Always eat breakfast...within 2 hours of waking you should have something to eat and then every 3 to 4 hours after that...this will keep your blood sugar levels from spiking and crashing throughout the day. It will also keep your metabolic fire burning all day long. Speaking of metabolism...weight training and building lean muscle mass with increase your resting metabolic rate...that means that you will burn more calories throughout the day, even when you are at rest!
The saying goes...eat like a King at breakfast (big meal), like a Prince for lunch and like a Pauper for dinner..keep your evening meal smaller and eat your complex carbs early in the day (breakfast or lunch) because you will be burning those calories throughout the day and that is when you need the most energy.
Try to avoid eating after 8pm or at least 3 hours before you go to sleep.
If you are looking to lose weight, doing 20 minutes of moderate cardio (just break a light sweat) first thing in the morning on an empty stomach may be just the thing you need to lose those stubborn few pounds.  Your body will use your fat stores as you have been fasting overnight and there are no carbohydrates to fuel your body circulating in your bloodstream. Try this every day for at least 2 weeks to get the results you want.  This cardio is in addition to your regular exercise routine.
