In the post about ‘
Basics of food’ we discussed all 3 micro nutrients,
This post we will focus on only one of
them ‘Carbohydrates’
A little recap
- Carbohydrates are made up of Sugar, Fibre and
Starch
- Carbohydrates are broken down by our body to
give us energy
- We all have
both good and bad carbohydrates available to us, making the right choice is
very important
Food as a fuel
For me personally if I look at food as fuel it is easier for me to make the right choices, So most days I will make sure what I eat is something that helps me improve my life either by giving me more energy during the day or by helping me for my workouts but it should not be something that takes away from my day. I am not saying I manage this all the time but I try to.
- Fuel is something that keeps you moving ahead.
- Carbohydrates as fuel should give you the energy to work out and lead
a more active life
- Try this if you don’t believe --> for lunch have a big meal of
burger and French fries, tell me how you feel about half hour after your meal,
do you feel you can think clearly? Or do you feel you a need to nap? Next day for
lunch have a healthy meal with grilled vegetables and meat, now how do you
feel? Do you even need a coffee?? When I was reading about all this I did try it out and trust me I was feeling sleepy during my meal :D
Understanding how the
body works
(As usual this is very basic, no big terms. I have tried to
make it as simple as I could, no information overload)
- Carbohydrates at some point are converted to glucose by our body;
this is usually travels in our blood and is used by our tissues and cells. A
balance needs to be maintained, too much or too little of anything can be bad.
- Body breaks carbohydrates to sugar (chew on your bread for
sometime it becomes sweet) . If you eat the bad carbohydrates the body will break that into sugar very fast,
so in a short time you will have more sugar in your blood. To balance this the
body produces insulin. Insulin will rapidly work to clear you blood sugar levels and usually takes you
back to the state where you started before eating. So you feel tired and eat
again to cope (Did I make it simple?)
How does insulin
balance your blood sugar?
The level of insulin produced depends on how much is needed
to get your body back to a balanced state.So more bad carbohydrate will lead to more sugar in your blood and that will lead to more insulin produced.
To balance the blood sugar level insulin does two things :
1. Forces excess sugar to your muscles :
Muscles have insulin receptors these decide keep track of how much insulin is produced by your body to decide how much sugar
should be taken in by your muscles
2. Stops fat burning.
Till the insulin levels are high our body will try to
balance things by using the glucose in our blood stream rather than using any
fuel from stored fat
Bad carbohydrates ---> higher blood sugar levels ---> higher levels of
insulin --> turn causes excess sugar in your muscles
and no fat burn (all this balancing your body is trying to do takes away energy in the long run)
How do I select good carbohydrates?
(Simple answer: a good carbohydrate will take time to break
down)
Higher fibre content is usually considered to be sign of a good carbohydrate
Why?
1. Fibre
is difficult to digest --> the body takes time to break it to sugar --> because the process is slow there is no sudden release of sugar in the blood
flow --> no peaks and valley in blood sugar level
2. Fibre
is difficult to digest it also keeps you full for longer --> you eat less
I would like to point out I'm no fitness
expert these are things I learnt along the way of my weight loss journey by
surfing the Internet and talking to trainer.
