Craig explains why fat loss is about more than simply lowering calories, including the role of fuel partitioning, protein, dietary fat, carbohydrate intake, and the Randle cycle.

They also explore why traditional high-fat keto or carnivore approaches can initially work well yet eventually lead to plateaus—or even weight gain—for some people, and why shifting toward a higher-protein, lower-energy approach may help.

A major focus is protein-sparing modified fasting (PSMF): how Craig and Maria structure PSMF days, who may benefit most, how often they recommend using them, and why strategic maintenance days may help support long-term results.
