Your metabolism is the rate at which your body burns calories (energy).
From the American College of Sports Medication they found that a female needs a minimum of 1200 calories per day and a male requires a minimum of 1500 calories a day.
If you have too little calories then your metabolism slows down as it is trying to store energy. It does this because it is not sure when you will have your next meal and wants to conserve energy for your basic survival, for example, to keep you heart pumping. This puts a lot of stress on your body.
What happens when you go into this mode?
Some things include:
- Your muscles are broken down for fuel (Fuel for your brain is used only in the form of Glucose which is a form of sugar) which maintains your blood sugar levels.
- Your body is worn down and it thinks it is now starving.
- The long term effect is that your metabolism can slow up to 40% and can take a full year to correct!
What are the long term effects?
- Fatigue, dizziness and lack of concentration
- Could get sick more often
- You may feel moody, depressed, feel irritable.
- There could be hair loss, kidney failure and/or gallstones.
This is not by any means an extensive list but you can get an understanding of the effects.
In conclusion, make sure that you eat enough calories in one day, but keep them in check as it is a fine line between under eating, over eating and eating just the right amount!
