Caffeine when cutting water

[barney10]

I have a photoshoot coming up in about a week and am currently carb depleted but drinking a lot of water. 2-3 days before the shoot I plan to carb up and decrease water intake
Question is should I be using caffeine during depletion to keep my energy up and decrease insulin sensitivity or use it during carb up as a mild diuretic? Or both?

First time I've tried this so I don't expect to have got it perfect but if you got any tips that would be good

Abstract
BACKGROUND: Caffeine and related methylxanthine compounds are recognized as having a diuretic action, and consumers are often advised to avoid beverages containing these compounds in situations where fluid balance may be compromised. The aim of this review is to evaluate the available literature concerning the effect of caffeine ingestion on fluid balance and to formulate targeted and evidence-based advice on caffeinated beverages in the context of optimum hydration.

METHOD: A literature search was performed using the Medline database of articles published in the medical and scientific literature for the period of January 1966-March 2002. Subject headings and key words used in this search were: tea, coffee, caffeine, diuresis, fluid balance and water-electrolyte balance. A secondary search was performed using the bibliographies of publications identified in the initial search.

RESULTS: The available literature suggests that acute ingestion of caffeine in large doses (at least 250-300 mg, equivalent to the amount found in 2-3 cups of coffee or 5-8 cups of tea) results in a short-term stimulation of urine output in individuals who have been deprived of caffeine for a period of days or weeks. A profound tolerance to the diuretic and other effects of caffeine develops, however, and the actions are much diminished in individuals who regularly consume tea or coffee. Doses of caffeine equivalent to the amount normally found in standard servings of tea, coffee and carbonated soft drinks appear to have no diuretic action.

CONCLUSION: The most ecologically valid of the published studies offers no support for the suggestion that consumption of caffeine-containing beverages as part of a normal lifestyle leads to fluid loss in excess of the volume ingested or is associated with poor hydration status. Therefore, there would appear to be no clear basis for refraining from caffeine containing drinks in situations where fluid balance might be compromised.

^^^from the study: you quickly develop a tolerance to the diuretic effects of caffeine, within a matter of days actually. If you plan on using it as a diuretic you've got to eliminate caffeine from your diet then use it in doses of at least 250-300mg to achieve increased short-term stimulation of urine output for a couple of days. Needless to say the diuretic effects of caffeine are grossly overstated by the general public. You'll probably notice a more profound effect from decreased fluid intake, decreased carb intake, and limiting or eliminating sodium from your diet.

When I have am in the postion you are in and I'm incorporating water depletion, sodium loading/deloading and carb depletion methods I will use dandilion root, for me it sucks the last bit of water out.

Yeh my lecturer said the same thing about caffeine. Thanks

I might give dandelion root a shot next time then. I noticed the watershedding supplements all contain it

I did two and a half days cutting back water and it was two much. How many days do you cut back on water normally?

Your body won't build tolerance to dandelion root extract like it would caffeine as well but as Prisonsex said its the last little bit. How much water were you drinking and how much did you cut to for those 2.5days? How big are you?

you have to take limited amount of ingredients in your diet, it will help in maintaining the body growth.
