What you put in is what you get out.
A liquid lunch in the pub is just not the way forward, desert every day of the week is asking for trouble, smoking is like suicide in instalments.
Enjoy your food but eat sensibly, put some colour on your plate & mix it up. be it at home or on the go in the city at work.
Ask yourself what you want with your fitness goals & the impact on the type of foods you're about to eat will do for you.
Keep track of what you are eating by starting a small journal or just keep tabs on what you eat with your smart phone dairy starting 3 times a week, do this for a short period, see how you feel & what you can change to bettter suit you getting to your fitness goals.
