Frequently Asked Questions
Metabolic flexibility is the body’s ability to switch between using different sources of energy, primarily carbs and fat, according to factors such as food intake, physical activity and fasting. Good metabolic flexibility is associated with efficient energy regulation and improved metabolic health.
Yes. Although metabolism and muscle mass naturally change with age, healthy lifestyle habits can support metabolic function at any stage of life. Regular exercise, particularly strength training and aerobic activity, a balanced diet, adequate sleep and maintaining a healthy weight, can all contribute to improved metabolic health.
There is no single best exercise. A combination of aerobic activity, strength training and regular everyday movement provides the greatest range of benefits. Strength training is particularly important as you age because maintaining muscle strength supports metabolic health, bone health, mobility and independence.
Eat a predominantly whole-food diet rich in plants and fibre, consume adequate protein, exercise regularly, maintain muscle strength and cardiovascular fitness, get sufficient quality sleep, avoid smoking, manage stress and maintain strong social connections. These habits are more strongly supported by evidence than expensive supplements or unproven longevity treatments.
Changes such as more stable energy levels, improved fitness and exercise recovery, better blood pressure, a healthier waist circumference and improved blood glucose or cholesterol readings indicate improved metabolic health. Rather than focusing on a single measurement, look at trends over time and discuss relevant health markers with your doctor.
Metabolic flexibility is the body’s ability to switch efficiently between using carbohydrates and fat for energy. Maintaining this adaptability supports overall metabolic health as we age.
Lifestyle habits are central to healthy ageing. A balanced, fibre-rich diet, regular physical activity, adequate sleep and effective stress management can all support metabolic health and long-term wellbeing.
What you eat and when you eat both matter. Prioritising whole foods, quality protein, vegetables, whole grains and healthy fats, while limiting ultra-processed foods and sugary drinks, can support metabolic health. Consistent meal timing can also help align eating patterns with the body’s circadian rhythm.
Exercise is one of the most powerful tools for maintaining health span. Combining aerobic activity, strength training, daily movement, balance and mobility work can help preserve muscle, cardiovascular fitness and physical independence as you age.
Consistency is more important than extreme interventions. Sustainable habits maintained over years are more valuable for healthy ageing than restrictive diets, prolonged fasting, or expensive supplements and “biohacking” protocols.
Track meaningful health markers rather than focusing solely on weight. Blood pressure, blood glucose, fitness, waist circumference, sleep, energy levels and strength can provide a broader picture of metabolic and cardiovascular health.
