Water plays a crucial role in fat burning, digestion, and metabolism. Many people don’t drink enough, and that can slow down weight loss.
Staying hydrated helps your body function at its best, making it easier to burn kilojoules, control hunger, and improve overall health.
Metabolism is how your body converts food into energy. The faster your metabolism, the more kilojoules you burn—even while resting.
Medical Research published in the Journal of Clinical Endocrinology & Metabolism shows that drinking 500ml of water can increase metabolism by up to 30% for about 40 minutes. This means your body burns more energy after drinking water—a simple but effective weight-loss tool.
Water is also key to fat oxidation, the process of breaking down stored fat for energy. Without enough hydration, your body struggles to burn fat efficiently.
Proper water intake ensures your metabolism runs smoothly and helps your body shed extra weight.
Hunger and thirst can feel similar, making it easy to mistake dehydration for hunger. This can lead to unnecessary snacking when all your body really needs is water.
Drinking 500ml of water before meals has been shown to help people eat fewer kilojoules and lose more weight.
A study in Clinical Nutrition Research found that drinking water before meals reduced overall calorie intake, making it easier to maintain a calorie deficit.
Water also reduces sugar cravings. When you're dehydrated, your body may signal low blood sugar, leading to cravings for sweets and processed snacks.
Staying hydrated helps balance your energy levels and prevents unnecessary snacking.
Hydration plays a big role in digestion. Drinking enough water helps break down food, absorb nutrients, and prevent bloating.
Without enough water, digestion slows down, leaving you feeling sluggish and uncomfortable.
Water is also essential for preventing constipation. While fibre is great for digestion, it needs water to work properly.
Without hydration, fibre can actually cause bloating instead of promoting healthy digestion.
Water needs vary, but a good starting point is 2–3 litres per day. If you exercise, sweat more, or live in a hot climate, you’ll need even more.
Wondering if you’re drinking enough? A simple test is checking your urine colour:
Try to drink consistently throughout the day instead of waiting until you feel thirsty, as thirst is often a sign of mild dehydration.
