FAULTY “BRAIN SWITCH” DETERMINES OBESITY Obesity is considered as a disease in this New World. It has become a pandemic affecting every Nation. According to data collected in 2014 from the World Health Organization, more than 600 million adults around the world are obese and 41 million children younger than 5 years old are overweight. This in turn results in diabetes, high blood pressure, coronary artery disease, obstructive sleep apnea, joint pains and infertility. A team of researchers from the Biomedicine Discovery Institute at Monash University in Melbourne, Australia, has recently conducted a study striving to gain a better understanding of the brain mechanisms that contribute to weight gain and loss. They have identified the mechanism through which brain controls the amount of fat that is burned after a meal. They concluded that “Faulty signals” from the brain can promote obesity. Researchers revealed the existence of a "switch" that tells the body what to do with the fat gained after food intake. If the switch is faulty, then the body is likely to store more fat, thus becoming predisposed to obesity. They have found a link between food intake and the process whereby white fat turns into brown fat. In the body, fat is stored in adipocytes or fat cells that make up the adipose tissue. These fat cells can convert from "white" (storing energy) into "brown" (releasing energy). The study found that the brain normally "instructs" the white fat cells to turn into brown fat cells after eating. This happens in response to insulin released from pancreas into the blood in larger quantities as blood sugar levels increase. On the other hand, brown fat cells are turned back into white energy storing fat cells after a period of gap during which no food is consumed. When this mechanism functions normally, it allows the body to stabilize its weight. This mechanism is akin to a switch, "reading" the insulin signals and flipping on and off as appropriate. In the case of people predisposed to excess weight gain, this switch malfunctions, becoming stuck in the "on" position. As a result of this browning is turned off all the time and energy expenditure is decreased all the time, so when you eat, you do not see a increase in energy expenditure - and that promotes weight gain. Bariatric surgery will result in increased levels of GLP 1 and PYY hormones and decreased levels of hormone called ghrelin. This in turn results in stimulation of satiety center in the brain and inhibition of hunger center. Post bariatric surgery, patients feel less hungry and so they eat less. They do not feel tired also. This results in weight loss and resolution of obesity associated comorbid conditions like diabetes, high blood pressure etc.
It's a known fact that water is the elixir of life. Our body consists of 60% water and interestingly our brain is made up of 73% water. Not keeping yourself hydrated affects our brain activity as well. What happens if you don't drink enough water? Well, a lot of things. Muscle cramps, fatigue, extreme thirst, dry mouth, mild constipation, temporary lightheadedness and more. How does hydration help us? It keeps the blood pressure optimised, body temperature correct, joints are lubricated, waste is removed out of the body, good digestion. Exercising and keeping the body fit is important. But do not forget to keep your body hydrated this summer.
Leptin , Obesity & Weight loss Leptin is a hormone secreted by the adipose tissue (fat cells). It controls hunger and feelings of satiety. Leptin acts on the hypothalamus of the brain. The amount of leptin released is directly related to the amount of body fat. In a normal person, the more fat a person has, the more leptin they will have circulating in their blood. This in turn acts on the receptors of the hypothalamus and you know when it’s time to stop eating. It then increases the metabolic rate in order to achieve energy balance. In Obese people, even though there is a lot of leptin hormone in the blood, it fails to act upon the brain. This is called Leptin Resistance. In this state, the brain does not read a signal to stop eating. So it leads to over eating, cravings. The cause of Leptin Resistance is unknown.
Tips to reduce and maintain healthy weight Do not skip meals Eat balanced diet. Include cereals , pulses, green leafy vegetables, other vegetables, moderate vegetable oil(un saturated), fruits, restricted sugar, skimmed milk and its products daily in proper quantities to meet the requirements of carbohydrates, protein, fat, vitamins, minerals and fibre by the body. Calorie reduction is the most important requirement for weight loss. Cut down of 100 calories per day leads to 4.5kg weight reduction per year.The total calories from food should be 25-30% from fat in the form of unsaturated fat, 15% from protein and 50-60% from carbohydrates in the form of complex carbohydrates like wholegrains, vegetables and fruits.Reduction of 500calories from Basal energy expenditure helps to reduce 9 kg weight per year. Go for whole cereals and pulses like wheat, ragi, jowar, millets rather than refined ones like maida and its products like bread, biscuits, refined noodles, pastries etc Don’t be over restrictive like avoiding one or two meals and replacing it with fruits or juices. Regular physical exercise(brisk walking for 45 minutes for 5 to 7 days a week) Physical activity contributes to weight loss, decreases abdominal fat, increases cardio respiratory fitness. Exercises like aerobic exercise, swimming, bicycling, jogging, dancing leads to these benefits. Brisk walking is one of the easiest ways applicable to almost all age groups. Weight lifting can also be helpful to loose weight. You should be more active everyday by doing routine work like climbing up stairs rather than taking elevator or walking somewhere rather than driving , engage yourself in gardening, household work rather than using electronic gadgets and this can help you to burn calories without much difficulty. Watch your food portion size Inclusion of liberal amount of fresh vegetables and fruits reduces hunger pans, maintains your blood sugar and prevent constipation because of its fibre content and it is abundant in phytochemicals , antioxidants which prevent against cancer Try to include fruits with skin because deskinning removes fibre. No fat or low fat dairy and its products can be used. Drink liberal amounts of water frequently like one glass of water once in two hours intervals. Get rid of deep fried items and calorie dense foods. Avoid fatty items like mutton, beef, pork, crab, prawns. Include fish or fish oil , soya and its products weekly twice because of its omega3fatty acid content. Eggwhite can be taken daily. Healios Obesity and Diabetes Center Nutritive sweeteners: White and brown table sugars, molasses, honey, syrups are nutritive sweeteners.In addition sugar alcohols derived from fruits (or) commercially made are also nutritive sweeteners.The most common sugar alcohols include sorbitol, mannitol, xylitol and maltitol.All nutritive Sweeteners provide calories to the body and may affect your blood glucose. Non nutritive sweeteners are the true artificial sweeteners. They do not provide calories and will not influence blood glucose. These include Saccharin, Neotame, Aspartame, Sucralose, Stevia Acesulfame Potassium(Ace-k)
Post Bariatric Surgery TIP 3 Know why protein rich food is important after undergoing a Bariatric Surgery. Body needs protein to build and maintain tissue and muscles. It promotes metabolic activity which in turn burns fat. It is also needed to heal wounds. Eating protein-rich foods first at every meal promotes healing from your surgery and to help you maintain lean muscle as you lose weight. So it is advised to intake protein rich food after Bariatric surgery. Ideally it is best if cooked using low-fat cooking methods. Choose lean protein like skinless chicken. Recommended protein intake is 60-65 gms of protein each day. But sometimes, it is difficult to get that amount through diet only. It can be compensated by protein drinks. But keep in mind, the extent of food your pouch can handle.
Post Bariatric Surgery TIP 6 Include regular Physical Activity as a life style change.
Dancing after Obesity Surgery Most of the people at some point would have thought “Wish I could Dance”. Well, YOU CAN. It would be a double advantage if you are trying to lose weight. Weight loss need not be a boring or a strenuous activity. It can be a thing that you always wanted to try. Put on your dancing shoes, pair up with your spouse or a buddy, and shake it like Elvis. After Bariatric Surgery or Obesity Surgery, when you are most focused on weight loss, make it a fun activity. Enjoy your passion for dancing and in the process, lose some weight.
People who have undergone Bariatric Surgery are not as motivated by food. Does Weightloss surgery / Bariatric surgery disconnect your mind from food? Its probably true. Weight-loss surgery helps to 're-wire' the brain, leaving people less interested in food, a study has found, where MRIs were given to a group of sixteen participants who lost weight via dieting and fifteen who had undergone bariatric surgery. 'They're not as interested in eating, ' said lead author Amanda Bruce, psychologist at the University of Missouri-Kansas City and the University of Kansas School of Medicine.
Exercise / Physical activity on a daily basis increases insulin sensitivity and uptake of insulin by the muscle cell . Thus, it helps diabetics keep their sugars under control.
