Drink Away Your Weight?
New Diet Beverages Claim To Burn Calories — Are They Too Good To Be True?
(CBS) Wouldn’t it be great to be able to drop some weight simply by sipping on a tasty green tea-based beverage? That’s what the manufacturers of some new diet drinks have been claiming – but are these drinks too good to be true?
The Saturday Early Show turned to clinical nutritionist Samantha Heller, a contributing editor at Health magazine, to find out whether these drinks can really do the trick for dieters.
“They do not promise what they deliver,” Heller said.
“There are so many products on the market that make health claims that the FTC and FDA cannot keep up with them all,” she explained. “Much of the ’scientific evidence’ upon which these claims are based is either non-existent, wrongly interpreted or are funded the manufacturers of the products.”
For example, said Heller, “in some cases the amount of a substance used in clinical studies that may have shown a slight change in weight or fat burning can be 5-20 times the amount in these beverages. You would have to drink 10 bottles or more a day to get even close to those amounts.”
To add credibility to their claims, these companies “like to throw around terms like ‘thermogenesis,’” said Heller. “Thermogenesis means your body’s metabolism revs up for a while and produces heat. The process of thermogenesis takes place every time you eat. The theory is that some products will increase thermogenesis for a long period of time so you burn more calories and fat and will lose more weight. As of now there is not enough scientific evidence to support these claims.”
