The risk of nutrient deficiencies in overly restrictive diets is significant, as limiting food choices can deprive the body of essential vitamins and minerals. These deficiencies can lead to various health issues, including weakened immune function, decreased energy levels, and impaired overall health. Over time, individuals might experience negative impacts on bone density, cardiovascular health, and even mental well-being. A balanced approach to nutrition—focused on moderation rather than strict restriction—ensures the body receives all necessary nutrients for optimal functioning.
