Since he revealed his re-svelte body on “Good Morning America” this week, “Fit2Fat2Fit” fitness trainer Drew Manning has sparked both inspiration and controversy about the lessons to be learned from his experiment. Readers on CNN were quick to participate in the conversation.
Manning, who lost 70 pounds just 6 months after he purposely gained it, has drawn praise from some. They said the strategy shows his desire to grow in understanding his clients’ weight loss struggles:

Having a large waist is an important early warning sign for diabetes, one that in some cases may be just as significant as body mass index (BMI), if not more so, a new study has found.
Waist size, which provides a rough measure of a person's body type, may be especially useful for identifying high-risk people who are overweight but not obese, the study suggests. Obesity is a clear-cut risk factor for diabetes, but doctors generally have a harder time determining which overweight people are most vulnerable to the condition.
"Waist circumference is very helpful in people who are obese, but exceptionally helpful in people who are overweight," says Dr. Abraham Thomas, M.D., head of endocrinology and diabetes at Henry Ford Hospital, in Detroit. Thomas was not involved in the study.

You might want to lose weight, but the noticeable benefits seem so far off in the future that you continually procrastinate. You need a reason to get more fit right now - how about money?
A new study in the journal Archives of Internal Medicine reinforces this idea that if money were on the line, you might start on a healthier path. Web and mobile tools are cropping up to help you do this yourself - but first, a word about the study.

Five years ago, California passed some of the strongest school-food legislation in the nation in hopes of combating childhood obesity.
These rules limit the kinds of unhealthy foods that students can buy in vending machines or at a snack bar, which aren’t offered as part of lunch in the school's cafeteria.
The state is well-known for leading the nation with health trends, so it's no surprise that its legislators are out front when it comes to cutting back on junk food in schools. A new study shows their efforts may be working: High school students in California are eating fewer calories and less added sugar and fat during the school day than students from other states.

Sweet tooth? You’re not alone. Sugary foods and beverages are delicious. But we’ve also learned they can be highly addictive and, too much of them, can take a serious toll on our health.
Today some of our favorite drinks, gum, baked goods, and candy are available in sugar-free versions. But that got me thinking... are sugar substitutes any better for you than the real thing? I was not alone on this issue. I’ve received dozens of tweets and emails wondering if fake sugar can harm us, or worse, crave more food!
For some answers I turned to internist and physician nutrition specialist, Dr. Melina Jampolis. Her specialty is practiced by only 200 physicians in the United States. She focuses exclusively on nutrition for weight loss and disease prevention and treatment.

Brides often feel the pressure of looking their best on their wedding day, purchasing a dress with sometimes significantly lower wedding weight in mind. While some try to lose weight the healthy way focusing on long-term weight management, eating right and exercise, others attempt crash diets sometimes going to extreme measures to shed those extra pounds.
One such bride, Jessica Schnaider told ABC and The New York Times that she wanted to lose 10 pounds before her big day. She went to Dr. Oliver Di Pietro in Miami Beach, Florida. In a release to CNN, Di Pietro says he's brought the K-E diet to the United States from Italy. The diet involves inserting a feeding tube into a patient's nose that runs to the stomach for a period of 10 days.

Work can be a real burden for some people. They feel overwhelmingly exhausted and cynical toward their workplace environment, and believe their efforts are not valued.
In other words, they are burned out.
A new study in the American Journal of Clinical Nutrition connects these sentiments with overeating and controlled eating behaviors.
The experiment involved 230 working women. Those who were experiencing workplace burnout at the beginning of the experiment were more likely to have emotional and uncontrolled eating than those without burnout. This held true even after 12 months.
Among those without burnout, uncontrolled eating decreased significantly over the year.

On Wednesday morning, an advisory committee for the Food and Drug Administration recommended that the FDA approve Qnexa, a weight-loss drug that works to suppress appetite. The panel voted 20-to-2 in favor of approval.
The FDA has until April 17 to decide whether to take the committee's recommendation. If they do so, it will be the first time the FDA has approved a weight-loss drug since 1999.
The advisors' decision was a reversal of a previous recommendation in 2010. At the time, a panel rejected Qnexa based on concerns about increased heart rates, psychiatric problems and birth defects in patients taking the pills.
Dr. Sanjay Gupta explains what this means and what's next in the video above.

How many times have you been to the movie theater, ordered a regular-sized popcorn or soda and been asked, “Would you like a large for a quarter more?” What about ordering a sandwich at your local deli? "Make it a combo!" you probably say.
We’re trained early on, oftentimes by our parents, to clean our plates or no dessert. Frequently, regardless of how hungry we are, that’s exactly what we’ll do.
Sure, the medium-sized popcorn would’ve been entirely satisfying, but if offered the larger portion, we’re going to take it and eat it – all of it.
This phenomenon, in part, is was what sparked a series of studies conducted at a fast-food Chinese restaurant on Tulane’s New Orleans campus.
The researchers conclude, in a study published in this month’s Health Affairs, that up to one-third of customers accepted a verbal offer to downsize their lunch, regardless of whether they were offered a minor monetary incentive to do so. Customers who accepted the downsized meals ate, on average, 200 fewer calories than did those who ordered the full-sized meals.

Professional football players already vulnerable to memory loss and cognitive problems stemming from repetitive head injuries may be at even greater risk if they also carry excess weight, as many of them do.
In a small new study of retired NFL players, researchers found that overweight players had less blood flow to key areas of the brain and lower scores on mental-function tests than former players of normal weight.
"There was a very significant relationship: As their weight went up, their reasoning scores and memory and attention scores went down," says the senior study author, Daniel G. Amen, M.D., founder and medical director of Amen Clinics, a neuropsychiatry clinic and research center based in Newport Beach, California.
