A default choices library is a short, written list of decisions you make once, ahead of time, so you do not have to make them again every day: what breakfast usually is, when the family walks, what time screens go off, when lights go out. Defaults reduce decision fatigue and make the healthy option the one that happens automatically. You can still change a default on any given day; you just do not have to think about it when you do not want to.
This guide shows how to build a library for four areas: meals, movement, bedtimes and screens. It works for individuals and for whole households.
Why pre-deciding helps
Many of the choices that shape weight and energy are made when you are tired, hungry or rushed: what to make for dinner at 6 p.m., whether to go for a walk after a long day, whether to watch one more episode. In those moments the easiest option usually wins. A default changes which option is easiest.
Defaults also lower friction in families. When “Tuesday is tacos” and “screens off at 8:30” are simply how the house runs, there is less negotiating every night.
How to build your library
- Pick the decisions that cause the most stress. For most people this is weeknight dinners, evening screens and bedtime.
- Write one default for each. Keep it specific: a meal, a time, a place.
- Add one backup. A second option for days the first one will not work.
- Post it somewhere visible. The fridge, a shared family calendar or a note on your phone.
- Review once a month. Keep what works, swap what does not.
Meal defaults
Canada’s Food Guide suggests filling half your plate with vegetables and fruits, a quarter with whole grain foods and a quarter with protein foods, and notes that this pattern works for bowls, lunch boxes and shared platters too (Health Canada, Make healthy meals with the eat well plate). Use it as the template for your defaults.
| Meal | Default | Backup |
|---|---|---|
| Weekday breakfast | Oatmeal with berries and a spoon of nut butter | Whole grain toast, eggs and an apple |
| Lunch | Leftovers from last night plus raw vegetables | Bean and vegetable soup with a whole grain roll |
| Afternoon snack | Yogurt and fruit | Hummus and carrot sticks |
| Weeknight dinner | A theme for each night (see below) | A freezer meal or sheet-pan chicken and vegetables |
| Drink with meals | Water | Milk or sparkling water |
Theme nights make dinner defaults easy for a family: Monday soup, Tuesday tacos, Wednesday stir-fry, Thursday pasta with vegetables, Friday homemade pizza. Our guide to theme days has more ideas, and buffer meals cover the nights when even the theme is too much.
Make the default the easy option at home
- Keep a washed fruit bowl on the counter and cut vegetables at eye level in the fridge.
- Store treats in an opaque container on a higher shelf.
- Put water bottles or a jug of water out where everyone can reach it.
- Pre-portion snacks into small containers once a week.
Movement defaults
The Public Health Agency of Canada recommends that adults aged 18 to 64 get at least 2.5 hours of moderate to vigorous activity per week, in bouts of 10 minutes or more, plus muscle- and bone-strengthening activities at least two days a week. It also suggests scheduling a regular time and place for activity and inviting someone to join you (Physical activity tips for adults). Defaults are a simple way to build that schedule.
- Daily default: a 15-minute walk after dinner, as a family if possible.
- Strength default: Monday and Thursday, 20 minutes of bodyweight exercises before breakfast.
- Weekend default: one active outing on Saturday morning: a hike, a bike ride, skating or swimming.
- Bad-weather backup: a dance video, indoor stairs or a mall walk.
- Getting around: walk or bike for trips under 2 km when it is safe to do so.
For children, make active play the default after school before any screen time. Keep balls, skipping ropes and bikes by the door rather than in the back of the garage.
Bedtime defaults
The U.S. Centers for Disease Control and Prevention recommends at least seven hours of sleep for adults aged 18 to 60, and suggests going to bed and waking at the same time each day and keeping the bedroom quiet, relaxing and cool (CDC, About Sleep).
- Lights-out default: pick a time and count back seven to eight hours from your wake-up time.
- Wind-down default: 30 minutes before lights out, start the same short routine: tidy the kitchen, set out tomorrow’s clothes, wash up, read.
- Weekend default: keep wake-up time within about an hour of weekdays.
- Evening drink default: water or a caffeine-free herbal tea.
For children, a consistent bedtime routine (bath, pyjamas, teeth, story, lights out) is one of the most useful defaults a family can have. Ask your child’s healthcare provider how much sleep is right for their age.
Screen defaults
The same CDC guidance suggests turning off electronic devices at least 30 minutes before bed. Screen defaults also free up time for meals together and movement.
- Screen-free zones: the dinner table and bedrooms.
- Screen-free times: meals, the first 30 minutes after waking and the last 30 to 60 minutes before bed.
- Charging station: all phones and tablets charge overnight in the kitchen, not in bedrooms.
- Default replacement: a basket of books, puzzles or board games in the living room.
- Weekend default: one screen-free family activity each weekend.
Adults set the tone here. If phones stay off the table for parents too, children are far more likely to accept the rule.
Talking about defaults with your family
- Explain the why in a sentence. “We put phones away at dinner so we can actually talk.”
- Offer choices within the default. “It is fruit for snack. Do you want an apple or grapes?”
- Stay calm about pushback. Hold the default kindly and consistently. Resistance usually fades once it becomes routine.
- Let older children help design it. Teenagers are more likely to follow a screen default they helped choose.
A sample one-page library
- Breakfast: oatmeal and fruit (backup: eggs and toast)
- Lunch: leftovers plus vegetables
- Dinner: theme nights; Friday is pizza night
- Drinks: water at meals
- Movement: walk after dinner; strength Monday and Thursday
- Screens: off at dinner and by 9 p.m.; phones charge in the kitchen
- Bedtime: wind-down at 10 p.m., lights out 10:30 p.m.
Key takeaways
- Decide once, ahead of time, and write it down.
- Start with the decisions that cause the most daily stress.
- Give every default a backup for difficult days.
- Arrange your home so the default is the easiest option.
- Review your library monthly and adjust as seasons and schedules change.
