I've decided I want a sleeker, slimmer body so have started at the gym like I used to. If I go four times a week, each session an hour and a half with a mix of cardio and weight training how long before I start seeing results and how much weight should I lose? Please answer my questions nothing else, tanks x

Depends on how you eat... If you don't lower your caloric intake, your wasting your time

BE ANOREXIC!!! DON'T DRINK THE ENSURE!! KENNYYYYY!!!!!

I personally believe that you have probably already seen results. Don't measure results just on pure weight loss, think about how you feel and the tone and shape of your body. Your body is made up of many different elements, around 70% water of course, muscle is also heavy and therefore measuring your fitness improvement purely on the scales is folly.
