Carbohydrate, protein, and fat are essential for health maintenance, growth, reproduction, immunity, and healing. Deficits or excesses of any of these nutrients may compromise these processes, resulting in poor health outcomes, which vary depending on the macronutrient in question and the life stage of the affected person.

Carbohydrates, in the form of starches and sugars, is the main energy source in the human diet, typically providing 50% or more of total calories. Also, not all carbs are bad foods like fruits, vegetables and whole grains, may be high in carbs and calories sometimes, but they are not empty they deliver fiber, protein, B vitamins and other nutrients.

People often turn to low-carb or keto diets as a quick way to lose weight — keto diets are known to induce rapid weight loss in the first few weeks, but it’s not always sustainable. For one thing, every body is different and won’t see the same results on a low-carb diet, and secondly, it’s hard to keep up with a carb-free diet long-term. 

When you completely cut carbohydrates out of your diet, you could put yourself at risk for nutrient deficiencies if you don’t replace those nutrients with other food sources. For example, about 70% of Americans don’t get enough magnesium, due to low carb dieting, an important mineral that cells need to “turn off” stress.

You may also be missing out on key nutrients that aid in digestion, such as fiber, and immune health.

Most importantly cutting out carbs (or any macronutrient) can lead to disordered eating patterns as cutting out food groups has been associated with disordered eating habits. This is particularly true with regard to orthorexia nervosa, or an obsession with healthy eating that progresses to the point of a disorder.
