I Think, Therefore I Am

1 Think Yourself Thin, Says Study

Can you think yourself thin? If you convince yourself that the low-cal food you eat is indulgent and caloric, it may lower your levels of the hunger hormone ghrelin, finds a new Yale U study. Ghrelin levels spike half an hour before mealtimes after which they return to normal. For the study, two groups of volunteers were given the same 380-calorie milkshake. One was told it was a high calorie treat; the other was told it was a new low-calorie concoction. Researchers measured ghrelin levels before and after consumption of the shakes and found that volunteers who thought they had indulged in a decadent dessert had much lower ghrelin levels than those who were told they had just drunk a healthy snack. Researchers suggest that merely thinking you’ve indulged may curb overeating.

False Positives Lead to Surgery

2 Ovarian Cancer Screening May Not Save Lives

Ovarian cancer screenings, consisting of blood tests and ultrasounds, didn't save lives, say researchers who note that the screenings may also lead to unnecessary surgery and complications. The research, published in Journal of the American Medical Association, found that women who were screened each year for ovarian cancer were just as likely to die from the disease compared with women who didn't have the screenings. The large study also revealed that more of the women who were screened annually had their ovaries removed and suffered complications due to false-positive screening results. MSNBC reports that this study was part of a larger trial examining the effectiveness of screening for cancers, including prostate, lung and colorectal.

Shrink Belly, Protect Brain

3 Gastric Bypass May Lower Alzheimer’s Risk

Results from a new study suggest that gastric bypass surgery may do more for obese diabetics than just shrink their waistlines. A follow-up of 15 obese type 2 diabetics who had weight-loss surgery six months before found the expression of genes linked to the amyloid precursor that accumulates as toxic plaques in the brains of Alzheimer’s patients decreased by 22 percent after surgery in addition to losing an average of 86 pounds. Previous research has convinced many scientists that obesity and diabetes increase the chance of developing Alzheimer’s, likely due to obesity’s pro-inflammatory effect on the brain and the rest of the body. Even though weight loss may reduce the risk, weight loss in the elderly can be an initial symptom of dementia.
