Eat with ease for weight loss
In a study published in Cell Metabolism, Srinivasan was able to determine that while serotonin does help trigger fat loss, it works better when combined with adrenaline. What we found is you can activate fat loss by just giving serotonin but in order to do that you need some amount of adrenaline to be present. If you take away the adrenaline-like component of the signaling, the serotonin still works but the efficacy is greatly reduced, Srinivasan told FoxNews.com. The same is true for the adrenalin-like signalingEach part of the circuit, or each neurotransmitter, requires the other. Furthermore, Srinivasan was able to confirm that altering serotonin and adrenaline facilitated weight loss in worms regardless of how much food they were consuming. We found that the receptors that control feeding behavior are distinct and separate from the ones that control fat loss, Srinivasan said. The reason you see fat loss in serotonin-treated animals is because they are burning more fat and expending more energy. Though human applications for these findings are still speculative, Srinivasan notes that the study might help pave the way for better weight loss drugs in the future. In fact, the now-banned weight loss drug Fen-Phen was a serotonin-plus-adrenaline-boosting therapy, according to Srinivasan.

In weight-loss surgery, skill matters. A lot.
Common behavioral strategies included setting weight loss goals, dietary goal-setting and balancing calories. However, seven evidence-based behavioral strategies for weight loss were completely missing, such as stress reduction, relapse prevention, social cues, negative thinking, developing regular patterns of eating, time management, and instructions on reading nutrition labels. We think apps can grow into more sophisticated and impactful tools if they include strategies to help with diet motivation and adherence, which are super important for weight loss, Pagoto noted. The ability for real-time information, monitoring and support may help individuals change their diets and exercise in ways that have previously required time-intensive and/or face-to-face intervention, said Wendy Nilsen, Ph.D., a health scientist administrator at the NIH Office of Behavioral and Social Sciences Research (OBSSR). The authors findings, similar to work in smoking cessation, highlight the lack of integrated behavioral science in app development. Theres more to do, Nilsen added. For apps to be able to effect maximal behavior change, developers are missing important opportunities to improve their applications by overlooking a well established literature in the behavioral sciences and to incorporate existing knowledge into new technologies. Further, this work can help determine when a well-designed app alone is most likely to help someone to reach their health goals and when more intensive intervention, such as the use of a coach, is needed.

A lot. A study published this week in the New England Journal of Medicine found that when it comes to performing laparoscopic gastric bypass surgery, the difference between having the most highly skilled surgeon and having one whose skill level lies in the bottom quarter of the pack is huge. Patients operated on by bariatric surgeons whose surgical skills fell in the bottom 25% had more than four times the number of surgical site complications as patients whose surgeons ranked in the top 25% (4.6% vs. 1.04%). They had more than four times the pulmonary complications, such as blood clots that traveled to the lungs (3.91% vs. .71%).

When we eat slowly, we feel satisfied and tend to eat less because our senses are more alert n send the signals to the brain saying the stomach is full. For the record a normal human needs only a fistful of food for one meal, that’s the size of our stomach. In this way we can end a meal when we’re actually satisfied instead of stuffed. Scientists have said that the very sight or smell of food sets about the brain activity that delivers the signal that we have eaten enough. It takes about twenty minutes into the meal, for this whole process to be completed and for our brain to get the signals from the digestive system that we are ‘full’. Therefore when we eat fast or in a hurry we tend to stuff ourselves more than required. By the time our brain sends its signals we would have already finished eating way more than what we should have in the same time span.
