Paleo Diet

The last word grapefruit information

Another day, another diet. There are probably as many diets in the world as there are days in the year. And diets always seem to get people looking for nutritional advice. That's why we want to provide you with the information you need to know which diets are safe and sustainable and which may not be. This week we will focus on the grapefruit diet.

The intent of the grapefruit diet is rapid weight loss. It is a short term diet where you eat grapefruit with every meal. Her other meals include eggs and high protein meat. Besides some vegetables, fat is also a factor in diet.

The principles behind it don't seem particularly promising. Eating grapefruit with every meal should do nothing more than add grapefruit worth calories to the dish. However, this citrus contains fat-burning enzymes, so the results might be plausible.

In this ultimate grapefruit guide, we're going to explore:

  • What is the Grapefruit Diet?
  • Grapefruit benefits.
  • Advantages and disadvantages of the grapefruit diet,
  • Grapefruit Diet: Daily Meal Plan.
  • Does the Grapefruit Diet Work?

What is the grapefruit diet?

There are variations on this diet. We focus on the most popular version.

The grapefruit diet is a meal plan in which you consume grapefruit products and high-protein foods at every meal. Unlike many diets that involve lifestyle changes (Paleo, Keto, Vegan), this plan only lasts 12 days.

However, with this diet, you are consuming less than 1,000 calories per day. Some suggest around 800 a day, but we recommend staying as close to the cap as possible. You should also drink plenty of water (and a tea or coffee) each day to keep you feeling full.

This is most likely when the extreme weight loss occurs – a significant calorie deficit.

That said, grapefruit can help you lose weight. This study shows that a group that consumed grapefruit lost more weight than groups that did not.

But in 12 days, a majority of the weight loss will likely be water weight – you cut off a lot of what makes you hold back fluids like carbohydrates.

This is probably not a diet the results of which you can sustain unless you follow another program of general lifestyle change for weight loss.

Grapefruit benefits

What other benefits do grapefruits offer besides the quick results on the grapefruit diet?

Weight loss benefits

The main benefit is weight loss and faster metabolism. The latter comes from the vitamin C content in grapefruit. The former comes from the supposed fat-burning enzymes, but the increase in metabolism may have more to do with it.

This essential nutrient is also linked to lower body fat in the long run, not just on these short diets.

Other benefits of grapefruit

Advantages and disadvantages of the grapefruit diet

So far, there seems to be hardly anything wrong with this diet. There may be limited research, but the results are positive. Especially the surrounding vitamin C – the benefits of which alone make a great addition to any diet.

However, these advantages are offset by some disadvantages.

Side effects of the grapefruit diet

Fortunately, the side effects don't come from the grapefruit itself – it's just the drug interactions.

The grapefruit diet is incredibly restrictive as you stick to fewer than 1,000 calories. The side effects of not eating too much are:

Fortunately, some of these side effects are only due to long-term, super-restrictive diets. Others are only associated with extreme calorie restrictions – for example, women's common cold, which consumes 400 calories a day.

Regardless, undereating remains a risky endeavor and can prove problematic.

Drug interactions

Other drawbacks point to the drugs that grapefruit collides with. These are according to the FDA. The way the grapefruit interacts is different.

  • Cholesterol lowering drugs such as atorvastatin, pravastatin, and simvastatin.
  • Blood pressure drugs, nifedipine.
  • Antihistamines.
  • Anxiety drugs.
  • Medications that prevent your body from rejecting organs after a transplant.
  • Certain drugs used to regulate the rhythm of the heart.

Grapefruit Diet: Daily Meal Plan

Finding out what to eat on such a restrictive diet can be a challenge for you. You know you need grapefruit, but what else? High protein foods like …?

To help you, we have created a menu that shows you what types of foods you should eat with grapefruit.


  • Two boiled eggs for the protein content.
  • Two slices of bacon for the fat.
  • Half a grapefruit or a glass of grapefruit juice – grapefruit in its pure form is best.

Having lunch

  • Salad, preferably with the dressing of your choice.
  • Any meat as much as you want – think about the 1,000 calorie goal.
  • Half a grapefruit or a glass of grapefruit juice.


  • Meat as much as you want. The type does not matter here either.
  • Salad or vegetables – choose the colors green and red.
  • Your choice of grapefruit or Grapefruit juice.
  • Tea or Coffee – Coffee is a thermogenic fat burner, as is green tea.


  • A glass of skimmed milk.

Does the Grapefruit Diet Work?

Given the facts, one has to wonder whether this works or not. It is a difficult thing.

You will lose weight on this diet. The calorie reduction ensures that.

Grapefruit has some fat burning properties.

But you eat a lot less than usual, which will be the main competitor in losing weight. Drinking plenty of fluids can also help you curb hunger pangs from decreased food intake, and grapefruit is high in water.

Yes, the diet can work – but it is unsustainable and too restrictive. You don't have time to lose a ton of body fat and you can regain it all by eating normally again.

In short, the diet might be ideal for losing weight before an event, but not for losing weight over the long term.
