Inhaling your food too quickly will make you consume way more calories than you need, and will leave you feeling unsatisfied. Leslie Langevin, MS, RD, CD, of Whole Health Nutrition suggests taking a 10-minute break halfway through your meal to assess whether you should continue eating more or be done. If you find that you're full, don't push the plate away and keep talking with your lunch date or go back to working on your computer. If the food is there, you'll feel too tempted to start picking at it. Wrap it up and put it in the fridge for later or share it with someone else.
