Resolved Question: I have two questions about tea.?

Recently Teavana has moved into a location near me and before that, I was never really a big tea drinker. I had a few cups of green tea a month from tea bags but that was it. But after sampling Teavana's tea I was hooked. I bought some mate and oolong (wu-long) tea for weight loss benefits and loved it. But my now problem is that I'm hardly ever home except in the morning and at night so I don't have a lot of time to spend heating water, steeping tea, and then finally relaxing to drink it. Which leads me to my questions:

1. Is it safe (and effective) to just eat the raw or steeped tea leaves and get the same benefits that oolong and mate teas boast about?

2. What is better for weight loss / hunger suppressant between mate, oolong, and green tea?
