Chinese researchers fed rats a high-fat diet with pu-erh tea extract at 0.5 to 4 grams per kg and found lower body and fat-pad weight plus reduced cholesterol, triglycerides and LDL. They attribute it to raised activity of lipoprotein, hepatic and hormone-sensitive lipases.

Meat Linked to Obesity
An American Journal of Clinical Nutrition study followed some 374,000 adults in nine European countries for five years and found 250 grams of meat a day tracked with about 2 kg of weight gain. Red meat, poultry and processed meat all showed positive associations.
Obesity
Mental Acumen Linked to Body Shape
Northwestern researchers analysing 8,745 postmenopausal women aged 65 to 79 found pear-shaped women, carrying fat around the hips, had more cognitive difficulty than apple-shaped women, and that each one-point rise in BMI matched a one-point drop on a 100-point memory test.

Baby's Obesity Risk: What's Mom's Influence?
ARS researcher Kartik Shankar is studying whether a mother's own overweight can permanently alter how her child regulates weight. In his rat work, pups of overweight dams weighed normally at birth but gained markedly more once given unlimited high-fat rations after weaning.

FDA_to_Review_Weight_Loss_Drugs
The FDA starts reviewing Qnexa, with lorcaserin due in September and Contrave in December. Qnexa, a phentermine-topiramate combination, cut body weight 13 to 15% in trials but had the highest dropout rate over memory and concentration problems. Lorcaserin had fewest side effects and least effect.

Childhood Obesity Could Lead to GERD, Cancer
Researchers pulled records for 690,321 patients aged 2 to 19 in an integrated health plan and found childhood obesity associated with gastroesophageal reflux disease, a link the authors say may carry risk of further conditions such as esophageal cancer.

Weight Loss Surgery: New Option for Diabetics?
A Cleveland Clinic study is testing whether stomach bypass surgery can help more people with type 2 diabetes manage blood sugar without medication. Some formerly morbidly obese patients have come off drugs, which some clinicians attribute partly to disrupted digestive hormones.

Physical Inactivity doesn't Cause Childhood Obesity
Following 202 children for seven to ten years with accelerometers, Metcalf and colleagues reported in Archives of Disease in Childhood that fatness leads to physical inactivity, while inactivity does not necessarily lead to fatness.

How the Bacteria in Your Gut is Linked to the Size of Your Waistline...
After 12 weeks of drinking fermented milk containing Lactobacillus gasseri SBT2055, subjects with obese tendencies lost an average 4.6 percent of abdominal fat and 3.3 percent of subcutaneous fat, with no significant change in controls. Mercola ties gut bacteria to body weight.

Childhood obesity on the rise in the U.S.
Seventeen percent of Americans aged 2 to 19 were obese in 2007-2008. Among 6- to 11-year-olds the rate climbed from 6.5 to 19.6 percent since around 1980, and one study found 80 percent of children overweight at ages 10 to 15 were obese by 25.

Biking/Brisk Walking Deal Blows to Obesity
A state-by-state report found adults heavier than a year earlier in more than half of states. The Harvard Nurses' Health Study, which followed over 116,000 women for 16 years, found those doing the equivalent of 30 minutes of biking or brisk walking a day held their weight or lost a few pounds.

Obesity Statistics by State are Revealed
A report by two advocacy groups finds Americans grew heavier in 28 states over the past year, with 10 of the 11 highest-obesity states in the South and Mississippi first for the sixth year running. More than a quarter of the population is obese in 38 states.

Diet Tricks That Really Work (2)
Chewing longer curbs portion size and aids digestion, Mercola writes, citing a study where people eating ice cream over 30 minutes released more hunger-regulating hormones than those who took five, another where slow eaters took in about 10 percent fewer calories.
Obesity
Diet Tricks That Really Work
Mercola passes along Live Science's list of weight-loss tactics: skip high-fructose corn syrup, treat junk food as addictive, keep meal times structured, eat a protein-rich breakfast, favour whole foods over processed, shrink your plates, and pay attention while you eat.
Obesity
Study explains why chili pepper compound leads to weight loss
Rats on high-fat diets that received capsaicin lost up to 8% of their body weight, and Daegu University researchers found the compound shifted levels of at least 20 proteins in fat tissue, which they suggest is part of how it works.

Obesity boosts cancer risk big time
Reviewing the epidemiological evidence in Proceedings of the Nutrition Society, Oxford's T.J. Key reports each 10 kg/m2 rise in body mass index goes with higher risks of esophageal, colon, breast, endometrial and kidney cancer. The editor cautions the link may not be causal.

Too lazy or too busy to exercise? No problem!
Randall Johnson's team knocked out the gene for the enzyme FIH in mice, and the animals stayed thin and healthy even on a high-fat diet, while hyperventilating and drinking more than usual. The researchers suggest a drug might one day suppress the gene to raise metabolism.

Cutting Fat--and Calories--from Cakes and Frostings
ARS scientist Mukti Singh is building cake mixes and frostings around Fantesk, trans-fat-free oil droplets encapsulated in cornstarch or wheat flour. Cakes made with it need no added oil and have better texture and more volume; the frostings spread like buttercream with up to 50 percent less fat.
