-not all meat is bad for this either, poultry is fine, its mostly the really heavy stuff like beef that's a problem, and idk about eggs
Poultry is very good for you, especially if you cook it by steaming. This avoids a lot of fat.
A good healthy meal is a portion of steamed chicken, alongside rice and steamed vegetables. And it's not particularly expensive.
There's no need to go completely vegetarian if you're trying for a skinny/lean build.
Eggs are also good for you too, provided you avoid things like over-salting them.
And if you want some form of meat, then fish is very good. Most fish is high in essential oils, which will be generally good for your body, but also your skin.
You have to remember that with a diet the entire thing is about moderation. It's exercise that will be helping you to lose weight most effectively.
And to be honest, if you're changing your diet solely for oestrogen consumption, I think you'd just be better off going on to some form of hormone therapy.
I can't imagine diet providing such significant amounts of oestrogen. But I may be wrong. I'm not a doctor or a dietician.
