Grapefruit juice: friend or foe?

[Faust]

I've read somewhere that grapefruit juice slows your digestion down (apparently it disables certain digestive enzymes), and that's why some people are advised to take their medication with it, so it absorps better.


My question: could i use it to give my meal a lower gi ?
For example, if i have a high gi meal (like white bread or something), if i drink grapefruit juice with it, could it turn out moderate gi, due to slower digestion.
And if i take my supps in the morning, would they be absorped better?

Its good to take methylated steroids such as D-bol or anadrol with grapefruit juice.

Fat and protein are what's going to change / lower the GI (learn more about GL too).  Grapefruit juice does seem to have an insulin lowering effect.  Most supps are absobed best with food

Alright, but how does this "lowering" of insulin happen? Did they research blood sugar levels as well. I get the idea that the research behind these kinds of things is not done properly most of the time.
Maybe insulin levels are lower because of a slower instream of glucose.


I'm reading up on it a bit now. Apparently it disturbs certain liver enzymes, so certain chemicals (like steroids and statins) get broken down slower. But it's good for your cholesterol and weight loss. Lower insulin levels can't be bad either.

In high school we ate grapefruit for breakfast cause they said it shrank your stomach walls from the acid and made it so you didn't as much.  That's what our wrestling coach said.

I don't think they know yet.
 
 29/01/2004 - Eating grapefruit, long recommended by diet programmes for weight loss, may indeed impact the body’s insulin levels, speeding up metabolism and leading to weight loss, say researchers from the US-based Scripps Clinic.
In a 12-week pilot study, led by Dr Ken Fujioka from the clinic's Nutrition and Metabolic Research Center, researchers found that people eating a serving of the citrus fruit with each meal led to an average weight loss of 3.6 pounds.
About 100 male and female participants, who had an average weight of 218 pounds, were divided into three groups. One ate half a grapefruit with each meal, a second was instructed to drink a serving of grapefruit juice three times a day, and a third acted as a control group. The study participants maintained their daily eating habits and slightly enhanced their exercise routine.
Those eating the fruit three times daily lost on average 3.6 pounds over the study period, while those on the juice regime lost 3.3 pounds. The control group only saw an average decrease of 0.5 pounds.
Some of the patients taking grapefruit lost more than 10 pounds, added the researchers.
“For years people have talked about the grapefruit diet, and some even swear by it, but now, we have data that grapefruit helps weight loss,” said Dr Fujioka.
The study also indicates a physiological link between grapefruit and insulin. The researchers speculate that the chemical properties of the fruit reduces insulin, seen in measurements of the participants' glucose levels.Insulin is known to help regulate fat metabolism and also plays a key role in diabetes. The finding means it could also protect obese people from developing type 2 diabetes. However lowering insulin levels also makes people feel less hungry and this could also explain its link to weight loss.
Grapefruit is already known to affect the metabolism of some drugs, by impacting the enzymes needed to break down common medications.
The researchers are planning a much larger study to see if the results can be confirmed.
3.6 lbs in 12 weeks!  Wooohooo

A new supplement DHB is supposed to increase the effectivness of all supplements and meds you are taking.  I have used it and it works, but in 300 gr doses, not what is usually put in a sup which is anywhere from 10 mg to 25 mg. and once again people think it dosen't work because they are underdosing.  Back to Grapefruit, the main ingreedent in DHB is 6', 7'-dihydroxbergamottin which is derived from grapefruit, but much more concentrated.  I and many of my friends have tried it and all say it works.  It's not a bomb, but using 1/2 does of creatine and feeling like you did 2 doses is nice.  With meds it works the same way   give it a try.
