The concept of "crowd out" in nutrition refers to what practice?

The practice of "crowd out" in nutrition revolves around the strategy of starting meals with nutritious foods. This approach emphasizes the idea that by prioritizing the consumption of healthy, nutrient-dense foods at the beginning of a meal, individuals are more likely to fill up on those foods. Consequently, there is less room or appetite for less nutritious options that might typically be included in a meal, such as processed snacks or high-sugar items. This method encourages a shift towards healthier eating habits without the need for strict elimination or restriction, making it more sustainable in the long term.

Filling up with high-calorie foods first would not align with the "crowd out" concept, as that would potentially lead to increased consumption of less nutritious items rather than replacing them with healthier choices. Eliminating all carbohydrates from the diet is a drastic approach that doesn't reflect the crowd out strategy, which is more about balance and moderation. Similarly, avoiding snacks between meals does not directly relate to the concept of starting meals with nutritious foods, as it does not focus on the food choices made during meals themselves.
