Here we have one of the most tempting and richest sweets in Europe! The Liège waffle is different from the light Brussels waffle: it is made from a dense, butter-rich brioche dough studded with large sugar nibs called "pearl sugar" that melt and caramelise on the hot iron into a glassy, crunchy crust. One waffle (100 g) has about 420 kcal, as much as a full meal, and more than 50 g of available carbohydrate, much of it sugar. Our team estimates its glycemic index at about 75 (high), and its glycemic load is very high, so it raises blood sugar quickly. The smart trick: do not deny yourself one on a visit to Belgium, but share it with someone, eat it after a meal with protein and salad rather than on an empty stomach, and walk for 15 to 20 minutes afterwards to help your muscles use up the glucose.

Can people with diabetes eat a Liège waffle?
With great care: half a waffle after a main meal, followed by a walk, is possible on special occasions, but eating it regularly raises your HbA1c.
Why is a Liège waffle so much heavier than a Brussels waffle?
Because a Brussels waffle is made from a light, runny batter with whipped egg white, so it turns out airy and crisp, while a Liège waffle is a dense yeast dough rich in butter and pearl sugar.
Is it a good pre-workout meal?
For athletes doing long endurance training it can be a quick source of energy to fill glycogen stores; for non-athletes it is a lot of calories that easily exceed needs, and a simpler snack is a better choice.
