Researchers became interested in raspberry ketones because of the molecular structure.
They noticed that it looked very similar to two other molecules, capsaicin (found in chili pepper) and synephrine (a stimulant).
Several studies have shown that these two molecules can boost metabolism, so it was speculated that raspberry ketones could have the same effect.
When researchers took isolated fat cells from rats and made them grow in a test tube, adding raspberry ketones to the mix had two effects:
- It increased lipolysis (breakdown of fat), primarily by making the cells more sensitive to the effects of the fat burning hormone norepinephrine.
- It made the fat cells release more of the hormone adiponectin.
Adiponectin is a hormone that is released by fat cells and is believed to play a role in regulating metabolism and blood sugar levels.
Thin people have much higher levels of adiponectin than people who are overweight and the levels of the hormone increase when people lose weight.
Studies have shown that people with low adiponectin levels are at a higher risk of obesity, type 2 diabetes, fatty liver and even heart disease.
Therefore, it stands to reason that raising adiponectin levels with natural means could help people lose weight and lower the risk of many diseases.
Raspberry ketones have a similar molecular structure as two known fat burning compounds.
They can make isolated fat cells break down fat and release a hormone called adiponectin.
CLINICAL STUDIES HAVE PROVEN THAT IT WORKS
Raspberry ketone supplements have shown promise in studies on mice and rats.
In one of the studies, a bunch of mice were fed an unhealthy, fattening diet. Some of the mice got raspberry ketones… others did not.
This is what happened:
As you can see, the mice in the raspberry ketone group weighed 50 grams at the end of the study. The mice that didn’t get raspberry ketones weighed 55 grams (a 10% difference).
Another study was conducted in 40 rats, also fed a fattening diet. In this study, the rats given raspberry ketones had increased adiponectin levels and were protected against fatty liver.
The tests were successful in showing weight loss had been achieved purely from adding Raspberry Ketones as a supplement to the diet of the test subjects
