Final answer:
Excess protein intake can lead to weight gain if calorie intake is not accounted for. It is important to consume protein in appropriate amounts within a well-balanced diet for effective weight management.
Step-by-step explanation:
Excess protein intake can affect weight management in different ways. While protein is an important nutrient for building and repairing tissues, consuming more protein than your body needs can lead to weight gain. This is because excess protein, just like excess calories from any other source, can be stored as body fat. Additionally, consuming excess protein often means consuming less of other important nutrients, such as carbohydrates and fiber, which can impact overall diet quality and weight management.
A study published in the American Journal of Clinical Nutrition found that a high-protein diet can lead to weight gain if calorie intake is not accounted for. The study showed that participants who consumed excess protein but did not reduce their calorie intake actually gained weight over a period of 8 weeks.
It's worth noting that protein is more satiating than other macronutrients, such as carbohydrates and fats, meaning it can help control appetite and promote feelings of fullness. This can potentially aid in weight management, as it may help reduce overall calorie intake. However, it's important to consume protein in appropriate amounts within a well-balanced diet.
