Metabolism Explained
Your metabolism is important in determining how much body fat you burn. Every person's metabolic rate is different, but in theory, raising your metabolic rate by 10% can decrease your body weight by up to 7.5 kilograms! Your metabolic rate comprises of three factors, two of which you have the power to change:
- Resting metabolic rate the amount of energy expended when you are sleeping or sedentary (60 - 70% of the average person's daily energy use)
- Physical activity (20 - 25% of the average person's daily energy use)
- Thermogenesis an increase in your resting metabolic rate in response to stimuli such as food digestion (10% of the average person's daily energy use)
The two factors that you have the power to change are the physical activity (engage in regular exercise) and thermogenesis (eat every 2-3 hours).
Don't Slow Your MetabolismOne of the fastest ways to slow your metabolsim is to 'crash diet', or try fast diets and fasting. When you lose weight quickly, your body responds to perceived starvation by slowing your metabolic rate to conserve energy. Hence when you start eating normally again, your body stores fat because its metabolism has slowed!
Yo-yo dieting has a similar effect. The more weight you lose, regain and lose again; the more muscle tissue you will shed. Unlike fat, muscle tissue is metabolically active.
So by maintaining a healthy metabolism with exercise and regular eating, you'll enjoy a healthy metabolism - and a healthy weight.
