Is there any medical proof to the claims about pomegranate juice or cinnamon?
There is some evidence that pomegranate juice contains a lot of antioxidants, and we know that consuming antioxidants can help prevent disease. In most research, however, it's difficult to make substantial claims without having large controlled trials.

Is there a connection between obesity and sleep disorders?
There is a clear link between poor sleep habits and obesity. In the last few years there have been a number of studies that support those who don't sleep much because they are busy or because they have insomnia are at much higher risk of becoming overweight and obese. 

How to Exercise with Disabled or Weak Legs
Spending long hours sitting in a wheelchair or in a bed can not only be uncomfortable, but can also lead to weight gain, weakened muscles, joint and muscle stiffness and weakened heart and lungs. Thus, moving as much as possible is very important for anyone with disabled or weak legs. This is easier said than done, because quite a few exercises, particularly aerobic exercises, involve the use of functioning legs.

Pomegranate Juice and Emphysema

There is a great deal written about the protective effect of antioxidants these days. Because of high levels in fruits and juices their consumption tops the list of those with the most benefit. One fruit juice with an abundance of antioxidants is pomegranate juice (PJ). In the test tube pomegranate juice has over three times the antioxidant activity of red wine or tea.

The stress of oxidation plays a large role in the decline of lung function in people with emphysema. To evaluate whether the antioxidants in pomegranate juice are effective for patients with this high stress condition, scientists had two groups drink either PJ or a PJ flavored placebo for 5 weeks (Eur. Journ. Clin. Nutr. 2006; 60(2): 245 - 253). They then evaluated lung function as well as total antioxidants in the bloodstream.

No difference was found between those drinking juice and those using placebo. Not only were there no differences in lung function but there wasn’t a significant rise in antioxidants in the blood stream of participants. It appears that the most important of the antioxidants was processed in the intestine and never absorbed.

What this means for you

Pomegranate juice tastes good and the antioxidants in it may be effective for some conditions--but not for emphysema.
