Answer: Having a small salad before meals.
Explanation: It's the only option that makes sense.
- Using a large plate that holds more food leads to eating larger portions, So this is incorrect
- Eating foods with lots of carbohydrates first equals more calories so this also wrong
- Drinking high-calorie drinks with meals so that you eat less This is also not good since it's still added calories, generally if you're replacing volume of food with liquid it's better to drink a glass of water before a meal.
