losing 10 pounds could boost your immunity

excess fat around the abs can turn the body's defense system against you, leading to heart and other diseases. australian researchers found that for obese individuals, shedding just 10 pounds could straighten out an off-balance immune system. the immune system is made up of many different kinds of cells that protect the body from germs, viruses and other invaders. these cells need to co-exist in a certain balance for good health to be maintained. many factors, including diet and excess body fat, can tip this balance, creating immune cells that can harm, rather than protect, our bodies. scientists have known for some time that excess body fat, particularly abdominal fat, triggers the production of so-called "pro-inflammatory" immune cells, which circulate in the blood and promote inflammation in our bodies. such chronic inflammation has been linked with coronary artery disease and other health problems. in addition, other inflammatory immune cells, known as macrophages, are also turned on within fat tissue. story continues below ↓ advertisement | your ad here dap('&pg=nbcmsh&ap=1089','300','250'); the study looked at obese people with type 2 diabetes or prediabetes who were limited to a diet of between 1,000 and 1,600 calories a day for 24 weeks. (prediabetes is a condition in which people have high glucose levels, but not high enough to be considered full-blown diabetes). gastric banding — a procedure in which a band is placed around the upper part of the stomach so that it can only hold a small amount of food — was performed at 12 weeks to help restrict food intake further. the results show an 80 percent reduction in the number of pro-inflammatory immune cells, as well as decreased activation of macrophages in the participants' fat tissues. "excess weight disorders now affect 50 percent of adult australians, with obesity being the major cause of type 2 diabetes and some cancers," said study researcher katherine samaras, a professor at the garvan institute of medical research in sydney. in the united states, one-third of the population is considered obese. "the situation has reached crisis point, and people must be made aware that excess fat will affect their immune systems and therefore their survival," samaras said. a weight loss of about 13 pounds was enough to bring the levels of pro-inflammatory cells down to that found in lean people, according to samaras. the scientists could also predict about how much weight people would lose after surgery based on how active the immune cells in their fat were. "it’s the first time this has been described, and is important because it helps us understand why some people lose weight more easily than others, and that inflammation is involved in regulating the response to [gastric banding] surgery," samaras said. more work is needed to tease the exact role of these immune cells in obesity and type 2 diabetes, the researchers say. the results were published april 7 in the journal of clinical endocrinology metabolism. also in msnbc.com health insurer targeted breast cancer patients to cancel paralyzed mom of triplets seeks to see her kids tobacco ‘mints’ tied to poisoning in kids | poll nyt: in some adoptions, love doesn't conquer all is your boyfriend making you fat?

a university of missouri researcher has found that eating a healthy breakfast, especially one high in protein, increases satiety and reduces hunger throughout the day. in addition, using functional magnetic resonance imaging (fmri), the researchers found that eating a protein-rich breakfast reduces the brain signals controlling food motivation and reward-driven eating behavior. “everyone knows that eating breakfast is important, but many people still don’t make it a priority,” said heather leidy, assistant professor in the mu department of nutrition and exercise physiology.

consuming too many calories may disturb the pathway in the brain that directly affects food intake and body weight, according to a new study. researchers from the university of wisconsin-madison report that the too much food or energy consumption leads to a problem called metabolic inflammation, according to findings from the mice studies. "metabolic inflammation is a chronic, low-grade condition consisting of inflammatory-like responses at the molecular level.

overweight and obesity are known to dramatically increase the risk of developing heart disease, diabetes, cancer and dementia. excess body fat fuels the fire of systemic inflammation and the release of dangerous chemical messengers or cytokines that damage the delicate inner lining of our arteries; this sets the stage for vascular dysfunction. as we pass age 35, there is a natural tendency to gain weight due to slowing metabolism, unchanged calorie intake and less physical activity.

if you ever feel tempted to go for a cheeseburger, fries and a soft drink, consider this: along with the fast food, you are ordering up an increased risk of heart disease, diabetes and obesity. but the opposite is true, too. according to a new university of florida (uf) study, if you stay away from processed and fast foods and instead eat a lot of veggies, nuts and fruits, you will actively be helping to prevent or reverse harmful metabolic processes in your body.
