Frequently Asked Questions

While the popular "eight glasses a day" rule provides a useful baseline, individual water needs vary significantly based on body size, activity level, climate, and overall lifestyle. A more practical approach is the "pale urine" method—aiming for pale yellow urine indicates adequate hydration for most people. Generally, adults need between 2 to 3.7 litres daily, though this includes water from foods and beverages.

If you exercise regularly, live in a hot climate, or are pregnant or breastfeeding, your water requirements increase. Rather than obsessing over exact amounts, focus on drinking consistently throughout the day, drinking when thirsty, and adjusting based on your activity and environment. Herbal teas, water-rich fruits and vegetables, and even coffee and tea contribute to your daily fluid intake.

Healthy fats, primarily unsaturated fats, support brain function, nutrient absorption, and overall cell health. These include monounsaturated fats found in olive oil, avocados, and nuts, plus polyunsaturated fats (especially omega-3 fatty acids) in fatty fish, flaxseeds, and walnuts. These fats actually support cardiovascular health and can help maintain stable energy levels throughout the day.

Unhealthy fats—primarily trans fats and excessive saturated fats—may contribute to inflammation and negatively impact various body systems. Trans fats, often found in processed foods and fried items, should be minimized. Saturated fats from sources like butter and fatty meats are best consumed in moderation. The key is balancing your fat intake, choosing whole-food sources, and being mindful of portion sizes rather than eliminating fats entirely.

Reading food labels and choosing cooking methods like baking or steaming over deep frying helps you maintain a healthier fat intake. A practical guideline is that 20-35% of your daily calories should come from fats, with most coming from unsaturated sources.

The optimal macronutrient balance varies by individual goals and lifestyle, but a practical starting point is 40-50% carbohydrates, 20-30% protein, and 20-35% fats. However, your ideal balance depends on your activity level, metabolism, and personal preferences. Someone who exercises intensively may benefit from higher protein intake, while those with sedentary lifestyles might adjust accordingly.

A simple approach is to build each meal around these three components: include a palm-sized serving of lean protein (fish, poultry, legumes, or dairy), a fist-sized portion of whole grains or starchy vegetables, and a thumb-sized serving of healthy fats (nuts, seeds, or oils). This visual method removes the need for complicated calculations and helps you maintain balance intuitively.

Rather than strictly adhering to one formula, experiment with different ratios to see how your body responds. Pay attention to your energy levels, digestion, and overall sense of wellbeing. Working with a professional nutritionist can help you identify the balance that works best for your unique circumstances and goals.

Snacking itself is neither inherently good nor bad—what matters is what you snack on and how frequently you snack. Strategic snacking between meals can help maintain stable blood sugar, prevent overeating at main meals, and support sustained energy levels throughout the day. The key is choosing nutrient-dense options like fresh fruit, nuts, yoghurt, vegetables with hummus, or cheese.

Ultra-processed snacks high in sugar and refined carbohydrates can lead to energy crashes, cravings, and poor dietary habits. If you find yourself constantly reaching for snacks due to boredom or stress rather than genuine hunger, it may indicate that your main meals lack sufficient nutrients or that emotional eating patterns need addressing through mindfulness practices.

A practical approach is to listen to your body's hunger cues and snack only when genuinely hungry, choosing whole foods whenever possible. Planning your snacks ahead—similar to meal planning—helps you make intentional choices rather than defaulting to convenient processed options. Some people thrive with three meals and two snacks, while others do better with just three main meals; the right pattern depends on your individual needs.

Nutrition labels provide standardised information, but understanding them requires knowing where to focus. Start by checking the serving size—all the nutritional information listed is per that serving, not necessarily per entire package. Then look at calories and the macronutrient breakdown (protein, carbohydrates, fats), comparing these to your daily targets. Pay attention to added sugars separately from total carbohydrates, aiming to keep added sugars minimal.

The ingredient list, usually on the back of the package, is equally important. Ingredients are listed by weight in descending order, so if sugar appears in the first three ingredients, the product is likely high in added sugars. Look for familiar whole-food ingredients and be cautious of long lists of additives, preservatives, and artificial ingredients. Using the "5-ingredient rule"—choosing products with five or fewer recognisable ingredients—can simplify your shopping decisions.

Be aware of marketing claims like "natural," "wholesome," or "made with real fruit," which are not standardised and may be misleading. Instead, rely on the actual nutrition facts and ingredient list. Comparing labels between similar products helps you make informed choices and identify products that best align with your dietary goals and preferences.

Meal timing and frequency have less impact on overall nutrition than the total quality and quantity of food consumed throughout the day. Contrary to older beliefs about "revving metabolism" with frequent meals, research shows that what matters most is your total calorie and nutrient intake, not when or how often you eat. Some people thrive eating three meals daily, while others prefer smaller, more frequent meals—both approaches work if nutrient needs are met.

Eating breakfast is often recommended because it can help with concentration and reducing overeating later in the day, but skipping breakfast isn't harmful if you're not hungry or prefer eating later. Similarly, eating close to bedtime is fine as long as you're not overeating or experiencing digestive discomfort. The ideal pattern depends on your work schedule, activity level, and personal preference.

What's genuinely important is spacing meals enough that you arrive at each meal genuinely hungry but not ravenous, which helps with portion control and digestion. Eating mindfully, without rushing, and stopping when satisfied (not stuffed) matters far more than following strict timing rules. Experiment with different eating schedules and notice which feels most sustainable and leaves you feeling energised throughout the day.

Maintaining healthy habits while dining out or travelling requires planning and flexibility. Before visiting a restaurant, check the menu online to identify nutritious options and make your decision ahead of time, reducing the chance of impulse choices. When ordering, don't hesitate to make requests—ask for dressings on the side, request grilled instead of fried preparations, or substitute chips for vegetables. Most restaurants accommodate reasonable requests.

Portion sizes at restaurants are often excessive; consider sharing a main course, taking half home for later, or starting with an appetiser instead of a large entrée. Being mindful while eating helps you notice fullness cues despite distracting environments. If travelling, pack portable nutritious snacks like nuts, fruit, or protein bars to avoid relying entirely on airport or convenience store options.

Remember that occasional indulgences don't derail your overall habits—one meal or a few days of eating differently won't undo months of consistency. Adopting a flexible, non-restrictive mindset toward eating out helps you enjoy social occasions and travel experiences while still generally prioritising nutritious choices. The goal is progress, not perfection.

Meal planning provides numerous benefits including saving time and money, reducing food waste, supporting consistent nutrition, and eliminating daily decision fatigue about what to eat. When you plan ahead, you're more likely to cook at home rather than relying on takeaway, and you can intentionally include a variety of nutrient-dense foods throughout the week. It also helps you make balanced meals containing adequate protein, vegetables, and whole grains.

To begin meal planning, start simple by planning just three days at a time rather than overwhelming yourself with a full week. Choose five or six base proteins you enjoy (chicken, fish, beans, tofu, etc.), then plan simple meals around them paired with vegetables and grains. Make a shopping list based on your planned meals, which helps you stick to your budget and avoid impulsive purchases of processed foods.

Batch cooking on weekends—preparing several components that you can mix throughout the week—saves significant time and ensures you always have ready-to-eat nutritious options. You don't need complicated recipes; simple combinations of grilled chicken with roasted vegetables and brown rice repeated a few times weekly work perfectly. As you become comfortable, gradually expand your variety. The key is consistency and keeping the process simple enough to maintain long-term.

Nutritional requirements shift throughout life based on growth, metabolism, and lifestyle. Children require higher calorie density to support rapid growth, while teenagers need increased calcium for bone development and protein for muscular development. Adult women typically need fewer calories than men due to differences in muscle mass, though individual variation is significant. During pregnancy and breastfeeding, calorie and nutrient needs increase substantially.

As people age, calorie needs generally decrease due to natural muscle loss, but nutrient density becomes increasingly important. Older adults require adequate protein to maintain muscle mass, sufficient calcium and vitamin D for bone health, and B vitamins for cognitive and neurological function. Meanwhile, activity level dramatically influences calorie and protein requirements—athletes and highly active individuals need substantially more calories and protein than sedentary people of the same age and size.

Rather than following one-size-fits-all guidelines, assess your individual situation: your age, gender, activity level, and any specific health considerations. This helps you adjust portion sizes and nutrient distribution to match your unique needs. Regular check-ins with your body's responses—energy levels, strength, recovery from exercise—provide valuable feedback about whether your current nutrition is appropriate.

Breaking unhealthy eating patterns begins with identifying triggers—are you eating out of stress, boredom, habit, or genuine hunger? Once you recognise your patterns, you can implement practical strategies like managing stress through exercise or meditation, keeping trigger foods out of the house, or establishing alternative responses (drinking water, taking a walk) when cravings strike. Understanding the "why" behind eating behaviours is crucial for lasting change.

Rather than trying to overhaul everything at once, change one habit at a time. Perhaps you start by replacing sugary drinks with water, then gradually add more vegetables to meals, then establish a consistent breakfast routine. Small, incremental changes feel less overwhelming and are more likely to become permanent. Keeping a food journal for a week or two helps you identify patterns and see which changes would have the biggest positive impact.

Building new habits requires repetition and patience—research suggests it takes 66 days on average for a behaviour to become automatic, though this varies by person. Be compassionate with yourself when you slip into old patterns; occasional lapses are normal and don't erase progress. Celebrating small victories and progress keeps motivation high. If emotional eating is significant, consider working with a therapist alongside nutritional guidance to address underlying emotional patterns.

Micronutrients—vitamins and minerals—are essential for nearly every bodily function despite being needed in smaller quantities than macronutrients. They support immune function, energy production, bone health, cognitive development, and countless enzymatic reactions throughout your body. For example, iron is crucial for oxygen transport, calcium and vitamin D support bone health, B vitamins help convert food into energy, and antidependent's vitamin C supports immunity and collagen formation.

Rather than memorising every micronutrient, focus on eating a varied, colourful diet with plenty of whole foods. Different colours indicate different micronutrients—orange vegetables contain beta-carotene, dark leafy greens provide iron and calcium, berries contain antioxidants. Eating the full spectrum of colours ensures you're getting diverse micronutrients. If you follow restrictive diets, have specific health considerations, or consistently feel fatigued despite adequate sleep, a nutritionist can assess whether supplementation is appropriate.

Supplementing indiscriminately without identifying actual deficiencies is unnecessary and can be wasteful. A blood test can identify specific deficiencies, allowing targeted supplementation. For most people following reasonably balanced diets with whole foods, adequate micronutrients are obtained through food. However, certain populations—vegans, older adults, pregnant women—may benefit from targeted supplementation to ensure they're meeting their specific needs.
