I just wanted to share some experience. I have been since april 2015 really thinking that i should transition( thinking of it since im 12 year old) but was only sure about it on july 2015. However, my head kept telling me that i should start to prepare in case i decide to transition.
so back in april my weight was of 176 pounds with around 8% bodyfat at 5.8ft . All i remember of my size is that my arms were 17 inch .
i took first measurements on july 3rd 2015 :
159 lbs
37-37.5 inch chest
32 inch underbust
30.5-31 inch waist
37 inch hips
14.75 inch bicep(flex)
12.75 inch bicep(rest)
14.3 inch neck
13.5 inch calve
11 inch forearm
6 inch wrist
22 inch thigh
38 inch butt
Then this is today oct 6th 2015:
149 lbs
34 inch chest
30.5 inch underbust
28 inch waist
36.5 inch hips
14 inch bicep ( flex)
11.5 inch bicep (rest)
14 inch neck
14 inch calve
11 inch forearm
6 inch wrist
21 inch thigh
36.5 inch butt
How i achieved this?
I think genetic plays for a lot, before doing bodybuilding at 17 yo i remember that my weight was 128 pounds very skiny. In my case my body type morphology is mostly ectomorph . you can read about that here :
http://www.bodybuilding.com/fun/becker3.htmWhat i did is i completely stopped doing any muscular activity except abdominal and i continued doing some "butt training" ( squat, lunges, side lunges, leg press) avoiding any exercice that would maintain my quadricep muscles.
I also started doing long cardio session of 20-30 minutes 5 time per week.
For food, i wont tell you what i did and i dont recommend it for your health. However i changed my diet from 6 meals per day to 1-2 meals per day , eating something high in sugar right after the gym to "accelerate the metabolism" for muscle loss. Ive been cycling from almost not eating to eating a lot for a few days just to gain more fat to burn. I think that by doing this, it helps to burn muscle along with the "tempory fat" you took.
Well it seems to work for me. I cant wait to see what will happen when my system will carburate with oestrogen .Meeting with endocrinologist in 2 days

Just keep in mind, it is not because you arent approved for HRT yet that you cant prepare your transition by growing your hairs and losing muscle .
