A study published in the Journal of Medicinal Food suggests that both extracts of grapefruit and helichrysum can aid in weight loss.
A lot of research has been done on the potential use of flavonoids for obesity management due to their antioxidant and anti-inflammatory properties. These properties of flavonoids are beneficial to people who are overweight or obese, who typically suffer from inflammation and have a higher likelihood of having insulin resistance.
For the current study, researchers from Spain and Austria looked at the antioxidant and anti-inflammatory effects of grapefruit and helichrysum extracts in overweight insulin-resistant rats. Grapefruit is a tropical citrus fruit rich in nutrients, antioxidants, and fiber, while helichrysum is a flowering plant with many healing properties, including antioxidant properties.
In conducting the study, they first studied two groups of rats: a control group and a high-fat sucrose group. For 22 days, they fed rats in the high-fat sucrose group with water and food as much as they can. After that, they put the rats back to a standard diet and re-assigned them into three groups. One group did not receive any supplements, while the remaining groups received one gram per kilogram body weight (g/kg BW) of grapefruit extract or two g/kg BW of helichrysum extract every day for five weeks.
The results revealed that rats supplemented with grapefruit and helichrysum extracts gained less body weight during the five-week treatment, and displayed lower levels of serum insulin and liver thiobarbituric acid reactive substances (TBARS). Insulin resistance was also improved in both groups. In addition, researchers observed decreases in tumor necrosis factor-alpha gene expression in body fat tissue and intestinal mucosa, and toll-like receptor 2 (TLR2) expression in the intestinal mucosa.
These results suggest that extracts of grapefruit and helichrysum can boost weight loss, lower elevated insulin levels and insulin resistance, and improve inflammation. These extracts can also reduce oxidative stress brought about by the high-fat sucrose diet.
With these findings, the researchers concluded that either extract of grapefruit or helichrysum may be used for losing weight and improving insulin resistance among overweight and obese people. (Related: 3 Natural drinks that can promote weight loss.)
