Raspberry Ketones are creating quite a buzz in the supplement world. After Dr. Oz promoted them on his television show, the products have been flying off the shelves. Media outlets have reported on ‘ketone craze’ as people looking to drop weight quickly buy bottle after bottle.

Ketones and Weight Loss

“When a body is starving for sugar, ketones take over and help breakdown the next best source of energy: stored fat,” International Business News explains. “The body produces ketones during starvation or fasting and also during long bouts of physical training.” Simple put, raspberry ketones can make the body release fat from fat cells.

“I never understood how powerful it could be,” Oz said on a recent episode of his show.

The supplement has been touted as a “miracle for those struggling with weight loss.”

Not all positive reviews

Raspberry Ketone users have had positive feedback, but doctors say the supplement is not a quick fix to years of unhealthy dieting and lack of exercise.

“People are willing to take chances. It’s amazing how many people look for a miracle instead of looking at what they’re eating and how much they’re moving and fixing whatever is broken,” Mary Hartley, a registered dietitian and clinical nutritionist in Brooklyn, N.Y. told ABC News.

“There is no magic bullet for weight loss,” said registered dietitian Joan Salge Blake, a clinical associate professor at Boston University. “People are spending billions of dollars on the next miracle pill or patch or cream. One of the best-kept secrets, depending on your health insurance and medical condition, is you could possibly be a co-pay away … from sitting down with a nutrition expert and having that person map out a healthy weight-loss plan that is going to not only take it off, but keep it off.”
