10 Practical Hacks to Eating a Low Glycaemic Index Diet

Eating a low glycemic index diet to maintain healthy blood sugars, reverse prediabetes or manage type 2 diabetes is not about eliminating food groups or following strict diet plans. It is about choosing high-quality carbohydrates and pairing them with the right foods in the correct portions.

All carbohydrate-containing foods affect blood sugar. 

The glycaemic index is a way of assessing how carbohydrates in foods affect blood sugar levels.  It essentially ranks food on a scale of 0 (lowest) to 100 (highest) based on how quickly they raise blood sugar.  Foods that raise blood sugar slowly have a low number/rating, while those that affect it quickly have a higher rating/number.  

The way to eat a low glycaemic index diet is to eat foods that raise blood sugar slowly or moderately more often than foods that increase it quickly.  When you plan out your meals and snacks this way, you eat a low glycaemic index diet. 

Unlike traditional diets, there are no meal plans or foods to avoid.  It is simply just a way of eating that lowers heart disease risk, helps you achieve blood sugar balance, and reach and maintain healthy body fat levels.  

Here are 10 practical hacks to help you eat a low glycaemic index diet. 

1 | Eat More Vegetables

Of all carbohydrate-containing foods, vegetables have the lowest glycaemic load.  Vegetables are rich in vitamins and minerals, including magnesium, iron, vitamin A, and calcium.  Vegetables are also good sources of dietary fibre, a non-essential, but crucial carbohydrate that helps with blood sugar regulation. 

The best thing about vegetables is that you can eat as much of them as you wish.  And with so many colours and textures, you can hardly get bored.  The most important thing is to cook them using healthy techniques (steaming, stir-frying, or grilling) with fruit oils and less saturated fat.  Add vegetables to main meals, snack on them, add them to smoothies or stews.  

2 | Swap meat with legumes a few times a week

Legumes include beans such as red kidney beans, chickpeas, green peas, and all varieties of lentils.  Legumes are fantastic sources of protein and fibre and are naturally low-glycaemic. 

You can eat legumes in place of meat a few times a week or add them to salads, sandwiches, soups, and stews. 

3 | Replace added sugar with fruit at breakfast cereals

Whether it’s oatmeal, millet, cornmeal or pre-packaged cereal, many people tend to add sugar to breakfast cereals.  The concern is that some of these cereals, especially pre-packaged cereals, have added sugar, and with the processing, they raise blood sugar levels very quickly.  Adding more sugar, whether white, brown, maple syrup, honey or agave, only increases the glycaemic index of the diet further. 

Choose fruits, including apples, apricots, strawberries, bananas, blueberries, or mangoes. 

4 | Eat whole food snacks

When snacks are mentioned, most people immediately think of pre-packaged products such as granola bars, biscuits, crisps, or energy balls.  While they’re not all created equal, such snacks are often high in saturated fat, sodium and added sugars, and most importantly, they’re nutrient-poor. 

Eating whole food snacks presents an opportunity to get the nutrients you may miss at your main meals and also maintain balanced blood sugars.  Whole food snacks can include sandwiches with smoked salmon, chicken or tofu, legumes including steamed edamame or roasted chickpeas or a boiled egg with vegetables.  You can also have salads or even leftovers from lunch. 

5 | Choose high-quality bread

Bread doesn’t have to be off the menu just because you’ve decided to eat a low glycaemic index diet.  The key is to choose breads made with wholegrain flour in adequate portions.

Some of the best low glycaemic options include rye bread, soya and linseed bread, sourdough, or Ezekiel bread.  Eat these breads with a portion and healthy fat to keep the glycaemic index low. 

6 | Use less sugar in baking

Sticking to the recipe in baking is crucial, or else the result can be disastrous.  This is true for many of the ingredients in a recipe, but not so much for sugar.  You can use up to a third of the sugar a recipe calls for and still have a delicious product. 

The recipe you make may not be low glycaemic, but this is okay.  Eat foods like this less frequently and crowd your diet with whole, natural foods and your overall diet will still be low glycaemic

7 | Cook pasta al dente

Italians never cook soft pasta; they always make it al dente, meaning firm to the bite.  Cooking pasta until it’s very soft makes it high glycaemic, but al dente, it is low-medium glycaemic. 

It might take a little while to get used to the firmer texture, but once you do, you’ll find it difficult to eat soft pasta. 

8 | Choose rice wisely

Rice is another food many people think they need to skip when eating a low glycaemic diet, but this couldn’t be farther from the truth.  Rice is a staple in many African, Chinese, and Indian cuisines, and it would be extremely challenging, if not impossible, to eliminate it from your diet if you’re a native of these populations. 

Fortunately, rice is not created equal.  Some raise blood sugar more significantly than others, primarily due to the proportion of starches they contain.  For the best glycaemic control, choose basmati or black rice more often than o.  Pay attention to portion sizes and pair them with high-quality proteins and fats.  

9 | Pair carbohydrates with proteins and fat

You’ve probably seen this mentioned a few times in this article.  Pairing carbohydrates with high-quality proteins and fats is a fantastic way to lower the glycaemic index of your meal. 

Proteins and fats have minimal effects on blood sugar, and they digest slowly.  Pairing them with low glycaemic index carbohydrates further slows digestion, lowering the glycaemic index of your meal.  You can get away with eating a (correctly portioned) high-glycaemic carbohydrate if you pair it with proteins and fats. 

10| Practice portion control

Low glycaemic foods only lead to a low glycaemic diet if your portion sizes are adequate.  Eating large quantities of a low glycaemic food still causes blood sugar spikes. 

The right portion size for you depends on age, weight, activity levels, and goals.  Work with a registered nutritionist or dietitian, or use this personalised portion planner to work out the right portions for you.

And there you have it, 10 practical hacks to help you eat a low glycaemic diet. 

Remember that eating a low glycaemic diet is not about meal plans or eliminating tasty foods from your diet. It’s all about swapping refined carbohydrates for whole options, pairing them with highly quality fats and proteins, and most importantly, practising portion control. 

Don’t make all these changes at once if it will cause overwhelm. Pick one, master it then move to the next. And if you still can’t crack it on your own, a registered nutritionist or dietitian will be delighted to help.
