Grapefruit and Weightloss
Eating half a grapefruit (or drink 8 ounces of grapefruit juice) may block
enzymes involved in
carbohydrate storage, and speed up the way our
bodies burn fat, resulting in
weight loss. The Grapefruit Diet usually lasts
about 12 days, but if you want to continue, you must take at least two days off
before doing so.
Providing no more than 800
calories a day, the grapefruit diet menu involved
eating lots of 'fat-burning' grapefruit to kick-start your
daily protein (mainly boiled eggs) and the odd piece of dry toast.
Besides, grapefruit sparkles with health promoting compounds that may help:

Grapefruit is low in
calories, low in
sodium, high in
and high in fat burning enzymes benefiting weight loss in different ways.
The low calories means you can eat grapefruit freely without consuming too
many calories. A low sodium intake helps flush away excess
water weight caused from high
sodium foods. And, the enzymes present in grapefruit help increase fat
The 12-week pilot study, led by Dr. Ken Fujioka, monitored weight and
metabolic factors, such as insulin secretion, of the 100 men and women who
participated in the Scripps Clinic 'Grapefruit Diet' study. On average,
participants who ate half a grapefruit with each meal lost 3.6 pounds, while
those who drank a serving of grapefruit juice three times a day lost 3.3 pounds.
The research indicated a physiological link between grapefruit and insulin.
According to them the chemical properties of grapefruit reduce insulin levels
and encourage weight loss. The smaller the insulin spike after a meal, the more
efficiently the body processes food for use as energy and the less it's stored
as fat in the body.
Another positive benefit of eating
grapefruit is the high water content. Grapefruits are almost 90 percent water.
Eating any fruit with a high water content helps boost water ingestion and
research has shown that increasing water consumption can give more energy and
help increase the metabolism.
If you enjoy grapefruit, it's certainly not going to do you any harm to eat
it regularly, in moderation - but make sure you still include plenty of other
fruits and vegetables in your
diet as well. Grapefruit has no fat, is low in
calories and sodium, is packed with
vitamin C, and the pink variety contains
beta-carotene. Grapefruit can be part of a healthy eating plan, but because it's
good food, not because it does anything special with burning fat.
Grapefruit Diet and medication
Large amounts of grapefruit can interact with a number of medications,
potentially causing serious side effects.
Grapefruit ‘works’ by inhibiting an enzyme in the intestines that’s responsible
for the natural breakdown and absorption of many medications. When the action of
this enzyme is blocked, blood levels of these medications increase and this can
lead to potentially toxic side effects. If you’re taking any medications you
might want to speak to your physician first, before eating lots grapefruit to
boost your weight loss.
Twenty years of nutrition advances have taught us that eating a wide range of
foods is the best way to lose weight. As always, if you want to shift those
pounds safely and keep them off for good, you should never go below 1,100
calories a day or follow an unbalanced diet that restricts the majority of foods
while encouraging vast quantities of just a few.
