It’s often said that good health begins in the gut, an aphorism that is well supported by two studies published in the August 29 issue of Nature (2013; 500, 541-46). In short, individuals with low bacterial richness in their gut have more obesity and inflammation--and weight loss can improve the richness of their bacterial genes.
It seems that debit card purchases promote the same type of frivolity in children as in adults, but when cards are swiped to pay for school lunches, the impact goes deeper than just free spending. Kids’ food choices also become foolish, according to a study that appeared in the January issue of Obesity (2014; 22 , 24–26).
Here is another reason to encourage children to maintain a healthy weight: According to a Kaiser Permanente Southern California study, children who are overweight or obese are at significant risk for developing hyper- tension.
Preadolescence is a time of major change and growth, bringing psychological, physical and social shifts for boys and girls alike. Caught between the carefree days of childhood and the first throes of being a teenager, “tweens” (roughly aged 9–12) are a force to be reckoned with. Like many other populations, preadolescents are suffering from lack of exercise, which threatens to chart a course toward obesity and disease.
It is well known that the United States faces a childhood obesity epidemic. In fact, 81% of respondents in a poll on the topic considered childhood obesity a serious concern and two-thirds believed the problem was getting worse (Hassink, Hill & Biddinger 2011). Actually, national surveys show a stabilization of childhood obesity rates and even small declines in some localities (RWJF 2012).
In his research paper, Hill notes that body weight and obesity are increasing in all segments of the population in most, if not all, countries around the world. Further, although most people are aware that
a sedentary existence, combined with overeating, has negative health consequences, many are not able to make and sustain the changes to combat this way of life. Moreover, most people who do achieve weight loss goals regain the weight over time. Is it inevitable that our society will eventually be obese?
How many times have you trained a client who couldn’t lose weight no matter how hard you trained him or how “clean” he insisted his nutrition was? It’s frustrating for both fitness professional and client when the waistline doesn’t budge in spite of what seems enough effort. However, the reason belly fat can be so intractable is that it’s as much a hormonal phenomenon as it is a caloric one. In order to understand how to get rid of belly fat, it’s important to factor hormonal physiology into the overall equation.
Researchers have established that obesity is associated with increased mortality risk. However, a new study suggests that the severity of this risk may have been underestimated.
Published in Population Health Metrics (2014; doi:10.1186/1478-7954-12-6), the study looked at mortality and body mass index in nonsmoking adults aged 50–84. Data was pulled from the National Health and Nutrition Examination Surveys (1988–1994 and 1999–2004) and linked to the National Death Index through 2006.
Weight problems may be all in your head—or at least in your brain, according to an emerging body of brain-imaging work and related research on cravings, overeating and addictive responses to food. Daniel Amen, MD, one of the world’s best-known neuropsychiatrists, has worked with tens of thousands of patients from 90 countries for more than 20 years and has recently gathered results and insights related to the brain-fat connection in his best-selling book, The Amen Solution: The Brain Healthy Way to Lose Weight and Keep It Off (Crown 2011).
