Hi just joined this thread too. I believe taking caffeine also leads you to skinny form.

Like My problems i have a skinny body, less eating habit and love caffeine drinks a lot, and every night during sleep my body will feel very hot like it is burning(please dont mention about sins lol).

Should I check my metabolism rate first? Some of my friends said thyroid also causing you loss weight but when i go to clinic the doctor said i don't have thyroid anymore.

Now I'm practising eat every 2hrs normally eat bread and butter cookies but until now my weight is 43kg with 170cm tall. So frustrated.
