Which of the following does not contribute to positive nutrition outcomes?

Eliminating all carbohydrates is not conducive to positive nutrition outcomes. Carbohydrates are one of the three macronutrients essential for providing energy, particularly for the brain and during physical activity. They are also important for overall health, as they can be found in a variety of nutrient-rich foods, such as fruits, vegetables, grains, and legumes. A diet devoid of carbohydrates can lead to nutrient deficiencies, impaired energy levels, and an overall lack of balance in one's dietary intake.

In contrast, focusing on body composition, eating a balanced diet, and staying hydrated are all practices that support positive nutrition outcomes. Maintaining a balanced diet that includes a variety of food groups ensures that an individual receives the necessary vitamins, minerals, and macronutrients. Staying hydrated is critical for various bodily functions, including digestion, temperature regulation, and nutrient transport. Therefore, embracing a holistic approach to nutrition rather than overly restrictive diets will yield more favorable health outcomes.
