Common misconceptions about fat loss and calorie deficits include the belief that all calories are the same and that extremely low-calorie diets are effective long-term. In reality, the quality of food matters, as whole foods tend to be more satiating compared to processed foods. Another myth is that you can target fat loss in specific body areas, when in fact, overall body fat reduction occurs through a gradual calorie deficit. Understanding these misconceptions leads to healthier, sustainable weight management practices.
