Keep a Food Journal
It's important to know how many calories you should be eating each day so you can figure out how many you need to stick to in order to lose weight. Keeping a food journal or using an app like MyFitnessPal can help you count calories.
Just remember to tally every single thing you eat for accuracy — taking photos of what you eat can help you remember. It'll not only allow you to track your calories and your macros, but you'll also be able to see if you're eating healthy most of the time.
