      • Fibre- digestive system smooth
    • Metabolism
      • Energy to fuel Chemical Reactions
      • Muscle needs more tissue than fatty tissue
      • Bigger ppl= higher MR
      • Men = higher MR
    • Eating too much
      • Excess Carb. and Fats= obesity

      • Hormonal Problems
      • Arthritis, type 2 diabetes, high blood pressure + heart disease
