I am also an obese bitcoiner, struggling daily with a sugar addiction. Will I ever not be obese? Time will tell. Will I ever not be addictes to sugar? I doubt it. 

I will say that oils were not that hard to give up. I assume that I still consume some when dining out, but not enough to matter. I've definitely experienced benefits directly related to not having oils in my diet, including a much higher resistance to sunburn.

I was reflecting today on how many ways people poison themselves, gladly, in the name of health. I don't care if someone wants to eat a plant. Sure, they are ingesting whatever plant toxins it has, but hopefully in a very low amount compared to what may cause harm. I think processed "foods" are possibly the worst offenders, along with "supplements". Saw a jar or powder claiming "Fiber - with real sugar!". To me, that reads "cardboard, with real cocaine!". And to be fair, cocaine might be preferable, and do less damage!  People consume this shit because the govt and pharma tells them so, and poison themselves as a result.

So go ahead, eat some berries. Maybe some lettuce or a cucumber or whatever. I choose not to, but you do you. If you're not a sugar addict, maybe have some honey once in a while. But don't eat shit out of boxes, plastic bottles, etc. Your food should be recognizable as its ingredients. Just my thoughts as an obese bitcoiner. 

 replace your processed sugar foods with foods sweetened with honey, maple syrup, fruit juice, those sweets are healthy. Refined sugar and high fructose corn syrup will make you unhealthy.
