You do this for a few days and then you start changing your cooking habbits. This was a year ago and I've held the weight since and simply started eating less. My old eating habbits did not make me gain weight though as my old weight was constant for 10 years.
My main liquid is 98% water. I cant stand soda unless its mixed with 90% water.
There's a huge variety of tastes among green teas, white teas, oolong, black teas... Specific tea variety, different locations where the plants are grown, different manipulations, all concur to a lot of different tastes. However, a lot of people I've met just say it tastes like "earthy/dirty water"
But also, you can stay sufficiently hydrated by drinking just tea. Trying that with coffee will skyrocket your caffeine intake to unhealthy levels.
And a lot of those are not "tea" (with theine/caffeine), they're herb infusions such as mint, hibiscus, chamomile, etc. You can drink as much as you want without getting the typical caffeine buzz.
I particularly like the Morocco Mint & Spices that Lipton sells.
Caf: Turkish Caykur Rize tea with a tiny bit of sugar or honey, and boiling water.
