More Information and Recent Research on Obesity and Weight Loss

(UPI) More than 7-out-10 U.S. adults would rather keep their current debt, than gain 25 pounds and be completely debt free, a survey indicates. The survey of 2,021 U.S. adults for Credit Karma, a personal finance company, found weight trumped debt for many U.S. adults this summer.
(Art Markman, Ph.D., Psychology Today) There is a tendency to look at people who have put on weight and assume that there is something about their personality that made them gain weight. We rarely contemplate the opposite possibility, though. Perhaps behaviors that lead people to gain weight actually lead to changes in people’s personality over time.
(Faith Brynie, Ph.D., Psychology Today) [Researchers] have discovered that a particular lipid messenger in the gut, known as oleoylethanolamine (OEA), controls the brain’s perception of reward value when it comes to food. The researchers studied two groups of mice—one fed a high-fat diet and another fed a low-fat diet. They found that the high-fat group had unusually low levels of OEA in their intestines. Additionally, in response to fat, the brains of mice on high-fat diets didn’t release as much dopamine, the neurotransmitter associated with reward, compared to mice on low-fat diets. Thus high-fat diets can disrupt communication between the gut and the brain.
An infusion of OEA into the mice that were fed high-fat diets seemed to restore the rodents’ dopamine-based reward response. It even led the mice to choose more low-fat foods when given the option. Based on these findings, the researchers suggest that OEA signaling in the gut may help limit the consumption of high-fat foods through its effects on the dopamine-based reward circuit in the brain.
(Scientific American) Your mother was right: breakfast is the most important meal of the day—especially if you're looking to lose weight. And the bigger the better, according to a new study… The study included 93 overweight or obese women. Half the women ate 700-calorie breakfasts, 500-calorie lunches and 200-calorie dinners. The other reversed it, with a 200-calorie breakfast, the same 500-calorie lunch and a 700-calorie dinner. After three months, those eating the jumbo breakfasts lost an average of 17.8 pounds and three inches from their waistlines—10 pounds and an inch-and-a-half more than the group having skimpy breakfasts and big dinners.
(Appetite for Health) Starting your day with a bowl of oatmeal is one of the best ways to improve your heart’s health, but it may also be a great way to start your day to help manage your hunger to help keep your calories in check, which may help you whittle your waistline.
(Sharecare.com) Got a belly bulge that won't budge? A pooch that won't vamoose? Are all the drop-5-pounds-fast tricks that used to work for you increasingly useless? Blame the shifting hormones and slowing metabolism that come with extra birthday candles. They have a way of rewriting the rules of weight loss after 40. Here's how to fix that: rising blood sugar… The fix: Cut the carbs and stop the madness… sleep problems… The fix: yoga… disappearing muscle… The fix: strength training.

A Food Psychologist's Take on the Paleo Diet
(Mary E. Pritchard, Ph.D., Psychology Today) Are we obese because of our Modern Diet? To some extent, yes. Would we benefit from the Paleo Diet? Initially, yes – it would be getting us away from all of that processed food and back to whole foods like lean protein, fruits, and veggies. That being said, the Paleo Diet does not meet all of our modern nutritional needs.
(David L. Katz, MD, MPH, FACPM, FACP, Yale  Prevention Research Center) My impression – based in part on 20 years of clinical experience – is that feeding a sweet tooth with sweetness from any source helps it grow into a sweet fang, much inclined to take over your appetite and your life.
(MedPage Today) The vitamin D receptor -- not the vitamin itself -- may inhibit a process that turns adipocytes into "brown" or metabolically active fat, researchers found. In a series of experiments with human fat cells, VDR inhibited the expression of a key mediator of energy metabolism… "These data support pursuing the therapeutic strategy of developing factors that specifically target releasing the beige fat expression profile of human cells," [the researchers] wrote.
(MedPage Today) Bariatric surgery, known for its often striking metabolic effects including mitigation of nonalcoholic fatty liver disease, changes the expression of genes in the liver, researchers found. In a small study that looked at liver biopsies from NAFLD patients before and after bariatric surgery, methylation changes associated with the disease phenotype were partially reversible, Jochen Hampe, PhD, … and colleagues reported… "Our findings provide an example of treatment-induced epigenetic organ remodeling in humans," they wrote.
Community: Once again, researchers report a beneficial effect of the food restriction and weight loss associated with bariatric surgery as a benefit of the surgery itself. Sorry, I don’t buy it. We can restrict calories without incurring the dangers of surgery.
(University of Cambridge) Chronic cocaine use may reduce the body's ability to store fat, new research from the University of Cambridge suggests. The scientists found that cocaine use may cause profound metabolic changes which can result in dramatic weight gain during recovery, a distressing phenomenon that can lead to relapse.
