Calories made simple
Estimate how many calories you need per day and see how meals and snacks add up, with visual portions that make the numbers easy to understand.
It answers questions like 'how many calories should I eat a day', 'how many calories in a banana' and 'how many calories do I need' — your estimated daily need is based on your body weight, and every meal and snack adds to the day's total with visual portions. A simple way to build intuition about calorie intake, portion sizes and energy balance.
