The Carbohydrate Problem

Almost everything I've read shows the problem of body fat to be connected to carbohydrate.  Researchers slice and dice things, but in the end, it is all related to carbohydrates.  The sub-issues of glycemic index, glycemic load, total grams of carb, etc., all play a role (and are interrelated).  But if you have a body fat problem, you have a carb problem.  Maybe an exception would be if someone is high-dosing tons of bad fat (perhaps via fast food), but this would seem to be rare.

Individual experimentation is probably key for solving the carb problem.  Carb tolerance also changes over time due to aging, and is affected by exercise and conditioning levels.  Sugar and refined carbs benefit no one, and only the young and athletic seem to be able to abuse them and get away with it (in terms of low body fat).  But bad carbs will catch up with anyone in the end, and it's best to replace them with healthy fruits and vegetables.
