SIX years after dropping an average of 129 pounds on the TV program “The Biggest Loser,” a new study reports, the participants were burning about 500 fewer calories a day than other people their age and size. This helps explain why they had regained 70 percent of their lost weight since the show’s finale. The diet industry reacted defensively, arguing that the participants had lost weight too fast or ate the wrong kinds of food — that diets do work, if you pick the right one.

Sweden has become the first Western nation to develop national dietary guidelines that reject the popular low-fat diet dogma in favor of low-carb high-fat nutrition advice. The switch in dietary advice followed the publication of a two-year study by the independent Swedish Council on Health Technology Assessment. The committee reviewed 16,000 studies published through May 31, 2013. The expert committee consisted of ten physicians, and several of them were skeptics to low-carbohydrate diets at...

Contestants lost hundreds of pounds during Season 8, but gained them back. A study of their struggles helps explain why so many people fail to keep off the weight they lose.

The long read: In 1972, a British scientist sounded the alarm that sugar – and not fat – was the greatest danger to our health. But his findings were ridiculed and his reputation ruined. How did the world’s top nutrition scientists get it so wrong for so long?

You eat too much, and so you get fat. We all know that. It's not rocket science. Except it's not actually as simple as that.

If you want to lose weight, a new diet or gym membership sounds a whole lot better than consuming someone else's poop in pill form, but that's exactly the method researchers are about to investigate in a clinical trial that's been approved for...

If you want to lose weight, a new diet or gym membership sounds a whole lot better than consuming someone else's poop in pill form, but that's exactly the method researchers are about to investigate in a clinical trial that's been approved for later this year. It's not the most pleasant treatment you can imagine, but there's strong evidence that faeces is good for the microbiome environment inside our guts. Reports have shown that in some situations...

Diet guidelines recommend increasing dietary diversity. Yet, metrics for dietary diversity have neither been well-defined nor evaluated for impact on metabolic health.

Healthy-eating plans of the future may be tailored to your own gut bacteria. 

Before driving cross-country a few weeks ago, I happened to see that Amazon now offers free audio narration with many of their Kindle books that are part of their Kindle Unlimited program.  The first book I tried out was simply mind-blowing—Dr. Margaret Cuomo’s 2012 book, A World Without Cancer. Dr. Cuomo is a radiologist, and sister of New York Governor Andrew Cuomo.

A new study finds that people today who eat and exercise the same amount as people 30 years ago are still fatter.

Three years ago, life caught up with the novelist Pat Conroy. After decades of eating and drinking pretty much whatever he wanted, the best-selling novelist found himself lying in a hospital bed, bloated with fluids as his organs floundered. He had Type 2 diabetes, high blood pressure and a failing liver.

People can’t get enough information about artificial sweeteners. Do they help you diet? Do they make you fat? Are they healthier than sugar? Are they healthy?

Ever fantasize of being able to see the benefits of exercise without having to, you know, work out? If so, research from Britain's University of Southampton published this week gives a glimpse of what may be possible in the future. Ali Tavassoli, a professor of chemical biology, and Felino Cagampang, an associate professor in integrative physiology, reported that they had synthesized a molecule that acts as an "exercise mimic" by tricking cells into thinking they have run out of energy.

Cosmetic surgery after weight loss is a personal choice. You will need to research the types of cosmetic surgery available and discuss the pros & cons

The biggest features of a Western diet are overconsumption of over-refined sugars, highly refined and saturated fats, animal protein and a reduced intake of plant-based fibers. This translates to a diet high in fat, red meat, salt and sugars, and low in fiber - but what impact can this diet have on your health?

A group of respected physicians has stepped forward to challenge the common assertion that obesity can be easily fixed by diet and exercise. For most of the nation's 79 million adults and 13 million kids who are obese, the "eat less, move more" treatment, as currently practiced, is a prescription for failure, these doctors say. In a commentary published Thursday in the journal Lancet Diabetes and Endocrinology, four weight-loss specialists set out to correct what they view...

Oz was harshly criticized at a Senate consumer protection hearing that followed up on the Federal Trade Commission’s $34 million January lawsuit targeting companies that sell bogus diet products.
