According to Pubmed, lotus leaves are a traditional ingredient in East Asian medicine used to support digestion, reduce fat and diuretic. Polyphenols, flavonoids and alkaloids in lotus leaves can affect lipid metabolism and glucose - two important factors in weight control.
At the same time, lotus leaves are also researched to help stabilize plasma glucose after eating, which is very useful in weight control because large blood sugar fluctuations can stimulate appetite and fat storage.
Oxygenated stress and chronic inflammation are identified as factors contributing to insulin resistance and visceral fat accumulation.
Polyphenols in lotus leaves have been shown to have antioxidant activity, helping to reduce inflammatory index and improve insulin sensitivity in many experimental studies. This can indirectly support weight control through improved metabolism.
A recent clinical study review showed that people who used standardized lotus leaf extract in doses for 8-12 weeks had a moderate weight loss and significantly reduced waist circumference compared to the placebo group, along with a slight improvement in blood lipid and glucose levels.
Although more large-scale and long-term research is needed, current evidence encourages the use of lotus leaves as a natural support in a sustainable weight loss strategy.
Although lotus leaves are considered natural and safe in many cases, not everyone is suitable:
People who are taking medication for chronic diseases: Lotus leaves have the activity of reducing fat absorption and affecting blood sugar; this may interact with antidiabetics or lipid-lowering drugs.
Medication users need to consult a doctor before use.
Pregnant and breastfeeding women: There is still a lack of sufficient evidence of the safety of lotus leaf extract during pregnancy, so pregnant or breastfeeding women should avoid using high doses or only use them after medical advice.
People with severe digestive disorders: Lotus leaves can cause mild digestive disorders (stomach bloating, diarrhea) in some people when used at high doses.
People with irritable bowel syndrome or chronic enteropathy should be cautious...
