Overview
Avoiding and reversing the accumulation of liver fat is the key to preventing insulin intolerance and, thereby, metabolic syndrome, obesity, and metabolic disease. You do that by avoiding and reversing bioreactor dysfunction and dysbiosis, making it a better processor, and staying below certain thresholds for fructose and complex sugars, giving it less to process.
Since one "healthy" yogurt, sports drink, or fruit smoothie can easily have 14 grams of sugar before all those healthy veggies are converted to sugar and a couple of alcoholic drinks, you can see the problem. As far as the liver is concerned, there is little difference between a pint of craft brew, a shot of liquor, a glass of wine, and a glass 1/3 full of sucrose sugar.
Nevertheless, the issue differs from how much you consume in a day. It's how much reaches the hepatic portal, which requires a different approach. For example, the same 14 grams of sugar in a fast-moving liquid smoothie are far more likely to reach the portal than 14 grams buried deep in a slow-moving food bolus.
A bioreactor with no dysfunction or dysbiosis is far more likely to complete the sugar processing before the portal than a dysfunctional bioreactor with severe dysbiosis. You can see over time how, as you move along the spectrum of metabolic syndrome, obesity, and metabolic disease, the condition begins to accelerate and "feed on itself." You must stop feeding the condition and allow the bioreactor and microbiome to heal. Temporary weight-loss diets or even healthy-food diets alone cannot avoid or reverse metabolic syndrome, obesity, and metabolic disease.
