This is because different foods have different effects on different processes in the body, regardless of their calorie contents. A calorie source affects your hormones and health differently. Different foods can affect hormone levels in different ways.
The different effects of glucose and fructose are a good example. These two simple sugars provide the same number of calories per gram, but your body metabolizes them in completely different ways.
A diet very rich in fructose is associated with insulin resistance, increased blood sugar levels, and higher levels of triglycerides and LDL (bad) cholesterol than a diet that provides the same number of calories from glucose.
However, the fruit, which contains natural fructose along with fiber and water, does not have the same negative effects. Furthermore, the type of fat in your diet can have different effects on your reproductive hormone levels. For example, diets rich in unsaturated fats appear to enhance fertility in healthy women.
Furthermore, replacing saturated fat with unsaturated fat in your diet may reduce your risk of heart disease, even though both types provide the same number of calories per gram.
The types of food you eat affect how full you feel
Your intake of nutrients affects your hunger and feelings of fullness. For example, eating 100 calories of beans will reduce hunger more effectively than eating 100 calories of candy.
This is because foods high in protein or fiber are more filling than foods that contain smaller amounts of these nutrients. Dessert, which is low in fiber and protein, is more likely to lead you to overeat later in the day, making it less likely that your “calories out” will match your “calories out.”
