Researchers there found that the simple act of adding grapefruit and grapefruit juice to one's diet can result in weight loss.
The
basic idea behind this diet is to eat grapefruit whenever you can,
drink a glass of unsweetened grapefruit juice with every meal, add
grapefruit to cocktails and also to salads. Grapefruit is supposed to go
well with the lean meat from crab and chicken and with vegetables, such
as red onions, spinach and celery. The biggest advantage is, of course,
the fact that grapefruit is virtually fat-free and has few calories. An
entire grapefruit has about 70 calories, which means that you can eat
about as much as you can stomach and still lose weight.
The best thing about the Grapefruit Diet is a recent study carried out by a team of scientists led by Doctor Ken Fujioka, from the Nutrition and Metabolic Research Center of the Scripps Clinic in San Diego. The study has found that, contrary to the opinions voiced by experts in the 1980s, adding grapefruit and grapefruit juice to your diet can actually help you lose weight. And what's really great about it: you don't have to change your eating habits at all. Naturally, eating less fat and sweets and doing some exercises is a very good way of speeding up the weight loss process, but you don't have to go out of your way with this diet.
The study included 100 obese people who were divided into three groups. The first group ate half a grapefruit before each meal three times a day. The second group drank grapefruit juice before each meal. The third group received no grapefruit. No other changes were made to their diets.
After 12 weeks, those participants who ate grapefruit with each meal lost, on average 3.6lb. Only a third of a pound a week, but pretty good considering they didn't make any other changes to their diet. Meanwhile, those who drank grapefruit juice three times a day lost 3.3lb in the 12 weeks. By comparison, the grapefruit-free participants lost, on average, only 0.5lb.
But weight loss wasn't the only health benefit seen when grapefruit or the juice was consumed. The research also found the grapefruit-consuming participants had lower levels of insulin, a hormone that regulates blood sugar levels and fat metabolism, which in turn might help to reduce the risk of diabetes or stroke.
The researchers believe grapefruit contains unique plant compounds that reduce insulin levels, which in turn promotes weight loss.
The link between raised insulin levels and excess weight is complicated and multifaceted. To start with, high levels of insulin may indicate that sugar isn't efficiently utilised for energy with the result that it's more likely to be stored as fat. Secondly, high levels of insulin can make people feel hungry so that they eat more. And finally, high levels of insulin prevent the body from breaking down fat. Add these together, and it's easy to see why lower levels of insulin may promote weight loss. What exactly it is in grapefruit that has this insulin-lowering effect remains unclear.
According to the study, eating half a grapefruit before each meal and exercising a bit every day helped a group of obese people drop an average 3.6 pounds in 12 weeks without any change in their eating habits whatsoever. A second group had to drink a glass of grapefruit juice before every meal and lost 3.3 pounds in the same 12 weeks. While it's true that losing 1 pound per month gives a whole new meaning to the phrase "slow diet", you have to appreciate a diet that lets you eat whatever you like and still shed a pound per month. If weight loss is not a stringent affair, then you can stick to this diet for a long time and reap the benefits.
