I use a sugar substitute called erythritol which has no carbs, taste just like sugar and does not illicite an insulin response in the body.
But if you choose not to go down the Keto route like I did then it's 6 teaspoons per day for women and 9 teaspoons a day for men.
I hope you have fun experimenting with discovering your ideal sugar intake… every body is different, and only you know your body best!
But I can tell from the sluggishness and mental fog if the sugar is also in excess
Not so bad is natural sugars but really these should be minimised too. Veg wins over fruit Heath wise by a mile for this reason.
Many Americans are eating sugars that don’t have GLUCOSE in them.
I do know that breast milk has the highest level of sugar than any other mammal’s milk.
