Simple Steps To A Low Glycemic Index Diet
Have you read about this recently? over the last 30 years,
research into food and blood glucose response has completely
changed our carbohydrate classification system.
It has been learned that it is impossible to predict the impact
on blood glucose levels by certain foods, instead people are fed
carbohydrate foods and the response measured.
This response is known as the Glycemic Index (GI), it is a
measure of how quickly carbohydrate foods are digested and
absorbed, and ranks carbohydrate foods according to their impact
on blood sugar (glucose) levels: as indicted by elevated blood
glucose.
Foods with a high GI are absorbed quickly into the blood stream
and cause a rapid rise in blood glucose levels. While foods with
a low GI are broken down more slowly over time and keep blood
glucose levels more stable (Remember that low is slow!).
Some carbohydrate foods will maintain your energy levels for
hours, while some may cause your blood glucose to rise and fall.
Different types of carbohydrate can also affect feelings of
fullness in the stomach and this can influence hunger and your
ability to control your body weight.
Why is the GI important?
When our blood glucose levels are stable we have plenty of
readily available fuel for the brain and muscles. If our blood
glucose levels drop too low (hypoglycaemia) we feel tired, dizzy
and generally unwell. If our blood glucose levels rise too
quickly a rapid drop usually follows this.
Include low glycemic index foods in meals and snacks to slow the
release of glucose into the bloodstream. A low glycemic index
snack a few hours before exercise will help maintain your energy
levels for more effective training.
After high intensity exercise (strength training) a high
glycemic index snack should be consumed within 30 minutes. This
will help to replace energy and start the recovery process.
Low-GI foods take longer to digest and help delay hunger pangs
that little bit more and thus promote weight loss. So please
choose your carbs carefully as this will lower your insulin
levels and burn more fat. The secret is to swap high GI foods
with low GI foods.
Steps to a low GI diet
· Start with a healthy, well balanced and varied diet based on a
good nutrition program. The diet should be low in fats, moderate
in carbohydrate and protein. The program should be high in fibre
and contain a varied amount of foods to provide the required
amount of vitamins and minerals.
· Look at the type of carbohydrates that you consume during the
day. Look at the carbs that you eat the most, as these will have
the most dramatic impact on your diet.
Try to change the carbs you eat the most with at least one low
GI one. (Replace potato with sweet potato, use noodles instead
of rice) By substituting half of your daily carbohydrate from
high GI to low GI will result in an overall reduction in the GI
of your diet.
Reducing the GI in your diet reduces your insulin levels and
increases the fat burning apparatus in your body. Try to reduce
the high GI's in
your diet by substituting them with low GI's.
Regular consumption of low GI foods increases the feelings of
fullness and satisfaction and so prevents weight gain. Try
taking in six small meals a day of healthy low fat low GI foods
to prevent overeating at meal times and control appetite.
Remember, that it is also important to look at the calories in
food to. Rice and bread might be low in fat but when your body
is burning the carbohydrates in these foods it doesn't burn as
much fat.
So if you are on a low fat diet, you wont lose as much weight if
your calories are still high.
Have a look at the table below for the different GI food ratings.
Low GI (<50) Medium GI (50-70) High GI (70>) Grapefruit (26)
Pineapple (66) Cornflakes (80) Baked Beans (15) Raisins (64)
W/M Bread (72) Lentils (29) Sweet corn (59) Brown Rice (80)
Peanuts (13) Potato Chips (51) Carrots (92) Soy Beans (15 All
bran (51) Baked Potato (98)
Compare these two menus and try to adjust your diet accordingly.
High GI Menu
Breakfast: 40 Grams of cornflakes with milk. Two slices of whole
meal toast with margarine and jam.
Snack: Two sweet biscuits with a white coffee.
Lunch: Ham and salad whole meal Roll with an apple.
Snack: Four crackers with cottage cheese and chives
Main Meal: Serving of Roast chicken with a large baked potato
and peas. Small piece of cake.
Low GI Menu
Breakfast: 40 Grams of bran with low fat milk. Two slices of low
GI toast (Try Burgen) with margarine and jam.
Snack: Two oatmeal biscuits with a coffee (Low fat milk).
Lunch: Ham and salad Roll (Low GI bread). Soft-serve vanilla
yoghurt with toasted muesli sprinkled on top.
Snack: Two bananas.
Main Meal: Serving of Roast chicken with a small baked potato
and peas. Two scoops of low fat ice cream with half a cup of
canned peaches.
Chicken, beef, fish, eggs, nuts, and avocados contain very
little or no carbohydrates. These foods if eaten by themselves
will not have much effect on your glucose levels and are very
low GI.
Alcoholic beverages especially wine are also low GI so can be
included in your diet but remember to count them in your daily
caloric intake.
In conclusion low GI foods are ideal for losing weight due to
the slow absorption from the stomach. Low GI foods
