Eating out regularly can lead to weight gain over time due to large portion sizes and high calorie, sodium and carb options on menus. However, there are strategies for making healthier choices when dining out, such as using online nutrition tools to plan ahead, asking for substitutions, sharing entrees, and focusing on nutrient-dense options like vegetables, whole grains and lean proteins. The key is being prepared and making choices mindfully to stay within calorie, carb and sodium goals.
