Sweets represent one of the biggest challenges for anyone trying to lose weight, but not because sugar is inherently harmful. The real problem lies in caloric density - a very small amount of food packs many calories with relatively few beneficial nutrients and a weak feeling of fullness.
Take, for example, three crepes with Nutella. Depending on the size of the crepes and the amount of spread, such a dessert can contain between 600 and 800 calories, and with a more generous spread, toppings like sugar or whipped cream, the number climbs to as high as 1000 calories.
How Much Running Does One Dessert Cancel Out?
To understand the scale, it's useful to look at calorie expenditure during physical activity. A person weighing approximately 90 kilograms burns roughly 90 calories per kilometer while running. Very roughly, to burn 700 calories, you would need to run a distance of seven to eight kilometers. If the dessert reaches 1000 calories, we're talking about needing to run ten or more kilometers, depending on body weight, speed, and terrain.
What makes this calculation particularly unforgiving is the time disparity. Three crepes can disappear in just ten minutes, while the running that would energetically cancel out that dessert can take nearly an hour.
Why Don't Sweets Satisfy?
Sweets are also problematic due to their composition. They mostly contain a combination of sugar and fat, making them extremely calorie-dense, yet they often don't satisfy nearly as much as a proper meal of the same energy value. For 700 calories, you can eat a substantial amount of chicken, vegetables, and potatoes or another whole meal that will keep you full for hours.
Consuming excessive amounts of added sugar is also linked to an increased risk of weight gain, tooth decay, metabolic disorders, and other health issues. Of course, one crepe won't ruin your health, nor is it forbidden to ever eat something sweet, but for someone looking to lose ten or twenty kilograms, the math is unforgiving.
Chocolate, cookies, cakes, croissants, and crepes can pack in calories in just a few bites that would later require walking or running for kilometers to burn off. That's precisely why cutting out sweets is often one of the simplest and key changes that can seriously accelerate the weight loss process.
