Most common causes of obesity are associated with
* An increased intake of energy-dense foods that are high in saturated and trans fat, processed foods and red meat.
* An increase in physical inactivity.
That leads to the accumulation of visceral fat in the body.
Visceral fat in obesity is associated with 90% of patients with ischemic heart disease. In obese, the accumulation of visceral fat is predominant in the intra-abdominal cavity.
Visceral fat is a layer of fat that surrounds the organs. Overexpression of visceral fat has been found to promote insulin resistance, diabetes, heart disease, and inflammation.
However, in non-obese subjects, visceral fat accumulation is correlated with glucose intolerance, hyperlipidemia, and hypertension.
Obesity rates have increased for all age groups in the US over the last several decades, coincidently with the periods that promoted the Western diet.
The WHO in the explanation of the causes of obesity wrote, "Changes in dietary and physical activity patterns are often the result of environmental and societal changes associated with the development and lack of supportive policies in sectors such as health, agriculture, transport, urban planning, environment, food processing, distribution, marketing, and education".
Certain medical conditions such as hypothyroidism, polycystic ovary syndrome, Cushing's syndrome,..., genetic preposition, and use of certain medications that can cause weight gain or water retention, such as corticosteroids, antidepressants, or some seizure medications, also increases the risk of overweight and obesity.
On finding a natural ingredient for the prevention of overweight, scientists examined the root of Angelica sinensis (RAS) supplementation effects on FTO gene expression and methylation status in body weight on an animal model,
Angelica or Dang Gui is a herb of Genus Angelica from the family Apiaceae, indigenous to China.
The herb has been used as a Queen herb in traditional Chinese medicine antispasmodic and vasodilatory agent, and to balance the hormones in women for a normal menstrual cycle and menstruation and strengthen the heart, spleen, kidneys, and liver for both men and women, etc. In other words, it is used to treat gynecological ailments, fatigue, mild anemia, and high blood pressure. It has analgesic, anti-inflammatory, etc.
According to tested analysis, of high-fat-diet (HFD) induced obese female mouse that were divided into groups according to RAS dosage in the diet as follows: normal diet, HFD diet (HC), HFD with low-dosage RAS (DL), HFD with medium-dosage RAS (DM), and HFD with high-dosage RAS (DH). After RAS supplementation for 4 weeks,
* Bodyweight suppression and FTO expression associated with reduced weight in DH mice were significantly higher compared to HC mice and no significant change in FTO expression was detected between DM and DL mice or in their offspring.
* Furthermore, CpG island (the regions with a high frequency of CpG sites) in the FTO promoter was hypermethylated up to 95.44% in the HC group, 91.67% in the DH group, and 90.00% in the normal diet group.
* Most importantly, the adipocyte expression in the DH group were smaller than those in the HC group.
These results strongly suggested that RAS may have a potential role in the inhibition of obesity.
Based on the results, researchers suggest, "RAS could ameliorate obesity-induced by HFD and that the molecular mechanism might be associated with the expression of the FTO gene".
Taken altogether, Dandelion may be considered a remedy for the treatment of obesity, pending to the confirmation of the larger sample size and multicenter human study.
