Current Research On Weight Loss


The battle on weight loss is ongoing.  New research continues to try to help more people lose weight, as the current rates of obesity and being overweight in America continue to rise. There are products on the market that are proving to be beneficial to those who are having problems losing weight. Current medical research also continues to study how food choices and dietary habits impact weight. Much is being learned about the way the body processes nutrients at the cellular level.


Xerisan™ is a new type of diet pill that is specifically designed for those who are extremely obese.1  It comes with a new ingredient, known as Phaseolus Vulgaris, which works on a digestive enzyme in a way that influences body composition in a positive manner.  Research is studying the combination of Xerisan with a variety of other ingredients, including Calcium Pyruvate and Synephrine, to help suppress appetite and stimulate the fat metabolism without creating negative cardiovascular side effects that are commonly reported when using other weight loss medications. Some small studies have shown modest weight loss over placebo, but other studies have found no improvement in weight loss over placebo. More research is needed at this time.

As with any weight loss medication, only using it in combination with an adjustment with one’s eating habits will provide the beneficial effects that one is expecting from such a weight loss medication.

Eating a Smaller Lunch Could Be Key to Losing Weight

A Cornell University study has taken a new approach to dietary research. Researchers studied the role of meal size in weight gain. The study reports that eating a smaller lunch may be the key to losing weight without skipping lunch or drinking a weight-loss shake.2

Participants in this study who consumed portion-controlled meals at lunchtime did not try to make up for those lost calories by consuming more calories later in the day.  This indicates to researchers that the body fails to detect a small reduction in energy intake; hence the body didn’t trigger a need to replace the reduced calories later in the day.

The 17 participants in this study ate whatever they chose from a buffet for 7 days.  During the next 14 days, half of the group chose their lunches from one of six portion-controlled items, while being able to consume as much as they wanted during their other meals and snacks.  During the next 14 days, the other half of the group did the same procedure.

The end result was that while eating the portion-controlled lunches, each member of the study ate 250 fewer calories each day, losing an average of 1.1 pounds.

Researchers concluded that a person who did this could lose at least 25 pounds per year.  This was also a simple, inexpensive way for a person to consume fewer calories and it shows that it can be relatively easy for anyone to reduce their calorie intake, regardless of income.

Aerobic Exercise May Be Better Than Resistance Training In Removing Stubborn Belly Fat

A study conducted by Duke University Medical Center concluded that aerobic exercise may be better at eliminating belly fat than resistance training.3

Aerobic exercise is any exercise that raises the heart rate and causes the heart and lungs to work harder to gain more oxygen that the body needs during strenuous physical activity.  Activities can include cycling, jogging, rowing, running, and swimming.  Resistance training is any exercise that uses the force of a muscle against some type of resistance in order to build up the size and strength of that muscle.  Activities can include chin-ups, moving or holding in position elastic or hydraulic devices, push-ups, and weight training.

The study showed that aerobic exercise burns 67% more calories than resistance training.  In addition, aerobic exercise greatly burned belly fat, while resistance training had virtually no impact on belly fat.  Adding resistance training to aerobic exercise did not improve the results of removing belly fat as compared to just doing aerobic exercise alone.

While the study involved “rigorous and substantial” training, the authors of the study believe that people can achieve similar results by doing aerobic exercise at a more moderate level, just that it will take longer to see the same results.

Increasing Free Radicals Could Be The Key To Controlling Appetite

In a recent study of brain circuits that control the feelings of hunger and satisfaction, the Yale School of Medicine discovered that molecular mechanisms that control free radicals may be the key to the increased appetite in obese people.4

By increasing the amount of free radical levels in the hypothalamus (portion of the brain that contains small nuclei that control a variety of functions, including thirst, hunger, sleep, fatigue, body temperature, and daily rhythms), there is the activation of melanocortin neurons that promote the feeling of satisfaction.  This, in turn, can turn off the increased appetite in obese people.

One caveat to this potential method is that free radicals are thought to also accelerate the aging process.  If cells are exposed to these free radicals, they can receive damage and age more rapidly than they should.

This is why a cellular mechanism will activate upon overeating.  The mechanism is designed to stop these free radicals from forming so that they do not damage the body’s cells.  However, the drawback to this mechanism when it comes to weight loss is that the ability to feel satisfied after eating is delayed, causing that person to eat more, which can lead to additional weight gain.

The authors of this study have theorized that this inverse relationship between the feeling of fullness and the damage to cells from free radicals may partly explain, at least, why most therapeutic strategies to dealing with obesity conjure up severe side effects.  Further research is needed to determine whether there is a way to utilize the free radicals to promote fullness in obese people without causing critical damage and premature aging to their bodies’ cells.

Research Into New Weight Loss Medications and Treatments Continues

Weight loss research continues, as the obesity epidemic spreads across the United States and throughout the world.  The numbers continue to indicate that more and more people will become obese in the coming years.  Diet and exercise continue to be the tried and true methods for losing weight and maintaining an ideal weight, but it is hoped that current and future research will lead to new medications and treatments that will help those who are obese and who have not lost weight even with dietary and exercise changes to finally be able to lose that excess weight and live healthier lives.
