A person who might considered chubby or something like that could probably safely lose 1-2 pounds per week as long as they are dedicated. Someone who is considered obese could safe lose about 3-5 pounds a week with dedication. If you are asking this question because you have 'lovehandles' (muffintops I believe are the newest nicknames), I say do not be ashamed of them, just wear clothes that actually fit you. you will feel better about yourself and you will be more comfortable.
Protein is a fundamental part of a healthy and balanced diet, but when you are in the daily grind, you may not get the proper amounts, especially if your goal is weight loss. Protein not only helps keep you satisfied for longer, it also contains amino acids like leucine, which has been shown in research to aid in maintaining muscle during weight loss. <<<
