Lifestyle change (updated)

[Jaytee]

Hey guys. Been trying to get into the gym and losing weight for the last few years. But its taken till now to realise that a string of yo yo diets and occasional gym sessions just won't cut it. Last month i made a lifestyle change. Had a few hiccoughs and its been a slow start but its not something that can be done over night. Anyway heres the facts.
Im 5'10 and currently 263lbs down from 270 at begining of january. Aiming to get down to 175lbs and then start from there. Im under no illusion that once i drop the weight im gonna have an amazing body but that i feel would be a good base to start getting some muscle and definition. Im hoping to acheive this target weight by xmas this year. This is what im doing at the moment.
Chest/tris
Back/shoulders
Biceps/cardio
Legs
And some sit ups and stuff at the end of every other session.

Diet
Breakfast - 3 poached eggs 2 slices of wholemeal toast/ bowl of porridge with peanut butter
Coffee s/s milk 2 sugar

Lunch - 2 poached egg on toast (obvs not if iv had it for breakfast)/ chicken breast with salad or tuna with salad or something similar.

Snack - banana

Dinner- pasta and chicken/ bolagnase/ clean home made curry.

Snack - 2 ryvita with cottage cheese.

2-4 litres of water
Maybe 2 cans of diet coke or 2 cups of coffee. I have stopped drinking for now as well. Probably going to have one night out a month as. A treat but not go mental.

Is this a good diet plan?
Basically looking for any advice or critisism. Thanks guys. Hopefully il update every month with my progress. Thanks guys.
