Richard Nikoley makes a point I’ve made before … if you need to adjust to reducing carbs, you also need to adjust to increasing them. LCers should not be taking their blood sugars the first time they eat their first big serving of carbs IMO!
Anyways, in the thread I linked to, Skyler Tanner mentioned a comment he made elsewhere which I think is key (emphasis mine):
Body composition is a function of calories and training; hormone drives are influenced by the quality of the diet and the propensity of neolithic agents of disease; reducing carbohydrate levels (lower but not “low-carb”) increases lipolysis by way of insulin reduction, thus energy needs are being increasingly met by lipid fuel sources (fatty acid and ketones); foods that have low reward help move us toward an appropriate body composition more easily than high reward foods because you’ll eat less to satiety.
These all matter and everyone who has a pet theory is arguing like it exists in a vacuum. It’s like arguing with leg of the table is most important: depending on circumstances one may matter more but isn’t the only factor at play, not by a long shot.
