Four handles drive most cravings, and they stack. The post-meal dip: refined carbs spike blood sugar, then drop it below baseline, and the brain reads that as fuel running low; the biggest dips track with a fifth more hunger and 300 extra calories a day ¹. Short sleep: a bad night raises the hunger hormone and drops the full one ², adding about 385 calories the next day, mostly sweet and starchy ³. Stress: cortisol makes sugar and fat feel more rewarding, and eating them dulls stress, so the loop feeds itself ⁴. Low protein: appetite stays high until the body gets the protein it wants, and you graze on sugar and starch meanwhile ⁵. Which handle you're in tells you the move.

Every lever is modest alone; they work because they stack. Slower carbs plus 25 to 30 grams of protein per meal blunt the next dip ^{1 6}. In the moment, pausing to notice the craving as a passing thought cut chocolate eaten by about a fifth; accepting the urge beats fighting it, which only amplifies it ^{7 8}. The white-knuckle ban does the reverse: rigid no-sugar rules produce more cravings, not fewer ⁹.

Handle the craving now; fix the setup so the next one is smaller.

Inside a week of decent sleep and protein-led meals, the 3 pm pull shrinks and you walk past the snack drawer without noticing. Two to four weeks in, sweetness recalibrates and birthday cake tastes too sweet. Inside a year weight usually drifts gently down without a diet, the size seen when trials change only sugar intake ¹¹. Over fifteen years the stakes climb: the top fifth of added-sugar eaters die of heart disease at roughly 2.75 times the rate of the lowest ¹².
