Background

  • There are many versions of the grapefruit diet, which was developed in the 1970s. However, they all require the intake of one half of a grapefruit before every meal. Some versions require that dieters eat until they are full, but most diet plans limit daily caloric intake to less than 800 calories. The average dieter generally participates for one to three weeks.
  • The diet is based on the idea that grapefruits contain an enzyme that helps the body use fat for energy. Proponents of the diet claim that eating grapefruit before a meal will give the consumer the benefit of fat-burning enzymes.
  • The grapefruit diet breakfast typically consists of 1/2 of a grapefruit, two eggs prepared any way and two slices of bacon. Lunch generally consists of 1/2 of a grapefruit, a salad with any type of dressing and as much meat as desired. The typical dinner consists of 1/2 a grapefruit, a salad with any type of dressing or red or green vegetables prepared with butter and/or spices, meat or fish, and 1 cup of coffee or tea. Snacking in between meals is not permitted. However, one cup of skim milk can be consumed as a bedtime snack.
  • Grapefruit is low in calories, contains no fat and has minimal sodium. Grapefruit also contains an abundance of vitamin C and pink grapefruit contains beta-carotene. Anecdotal evidence suggests that the diet causes rapid weight loss.
