Foods rich in monounsaturated fats

Research has linked monounsaturated fats with a decrease in belly fat. The reason for this may that monounsaturated fats fight inflammation. By helping to decrease inflammation in your body, these fats can help decrease the physical stress that can pack on pounds.


  • Olive oil
  • Almonds
  • Olives
  • Avocado
  • Peanut Butter
  • Olive oil based salad dressing
  • Hummus


Foods rich in whole grains

Whole grains help promote belly fat loss by helping to control your appetite. Since whole grain foods get digested slower than refined versions (such as white bread, cakes and cookies), they keep you feeling full for longer. In addition, thanks to the slowed digestion, insulin response is limited and you might have fewer cravings.


  • Steel cut oats
  • Bran cereal
  • Whole grain waffles
  • Whole wheat pasta
  • Brown rice
  • Quinoa
  • Beans
  • Air popped popcorn
  • Whole grain bread


Lean proteins

Protein plays an important role in weight loss and weight maintenance. Protein helps you build (and keep!) lean muscle tissue, increase the number of calories you burn every day, boost your metabolism, and promote weight loss. And it helps to fight off hunger! As you can see, without adequate protein, weight loss may be more difficult. Just make sure to choose lean protein options, such as the following.


  • Beef:
    • Ribeye
    • Top Sirloin
    • London Broil
    • Beef Stew Meat
    • Flank steak
  • Pork:
    • Boneless Pork Loin
    • Sirloin Tip Roast
  • Poultry:
    • Whole chicken
    • Cornish hens
    • Chicken breast
    • Turkey breast
    • Ground chicken breast
    • Ground turkey breast
    • Eggs
    • Egg whites



  • Farmed and Wild Salmon
  • Halibut
  • Cod
  • Trout
  • Shrimp


  • Kirkland Wild Alaskan Sockeye Salmon
  • Kirkland Wild Alaskan Pacific Cod
  • Kirkland Wild Alaskan Mahi-Mahi
  • Kirkland Tail-On Raw Frozen Shrimp
  • Kirkland Cooked, Deveined Frozen Shrimp
  • Bear and Wolf Wild-Caught Pink Alaskan Salmon


Dairy products contain whey, a protein that helps promote the formation of lean body mass (which helps you burn more calories). Since dairy is high in protein, it keeps you feeling full for longer, which helps you reduce your portions, promoting weight loss. In addition, a study published in Obesity Research showed that obese individuals who ate a diet rich in dairy lost a lot more body fat and weight than people eating the same number of calories but following a low-dairy diet. And, the best part was that most of the fat lost came from the midsection. So increasing your intake of dairy may help you flatten your belly faster than just cutting calories alone.


  • Low fat cottage cheese
  • Greek yogurt
  • Low fat milk


  • Daisy Brand Cottage Cheese
  • Fage Plain 0% Fat Greek Yogurt

Foods that cool inflammation


One of the main benefits of vegetables when you’re trying to lose weight is that they provide you with a great amount of volume and feeling of fullness with very few calories. In addition, vegetables are packed full of fiber and antioxidants. These antioxidants help to cool inflammation in the body which, when elevated, can cause your body to store fat.


  • Artichoke
  • Asparagus
  • Bell peppers
  • Broccoli
  • Green beans
  • Hot peppers
  • Kale
  • Mushrooms
  • Spinach
  • Onions


  • Kirkland Stir-Fry Vegetable Blend
  • Kirkland Normandy-Style Vegetable Blend
  • Byebee Organic Spinach
  • Byebee Organic Frozen Green Beans


Similar to vegetables, fruits are packed full of water and fiber, which makes them filling with few calories. In addition, their high antioxidant content can fight inflammation. One added benefit is that fruit gives you a “sweet satisfaction,” which can help reduce cravings for less friendly-to-your-belly sweets, such as candy. Studies have even shown that people who eat a large amount of fruit lose more weight than people who eat a large amount of vegetables but not as much fruit! So that reason alone may be a great incentive to start eating more.


  • Blueberries
  • Blackberries
  • Strawberries
  • Raspberries
  • Grapefruit
  • Pomegranate
  • Apples
  • Peaches
  • Plums
  • Oranges


  • Kirkland Nature’s Three Berries
  • Kirkland Frozen Strawberries
  • Pure Nature Frozen Organic blackberries

Stress fighting foods

When your stress levels are elevated, your body turns into a fat storing machine. In fact, during times of high stress, your body packs on fat right in your midsection, leading to an enlarged waistline. One great way to cut down on the effects of stress in the body is to increase your intake of omega-3 fats. Since an increased intake of dietary omega-3s keeps your stress hormones steady, it can also prevent the effects of these hormones. Having more omega-3s in your meal plan will help cut stress hormones, and therefore, cut down on the amount of belly fat they can store. Some great sources include:

  • Salmon
  • Tuna
  • Walnuts
  • Chia seeds
  • Flax seeds
