" Ultimately and obviously, the question of how much is too much becomes a personal decision, just as we all decide as adults what level of alcohol, caffeine, or cigarettes we’ll ingest. I’ve argued here that enough evidence exists for us to consider sugar very likely to be a toxic substance, and to make an informed decision about how best to balance the likely risks with the benefits. To know what those benefits are, though, it helps to see how life feels without sugar. Former cigarette smokers (of which I am one) will tell you that it was impossible for them to grasp intellectually or emotionally what life would be like without cigarettes until they quit; that through weeks or months or even years, it was a constant struggle. Then, one day, they reached a point at which they couldn’t imagine smoking a cigarette and couldn’t imagine why they had ever smoked, let alone found it desirable. A similar experience is likely to be true of sugar—but until we try to live without it, until we try to sustain that effort for more than days, or just a few weeks, we’ll never know. "
