21-Day Paleo Meal Plan
Three weeks is long enough for the shopping, cooking and cleaning to become habit rather than effort. That habit, not the food itself, is what makes the change stick.
Estimated 1651 kcal and 109 g protein per person per day. Figures are rough planning estimates, not measured values.

Week by week
Week one is the hardest: your kitchen is not stocked and your habits are elsewhere. Week two the shopping gets faster. By week three you are improvising rather than reading a plan.
Plan for the interruptions
There will be a work dinner, a late night and a day you cannot face cooking. Keep two emergency meals in the freezer and a no-cook fallback in the cupboard so an interruption stays a single meal.
Frequently asked questions
- Is 21 days enough to form a habit?
- The 21-day figure is folklore rather than science, but three weeks is a reasonable block to evaluate whether an eating pattern fits your life.
- What if I break the plan on day 12?
- You resume at the next meal. A three-week plan with one deviation is still a three-week plan.
