A diet high in fats, especially unhealthy fats like saturated and trans fats, can negatively impact your health in various ways. While some argue that such diets can promote fullness, balance hormones, and boost brain function, it’s essential to remember that not all fats are the same. The main side effects of a high-fat diet include weight gain, a higher risk of heart disease, insulin resistance, nutrient deficiencies, and chronic inflammation. Understanding these risks will help you make more informed decisions about your diet and overall well-being.
