Melatonin is a natural hormone segregated by the body and melatonin levels generally increase in the dark at night. It is also found in fruit and vegetables like mustard, Goji berries, almonds, sunflower seeds, cardamom, fennel, coriander and cherries.
Spanish scientists have discovered that melatonin consumption helps control weight gain because it stimulates the appearance of 'beige fat', a type of fat cell that burns calories in vivo instead of storing them. White adipose tissue stores calories leading to weight gain whereas 'beige fat' (also known as 'good or thinning fat') helps regulate body weight control, hence its metabolic benefits.
In the Journal of Pineal Research, scientists from the University of Granada Institute for Neuroscience, the Hospital Carlos III, Madrid, and the University of Texas Health Science Center in San Antonio (USA) have revealed, for the first time, the previously unknown enigma of why melatonin has metabolic benefits in treating diabetes and hyperlipidemia.
In earlier publications, the researchers analysed the effects of melatonin on obesity, dyslipidemia, high blood pressure and type 2 diabetes mellitus associated with obesity in young obese diabetic Zucker ratsan experimental model of metabolic syndrome.
In view of their most recent results, it seems the key lies in the fact that chronic melatonin consumption not only induces the appearance of 'beige fat' in obese diabetic rats, but also increases its presence in thin animals used as a control group. 'Beige fat' cells are found in scattered lentil-sized deposits beneath the inguinal skin in obese diabetic Zucker rats.
Melatonin is a natural hormone segregated by the human body itself and melatonin levels generally increase in the dark at night. It is also found in small quantities in fruit and vegetables like mustard, Goji berries, almonds, sunflower seeds, cardamom, fennel, coriander and cherries. These findings, together with t
