Why do we crave sugar?
According to Reema Pillai, registered dietitian at Dietitian Fit & Co, sugar cravings are normal and can be both biological and psychological.
"It comes from when there was a time when food was scarce, and we as humans had to eat a lot of high calorie foods for our survival," she explains.
Sugary foods also affect the brain's reward system, triggering the release of feel good chemicals such as endorphins and serotonin. These boost our estado de ánimo, leaving us wanting to go back for more. In other words, eating sugar kickstarts a chemical reaction that can create a cycle of addiction.
Studies have also found estrés y lack of sleep may be linked to sugar cravings. When you eat sugar, hormones are released to reduce the feelings of estrés. In turn, this increases your desire for comfort foods, creating a cycle of emotional eating habits.
If you don't get enough sleep you'll tend to crave foods that are sweet, salty, and starchy. This may be because these foods make you feel good. Poor sleep has also been linked to the appetite-regulating hormone ghrelin - which makes us feel hungry.

How to fight sugar cravings
Volver al contenidoCraving sugar is usual and you shouldn't feel guilty about having chocolate now and again. However, eating too much can lead to aumento de peso, diabetes tipo 2, tooth decay, and can increase your likelihood of several serious medical conditions. A diet rich in sugary foods and drinks can lead to la obesidad, which raises your chance of cáncer y enfermedades del corazón.
Cutting down on your sugar intake isn't easy, but there are steps you can take to make the process easier.
Think about why you’re craving sugar
It's important to stop and think about why you're craving sugar.
Pillai asks: "Are you physically hungry, or is there something else going on here? Are you looking to satisfy an emotion you're feeling, and perhaps using sugar to do so? Looking to meet that emotion in other ways is important."
For example, if you notice you feel very stressed and are craving sugar, could you try other herramienta de manejo del estrés techniques such as ejercicio, meditación, or journaling?
Distráete
Try doing something to take your mind off the craving and allow it to pass.
Pillai says: "Remember, it is OK to have sugar, but it’s important to not let it be the main go-to when you need to meet your emotions in other ways that can help in the long term."
Ejercicio releases endorphins - feel-good hormones - that can boost your mood and reduce stress.
Try food swaps
It's important not to completely restrict yourself when it comes to sweet foods, as you’ll end up craving it even more. Sometimes, it can help to swap sweets or chocolate for healthier alternatives such as fruit. However, be mindful that some seemingly healthy foods such as yoghurts can contain sugar. Pillai also suggests eating a small amount of what you fancy.
She advises: "Take a small portion in a bowl and be sure to eat this slowly and mindfully, allowing you to fully concentrate on the taste, flavours and sensations. This can help you feel satisfied with the smaller amount and stop the cravings."
Focus on your diet
Eating a healthy and balanced dieta overall can help reduce sugar cravings.
Pillai says you should make sure you are having filling meals throughout the day with enough fuentes de proteína, wholegrains and healthy fats, and make sure you’re not waiting too long between meals.
"This will help to prevent your energy and azúcar en sangre levels from dipping," she explains. "When this happens, it’s very easy to go for something high in sugar to make us feel better."
