Common barriers to maintaining a balanced diet include lack of time, lack of knowledge, and limited access to healthy options. Many individuals struggle to find the time to prepare nutritious meals amidst busy schedules, leading them to opt for convenience over health. Additionally, a lack of understanding regarding portion sizes and the nutritional value of foods can contribute to poor dietary choices. Limited access to fresh produce or healthy foods in certain areas can further complicate efforts to maintain a balanced diet, ultimately leading to unhealthy eating habits and negative health outcomes.
