i want to eat healthier. what kind of food in my diet should i cut out? Everyday I have a yogurt, burger, pizza, salad, and coffee.

It depends what your goals are for dieting. However, burgers and pizzas are generally not healthy due to a lot of trans fat and unhealthy carbs. Burgers and pizzas are also often fast food which means they are made with processed ingredients. Yogurt, salad, and coffee do not need to be cut out but in excess they can be unhealthy too. So, always eat or drink in moderation,
