Grapefruit for Weight Loss Study 1
A 12 week study revealed that obese people that consumed half a fresh grapefruit before a meal for 12 weeks showed significantly greater weight loss as well as improvements in insulin resistance linked to metabolic syndrome. Even though the process of this weight loss is not known it appears reasonable to add grapefruit to a weight loss diet.
Grapefruit for Weight Loss Study 2
In a 4 – 12 week study 2 groups of 10 overweight people got either 1.4 grams a day of a citrus dry extract of red orange, orange and grapefruit or a placebo. In the citrus extract group body fat was significantly reduced with a difference of 5.53 percent and 15.6 percent after 4 and 12 weeks, respectively, whilst body weight was significantly reduced with a difference of 2.2 kg and 5.2 kg after 4 and 12 weeks, respectively. The outcomes revealed that the citrus extract effectively breaks stored fat and could help to prevent obesity by bringing down BMI.
