Best Foods to Eat to Get Rid of Belly Fat

Belly fat, the dreaded fat around the abdomen that is so lovingly referred to as a “spare tire” and “muffin top”.  Although belly fat’s nick names may be cute, belly fat is not, and many people struggle throughout their lives with belly fat and will do almost anything to get rid of the excess fat tissue around their midsection.

Dangers of Belly Fat

Even though belly fat may not be visually appealing, it’s effects on your health can be even more concerning.  Think of belly fat as an iceberg, you can see it above the water but most of the dangers lie below the surface.

Excess fat tissue around the midsection has been proven to be a risk factor for:

  • Type 2 Diabetes
  • Insulin Resistance
  • Fatty Liver Disease
  • Increased Heart Disease
  • Cancer
  • Increased Pre-mature Mortality
  • Sleep Apnea

Does Your Waist Size Put You At Risk?

There are many ways to calculate and quantify increased risk of health problems due to your weight including: BMI, body fat percentage, and various ratio calculations.

However, the easiest method is a technique developed by Dr Margaret Ashwell.  Ashwell’s method is to measure you height with a piece of string, fold the string in half, and then measure you waist, if the string still fits around your waist when folded it in half you are not at risk, and if the string does not fit around your waist, you are at risk.  Pretty simple right?

Based on the string method by Margaret Ashwell, the golden rule as it pertains to your waist size is: your waist circumference should be less than half your height.

So if you are worried that the size of your belly may be too big, there is no need to buy any fancy devices to measure your body composition, all you need is a piece of string.

If you want an even more in depth measurement to find out if the size of your belly can put you at risk you can check out the Margaret Ashwell’s Shape Chart here.  You will be able to determine your body shape (ex. apple, pear etc.) based on your height and waist measurement.

Best Foods to Eat to Get Rid of Belly Fat

So now that you have determined if you are at risk due to a large belly, find out the foods that you should eat that will help shrink your belly fat.

1. Low Glycemic Foods

The glycemic index is a way to rate the way foods effect your blood sugar.  A low glycemic index (GI) means that the food does not cause a large spike in your blood sugar, and a high index means that a particular food does cause a large spike in your blood sugar.

It is ideal to keep your blood glucose as level as possible all day.  When your blood sugar spikes too high or too often throughout the day it can cause fatigue and can cause added stress to your body and negatively effect your hormones.  Specifically, the hormone cortisol is most negatively effected when your blood sugar is uncontrolled.  Cortisol is a stress hormone that can predispose you to having added fat around your midsection.

Harvard University has put together a list of 100+ common foods and their respective GI rankings, which you can find here.

The general rule of thumb with the glycemic index is:

  • Foods with a ranking of 55 or less on the glycemic index is good.
  • Foods with a ranking of 56- 69 on the glycemic index is OK.
  • Foods with a ranking of 70 or higher on the glycemic index is bad.

2. Protein

One of the most powerful appetite suppressants around is protein.  Protein is great for suppressing appetite because it

stabilizes blood sugar and it takes longer for your body to digest compared to carbohydrates.  Keeping your appetite suppressed by controlling

your blood sugar is vital because you are less likely to snack on sugary high calorie snacks which are one of the major causes of belly fat.

Also, your body does not as effectively break down protein, compared to carbohydrates or fats, which causes calories to be lost in the digestion process, and therefor your body registers that you ate less calories, which over time can lead to weight loss.  So if you find that you are counting calories and you are still not losing weight on a reduced calorie diet, don’t reduce your calories any further, instead trying increasing your protein consumption and decreasing your consumption of carbohydrates.

The best proteins to consume are meat based because they contain all the essential amino acids, which are not found in plant based foods alone. However there are some non animal based proteins that can suffice if you are a vegan/ vegetarian.Best protein sources

3. Omega 3 Fatty Acids

Omega-3 fatty acids are an incredible source of nutrients and have many health properties, but one of the best things about foods that contain omega 3 is that they can help get rid of belly fat.

Omega 3 is a powerful anti-inflammatory that fights chronic inflammation in the body.  Inflammation has been found to be an underlying risk factor in a plethora of diseases including: obesity, diabetes, insulin resistance, heart diseases, and cancers.  If you increase your intake of foods that contain omega 3 and decrease hidden inflammation in your body you will have an easier time losing belly fat.Best sources of omega 3

The best sources of omega 3, similar to protein, are animal based products.  Animal based omega 3 sources are a slightly different type of omega 3, called EPA and DHA, which are more effective and efficient in our bodies compared to the omega 3 found in non animal sources, called ALA.

    I have not heard of Dr Margaret Ashwell’s method for measuring if your waist size puts you at risk. It is a really simple way to quickly test your risk factor. I will be using this for my patients from now on.

    Our modern diet of convenience is causing all sorts of health problems, and unfortunately most people are totally unaware of the damage they are doing at every single meal. Too many refined carbohydrates and processed foods are stressing our bodies and creating a pro-inflammatory state that is leading to chronic disease.
    The information you are providing here is vital to our quality of life as we age, and an expanding waistlinbe is a tell tale sign that you are going in the wrong direction!

    I believe that nutrition should be covered in more depth in our schools so that kids can teach their parents about it! That might be a bit controversial for some, what is your view?

      Hi Dr Brad,
      I am really happy that you have learned a new technique that will be able to help your patients achieve a healthy lifestyle. I have had the pleasure to meet Dr Ashwell in London, where she is based, and it was remarkable to hear her speak about her research and the string method, which I believe is not utilized enough in the public health arena, especially here in the US.
      I also agree that the modernized diet, with highly processed foods, is causing long lasting damage to the public and will impact future generations. Healthy lifestyle choices, including nutrition, need to be taught from a young age. Once people become older, habits, particularly bad habits are very difficult to change. Children may be able to help their parents learn new healthy lifestyles, but ultimately it will depend on the parent’s willingness to change.
      Thank you so much for your thought provoking comment!
