A food diary helps you see what you eat throughout the day. Recording meals, snacks and drinks gives you a clearer picture than relying on memory alone.
Your entries can help you notice patterns, such as long gaps between meals or frequent snacking. This can help you find small changes that fit your routine and plan your meals. Calotank also shows how much of your daily calorie budget is left.
