WHAT’S INVOLVED: The basic principle behind the Grapefruit Diet is to have half a piece of the fruit before every meal. You should follow the diet for 12 days followed by two days off. The recommended daily food intake is as follows:

Breakfast: Start with half a grapefruit followed by two eggs and two slices of bacon.

Lunch: Have half a grapefruit followed by a serving of any meat with salad.

Dinner: For your final meal of the day have half a grapefruit followed by a meal of meat or fish and vegetables. The best vegetables to have are red onions, green onions, bell peppers, cucumber, broccoli, spinach, lettuce, cabbage, carrots or peas. While following the diet you should avoid white onions, potatoes and celery.

VERDICT: Dr John Briffa is quoted in The Guardian as saying that the most positive outcome of including grapefruit in your diet is that it’s rich in naringenin, which helps protect against certain cancers, including those of the breast, lung and pancreas. The Wellness Brothers Clinical Nutritionist and Conditioning Coach, Ryan Penny offers this advice: “Most people have heard of the grapefruit diet. It has been around since the 1930s and falls into the category of ‘Low-Carb-Moderate-Protein-Low-Calorie diet.’ That description is probably more of a mouthful than any part of the diet will be.  The diet claims to be a magic fat-burning one, which has not really ever been proven. It certainly does lead to weight-loss, but then so will any low-calorie diet lasting 12 days. What is lost, however, is not just fat, but rather a combination of water, glycogen, muscle and fat. Not ideal.  In truth the diet would probably be as effective without the grapefruit. Apart from grapefruit being a really good food, it does contain naringenin which can block the action of important liver enzymes. This is especially problematic for people taking certain medication. As a rule, if you are planning to try out this diet and are taking any medication, be sure to check the package insert of the drug to see if grapefruit or its juice is to be avoided. Rapid weight loss, yes. Rapid weight regain after the 12 days. Also yes. You can definitely do better!”
