OKAY...I will try not to make this too long. I am a nutritional therapist so I can be really passionate about nutrition and health. I get worried when people try a blanket "diet trick" like this. It is important to remember that we all have bio-individuality, meaning that something that might be good for me might not work for another person. There are so many factors including health history, age, race, environment, stress, mental health, etc. that need to be considered. Yes, it might be a quick fix for you, but it will only be temporary. Would you prefer rapid weight loss or lifelong health? There are much healthier ways of losing weight for a big event that concentrates on balancing your nutrition for the entire day. I don't want this to sound like a rant because I like Jillian Michaels and how she is trying to educate on fitness and health. This drink only targets water weight which will easily come right back, and could leave you very dehydrated. In the clip, she says diuretc drink which pulls water from the body. However, water is one of the most essential nutrients for the body and unfortunetly, one of the biggest nutritional defiiences in the United States. Then, her first tip off adding caffeine(which is a diuretic as well) will further dehyrate your body. I do agree with her tips about adding vitaminC(as long as it's not from juice), garlic, eating organically, and brazil nuts(but I would add that a variety ofnuts will broaden the nutrients you will receive). I hope this didn't make anyone upset...just my own nutritional two cents!
