If you're not in the process of transitioning, I don't see why you shouldn't use the leg press machines, leg curls and leg extension machines, and the abduction/adduction machines at least once weekly to exhaustion in addition to diet. Putting on muscle on the lower body will help balance out the typical, "top heavy" male stereotype that people look for first at a glance to determine gender. It will also increase your metabolism so you're burning calories around the clock instead of just when you're on a cycle or treadmill.
Get red meat out of your diet entirely.
Kick beef out of your life. Save it for special occasions only, or once every two weeks. If you want a burger, use soy burgers and go to
allrecipe.com and learn how to cook them. Don't say you haven't got time to cook either, I work 50 hours a week and take 5 classes a semester and cook a healthy diet and work out, so you can too.
Since you're NOT on hormones yet, focus on a high protein diet but use healthier sources of protein: soy, turkey, fish, chicken, sources low in cholesterol which has androgenic effects on the body.
Once you get on hormones, switch to a high carb low protein/fat diet.
Then again there's also a new diet craze of eating ONLY fats, poly and monounsatterated fats, thus teaching your body to utilize lipids as an active energy source instead of an energy storage device. What that will do, supposedly, is burn fat off of you like a cigarette held next to a gas pump. You can read more about that here:
