the type of carbs you eat even on a low-carb diet, is the key to its success.
