The potential consequences of a low-calorie diet can include nutrient deficiencies, decreased metabolic rate, and loss of muscle mass. While some individuals may adopt low-calorie diets for quick weight loss, they often overlook the essential nutrients needed for overall health. Severe calorie restriction can lead to fatigue, weakened immune function, and decreased energy levels. Long-term adherence may trigger metabolic adaptations that make weight maintenance more challenging. Therefore, it is crucial to approach weight loss with balanced nutrition and adequate caloric intake to sustain health.
