Final answer:
A person who is obese should follow a balanced nutritional therapy plan that includes whole foods from all basic food groups, as per evidence-based dietary guidelines, rather than opting for fad diets which are not sustainable and may lack essential nutrients.
Step-by-step explanation:
The best nutritional therapy plan for a person who is obese is to consume foods from the basic food groups which provide a balance of vitamins, minerals, proteins, carbohydrates, fats, and fiber essential to good health. This approach is aligned with evidence-based dietary recommendations that focus on whole foods and a healthy eating pattern. It involves limiting intake of energy-dense foods high in fat and sugar and increasing consumption of high-fiber foods.
Evidence-based dietary recommendations suggest a balance of vegetables, fruits, whole grains, lean protein, and low-fat dairy. This combined with an active lifestyle helps in managing weight effectively. Fad diets such as the Zone Diet, Atkins, or Sugar Busters might offer quick weight loss but are often not sustainable and may lack essential nutrients.
Ultimately, making long-term lifestyle changes and incorporating healthy dietary choices are more effective than quick-fix diets. Obesity is preventable and treatable through such balanced diets and increased physical activity without resorting to extreme dietary restrictions that fad diets might impose.
