Advocates point to scientific trials demonstrating the efficacy and safety of low carb diets. Several independent clinical trials have shown that low carb diets can successfully be used to lose weight. These trials found that, in the short term, risk factors for heart disease and diabetes � such as blood serum cholesterol and insulin levels � tended to improve in spite of increased consumption of saturated fat and cholesterol. The trials were of short duration, and were not able to assess the long-term health effects of the diet.

Critics of low-carbohydrate diets also point out that from an environmental point of view an increased consumption of animal protein places a great burden on the world's natural resources and is not sustainable. They also point out that the explosive growth in global population over the last few centuries was only possible because of grain crops.

Critics contend that low carbohydrate diets are not without harmful side effects. Very low carbohydrate consumption can lead to the metabolic state called ketosis, which may cause headaches, tiredness, nausea, dehydration, dizziness, and an unusual sweet-smelling breath odor. The lowered intake of dietary fiber that often accompanies dramatically reduced carbohydrate intake (such as in the Induction stage of the Atkins diet) can result in constipation if not supplemented.
