Lots of studies have shown that people who actually keep track of what they eat on paper, in an app, or in some other record, have better success at losing weight.
Tracking will make sure that you do not overeat and that you do not under eat.
And you will learn about where your calories come from. You will learn about macronutrients (protein, carbs and fats) and how they work in your body. It’s also a good idea to add accountability where ever you can . Put a menu up on the fridge of the food you are going to eat. It might sound silly, but these little things will help you.
NOTE: Starving yourself will slow your metabolism down and the body will do everything it can to hold on to fat.
