As a new year begins, many people take time to reflect on their health and wellbeing. Periods like Christmas and New Year often bring changes to routine, including sleep, physical activity, stress levels, social commitments, and eating patterns. It is very common for these shifts to affect energy levels, fitness, and body weight.
Across Australia, weight-related health concerns are common. According to the Australian Institute of Health and Welfare, around two in three Australian adults are living with overweight or obesity. This highlights that weight management is a widespread health issue, not an individual shortcoming.
If you have noticed changes in your weight over the holiday period, you are not alone. Weight is influenced by a range of factors, including diet, physical activity, sleep, stress, hormones, medications, and life stage. While diet does play an important role in weight and metabolic health, it is only one part of a much broader picture.
At Qualitas Medical Practice, we want to reassure you that weight management does not need to feel stressful, extreme, or driven by guilt. The New Year is not about punishment or rigid rules. It is an opportunity to gently return to supportive routines and focus on long-term health and wellbeing in a sustainable way.
Weight management is a health consideration, not a personal failing. For many people, achieving and maintaining a healthy weight is challenging, particularly when excess weight is linked with chronic conditions. This is why guidance from a qualified healthcare professional is important to ensure any approach to weight management is safe, appropriate, and tailored to your individual health needs.
Understanding Overweight and Obesity
Overweight and obesity refer to having excess body weight that may increase the risk of certain health conditions. At a population level, excess weight is associated with a higher risk of chronic conditions such as heart disease, type 2 diabetes, joint problems, and some cancers, as well as higher rates of premature death (AIHW, 2019).
Clinically, overweight and obesity are commonly assessed using:
- Body Mass Index (BMI), which looks at weight relative to height
- Waist circumference, which helps identify health risks related to abdominal fat
These tools are not about judgment. They are screening measures used to identify when weight may be affecting health and when additional support could be beneficial.
A GP can help interpret these measures in the context of your overall health, medical history, age, and individual circumstances.
For more information, see Measuring overweight or obesity.
Checking Your BMI
BMI can be calculated using an online calculator or with the following formula:
BMI = weight (kg) ÷ [height (m) × height (m)]
- Underweight: below 18.5
- Healthy weight: 18.5–24.9
- Overweight: 25–29.9
- Obese: 30 or above
BMI can provide a general guide, but it does not tell the whole story. A GP assessment allows for a more personalised and meaningful discussion about health goals and options.
Weight and Health in Australia
Weight-related health concerns are common across Australia, meaning many individuals and families are navigating similar challenges.
Australian data shows:
- 66% of adults aged 18 and over are living with overweight or obesity
- 26% of children and adolescents aged 2–17 are living with overweight or obesity
In 2018–19:
- 74% of Aboriginal and Torres Strait Islander adults
- 38% of Aboriginal and Torres Strait Islander children and adolescents
were living with overweight or obesity.
Excess weight increases the risk of chronic conditions such as heart disease, type 2 diabetes, joint pain, sleep problems, and some cancers. These conditions often develop gradually, which means that even small, supported lifestyle changes can have meaningful long-term benefits.
Weight Is Influenced by Many Factors
Weight is not simply about “willpower” or food choices. It is influenced by a combination of:
- Genetics
- Hormones and metabolism
- Sleep and stress
- Medications
- Mental health
- Work and family demands
- Life stages such as pregnancy, menopause, or ageing
Understanding this can help remove guilt and support a more compassionate, realistic approach to change.
Understanding Energy In and Energy Out
A simple way to think about weight management is through the concept of energy balance. This means your body weight is influenced by the calories you consume from food (energy in) and the energy your body uses for activity and daily functions (energy out).
Even small changes in either area can support a healthy weight:
- Choosing slightly smaller portions or swapping sugary drinks for water can reduce energy IN.
- Increasing daily movement, like walking, taking stairs, or gardening, increases energy OUT.
This approach helps people see that sustainable, gradual changes in lifestyle can make a real difference over time without feeling overwhelming (Better Health Victoria, 2023).
A Sustainable Approach to Weight Management
After periods of indulgence, it can be tempting to turn to strict diets or intense exercise programs. These approaches are often difficult to maintain and can feel overwhelming.
A healthier approach focuses on gradual, achievable changes, guided by evidence and individual needs. At Qualitas Medical Practice, weight management support is:
- Individualised: tailored to your health history and circumstances
- Holistic: considering nutrition, activity, sleep, stress, and mental wellbeing
- Evidence-based: focused on long-term health outcomes rather than quick fixes
The goal is not rapid weight loss, but sustainable habits that support health over time.
Eating Well Without Pressure
Healthy eating does not mean giving up all enjoyment or following rigid rules. After the holidays, gently returning to balanced meals can support energy levels and wellbeing. This may include:
- Eating regular meals to reduce overeating
- Increasing vegetables, fruits, and whole grains
- Including lean protein sources
- Gradually reducing sugary drinks and highly processed foods
Trusted Australian resources provide flexible, practical guidance:
Heart Foundation healthy eating resources
- Eating well with high blood pressure
- Eating well for a healthy weight
- Sources of marine and plant-based omega-3
Moving Your Body in Ways That Feel Right
Physical activity supports weight management, heart health, mobility, and mental wellbeing. The most effective activity is the one you can enjoy and maintain:
- Walking, swimming, cycling, or gentle gym sessions
- Strength or resistance exercises a few times per week
- Group classes or active hobbies
The Australian Physical Activity Guidelines recommend activity suited to age, ability, and health status. Even small increases in movement can make a meaningful difference.
Looking After the Whole Person
Weight is influenced by more than diet and exercise alone. Sleep quality, stress, mental health, and daily routines all play an important role.
Programs such as Get Healthy NSW offer free coaching to help people build sustainable, personalised healthy habits. Many people find this additional support makes change feel more achievable.
When Medical Support Is Important
For some people, lifestyle changes alone may not be enough. This is particularly true when excess weight is associated with chronic health conditions such as diabetes, cardiovascular disease, or sleep apnoea. Weight can also be influenced by mental health and emotional wellbeing. Stress, anxiety, depression, trauma, disordered eating patterns, sleep problems, hormonal changes, certain medications, and life stages such as menopause can all affect weight and energy levels. In these situations, support from a GP is especially important.
Weight Management Medications
Some people may be eligible for prescription medications, including GLP-1 receptor agonists, which help regulate appetite. These medications must be prescribed and monitored by a GP to ensure they are appropriate and safe.
Surgical Options
For individuals with severe obesity or obesity-related health conditions, surgical options such as gastric bypass or sleeve gastrectomy may be considered. Surgery is always part of a broader, long-term plan that includes medical follow-up and lifestyle support.
Mental Health & Emotional Wellbeing
Your doctor can assess both physical and mental health factors, provide guidance, and arrange referrals to dietitians, psychologists, exercise physiologists, or specialist services where appropriate.
Setting Kind, Realistic Goals for 2026
Rather than focusing only on the number on the scale, consider goals that support overall health, such as:
- Feeling more energetic
- Improving mobility or joint comfort
- Returning to consistent routines after the holidays
- Supporting mental wellbeing and confidence
Weight is just one measure of health. Daily fluctuations are normal, and progress is often better reflected in how you feel, your energy levels, fitness, or waist measurements rather than frequent weigh-ins.
