Exercise Modifies the Brain to Help Weight Loss, Finds New Study

Afp-Relaxnews / November 25, 2011

(Relaxnews) – A study examining the neuro-relationship between exercise and diet has found that in addition to fostering healthy eating habits, exercise also increases people’s sensitivity to signs of fullness and satiety and helps overcome food temptations. According to a Harvard study published for the Spanish Foundation for Science and Technology when exercise is added to a weight-loss diet, treatment of obesity is more successful than adjusting diet alone, said researcher Miguel Alonso Alonso.

Adding exercise to the program also helped weight loss subjects adhere to the diet for the long haul.

The study, based on data from epidemiological studies and announced November 23, found that one of the key factors in successful weight loss is a cognitive function known as inhibitory control, the ability to resist a strong inclination or temptation — like overeating — and do what is most appropriate or needed.

According to Alonso, living in an obesogenic environment — an environment that promotes weight gain — presents a constant barrage of stresses on these neuro-cognitive resources, leading to impaired judgement and facilitating impulses to overeat, he said. Exercise, however, helps improve the brain’s executive functions and overcome these strains, he said.

Past studies have also shown that exercise — in the form of table tennis — helped children with developmental coordination disorder to improve their inhibitory control. Meanwhile, according to fitness experts polled by WebMD.com, the most effective exercises for losing weight include walking, interval training, squats, lunges, push-ups, ab crunches and the bent-over row — exercises that either target multiple muscle groups, are suitable for different fitness levels or help burn calories more effectively.

Sept.29.11-10 Minutes of Exercise

10 Minutes of Exercise a Day May Keep the Doctor Away

The above headline is from a June 2, 2010 article in the publication, Medill Reports Chicago, from the Medill School Northwestern University. This article, and several others on the same subject, were based upon a study published in the May 2010 journal “Science Translational Medicine”.

The results of the study basically show that even just 10 minutes of brisk exercise per day trigger metabolic changes that can last up to an hour and can have a positive effect on your health. The study also shows that those who are already fit get more benefit from their exercise than from those who are just starting out.

Dr. Robert Gerszten of Massachusetts General Hospital, and one of the authors of the study showed that metabolic changes began in people after only 10 minutes on the treadmill, and were still measurable 60 minutes after people cooled down.

In this study 70 healthy people were put on a treadmill. The researchers found that more than 20 metabolites changed during exercise and caused naturally produced compounds involved in burning calories and fat as well as improving blood-sugar control.

Dr. Gregory Lewis, a cardiologist at Massachusetts General Hospital and lead author of the study spoke about how profound this study’s findings were by saying, “Its basically like the ultimate intervention. Our large-scale objective is to try and unlock some of the mystery behind why exercise has such beneficial effects.” He added, “What other medicine can you think of that would be associated with living longer, better brain function, better cardiovascular function, better blood vessel function, less depression?”

Dr. Charles Burant, professor of internal medicine at the University of Michigan Medical School, who was not involved in the research responded to the study by saying, “We know that exercise is good for you; the question is why it is good for you, and this paper is a start of understanding this a little bit more.

Dr. Gerszten summed up the benefits of having this new type of information by saying, “The studies to date are really what we like to think of [as] the first comprehensive chemical snapshot of exercise. We have a chemical snapshot of what the fit person looks like. Now we have to see if making someone’s metabolism look like that snapshot, whether or not that’s going to improve their performance.”
