Ronald Evans, director of the Gene Expression Laboratory at Salk, says the added diet pill - called fexaramine - acts considering an "imaginary meal."
"It sends out the related signals that normally happen to come you eat a lot of food, consequently the body starts clearing out heavens to accrual it. But there are no calories and no fiddle when in appetite," he explains.
When tested in obese mice, fexaramine was found to initiation fat loss, prevent weight profit, run blood sugar and condense cholesterol and inflammation.
Evans and colleagues recently published their findings in the journal Nature Medicine.
Fexaramine targets the body's farensoid X receptor (FXR) - a protein that is operating in food digestion, fat and sugar storage and the general pardon of bile acids from the liver.
The researchers counsel by that following we activate eating a meal, FXR is activated in preparation for food intake. Past studies from Evans and team have indicated that as accurately as triggering the freedom of bile acids to aid digestion, FXR alters blood sugar levels and switches in parable to a fat-flaming process.
Some existing diet pills set in motion an array of pathways controlled by FXR - including the intestines, liver, kidneys and adrenal glands.
Fexaramine, however, by yourself activates the FXR alleyway united to the intestines. When taken orally, the diet pill is single-handedly absorbed in the gut and does not enter the bloodstream, meaning it is unlikely to cause the side effects typically allied subsequently existing diet pills - such as high blood pressure, dizziness, insomnia and even heart lawlessness.
What is more, the fact that fexaramine unaided acts in the intestines means it is a more on the go weight loss aid, according to the researchers, as the drug is not transported throughout every one of body.
'Body's adaptableness to a meal is as well as a relay race; we've college how to trigger the first runner'
To test the effectiveness of fexaramine, Evans and colleagues gave obese mice a daily dose of the drug for 5 weeks and compared the outcomes following mice that remained untreated.
The mice massive fexaramine stopped gaining weight and maxim a reduction in body fat, blood sugar and cholesterol. What is more, the body temperature of the treated mice increased, indicating a heightened metabolism, and some of the rodent's white fat deposits were converted into healthier, simulation-shining fats.
The team says they moreover saying a regulate in the assortment of bacteria in the gut, but they note that they are formless re what this indicates at completion.
Evans says fexaramine is more functional than diet pills that put into charity numerous FXR pathways because it activates the mechanisms by which the body naturally responds to a meal. He explains:
"When you eat, you have to speedily trigger a series of responses every one share of throughout the body. And the realism is that the totally first responder for every this is the intestine.
The body's recognition to a meal is behind a relay race, and if you declare every the runners to go at the same epoch, you'll never additive the baton. We've literary how to set in motion the first runner consequently that the on fire of the deeds happen in a natural order."
Obesity is a major hardship in the US, affecting on summit of a third of adults. Evans and colleagues take on fexaramine is a promising candidate to reduce obesity and the risk of its linked diseases - such as type 2 diabetes - in humans.
They aim the drug would be used the length of diet and lifestyle changes asleep the auspices of health care professionals.
The team is now in the process of setting happening clinical trials to assess the effectiveness of fexaramine in humans.
