What are the effects of too little or too much macronutrients?

Too little macronutrients can lead to malnutrition, resulting in muscle loss, weakened immune function, fatigue, and overall poor health. Conversely, excessive intake of macronutrients—especially carbohydrates, fats, or proteins—can contribute to obesity, metabolic disorders, and increased risk of chronic diseases such as Diabetes and Heart disease. Balancing macronutrient intake is essential for maintaining optimal health and supporting bodily functions.
