Water is one of the most important nutrients for human life, yet it’s often the most neglected. Every cell, tissue and organ in the body depends on adequate hydration to function properly. At Younger Longer, we emphasise that something as simple as drinking enough fluids each day can have a powerful impact on energy levels, physical performance, cognitive function and long-term health. Why Hydration Matters The human body is made up of roughly 50–70% water, depending on age, sex and body composition. Water is essential for many vital processes, including: • Regulating body temperature • Transporting nutrients and oxygen • Supporting digestion and nutrient absorption• Removing waste products through urine and sweat• Maintaining healthy joints and tissues• Supporting brain function and concentration Even mild dehydration - around 1–2% loss of body weight through fluid loss - can lead to reduced physical performance, fatigue, headaches and impaired concentration. How Much Water Do We Need? Fluid needs vary depending on body size, physical activity and environmental conditions. Current Australian health guidelines suggest that average daily fluid intake should be approximately: Adults• Men: Around 2.6 litres of fluids per day• Women: Around 2.1 litres of fluids per day These totals include fluids from drinks, with additional water coming from foods such as fruit and vegetables and vary depending on environmental temperature, activity levels and a slew of other factors. Children require slightly less but still need regular fluid intake throughout the day. For example: • Ages 1–3: About 1 litre of fluids daily• Ages 4–8: About 1.2 litres daily • Adolescents: 1.6–1.9 litres dailyFluid requirements increase when people are:• Physically active• Exercising in warm or humid conditions• Living in hot climates• Pregnant or breastfeedingHydration and AgeingHydration becomes even more important as we age. Older adults often experience a reduced sense of thirst, which means they may not drink enough fluids even when the body needs them. In addition, age-related changes in kidney function can make fluid balance more delicate.Poor hydration in older adults has been associated with: • Fatigue and dizziness• Reduced concentration and cognitive performance• Constipation• Increased risk of falls• Kidney problems and urinary tract infections Maintaining regular fluid intake throughout the day can help prevent these issues. How to Tell If You’re Well Hydrated One simple way to monitor hydration is by checking urine colour. • Pale yellow or straw-coloured urine usually indicates good hydration.• Dark yellow urine may suggest you need more fluids. Another helpful habit is to drink regularly rather than waiting until you feel thirsty, as thirst is often a late signal that the body is already slightly dehydrated. What Should You Drink?  Water remains the best and most reliable source of hydration.  Other drinks can also contribute to fluid intake, including:• Milk• Herbal teas• Soups• Sparkling water While fruit juices and soft drinks contain fluids, they often contain large amounts of sugar and should be consumed in moderation. For most people, plain water should make up the majority of daily fluid intake. Hydration and Physical Activity Exercise increases fluid loss through sweat, particularly in warm conditions. During prolonged exercise, the body may lose 1–3 litres of fluid per hour, depending on intensity, temperature and individual sweat rates.Replacing lost fluids before, during and after exercise helps maintain performance, prevent overheating and support recovery. The Younger Longer Perspective Hydration is one of the simplest habits you can improve to support long-term health. Adequate fluid intake helps maintain energy, mental clarity, digestive health and physical performance. Yet many people move through the day mildly dehydrated without realising it. A simple strategy is to keep water easily accessible throughout the day - on your desk, in your bag, or beside you when exercising.  Small habits like this can make a significant difference over time.  Sometimes the most powerful health strategies are also the simplest and staying properly hydrated is one of the easiest ways to support your body to live Younger Longer.

Many people talk about wanting to “lose weight,” but modern health science focuses on something more important: Reducing excess body fat while preserving muscle. This distinction matters. When people follow extreme diets, fasts or unsustainable eating plans, the weight they lose often comes from water and muscle, not just fat. Unfortunately, muscle loss slows metabolism and makes long-term weight maintenance much harder.At Younger Longer, the goal is not simply to weigh less - it’s to improve body composition, meaning; less body fat and more metabolically active muscle. This approach supports energy, mobility, metabolic health and longevity.Here are 10 evidence-based strategies that can help reduce body fat in a sustainable way.1. Move More Throughout the DayRegular physical activity remains one of the most effective ways to reduce body fat and maintain long-term weight loss.Both aerobic exercise and resistance training play important roles. Aerobic exercise burns energy during activity, while strength training helps preserve muscle mass and metabolic rate.In addition, small daily movements (often referred to as “incidental exercise”) - walking more, taking stairs, standing frequently - contribute significantly to total energy expenditure.2. Pay Attention to Hunger and FullnessLearning to recognise true hunger and satiety signals can help prevent overeating.Eating slowly and stopping when comfortably satisfied, rather than overly full, supports healthier energy balance. Mindful eating practices have been shown to improve weight management and reduce emotional eating. 3. Maintain Regular Eating PatternsSkipping meals can sometimes lead to excessive hunger later in the day, which may increase the likelihood of overeating.Many people find it helpful to eat regular, balanced meals that include protein, fibre and healthy fats to maintain steady energy levels. While breakfast timing varies between individuals, starting the day with a balanced meal can improve appetite regulation for some people. 4. Slow Down When You EatIt takes time for the brain to receive signals that the stomach is full. Eating meals slowly, ideally 20 minutes or more, allows appetite hormones such as leptin and cholecystokinin to signal satiety, which can reduce overall calorie intake. Simply slowing down your eating pace is one of the easiest strategies to prevent overeating.5. Choose Healthy Fats - But Be Mindful of Portions Dietary fat is an essential nutrient and should not be eliminated. However, fats are energy dense, meaning they contain more calories per gram than carbohydrates or protein. Focus on healthy unsaturated fats such as those found in:• Olive oil • Nuts and seeds • Avocado• Fatty fishAt the same time, limit (and ideally eliminate) trans fats and highly processed foods that contain unhealthy fats.6. Include Adequate ProteinProtein plays an important role in fat loss by helping preserve muscle mass and promoting satiety. Research shows that higher protein intake, coupled with resistance training, during weight loss helps reduce muscle loss and may improve metabolic health. Healthy protein sources include:  • Fish • Lean meat • Eggs • Greek yoghurt • Legumes • Tofu and plant-based proteins7. Choose Higher-Quality CarbohydratesCarbohydrates remain an important energy source, especially for active individuals. Rather than eliminating carbohydrates, focus on minimally processed, fibre-rich options, such as: • Whole grains• Legumes • Fruit • Vegetables • Natural dairy productsLimiting (and ideally eliminating) ultra-processed carbohydrates - such as sugary drinks, sweets and refined snack foods - can significantly improve dietary quality. 8. Increase Fibre IntakeDietary fibre slows digestion, improves satiety and supports gut health. Higher fibre intake has consistently been associated with improved weight management and metabolic health. Excellent sources of fibre include:  • Vegetables • Whole grains • Legumes • Fruit • Nuts and seeds 9. Limit Alcohol Consumption Alcohol contains significant calories but provides little nutritional benefit. It can also reduce fat metabolism and increase appetite, making fat loss more difficult. Reducing alcohol intake is one of the most effective ways to improve energy balance and metabolic health. 10. Address Emotional Eating Food is often used as a coping mechanism during times of stress, boredom or emotional difficulty. Developing alternative strategies for managing emotions such as exercise, social support, relaxation techniques or professional counselling can help break the cycle of emotional eating. How Much Fat Loss Is Healthy? Sustainable fat loss tends to occur gradually. Many health professionals suggest aiming for approximately 0.5 to 1 kilogram per week, although this varies depending on starting weight age and activity levels. More importantly, even modest reductions in body weight can deliver meaningful health benefits. Research shows that losing 5–10% of body weight can significantly improve:  • Blood pressure• Cholesterol levels• Blood sugar control• Joint health• Energy levels In other words, you don’t need to reach an “ideal” weight to experience major health improvements. The Younger Longer PerspectiveHealthy fat loss isn’t about extreme diets or short-term fixes. It’s about building sustainable habits that improve metabolism, maintain muscle and support long-term health.By combining regular movement, balanced nutrition, adequate sleep and stress management, you can improve body composition and protect your health for decades to come. Remember, comes to longevity, the goal isn’t simply to lose weight - it’s to build a body that stays strong, capable and healthy for life. And that’s what living Younger Longer is all about.
