The 3pm biscuit raid is rarely a willpower problem. It's a lunch problem: a sandwich-and-crisps lunch is mostly fast carbs, so it burns off by mid-afternoon. Protein and fibre are what carry you to dinner.
Why protein at lunch changes the afternoon
Protein and fibre digest slowly, steadying energy and appetite. A lunch built on legumes, eggs, fish or tofu means the afternoon runs on fuel rather than fumes.
Prep-ahead high-protein lunches
Frittata slices
Eggs and whatever vegetables need using; travels well, eats at room temperature.
Chicken or tofu grain bowls
Batch-roast protein on Sunday, assemble over couscous all week.
Bean salads with intent
White beans, tuna or chickpeas, sharp dressing, sturdy vegetables that don't wilt.
The desk-drawer option
Prep-ahead fails the week you need it most. The backup that never fails: a shelf-stable, legume-based bowl in your desk. fiid bowls are high in protein and fibre, need no fridge, and heat in 90 seconds, faster than the kettle queue. The high-protein range covers four flavours so the backup doesn't get boring.
The forgot-everything fallback (shop version)
If you're buying on the day: choose the option with visible legumes, eggs or fish over the meal deal default, and add fruit rather than crisps. Imperfect beats hungry.
