A diet plan refers to a specific eating pattern or regimen that is designed to help an individual achieve their desired weight loss, nutritional goals, and overall health objectives. It typically involves consuming certain foods in specific quantities while avoiding others, along with incorporating exercise routines for optimal results. The purpose of a diet plan can vary from person to person - some may want to lose weight, while others might aim to maintain their current weight or improve their overall health through proper nutrition and physical activity. Ultimately, the goal is to create a sustainable eating pattern that promotes wellness and supports an individual's unique needs and lifestyle.
