This fruit increased fat loss after 12 weeksI'm back with another quick tip today that can help to enhance your fat loss efforts...
I recently came across this study published in 2006 in the Journal of Medicinal Food, titled "The effects of grapefruit on weight and insulin resistance"... the study measured results after 12 weeks of 91 obese patients broken down into a placebo group, a group that received a half of a fresh grapefruit before each meal (3x a day), a group that received an 8 oz glass of grapefruit juice before each meal, and a group that received a grapefruit capsule before each meal.
The results were interesting...
It turned out that grapefruit before a meal DID in fact increase fat loss, with the fresh grapefruit group losing the most weight, although even the grapefruit juice group and the grapefruit capsule group lost more than the placebo group.
The study concluded, "There was also a significant reduction in 2-hour post-glucose insulin level in the grapefruit group compared with placebo. Half of a fresh grapefruit eaten before meals was associated with significant weight loss. Insulin resistance was improved with fresh grapefruit."
It's interesting to note that the fresh grapefruit improved insulin sensitivity, thereby helping to control insulin and blood sugar levels, despite the carbohydrates contained in the grapefruit. This is similar to the results I showed you in this interesting article where pre-meal lemon juice was also shown to control the blood sugar response from a meal...yet another example of a citrus fruit improving insulin sensitivity.
I would also venture a guess that this result might also be seen in fresh squeezed lime juice, but I have not seen any studies on this as of yet.
