Bitter Orange : Amazing Weight Loss Benefits and How Can You Add it to Your Diet
Bitter orange is a fruit that may not have gained popularity due to its resisting taste. But it has certainly gained the attention of scientists worldwide. It is increasingly being used for making extract for weight loss. It has gained global attention, especially after a study showing its effectiveness as a weight loss supplement closer to that of a popular prescription drug.
The Department of Physiology, Medicine and Pathology, Georgetown University Medical Center, Washington conducted a study and found Citrus aurantium (bitter orange) to be an effective weight-loss replacement for the drug ephedra.
So how does bitter orange help you with losing weight?
The Presence of Alkaloids
Bitter orange is rich in different alkaloids. These include:
Some of these alkaloids target beta-3 adrenergic receptors, thus promoting fat breakdown.
There are many animal based, in-vitro, and even human studies that show that bitter orange is beneficial in weight loss.
In one such study, bitter orange, St. John’s Wort and caffeine were given against a placebo to overweight adults after a weight loss program that involved exercise and low-calorie, low-fat diet.
The researchers found that the bitter orange group lost much more weight and fat. Their metabolic rate also increased after 6 weeks.
The study also found absence of any side effects in the markers of liver, renal and cardiovascular functions.
There are many more similar studies that give you good reasons for adding bitter orange into your diet if you want to lose weight.
There is another study conducted at the Creighton University Health Sciences Center, Omaha, it was found that the Synephrine in the fruit helped in increasing basal metabolic rate, helping in weight loss.
Researchers have also come to the conclusion that unlike ephedra, synephrine cannot be converted to its phenolic group. So the medical field doesn’t have to worry about conversion of the alkaloid into unwanted amphetamines, which has been the case with ephedra.
Ephedra has been banned by the FDA due to its impact on blood pressure levels. Preliminary studies have indicated that synephrine (from bitter fruit) is safe, but more studies are underway.
