The citrus diet is based on an increased intake of citrus fruits (lemon, orange, mandarin and grapefruit).

Citrus fruit is known for its high content of vitamin C as well as B vitamins, magnesium, phosphorus, copper and calcium. This fruit does not have a lot of calories so 1 cup (245 grams) of lemon juice contains only 50 calories.

It also contains other substances, such as:

  • Phenolic acids
  • Flavonoids
  • Citrus acid
  • Alkaloids
  • Essential oils

All these ingredients exert different beneficial effects on health, such as:

  • Neuroprotective effects
  • Cardiovascular protective effects
  • Anti-inflammatory effects
  • Anti-carcinogenic effects
  • It is beneficial in patients with diabetes because it prevents a sudden rise of blood sugar levels after a meal.

Studies have shown that citrus fruit reduces the risk of breast cancer.1

How the Citrus diet leads to weight loss?

Citrus fruits contain citrus acid that stimulates the secretion of juices and enzymes in the stomach and these regulates digestion. By regulating digestion, the Citrus diet will help your body to utilize nutrients that lower fat absorption which reduces the creation of unnecessary calories in the body. In addition, poor digestion leads to a listless and depressed mood where many are less physically active.

Lemon and orange contain plenty of pectin (a well-known dietary fiber), which fights against hunger and plays an important role in improving the digestion and removing unwanted substances from the body.

A cup of warm water and lemon juice make an excellent energy drink and a "shot" of vitamins.

The disadvantage of the Citrus diet is that because of the extremely low caloric intake, it is likely that you will often experience headaches, fatigue and exhaustion. Do not remain on this diet for more than a month.

The advantages of the Citrus diet are that it is cheap, easy to handle and highly effective.
