7 healthy eating tips to avoid the holiday weight gain: Plan your plate before filling it and save space for the items you want most. Don’t underestimate the calories contained in holiday drinks and alcoholic beverages. Never drink on an empty stomach again by taking a tablespoon of extra virgin olive oil before you leave home. Don’t show up famished as it increases the chances for overeating. Slow down and practice mindful eating. Pick three non-food goals that have nothing to do with eating like getting to know a certain person better. If you do feel like you overdid it, don’t be too hard on yourself. Studies have shown that the average American gains less than a pound during the holidays.
