5 Factors that affect metabolism
1Bodycomposition “This is a key factor and you can influence it,” says exercise science lecturer Paul Hough. “The higher your muscle-to-fat ratio, the higher your BMR.”
2GenderMen tend to have a faster metabolism, as they are naturally heavier with more muscle mass, less body fat and denser bones.
3GenesMetabolism may be partly genetically determined (eg: your genes affect your muscle size).
4AgeMetabolism tends to slow with age, because we become less active and have more fat and less lean muscle mass.
5HormonesThese help balance your metabolism. “Metabolic disorders, like underactive thyroid, are fairly rare and they cause symptoms like fatigue and constipation – not just weight gain,” says GP Dr Pixie Mckenna.
