Meal Prep for Professionals: The 90-Minute Sunday System
Meal prep isn't about becoming a domestic god. It's about eliminating the daily decision of what to eat so that your cognitive bandwidth goes towards your work and your nutrition goes towards your goals.
Why meal prep is a professional superpower
Decision fatigue is real. Every time you choose what to eat — at your desk, in the canteen queue, on the way home — you spend a unit of cognitive resource that could have been used for a decision that matters. Professionals who meal prep have eliminated 10–15 food decisions per week from their mental load.
Beyond the mental efficiency argument, meal prep puts you in complete control of your macros. You are not at the mercy of whatever the office canteen decided to serve or whether the restaurant has a high-protein option. You know exactly what you're eating and exactly how it fits your targets.
The 90-minute Sunday protocol
Set rice cooker (3 cups), season and oven-prep proteins, chop vegetables

Assemble meal containers while everything is still warm
Label containers (Mon–Fri), refrigerate lunches, freeze anything beyond Thursday
Equipment you actually need
What to prep each week
Proteins (batch cook): Chicken breast (whole or sliced), lean mince (beef or turkey), salmon fillets, eggs. Two to three proteins per week gives variety without complexity.
Carbohydrates (batch cook): White rice (digests quickly, gym-friendly), sweet potato, oats. A rice cooker handles this while you do everything else.
Vegetables (prep, don't necessarily cook): Broccoli (blanch and freeze), mixed leaves (just wash), cherry tomatoes, cucumber. These can be added cold to your containers.
Snacks (portion): Greek yoghurt (200g), cottage cheese (150g), almonds (30g portions), protein bars for travel days.
