gain in inches

ok, im on weight gain mission as im a recovering anorexic. I have upped my calories to 2500 and only focussing on strength training exercises at the gym. i do walk to and fro from work, which is about 2miles a day.

this i have been doing for two months. my personal trainer measured me and i ve gained an inch on my waist and also around the bust, (my clothes at the top feel tighter)!!

my weight has increased to an addtional 2.5 pounds.

im really worried whether the inches ive gained are muscle or fat?? is there anything i can do to change this??

all your thoughts will be appreciated!

if you are in recovery from an ED you will gain fat.  You have to.  Your body is recovering and fat is essential for health.

As for how much fat you gain...its mainly genetic.  But your training and food intake can play a role.  The fact that you are weight training means some of it is muscle.  How much...only way to know for sure is to get periodic DEXA scans (body scans that measure lean body mass and fat).

Honestly, I just wouldn't worry about it.

And even then the DEXA waiting list is looooong.

As said you have to gain some fat. Also, if you're working out, you really need to increase more. Is that gain of 2.5lbs over those two months because seriously, that is really too slow. A recovering outpatient should be gaining approximately 1lb to 2lbs a WEEK.

You'll be gaining muscle (from the strength training) and fat (which is essential for your body to be healthy) and water (because muscles hold water) and blood (because as you get a bit bigger you need a bit more blood in your body).  If you are eating well and working out, you won't gain an unhealthy amount of fat.  Your body knows what it needs right now, so relax and have faith that anthing you are gaining is weight to make you healthy, don't try and distinguish whether it's fat, muscle, water, blood, or whatever, that's probably going to drive you crazy.
