A high-fat diet, particularly one rich in saturated and trans fats, poses several health risks. These can include an increased likelihood of developing cardiovascular diseases, type 2 diabetes, and obesity. High fat intake can also lead to elevated cholesterol levels, which increase the risk of atherosclerosis. Moreover, excessive fat consumption might contribute to inflammation and metabolic disorders. A balanced approach, focusing on healthy fats like those from fish or nuts, is recommended for optimal health.
