For example, fat “cushions” the release of various flavors on the tongue, unveiling them gradually and allowing them to linger. When fat is removed, flavors tend to immediately inundate the tongue and then quickly flee, which we register as a much less satisfying experience. Fona’s experts can reproduce the “temporal profile” of the flavors in fattier foods by adding edible compounds derived from plants that slow the release of flavor molecules; by replacing the flavors with similarly flavored compounds that come on and leave more slowly; or by enlisting “phantom aromas” that create the sensation of certain tastes even when those tastes are not present on the tongue. (For example, the smell of vanilla can essentially mask reductions in sugar of up to 25 percent.) One triumph of this sort of engineering is the modern protein drink, a staple of many successful weight-loss programs and a favorite of those trying to build muscle. “Seven years ago they were unpalatable,” Sobel said. “Today we can mask the astringent flavors and eggy aromas by adding natural ingredients.”
The number of obese Americans ages 65 and older will increase from 10.3 million to 14.3 million by 2010, averaging 400,000 new obese adults per year (Arteburn, Crane, & Sullivan, 2004). Today, more than 65% of adults in the United States are overweight or obese. Obesity puts people at risk for heart disease, type 2 diabetes, high blood pressure, stroke, and some types of cancer.
I finally hit the sweet spot just a few weeks later, in Chicago, with a delicious blueberry-pomegranate smoothie that rang in at a relatively modest 220 calories. It cost $3 and took only seconds to make. Best of all, I’ll be able to get this concoction just about anywhere. Thanks, McDonald’s!
Scientific research has shown that increasing low intensity exercise produces a very low risk of injury to the heart of muscle skeletal system. A light- to moderate–intensity activity, such as 5 to 15 minutes of walking per session, 2 to 3 times a week.
Putting on excess weight is very common for a number of reasons that we’ll explain. But it’s not an inevitable part of the aging process, and it could put your health at risk. If you understand why you tend to gain weight more easily as you get older, you can do something about it. And doing something about it is what this book is all about.

Excess of subcutaneous fat in proportion to lean body mass. Excess fat accumulation is associated with increase in size (hypertrophy) as well as number (hyperplasia) of adipose tissue cells. Obesity is variously defined in terms of absolute weight, weight:height ratio, distribution of subcutaneous fat, and societal and esthetic norms. Although faulty eating habits related to failure of normal satiety feedback mechanisms may be responsible for some cases, many obese people neither consume more calories nor eat different proportions of foodstuffs than nonobese people. Contrary to popular belief, obesity is not caused by disorders of pituitary, thyroid, or suprarenal gland metabolism. However, it is often associated with hyperinsulinism and relative insulin resistance. Studies of obese twins strongly suggest the presence of genetic influences on resting metabolic rate, feeding behavior, changes in energy expenditures in response to overfeeding, lipoprotein lipase activity, and basal rate of lipolysis. Environmental factors associated with obesity include socioeconomic status, race, geographic region of residence, season, urban, or rural residence, and being a member of a smaller family. Prevalence is greater when weight is measured during winter rather than summer; is much more common in the southeastern U.S., although northeastern and midwestern states also have high rates, a phenomenon independent of race, population density, and season.
Obesity is associated with a modest risk for developing rheumatoid arthritis (RA). Given the rapidly increasing prevalence of obesity, this has a significant impact on RA incidence and may account for much of the recent increase in the incidence of RA.A
Gordon’s team then repeated the experiment with one small twist: after giving the baby mice microbes from their respective twins, they moved the animals into a shared cage. This time both groups remained lean. Studies showed that the mice carrying microbes from the obese human had picked up some of their lean roommates’ gut bacteria—especially varieties of Bacteroidetes—probably by consuming their feces, a typical, if unappealing, mouse behavior. To further prove the point, the researchers transferred 54 varieties of bacteria from some lean mice to those with the obese-type community of germs and found that the animals that had been destined to become obese developed a healthy weight instead. Transferring just 39 strains did not do the trick. “Taken together, these experiments provide pretty compelling proof that there is a cause-and-effect relationship and that it was possible to prevent the development of obesity,” Gordon says.
