Fat Loss

The way the low-carb plan was sold to you, the first stretch will be the hard part, with your body tired, hungry and learning to run on a new fuel. Somewhere on the far side of that stretch, a switch will flip, and your body will burn its own fat around the clock rather than sugar. Fat loss will then speed up by itself, because being fat adapted will make you lose more fat with no extra effort. Weeks on, the hard part is behind you and the payoff is late. Each afternoon without a slump, each long gap between meals and each reading on a ketone strip gets logged as progress toward the switch, and every time fat loss drags, you reach for the plan's own explanation, not switched over yet. That explanation carries no date, so it can keep the payoff one step ahead of you for however long you keep eating this way.

Keto Flipped the Fat-Burning Switch Fast and Left Fat Loss Where It Was
