Why Sugar Cravings Strike Two Hours After Meals
It is common for people to want something sweet after a meal.
This can happen when blood sugar rises quickly and then falls.
Foods such as white bread, sugary cereal, sweet drinks and desserts may make this more likely.
Protein and fibre can slow digestion and help you feel full for longer.
Your gut and brain also communicate about hunger and food choices.
Sweet foods can activate a reward response, which may teach the brain to want them again.
Stress and poor sleep can make these cravings stronger.
Low blood sugar after eating can sometimes cause shakiness, sweating, dizziness or sudden hunger.
If cravings are frequent or come with these symptoms, a doctor should be consulted.
Sugar cravings commonly occur one to three hours after eating and may follow a rise and fall in blood sugar.
Meals high in refined carbohydrates, including white bread, sugary cereals, sweetened drinks and desserts, may worsen blood-sugar swings.
Protein and soluble fibre can slow digestion, support fullness and help regulate glucose absorption.
The gut-brain axis, learned reward pathways, stress and poor sleep may all influence sweet-food cravings.
Frequent cravings accompanied by dizziness, shakiness, sweating or rapid weight changes warrant medical advice.
