  • Diet and metabolic rate
    • A balanced diet does a lot to keep you healthy
      • Carbohydrates- to release energy
      • Fats- to keep warm and release energy
      • Protein- for growth, cell repair and cell replacement
      • Fibre- to keep everything moving smoothly through your digestive system
      • Vitamins and minerals- to keep your skin, bones, blood and everything else generally healthy
    • Peoples energy needs
      • You need energy to fuel the chemical reactions in your body that keep you alive
        • These reactions are called metabolism
          • The speed at which they occur is your metabolic rate
            • Physically bigger people are likely to have a higher metabolic rate than smaller people
              • The bigger you are, the more energy your body needs to be supplied with (because you have more cells)
            • Men tend to have a slightly higher rate than women
            • Regular exercise can boost your resting metabolic rate because it builds muscle
              • When you exercise your heart rate increases
