What is a potential consequence of following a low carbohydrate diet?

Following a low carbohydrate diet can potentially lead to low levels of B vitamins, as well as vitamins A and C, primarily because many carbohydrate-rich foods serve as sources of these essential nutrients. Whole grains, fruits, and vegetables, which are often limited or eliminated in low-carb diets, are significant contributors to the intake of B vitamins, including thiamine, riboflavin, niacin, and folate. These vitamins play key roles in energy metabolism, red blood cell production, and overall cellular health.

Additionally, fruits and vegetables, which are reduced in a low-carb diet, provide antioxidants such as vitamins A and C, which are vital for immune function, skin health, and cellular protection against damage. When these food groups are restricted, there is a risk of nutrient deficiencies, which can have a cascade of negative health effects, including compromised energy levels, mood disturbances, and impaired immune function.

The other potential choices do not accurately reflect typical consequences of a low carbohydrate diet. For example, high levels of glucose are unlikely if carbohydrate intake is significantly reduced, and low zinc levels are not directly correlated with a low-carb diet. While some may argue about increased endurance, this typically depends on individual adaptation and is not universally applicable across all populations.
