Sweet tooth

Fruit

Another vote for fruit: Making it a point to eat 3 servings of fruit daily for a while gradually reduced my cravings for more calorie-dense sweets like candy and baked goods. (I'm not saying I never eat those, but I'm not struggling to resist them.) This doesn't work for everyone, but I've seen other people here say similar, so it may be worth a try if you can get fruit . . . pretty much any kind of fruit.

Sugary treats are pretty much lab produced food that humans were never intended to consume. If you stick to fresh fruit your body with thank you for fueling it with foods, you were born to consume.

Sub out the sugary, over-processed candy & treats with fruit, esp high sugar fruit like bananas to start with. Over time, your taste buds will adjust to the fruit as they are replaced approximately every two weeks so that the candy stuff will taste too sweet to eat or much of it anyway in my experience. It tastes like eating a spoonful of sugar straight out of the sugar bag to me, which I've done with severe sugar cravings in the past.

Than as the sugar cravings start to die down, replace some of the high sugar fruit with low-sugar fruits to achieve a balance....and eventually, the high sugar fruit also tastes really sweet in comparison, but at least you'll also be eating fiber and getting nutrients you don't get from the candy stuff by eating the fruit instead.

To help deal with the mental cravings I suggest working on your mindset and telling yourself something like.....I am choosing to eat healthier right now to improve my nutrition. In the future, I can have the candy, if I truly want it, as a treat (I suggest as an occasional treat, not a daily treat. I've done that too and it just made the sugar cravings come back/worse for me using it as a daily treat.) Or choose whatever affirmation you want to use to reframe the cravings.

Also, are you craving something specific like chocolate candy? You might want to look into increasing your magnesium level if so. I googled vitamin deficiency and whatever I was/am craving, in this case chocolate, and learned that craving chocolate could be because you're magnesium deficient and I increased my magnesium intake, and it took a few days/week or so and the cravings died down a lot so I really think there's something to that. You can do that for whatever you're craving.
