The idea of cutting out all fats from a diet may sound like a fast way to lose weight, but it can do more harm than good. Healthy fats, like those found in avocados, nuts, and olive oil, are vital for brain function, hormone production, and heart health. A no-fat diet can result in deficiencies in essential fatty acids, leading to dry skin, weak immune function, and poor energy levels. The key is not to avoid fats but to choose the right kind—unsaturated fats—while limiting saturated and trans fats. A balanced approach to fat intake is the best way to support overall health.
