More research needed, still these scientists may be on to a contributing factor in weight control…
Microorganisms in the human gastrointestinal tract form an intricate, living fabric made up of some 500 to 1000 distinct bacterial species, (in addition to other microbes). Recently, researchers have begun to untangle the subtle role these diverse life forms play in maintaining health and regulating weight….
Research conducted by the authors and others has demonstrated that hydrogen-consuming methanogens appear in greater abundance in obese as opposed to normal weight individuals. Further, the Firmicutes — a form of acetogen — also seem to be linked with obesity. Following fermentation, SCFAs persist in the colon. Greater concentration of SCFAs, especially propionate, were observed in fecal samples from obese as opposed to normal weight children. (SCFAs also behave as signaling molecules, triggering the expression of leptin, which acts as an appetite suppressor.)
While it now seems clear that certain microbial populations help the body process otherwise indigestible carbohydrates and proteins, leading to greater energy extraction and associated weight gain, experimental results have shown some inconsistency. For example, while a number of studies have indicated a greater prevalence of Bacteroidetes in lean individuals and have linked the prevalence of Firmicutes with obesity, the authors stress that many questions remain.
Alterations in gut microbiota are also of crucial concern for the one billion people worldwide who suffer from undernutrition. Illnesses resulting from undernutrition contribute to over half of the global fatalities in children under age 5. Those who do survive undernutrition often experience a range of serious, long-term mental and physical effects. The role of gut microbial diversity among the undernourished has yet to receive the kind of concentrated research effort applied to obesity — a disease which has reached epidemic proportions in the developed world.
Exploiting microbes affecting energy extraction may prove a useful tool for non-surgically addressing obesity as well as treating undernutrition, though more research is needed for a full understanding of regulatory mechanisms governing the delicate interplay between intestinal microbes and their human hosts….

From the Wake Forest Baptist Medical Center 12 December 2011 press release
…shedding the pounds may have some negative consequences on the overall health of older women if the weight loss is not maintained, according to a new study by researchers at Wake Forest Baptist Medical Center.
Published recently in the American Journal of Clinical Nutrition, the study showed that some older women who lose weight gain a lot of their weight back within a year. Importantly, the weight regained is mostly in the form of fat, rather than muscle.
“The body composition of some of the women was worse than before their weight loss,” said Barbara Nicklas, Ph.D., a gerontologist at the J. Paul Sticht Center on Aging and Rehabilitation at Wake Forest Baptist and principal investigator for the study. “When older women lose weight, they also lose lean mass. Most women will gain a lot of the weight back, but the majority of the weight regained is fat.”…
“Most people will regain their weight after they lose it.” Nicklas said. “Young people tend to regain weight in the proportion that they lost it. But the older women in our study did not appear to be regaining the muscle that they lost during initial weight loss in the same way.”
The long term consequences of losing muscle mass in middle aged and older women is yet unknown, but in combination with the loss in bone density known to occur as we age, the loss of muscle could increase their fall risk, among other things.
“There are certainly a lot of health benefits to weight loss, if you can keep the weight off,” Nicklas said. “For older women who lose weight, however, it is particularly important that they keep the weight off and continue to eat protein and stay physically active so that, if the weight does come back, it will be regained as muscle instead of fat.”
She cautioned that the results from this study were limited to sedentary, abdominally obese, postmenopausal women, and the findings may differ in men or in younger populations….
