In a study conducted by Barbara Rolls, Ph.D., a professor at Penn State University and co-author of The Volumetrics Weight-Control Plan (HarperTorch, 2003), subjects who ate vegetables as part of their meals consumed about 100 fewer calories and didn't make up for the caloric deficit later. While saving 100 calories a day may not sound like much, it translates into losing 10 pounds in one year. Use just this one trick — and there goes your tummy!
Unintentional weight loss can occur because of an inadequately nutritious diet relative to a person's energy needs (generally called malnutrition). Disease processes, changes in metabolism, hormonal changes, medications or other treatments, disease- or treatment-related dietary changes, or reduced appetite associated with a disease or treatment can also cause unintentional weight loss. Poor nutrient utilization can lead to weight loss, and can be caused by fistulae in the gastrointestinal tract, diarrhea, drug-nutrient interaction, enzyme depletion and muscle atrophy.
It's truly disturbing when doctors come up with seemingly fad diets that could prove dangerous, but that appears to be happening all the time and most of them are also pretty successful. The latest to join the trend is an American doctor who is providing a drastic and quick weight-loss method, the K-E Diet. It involves putting food into your body through the nose, using a dripping tube.
