Is this yo-yo dieting?Updated 6 months ago

No. 
If you know someone who wants to lose weight, it is important to warn them about the risk of protein deficiency, which can lead to yo-yo dieting. During weight loss, it is common to consume too little protein. Protein deficiency can lead to serious consequences, diseases, and muscle loss. For those who are looking for a long-term solution and do not want to fluctuate in weight like a yo-yo, losing weight by losing muscle mass is counterproductive. Muscles burn many more calories compared to the rest of the body, so you want to maintain your muscles to continue burning energy even after you have lost weight. This way, you won't quickly regain weight afterwards.
