Hie there.

First of all, do you go to the gym for your workouts? What is your aim for now? Cutting or bulking? But seeing your current weight, I would assume you would want to cut right? So go for full body workout. Get a starter program. Look at the stickies posted or search at www.bodybuilding.com
Get the correct programme for your workouts so that you can achieve optimal gain.

On your daily meals, try posting your daily meals first and we would comment on it.

50 reps of dips for a beginner?

50 dips 1 set ? would be impressed .. but anyway , doin negative reps always good ?

Wats ur overall program looks like?

dont cut down meals severely.. if ur trying to build ur body, meals must not be cut down.. otherwise it's the same as running a car without petrol..
