Your guide to weight loss with the 5:2 Intermittent Fasting Diet

Grapefruit and Coffee Fat Burning Mix

5:2 Diet Meal Plan

While on a diet like the 5:2 Fasting Diet, your goal is most probably to lose some of that extra fat, right? Well, here’s a suggestion that you may not have heard of before that you might want to consider – the grapefruit and coffee combination.

With the Fasting Diet Plan, we limit the calorie intake two days a week, which helps your body burn off more fat than normal. But if you want to go beyond just limiting calories, and start planning to add fat BURNERS into your diet, there is no easier way than the grapefruit and coffee combo.

We know that Grapefruit is already an excellent low-calorie food (and high in vitamin C) and that black coffee increases your metabolism (the energy and ‘jittery’ feeling you sometimes feel after drinking coffee), but when you combine these two, you get a fat burning monster.

Grapefruit is an excellent low-calorie food and coffee increases your metabolism. Give grapefruit and coffee a try

This idea was made popular after The 4-Hour Body book came out, publicizing to a large audience the benefits of drinking grapefruit juice with coffee.

The basic concept is that certain enzymes in the grapefruit help increase the half-life (or length) of the coffee’s fat burning/metabolism increasing effects. Essentially, combining these two drinks (or a solid grapefruit if you have time!), is like drinking extra coffee for the metabolism increase, but with the added bonus of the nutrition of the grapefruit.

Try it out for a while. I really like the taste of a black coffee after a big glass of grapefruit juice.


NOTE: If you’re going to try this grapefruit and coffee combo with grapefruit juice from a bottle or carton, definitely do your research at the market, as many grapefruit juices are not pure and made from concentrate with lots of added sugar. Try to find one that lists the grapefruit and water as the first two ingredients.

Bonus if you can find pure grapefruit juice with no added sugar. Also, watch the calorie count on the juice if there is added sugar. If you have access to fresh grapefruits and juice your own, then this would be the best way to go.

    Hey, are you sure any kind of commercial grapefruit juice is effective? After all, if it’s in a bottle it’s been pasteurized, heated, cooked. Enzymes are destroyed by heat. So, bottled or canned grapefruit juice may just be empty calories.

      Hi Delphine,
      Thanks for your question. Canned fruits and juices provide similar amounts of vitamins and minerals compared to their fresh equivalents. Fruits are usually frozen or canned very soon after harvesting,locking in their nutrients so the vitamin and mineral content is preserved. However you are correct in saying that many commercial fruit juices may not be as healthy or effective. Just the same as not all fats, or sugars or types of breads are equal neither are fruit juices. Many commercially made juices whose primary ingredient is ‘made from concentrate’ will most likely have had many of the health benefits stripped back and possibly have a lot of added sugar. So doing your research when at the grocery stall is advised. Check out the labels of the fruit juices and aim to get freshly squeezed with the pulp and good stuff still contained within and make sure there is no added sugar.

      Yes you are correct if you do not take the time to look at the quality of the juice you are buying then perhaps it can be viewed as ‘just empty calories’. Thank you for brining this important fact up and making as all aware to be more conscious of the juice we are buying and to always go for fresh is best!

    really useful – thanks
    I’m going fresh direct from the fruit

      Yes I tend to agree – like most foods fresh will always be better

      Hi Helen, Glad to hear that you tried this fat burning mix, it’s a little unusual but if you are prepared to kickstart your day and can stomach the acidity of the grapefruit and the black coffee it can be a powerful mix.

      I have grapefruits in our yard that grow the size of a softball so eating fresh grapefruits without the added sugar is easy for me to do. Remember use fresh grapefruits or juices that have no added sugar ( I personally believe fresh is best as the enzymes will be at the optimum levels)

      To your health
