The latest studies showed that obesity is a worldwide concern.

(Mirror Daily, United States) – According to the date provided by a preliminary study, obesity could be treated with bariatric embolization. The procedure is commonly used in managing stomach bleeds, but it also proved itself useful in controlling the hunger hormone.

Clifford Weiss, the lead author of the study and an associate radiology professor at Baltimore’s John Hopkins University, believes that obesity could be treated with bariatric embolization.

For the moment, the idea is purely theoretical, and the radiologist and his team will begin a much more elaborate study in order to analyze the potential that the procedure could have.

The United States Health National Institutes believe that the method could be accompanied by a series of dangerous health risks. For example, they stated that on a short-term basis the bariatric embolization could cause infections and bleeding. Furthermore, on the long term, the procedure could trigger dangerous hernias.

Bariatric embolization is a medical procedure used by surgeons when patients are at risk of bleeding into their stomach. In order to prevent that from happening, they inject microscopic beads into the artery that is supplying the stomach.

Upon analyzing a sample of 32 patients that had the procedure, Weiss and his team discovered that there is a connection between the blocked artery and weight loss.

Upon further investigation, he found that patients who had the beads injected into their left gastric artery lost approximately eight percent out of their total body weight in three months.

By contrast, people that had the beads injected into a different artery only lost one percent out of their total body mass.

The explanation for this occurrence is simple. The left gastric artery is responsible for supplying the fundus, which is a part of the stomach which produces the ghrelin hormone or the hunger hormone.

Due to the fact that the microscopic beads slow the blood flow from the artery to the fundus, the ghrelin hormone is produced in smaller quantities, thus making the patient crave less food.

Weiss presented his preliminary conclusions during the annual meeting of the International Radiology Society that took place in Vancouver, Canada.

Some of his colleagues were skeptical about his research, stating that the procedure could prove to cause much more complications than relevant weight loss progress.

Others were pleased with his presentation saying that the John Hopkins professor is on his way to revolutionizing the treatment of obesity.

Obesity could be treated with bariatric embolization, but only if the broader study concludes that the procedure is safe for the patients.

(Mirror Daily, United States) – It may not be news for some, but you won’t lose weight just by exercising, an observation underlined by a new study who focused on energy expenditure. It’s important to maintain balance, and focus on both regular workout sessions and a healthy diet. Just one of them separated won’t be of much help.

Lead author of the study, Herman Pontzer from the City University of New York made the observation when he was working among the Hazda. They are a population of hunter-gatherers in northern Tanzania that are incredibly active. Each day, they walk long distances and do a lot of physically demanding work. However, he found that their daily expenditure of energy were not dissimilar to those with more sedentary lives in modern United States.

The researcher then conducted a study on 300 men and women, studying the amount of daily exercise along with the amount of burnt calories. They observed that more exercise does indeed burn more calories per day, but that’s only until a certain point. There’s a moment when the body hits its limit, and no matter the extra work, it won’t be spending the extra energy.

That means that the energy expenditure of people with moderate regular workouts was not that much different than those with excessive exercise. All the extra time spent exercising did not result in them actually burning off more calories. That is because their body then adapted to the activity and stopped spending as much energy as it did before for a workout session. So, in essence, moderation is still key.

According to Pontzer, his study doesn’t aim to change the notion that exercise is healthy for our body and minds. In fact, it strengthens it, but at the same time, it underlines the fact that there should also be a focus on diet. By simply exercising more and more each week, people won’t achieve their desired results. There are more factors that come into play.

People who start exercising and losing weight will notice after a few months that the rhythm of their weight loss has slowed. Their bodies have adapted to the new routine and were burning much fewer calories than they did before. After a certain point, the extra work is not worth it in terms of weight loss. However, accompanying that with a healthy diet will do the trick. So, if you think that having a pizza because you’re doing two extra laps around the park will balance itself out, it won’t.

There might be a so called “sweet spot” for physical activity to achieve the desired results. Too little and we’re unhealthy, but too much and our bodies adapt so it won’t result in continued weight loss. The trick is moderate exercise and a healthy food pallet to shed those extra pounds.
