No science from me, but... I am definitely addicted to sugar, and any natural sweetener including honey. Whether it be boiled hard candy or just homemade jello with added sugar, or even homemade jello made with just 100% grape juice. I would feel the need to binge on it. I just can't have it in the house or it starts me on a cycle of eating between meals and not being able to stop. I have had leaky gut, but think I am doing much better now, but I do have to stay away from the sugar. Cashews are the same for me, unfortunately.
I think we each just have to know our own kryptonite.
Started Primal June 2012 at 148.5lbs, and 5' 1", reached goal weight in 5 months.
Lowest weight 93lbs - too thin. Now stable at around 100lbs much better weight for me at my age.
Primal, minus eggs, dairy and a myriad of other allergens.
