Map breakfast, lunch, dinner, and snacks around your chosen adjustment. If testing higher-protein breakfasts, aim for approximately thirty grams using eggs, Greek yogurt, tofu scrambles, or overnight oats fortified with protein powder. Add colorful produce for micronutrients and fiber, and include satisfying fats for satiety. Keep portions predictable for seven days to reduce variability. Your template should feel supportive, not restrictive—flexible enough for real life, but consistent enough to reveal meaningful cause-and-effect patterns.
Create a short, deliberate list: cornerstone proteins, grains or starches, produce, hydration aids, and your variable-specific items. Shop once, prep twice—front-load chopping, roasting, and batch cooking; midweek, replenish fresh elements like greens or berries. Portion meals into containers labeled by day and mealtime to curb decision fatigue. Store easy fallback options like canned fish, precooked legumes, or frozen vegetables to protect your plan when schedules change. Make success obvious and friction small.
