No, it doesn’t matter to me because the "several other theories" mentioned work best for me, they are combination theories:
Comparing Theories: Carb-Insulin Model and Protein Leverage Hypothesis in Obesity

Your Personal Fat Threshold & High Insulin Levels

These theories are not as simplistic as the CIM, but then our metabolisms are more complicated than "a unifocal reduce carbs" approach. As Calianna wrote, Find the carb level that works best for you, but increasing fiber and lowering fat often has be part of the equation to reach an ideal weight longer term. Adding super high fat is adding super high calories. As Dr Atkins and Westman wrote…calories matter.
