Why Do People Gain Weight in Winter — And How Can You Lose It?

6
August 2025

As winter sets in, it is natural for our routines to shift. With less outdoor activity, more time spent indoors, and a tendency to reach for comfort foods, it is common to notice a few extra kilos creep on during the colder months. If you are trying to lose weight and maintain a healthy lifestyle, small, consistent habits can make a meaningful difference.
Read on for practical tips and resources to support your wellbeing and weight goals this winter.

🔄 Why Do We Gain Weight in Winter?
Colder weather can lead to:
• Reduced physical activity due to shorter days and colder mornings.
• Increased appetite and cravings for heavier meals and snacks.
• Lower mood and motivation, which may affect energy and healthy habits.

📏 What is a Healthy Weight for You?
A good starting point is understanding your Body Mass Index (BMI) — a calculation based on height and weight.
You can check yours using this free calculator:

Keep in mind: BMI is only a general guide. Other factors like waist measurement, muscle mass, age, and overall health are important too.
You can refer to the Australian Dietary Guidelines for evidence-based recommendations on daily energy needs, healthy eating patterns, and lifestyle habits that support weight management.

❄️ Tips for Healthy Winter Weight Management
• Stick to a meal routine – Plan balanced meals with lean protein, fibre-rich vegetables, and wholegrains.
• Choose comfort foods wisely – Try homemade soups, slow-cooked stews with extra vegetables, or roasted root vegetables instead of takeaways. If you do eat takeaway foods, try to select healthier food options from menus and avoid eating fatty fried foods.
• Keep moving – Even short indoor workouts, brisk walks, or stretching routines help burn energy and lift your mood.
• Stay hydrated – We often forget to drink water in winter, which can increase hunger signals. Hydration is essential for energy, digestion and metabolism.
• Limit kilojoule-dense drinks – Cut back on creamy coffees, alcohol, and soft drinks when possible.

💊 What Weight Loss Medications Are Prescribed in Australia?

In Australia, GLP-1 receptor agonists such as Ozempic (semaglutide) and Wegovy are increasingly prescribed to support weight loss in eligible patients. These medications:
• Help regulate appetite and improve blood sugar control.
• Are typically prescribed to individuals with a BMI of 30 or higher, or 27 and above if they have related health conditions (such as type 2 diabetes, high blood pressure, or sleep apnoea).
• Must be prescribed and monitored by a doctor
• Are used in combination with dietary changes, increased physical activity, and lifestyle support as part of a comprehensive weight management plan.
📌 Note: These medications are not suitable for everyone. It is important to speak with a GP to assess your health, goals, and suitability before starting treatment.
