Ruby Red Grapefruit Juice Diet

Updated on April 18, 2011


I am sure you can incorporate red grapefruit in many ways in your diet plan. Recently a friend of mine successfully tried a simple but very effective ruby red grapefruit juice diet. While I am aware that every one of us has a very individual metabolism and that each type of weight loss plan should be adjusted to match it, this grapefruit juice based diet plan is simple enough to be easily followed and applied in everyday life.

Here we talk about a combination of negative calorie foods and grapefruit juice which are to be consumed following a broad diet plan indicated bellow. The most important thing about this weight loss plan is that when you choose to terminate it, you won't regain the excess pounds, which is (unfortunately) often the case with so many overly restrictive plans that can be found on the internet.

The pros and cons of red grapefruit

What is so special about ruby red grapefruit vs the white or pink colored variation (these colors refer to internal pulp color)? Here is an article from the Science Daily website about red grapefruit health benefits. Supposedly, "A grapefruit a day — particularly the red variety — can help keep heart disease at bay, according to a new study by Israeli researchers... " You are welcome to read the whole article, as it is highly informative.

On the other hand, I should warn you right here, and give you a link of a study about the possible health risks of regularly consuming grapefruits on a daily basis, especially when it comes to increased risk of breast cancer. Grapefruit juice has also some interactions with a number of medications, so if you are under therapy, make sure you consult your physician.

In any case it appears that the red variety of grapefruit is more beneficial than all the rest varieties.

Grapefruit Juice in Combination with Negative calorie foods

This specific diet consists in eating more of the following foods: celery, carrots, apples, tangerines, broccoli, mushrooms, asparagus, beets, cabbage, cucumbers, blueberries, spinach, pineapples, strawberries, lettuce and cranberries. You are allowed to eat as much as you like, provided that your diet is mostly consisting of these specific types of foods.

Why is it allowed to consume unlimited quantities of the above ingredients? The answer lies in the number of calories required for their decomposition by our body, which is much larger than the number of calories they provide. (While there is actually no scientific proof that there are negative calorie foods at the first place, this is a very popular concept which is generally considered to be true.)

For example, celery has 6 kcal in one medium stalk, and it requires approximately 50 kcal to be digested. So, your body consumes 44 kcal taken from your fat deposits to break the celery down. The other example would be tomato which has 26 kcal and your body needs 60 kcal to decompose it. So there you have an excess of 34 kcal burnt, reducing your fat tissue.

This mathematics might be wrong, since our body is not a machine. Do not go over your head with counting calories. Even if the calorie difference is not correct, foods like celery, apples or asparagus are extremely healthy, and they will certainly help in both losing weight and leading a healthy life.

You are also allowed to consume other foods, given that you can restrain yourself and eat moderately. The only requirement is that after your meals you take one cup of raw squeezed Ruby Red Grapefruit Juice, or alternatively one raw red grapefruit. The third option is to drink a glass of quality organic red grapefruit juice purchased in a healthy store.

Consuming red grapefruit after your meals is important! Grapefruit helps lower the level of blood sugar as well as prevent the newly taken fats from depositing in your body.

I emphasize that all the above listed foods are to be consumed as much as you like and whenever you like. In addition, you are not limited to be totally deprived from other foods either. But my recommendation are to dismiss any kind of sweets, deserts and in fact anything that contains white sugar in it. This also means, not to eat chocolate, as well as snacks and drinks that contain sugar. Water, tea and coffee with milk but without any sugar or artificial sweeteners can also be recommended.


At the end, is ruby red grapefruit juice good for weight loss? Definitely YES. The only requirement is to be moderate with caffeine, not to spoil the beneficial effect of the grapefruit juice, so take only one to two cups of coffee a day, no more! When you decide to abandon this weight loss plan, keep consuming one glass of ruby red grapefruit after your meals and that's it. The fatty deposits are likely not be regained ever again. The friend of mine from the beginning of this hub managed to loose 30 pounds in 6 weeks following just this simple diet plan, and she still maintains the weight obtained after this ruby red grapefruit juice diet.

      Hi Eduardo,

      You are right. Grapefruit, Grapefruit juice and Bitter oranges are known to inhibit the metabolism of statins. Here is the link to a Mayo Clinic article ( if you are interested to read more about this interaction.

      Typically statin drug prescriptions warn to not consume any grapefruit with such meds. Why is that?

      The red variety has somewhat more calories, but also higher concentrations of antioxidants than the white grapefruit. The same is true also for lycopene, an anticancer ingredient. So when when shopping for grapefruit, it is slightly better to go for the red or pink variety.
