What are your client’s specific goals? From the initial numbers you have provided, it looks like your client has lost the weight rather quickly. Based on your comment that she doesn’t think that is good enough, my thought is that there are more underlying issues that need to be addressed and more questions to be asked. I would use caution with anyone who wants a quick fix because the chances of gaining the weight back are pretty high. I would revisit her goals and let her know that these changes take time.
Weight loss and changes in body composition should be a gradual thing (1 to 2 pounds per week)–in order to maintain that loss and make permanent lifestyle changes. Quick fixes don’t work for the long run.
