I think I need some help
 

Right so I've gone from nearly 18 stone down to 13 through dieting and just eating right. Now I'm trying to get myself in shape, I'm still not at my correct weight for my height (I think I should be around 12ish stone)

I've started with a personal trainer a few times a week to work on toning and building muscle but I'm struggling. I've come to to the conclusion that I just can't lose fat with a low calorie diet and work on building muscle.
I went to the gym last night for a session having only taken in around 1200 cals (I know, I know) I ended up failing half way through and started feeling dizzy, I kept pushing myself and ended up getting sick and just shut down.

My question is this; is there anyway of balancing the two or can I only focus on one goal at a time? Should I lose more weight first before I hit the gym to build myself or should I start now and cut weight when I have the muscle mass?
How many calories should I be taking and how should I be structuring them?

I'm currently taking in between 1200-1500 with a good balance of lean protein, complex carbs, greens and good fats, I make my BMR to be around 1900cals

google calorie calculater and fill in the details and it will tell you how many calories you need a day

but 12-1500 cals is not enough if your going to the gym aswell

well done on your weight loss so far :clap:

Well done buddy. I am in the same situation but currently at the 18stone end not the 13 but I will get there!

I know this is old, but if your BMR is 1900, eating 1200-1500 cals is really not good.

Super low calories will only make your body go into 'safe' mode. You'll have no energy for training and it'll be awful.

The better way to do it is to calculate your TDEE, return to that for a few weeks, monitor your weight, then once it stabilises, decide if you want to lose weight or gain weight and make the changes MUCH more gradually.

A calorie deficit diet will help you and yep you will need a calculator for that. Just monitor your calorie intake and work out,
