1. Drink water before meals
A glass of water 15-20 minutes before a meal can take the edge off hunger and make it easier to eat a reasonable portion instead of overeating. Thirst is also commonly mistaken for hunger, so staying ahead of it with regular water intake through the day can reduce unnecessary snacking. It is a small habit, but it costs nothing and is easy to build into your existing routine — keep a bottle at your desk or dining table as a simple reminder.
