Reducing your calorie intake can be an effective way to lose weight.
However, not all foods are equal when it comes to nutritional value. Some foods are low in calories, but also low in nutrients.
When limiting your calorie intake, it's important to choose nutrient-dense foods, which contain a lot of nutrients for the number of calories they provide.
What's more, a diet full of whole, nutrient-dense foods may help you feel more satisfied while cutting calories (1).

Because they are high in protein, meat and poultry are good foods to eat when you're trying to cut calories.
Meats that are lowest in calories are the ones that are very lean. Fat is calorie-dense, so fattier cuts of meat have a higher calorie count.
