Grapefruit May Help Dieters Lose Weight After All
Originally touted to jump start the body's metabolism, the "Grapefruit Diet" is likely the most scrutinized fad diet in history. During the disco era of the 1980s, many weight conscious Americans believed that eating grapefruit multiple times a day was the magic bullet they were seeking. Since those early days of dieting frenzies, researchers have proven the original grapefruit diet to be potentially dangerous due to dramatic restrictions in what else you were allowed to eat. From the food science perspective, this was just the first of many low-calorie menu plans that centered on a magical ingredient.
Nutrition and Medical Research Centre Findings
The Nutrition and Medical Research Centre at Scripps Clinic in San Diego was tasked with providing more in-depth studies to dispel or confirm grapefruits role in weight loss. Research findings quickly identified the popular diet as a myth. There was no evidence to prove that grapefruit could kick start a person's metabolism to better digest and absorb foods. Similar to findings with other fad diets, if you restrict the daily intake of calories, you will lose weight. Once again, the only healthy way to lose weight and keep it off is to eat a balanced diet of wholesome food and stay physically active. Shucks! Not what people wanted to hear.
New Evidence on Grapefruit and Weight Loss
More than three decades later, the dedicated researchers at Scripps Clinic have changed their mind about grapefruit's role on weight loss but not about the dangers of the grapefruit diet. New evidence proved that control groups of non-dieting individuals lost an average of 3.3 to 3.6 pounds in 12 weeks while the non-grapefruit group didn't lose any weight at all. However, the cause and effect was not attributed to metabolism but the fruit's ability to lower blood sugar levels (about 13%), which is similar to the popular diabetes medication Metformin. Improved insulin sensitivity also affected other areas including suppressing appetite and reducing LDL cholesterol levels.
NOTE: Before you add grapefruit to your diet, check with your physician. Unlike most citrus products, grapefruit can interact with medications for treating blood pressure, infections, anti-clotting and more.
