Health risks associated with low-carb diets include potential nutrient deficiencies, digestive issues, and increased fatigue. These diets can lead to inadequate intake of essential vitamins and minerals, especially from fruits, vegetables, and whole grains. Additionally, some individuals may experience adverse effects such as keto flu, characterized by headaches, fatigue, and irritability during initial adaptation. Long-term adherence can lead to unhealthy dietary patterns, resulting in metabolic imbalances or increased cholesterol levels, thus necessitating careful monitoring if one chooses a low-carb lifestyle.
