What is the primary goal of a nutrition intervention for weight loss?

The primary goal of a nutrition intervention for weight loss is to create a calorie deficit. This concept is based on the principle that for weight loss to occur, an individual must consume fewer calories than their body expends. A calorie deficit leads to the use of stored fat for energy, which results in weight loss over time.

Creating a calorie deficit does not necessarily require drastic changes but can be achieved through a combination of reducing calorie intake and increasing energy expenditure through physical activity. This approach is sustainable and supports healthy weight loss, allowing for nutrient-dense foods to be included rather than eliminating entire food groups or drastically cutting calories.

Other options, while they can play a role in a comprehensive weight loss strategy, do not serve as the primary goal. Increasing exercise frequency may enhance calorie expenditure but alone may not lead to sufficient weight loss without addressing caloric intake. Eliminating all carbohydrates is not a sustainable or healthy approach for most individuals and can lead to nutritional deficiencies. Increasing meal frequency may help some individuals manage hunger and improve adherence but does not inherently create a calorie deficit on its own.
