Your last comment is why keto works quite well. It removes the insulin spikes and with it the energy troughs. The other reason I'm convinced keto works great is that it helps rebalance your microbiome. This is all from personal experience using Viome to measure effects however I wasnt using it for weight loss, that was just an (undesired for me) side effect. It should also be noted that a significant amount of weight loss from keto is actually water loss.
