Find alternatives and wean yourself off the level of sweetness of a food. So if you are used to 1 teaspoon of sugar in your tea, have a half teaspoon. If you drink juice neat, try with half water instead.
Try switching to sugars that taste sweet, but don’t affect blood sugar that much such as xylitol, agave syrup and stevia.
If you are used to eating sweets find something with less sugar. Look for bars that don’t use dates, raisins or sugar in their top three ingredients. Raspberry nut bars are quite good for GL. I sometimes munch dark chocolate with some peanuts. Even better would be to snack on berries, cherries or plums or have a slice of low GL bread or toast, with a nut butter and a tiny spread of sugar-free jam.
Drink water and have a low GL snack. Whenever you find yourself dreaming of something sweet first have a glass of water, then have a protein/carb snack as I specify in all my low GL books.
When you crave something sweet what are you really craving or missing? You may find you need to sleep, or are upset about something, or even need a cuddle. If you are upset about something how can you attain peace? An option is to go for a walk outside then have a real meal first. You may find your craving subsides.
These are my favourite six steps to lessen cravings. Practice them for a month and you may find you are out of the grips of the evil white powder!
