No caffeine?! Without it, I would cease to function. I've been trying for ages to reduce my consumption but whenever I find myself at a nadir, a project comes up, and so does my caffeine intake. I doubt I'll ever be able to kick the habit. For better health reasons, I've begun to shift from caffeinated sodas to tea--in order to reduce sugar intake. But thank you for your advice. Now, time to go and buy a few boxes of Twinkies and stuff my face. Nom nom nom. Just kidding. Your advice corroborated things that I've been doing so it reassures me that I'm on the right path. I just wanted to see if I could squeeze some double-secret advice out of your.

I rule out caffeine because it restricts blood flow needed for breast growth and may inhibit aromatase, It will seem hypocritical when I give you the rest of this info, so the decision is up to u all. For the "Double Top Secret Advice", you need to sign the waiver, lol. Seriously though, I do have a list, but why risk it.

A study in the October 2001 issue of "Fertility and Sterility" found that more than one cup of coffee a day increased estrogen in women between the ages of 36 and 45 in the first stage of the menstrual cycle. In a study reported in the June 2005 issue of "Cancer," caffeine intake decreased estradiol, one of the forms of estrogen, during the luteal phase of the menstrual cycle. Both caffeinated coffee and caffeinated tea had this effect. The researchers thought caffeine might inhibit aromatase, a key enzyme in the production of estrogen in the body.
(That's a biggie right there).

In a study of 269 women, researchers took measurements of hormone levels across two menstrual cycles, while repeatedly recording how many caffeinated drinks the women were consuming. Interestingly, they discovered that caffeine affects estrogen levels differently among women of different races. Moderate daily caffeine intake—about two cups of coffee or 200 mg a day—lowered estrogen levels among white women, potentially offering protection from diseases linked to higher estrogen, such as reproductive cancers. On the other hand, Black and Asian women who drank the same amount of caffeine experienced elevated estrogen levels.

Even though caffeine can boost your metabolism in the short term, this effect is diminished in long-term coffee drinkers due to tolerance.

However, coffee for men....

The ingestion of 300 mg of caffeine prior to food intake, compared to placebo, was shown to significantly reduce energy intake by 21.7% in healthy men, but not in women.

Caffeinated coffee does not acutely affect energy intake, appetite, or inflammation but prevents serum cortisol concentrations from falling in healthy men.

Data suggests that ACTH-induced suppression of testosterone is due to an action of cortisol.

Bottom line:

Coffee raises E in women, especially in the first few days of the luteal phase (4 cups)
In men Coffee lowers Testosterone by way of cortisol (which part of T, I'll get back to ya).
