It is called the Grapefruit Diet because you must have half a grapefruit with every meal. It works for that special event or garment you just have to squeeze into but don’t expect the results to be permanent.
There are different versions of this diet which became popular in the 1930s but basically the rules are 800 – 1000 calories per day spread over 4 meals – breakfast, lunch, dinner and an evening snack with no sugar, sweet fruits and vegetables, grains or cereals.
The vitamin C in grapefruit aids the body’s ability to burn fat as a source of energy. It affects the process of fat oxidation during exercise as well as rest. One study showed that people who consume adequate quantities of vitamin C oxidize 30% more fat while doing normal exercises than individuals with an inadequate quantity of Vitamin C consumption. Daily requirement is about 90 milligrams.
Vitamin C, a water soluble vitamin is lost when exposed to heat, light and air. It is probable that people who have a diet high in processed food are at moderate risk of deficiency.
You can increase your vitamin C by having fresh fruit (e.g. lemon, lime, orange, grapefruit, guava, kiwi, papaya, strawberries, pineapple), dark green leafy vegetables, broccoli, brussel sprouts, cauliflower, capsicum/bell peppers, chili and herbs such as parsley and thyme.
