Canadian winters bring shorter days, less movement and more comfort food, so many people gain weight between November and March. Planning indoor exercise, embracing winter activities, keeping meals structured through the holidays, and supporting mood and vitamin D make winter weight loss achievable.
- Daily step counts often drop by thousands in winter.
- Winter sports such as skating, snowshoeing and skiing burn plenty of calories.
- Most Canadians benefit from vitamin D in winter.
Research shows many adults gain weight over the winter holidays and do not fully lose it afterwards, contributing to gradual weight gain over the years. In Canada, the long, cold season makes this even more of a challenge. Here is how to keep making progress until spring.
Why winter is harder
- Less daily movement: fewer walks, more driving, more time indoors.
- Shorter days: less daylight affects mood, energy and sleep timing.
- Comfort eating: heavier meals, baking and holiday treats.
- Holidays: parties, alcohol and disrupted routines from mid-December to early January.
- Seasonal mood changes: low mood can reduce motivation and increase cravings.
Keep moving indoors
Plan your indoor options before the weather turns. Gyms and community centres offer weights, cardio machines, indoor tracks and pools. At home, a set of dumbbells, resistance bands and a stationary bike or rower cover most needs. Many Canadian malls open early for walkers, and underground networks in cities such as Toronto and Montreal make walking possible in any weather. Aim to keep your daily step count close to your summer average; see daily movement.
Embrace winter activities
| Activity (1 hour, 75 kg adult) | Approximate calories |
|---|---|
| Snowshoeing | 400–600 |
| Cross-country skiing | 500–800 |
| Skating (recreational) | 350–500 |
| Downhill skiing or snowboarding | 300–450 |
| Shovelling snow | 350–500 |
| Winter hiking | 400–550 |

Eating well in winter
Winter food does not have to derail progress. Soups, stews and chili made with lean meat, legumes and vegetables are filling and lower in calories than creamy dishes. Root vegetables, squash and frozen produce are affordable and nutritious. Batch cooking on weekends keeps healthy meals ready for busy, dark weeknights. See meal prep ideas.
Navigating the holidays
- Aim to maintain rather than lose weight from mid-December to New Year.
- Eat a protein-rich meal before parties to avoid arriving starving.
- Choose the treats you really enjoy and skip the rest.
- Alternate alcoholic drinks with water.
- Keep at least a few workouts and daily walks in your schedule.
- Get back to your normal routine within a day or two of each event.
A sample winter week
Monday, Wednesday and Friday: 45-minute strength sessions at the gym or at home. Tuesday: indoor cycling or a swim. Thursday: a brisk 40-minute walk at lunch, in a mall or indoor track if the weather is bad. Saturday: a winter activity such as skating, snowshoeing or cross-country skiing with family or friends. Sunday: a long walk and batch cooking for the week. Daily: aim for your usual step count, using short walks after meals. This kind of plan keeps activity high even when outdoor conditions are poor.
Staying motivated in the dark months
Winter goals help: a spring race, a summer hike, or a strength target. Training with a friend or joining a class adds accountability on cold, dark mornings. Laying out gym clothes the night before and scheduling sessions like appointments reduce the chance of skipping. Remember that maintaining your weight through the holidays is a real success, not a failure.
Mood, light and vitamin D
Seasonal affective disorder (SAD) affects a meaningful number of Canadians, and many more experience milder winter blues. Daylight exposure, especially morning light, regular exercise and social contact help. Light therapy lamps can be effective for SAD; talk to your doctor. Vitamin D production from sunlight is minimal in winter across most of Canada, and Health Canada and Osteoporosis Canada suggest many adults take a supplement. See sleep and recovery.
Winter safety
- Dress in layers and protect hands, feet and face from frostbite.
- Use traction aids such as ice cleats on icy paths.
- Warm up thoroughly before outdoor exercise.
- Stay hydrated; cold air is dry and you still sweat.
- Check wind chill warnings from Environment Canada before going out.
