How does the caloric content change when switching from whole milk to reduced-fat milk?

When switching from whole milk to reduced-fat milk, the caloric content decreases. Whole milk typically contains about 3.25% fat, contributing to a higher overall calorie count due to the fat content. Reduced-fat milk, such as 2% or 1% milk, has a lower fat percentage, which directly correlates to a reduction in calories since fat is more calorie-dense than carbohydrates or proteins. For example, a cup of whole milk may have around 150 calories, whereas a cup of 2% milk might have approximately 120 calories. Therefore, the change in fat content leads to a significant decrease in the overall caloric content when shifting to reduced-fat milk. This shift can be beneficial for individuals looking to manage their caloric intake while still obtaining the nutritional benefits of milk.
