One thing that has not been mentioned so far is progesterone, which you might want to consider adding to your regimen if you're not taking it already. This is mainly what makes pregnant women gain so much weight. Many American TS women are put on an estradiol-only therapy and unfortunately do not get to experience the added benefit of progesterone. This includes better fat distribution, rounder breasts, far better skin, moderate antiandrogenic effects among others. I might write a separate post about this eventually, but basically in my experience, a combined therapy works much much better, even if you're taking pure anti-androgens. I started out taking both estrogen and progesterone, had fantastic results (though age and genetics will also play a role), then went to a different doctor who put me on estrogen only. The differences were almost immediately noticeable in my case: oilier skin, breakouts, weight loss, hair loss... basically a 50% return to my pre-transition days. I was devastated until I finally figured it out. As soon as I returned to my old regimen, things were back to normal.
Also, eating such an unhealthy diet will backfire as you get older, and could give you dull, unattractive complexion. Not to mention high cholesterol levels, risk of coronary disease, etc. Eating healthy fats (Canola, Olive, etc.) will not make you gain weight either, that's a misconception. Do drink plenty of whole milk/natural cream, eat whole yogurt, breads, cookies, cakes, pies, other rich baked items, jam, peanut butter, ice cream and chocolate; ALL with natural, simple ingredients (no hydrogenated oil, margarine, high fructose syrup). Butter is good. Drink plenty of natural juice, eat a lot of bananas and potatoes (unless you're on spiro), add rice, beans and nuts to your diet, and gradually cut your meat/chicken intake by half (or go vegetarian if you could).
