Losing weight at a rate of 3 to 4 pounds per day is not considered safe or sustainable. A healthy and attainable weight loss goal is generally about 1 to 2 pounds per week. Rapid weight loss can lead to serious health issues, including nutritional deficiencies, loss of muscle mass, and gallstones, among others.
It's essential to approach weight loss through a balanced diet, regular physical activity, and proper medical guidance. If you're considering a weight loss plan, it's highly recommended that you consult with a healthcare professional or a registered dietitian to create a personalized and safe strategy that aligns with your individual health needs.
