ISSA Nutritionist Practice Exam

Which nutrient is typically reduced in a low-energy diet to promote weight loss?

1. Fat

2. Carbohydrates

3. Calories

4. Proteins

The correct answer is: Calories

In a low-energy diet, the primary focus is on reducing overall caloric intake to create a calorie deficit, which is essential for promoting weight loss. When the total caloric consumption is lowered, it allows for potential weight reduction by forcing the body to utilize stored energy, primarily fat. Calories are a measure of the energy that food provides, and by reducing calorie intake, the body seeks alternative sources of energy, leading to fat breakdown and, subsequently, weight loss. While macronutrients like fat, carbohydrates, and proteins can also be adjusted in a diet, the central principle in a low-energy diet is to cut down on the total number of calories consumed rather than limiting specific macronutrients alone. It’s important to note that while calories are reduced, the balance of nutrients should still be considered to ensure that the body receives adequate nutrition, which supports overall health while losing weight. This approach prioritizes creating an energy deficit without necessarily focusing on reducing fat, carbohydrates, or proteins specifically, as these nutrients can still play important roles in satiety, metabolism, and overall health when consumed in appropriate amounts.
