If you can, have breakfast. Try eating smaller amounts of high quality, nutritious food more often. Where possible, move away from sugar and towards protein and fibre.
Know yourself – if nerves or scheduling means you can’t eat before a show or a bump in, figure out when to have your main meal. Experiment until you find your rhythm. Do eat when you can.
If eating late at night, try to avoid big servings and high fat meals. Aim for a small meal containing a complex carbohydrate with a quality protein source.
If eating on the run (while walking, driving, talking) try to slow down. Stop and sit, pull over momentarily, or end a phone call or meeting a couple of minutes early. Most people eat a full meal in 7-15 minutes. Can you give yourself that time to eat without rushing? If not, the scheduling may be too tight.
