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.

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).

Here are 42 foods that are low in calories—and most of them are highly nutritious.

1–4: Meat and Poultry

Because they are high in protein, meat and poultry are good foods to eat when you're trying to cut calories.

Protein helps you feel full for longer and may help you eat fewer calories throughout the day (2, 3).

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.

1. Eye of Round Steak

There's no reason you can't still enjoy a steak while cutting calories. Beef is nutritious and it's a good source of vitamin B12 and iron (4).

Iron is an essential nutrient that helps transport oxygen throughout your body, while vitamin B12 is necessary to form red blood cells (5).

However, note that eye of round is a very lean cut of beef. Be sure not to overcook it or it will be tough and dry.

Calories: 138 calories per 3-ounce serving or 168 calories per 100 grams.

2. Boneless, Skinless Chicken Breast

Chicken is a very versatile meat that is also an excellent source of protein (6).

You can keep the calorie content low by trimming all skin and visible fat.

Calories: 92 calories per 3-ounce serving or 110 calories per 100 grams.

3. Turkey Breast

Turkey breast is high in protein, vitamin B6 and niacin. B vitamins help your body break down the food you eat and metabolize it into energy (7).

Calories: 93 calories per 3-ounce serving or 111 calories per 100 grams.

4. Pork Tenderloin

The tenderloin is one of the leanest cuts of pork, making it a great low-calorie option.

Pork is rich in several B vitamins and it's also an excellent source of high-quality protein (8).

Calories: 122 calories per 3-ounce serving or 143 calories per 100 grams.

5–8: Fish and Seafood

Most fish and seafood are highly nutritious and they are excellent choices when you are restricting calories.

Like meat, fish and seafood are high in protein. They also provide important nutrients like vitamin B12, iodine and omega-3 fatty acids (9).

Omega-3 fatty acids have numerous benefits for your health, including reducing inflammation and improving heart health (10).

5. Cod

Cod is a lean, white fish that is high in protein but low in calories.

It's also high in vitamin B12, iodine and selenium and it contains a decent amount of omega-3 fatty acids. Iodine is important for proper brain and thyroid function, but many people do not get enough of this nutrient (11, 12).

Calories: 70 calories per 3-ounce serving or 82 calories per 100 grams.

6. Salmon

Salmon is a fatty fish that is loaded with heart-healthy omega-3s. It's also high in vitamin B12 and is one of the few foods that naturally contains vitamin D (13).

This is important, as vitamin D deficiency is a common problem around the world.

Vitamin D deficiency is associated with all kinds of health problems, such as osteoporosis, increased cancer risk, autoimmune diseases and high blood pressure (14, 15).

Calories: 99 calories in a 3-ounce serving or 116 calories per 100 grams.

Starchy vegetables like potatoes and winter squashes are higher in calories but still very nutritious.

9. Chinese Cabbage

Chinese cabbage, which includes napa cabbage and bok choy, ranks at the top of the list when it comes to nutrient density. This cabbage is high in vitamins C and K and contains a decent amount of folate (20).
