Bottle-Fed Babies At Higher Obesity Risk

Author: Oksana Aron, MD Source: Weight Loss NYC Jun 26, 2009

A new international study published in the American Journal of Clinical Nutrition claims that breast milk has less protein than formula.

Bottle-fed babies have been believed to be larger and store more fat, making them more susceptible to childhood obesity, and the new study is calling for protein levels in baby formula to drop.

To reach the conclusion, a third were given a low protein content formula milk, a third had a formula with a higher level of protein, while the rest were breast-fed during their first year.

In order to qualify as breast-fed, kids had to be either exclusively given breast milk, or have a maximum of three bottles per week.

Then the infants were followed up to the age of two with regular weight, height and body mass index measurements taken.

At the age of two, there was no difference in height between the groups, but the high protein group were the heaviest.

The researchers suggest lower protein intakes in infancy might protect against later obesity.


The study, which highlights the importance of breast-feeding as well as further research in infant formula composition, will continue to see if the children given lower protein formulas have lesser risks of obesity later in life. —Newspost Online

The Brain's Memories of Fat

According to a recent study by the University of California, Irvine, the human brain forms long-term memories of eating fatty foods, demonstrating a link between dietary fats and appetite control.

Earlier studies found that oleic acids from fats are turned into a compound called oleoylethanolamide (OEA) in the upper small intestines, and send hunger-curbing messages to the brain to help increase feelings of fullnes. The new study discovered that OEA also turns superficial, short-term memories into meaningful, long-term memories by activating memory signals in the amygdala, which is responsible for storing emotional events.

"OEA is part of the molecular glue that makes memories stick," neuroscientist Daniele Piomelli, a co-author of the study, said in a university news release. "By helping mammals remember where and when they have eaten a fatty meal, OEA's memory-enhancing activity seems to have been an important evolutionary tool for early humans and other mammals." —MedicineNet

Researchers Find Brain Connection to Cravings

Researchers at California Institute of Technology found in their latest study on cravings that there are two areas in the brain that give people self-control over unhealthy foods.

Using an MRI to scan volunteers' brains while looking at images of different types of food to decide which ones they would prefer to eat, researchers discovered significant differences in brain activity between those with self-control over what they eat and those without it.

...the ventromedial prefrontal cortex (vmPFC) is involved in all value-based decisions. When vmPFC activity decreases, a person will probably reject an item, whereas increased activity means they'll probably choose it.

The new study found that in people with no self-control, the vmPFC seemed to take into consideration only the taste of a food.

"In the case of good self-controllers, however, another area of the brain -- called the dorsolateral prefrontal cortex (DLPFC) -- becomes active and modulates the basic value signals so that the self-controllers can also incorporate health considerations into their decisions," principal investigator Antonio Rangel, an associate professor of economics, said in a CalTech news release. —HealthDay News

Curcumin May Prevent Obesity

curcumin
Curcumin is the principal curcuminoid of the popular Indian curry spice turmeric, which is a member of the ginger family


Findings from a study at Tufts University suggests dietary curcumin may have a potential benefit in preventing obesity. Angiogenesis is necessary for the growth of adipose tissue. Dietary polyphenols may suppress growth of adipose tissue through their antiangiogenic activity and by modulating adipocyte metabolism. In addition, curcumin significantly lowered serum cholesterol and expression of PPAR-gamma and CCAAT/enhancer binding protein alpha, 2 key transcription factors in adipogenesis and lipogenesis. The curcumin suppression of angiogenesis in adipose tissue together with its effect on lipid metabolism in adipocytes may contribute to lower body fat and body weight gain. — Journal of Nutrition

Association between Obesity and Colon Cancer

Researchers from Michigan State University and Oakland University in Rochester, MI, discovered how leptin, a fat cell-derived hormone, may aid in the progression of colon cancer….The results appear in a paper called Novel Mechanism for Obesity-induced Colon Cancer Progression published in Carcinogenesis….Cells from the mice that carried the Apc mutation when stimulated with leptin produced significantly more vascular endothelial growth factor (VEGF) than the cells from the other mouse model, according to the investigators….These cells also had higher HUVEC cell proliferation, chemotaxis, upregulation of adhesion proteins, and cell-signaling activation resulting in nuclear factor kappa B nuclear translocation and DNA binding due to VEGF…. — GEN News

FDA warns against non prescription weight loss pills

Author: Oksana Aron, MD Source: Weight Loss NYC
The FDA is warning people against taking 28 types of weight loss pills. The tainted products contain potentially dangerous undeclared ingredients, the Food and Drug Administration found, including prescription drugs in levels much higher than the maximum recommended dosage:

The brands are Fatloss Slimming, 2 Day Diet, 3x Slimming Power, Japan Lingzhi 24 Hours Diet, 5x Imelda Perfect Slimming, 3 Day Diet, 7 Day Herbal Slim, 8 Factor Diet, 7 Diet Day/Night Formula, 999 Fitness Essence, Extrim Plus, GMP, Imelda Perfect Slim, Lida DaiDaihua, Miaozi Slim Capsules, Perfect Slim, Perfect Slim 5x, Phyto Shape, ProSlim Plus, Royal Slimming Formula, Slim 3 in 1, Slim Express 360, Slimtech, Somotrim, Superslim, TripleSlim, Zhen de Shou and Venom Hyperdrive 3.0.

Many of the products are marketed as "dietary supplements" and claim to be "natural" or contain only "herbal" ingredients. But the FDA said some of the pills include sibutramine, a controlled substance; rimonabant, a drug not approved for marketing in the U.S.; phenytoin, an anti-seizure medication; and phenolphthalein, a suspected carcinogen.

Many of these products contain medication or chemicals that may raise your blood pressure in the very list and may kill you at the most. Even more a lot of these products (maybe all) have no scientific bases that they actually work.
All the medications that we dispense at our Medical weight loss center are FDA [government] approved and fully endorsed by the American Society of Bariatric Physicians and the American Board of Bariatric Medicine.

The Best and the Worst Choices in Food

Author: Oksana Aron, MD Source: Weight Loss NYC
Nutrition Action named their best selections for what they consider the healthiest and worst options in food choices. They named some bad choices like “Starbucks on Steroids,” “Artery Crust” and “Angioplasta.” It never ceases to amaze me how food manufacturers can make such ordinary food so bad for you. The calories, fats, carbs and sodium are real killers to any diet plan.

View some of our suggested recipes for success, and find healthy calorie food items on our New York Weight Loss Center website.
