19. How many kJ does 10,000 steps burn? The number of kilojoules burned by 10,000 steps varies depending on factors such as weight, intensity of steps, and individual metabolism. On average, 10,000 steps can burn approximately 400-600 kilojoules (95-143 calories) for an average-weight person.
20. What exercise burns the most kilojoules? The number of kilojoules burned during exercise depends on factors such as the type of exercise, duration, intensity, and individual characteristics. Generally, high-intensity activities like running, swimming, and cycling tend to burn more kilojoules compared to lower-intensity exercises like walking or yoga.
21. How many kilojoules should a woman have a day? The recommended kilojoule intake for women varies depending on factors such as age, weight, height, activity level, and goals. As a rough estimate, adult women typically require around 7,000-9,000 kilojoules (1,600-2,200 calories) per day, but individual needs may vary.
22. How many calories should I eat a day by age? Calorie needs can vary based on age, gender, weight, height, activity level, and other factors. Here’s a rough breakdown of estimated calorie needs by age group:
    • Children (ages 4-8): 1,200-1,800 calories
    • Older children and adolescents (ages 9-18): Girls – 1,400-2,400 calories, Boys – 1,600-3,200 calories

23. **How many calories should I eat per day to lose weight?The number of calories you should eat per day to lose weight depends on various factors such as your current weight, height, age, gender, activity level, and weight loss goals. A safe and sustainable rate of weight loss is generally considered to be around 0.5kg to 1kg (1-2 pounds) per week.

To estimate your calorie intake for weight loss, you can start by determining your daily calorie needs for weight maintenance and then creating a calorie deficit. A general approach is to reduce your daily calorie intake by 500-1000 calories below your maintenance level to create a deficit.

However, it is recommended to consult with a healthcare professional or a registered dietitian who can provide personalized advice and help you create a suitable and balanced calorie intake plan for your specific needs and goals. They can consider your individual circumstances and guide you toward a healthy and sustainable weight loss approach.
