Do you want to stop getting fat? Start looking at Glycemic Index



Glycemic Index measures how fast a given food raises your blood sugar level. However the amount of food eaten also matters. Just because a food is low in GI does not mean to say one can eat too much. If the food is high in GI one should eat smaller amounts.

Rice is a common part of Indian cooking.Rice can have moderate to high GI. There are two types of starch; Amylose and Amylopectin. Long grain rice has 22 percent Amylose and 78 Amylopectin while medium/short grain rice has 18 percent Amylose and 82 percent Amylopectin. Relatively higher the Amylopectin, stickier is the texture. Cooking, makes starch to be gelatinized so that human body can digest it and converts it into simple sugar. The important factor is the ratio of Amylose to Amylopectin. Higher the Amylose, lower the GI. So, the long grain rice have lower GI than short grain rice. The bran in brown rice makes lowers the GI further. This makes the Brown Basmati Rice to have lower GI among most of the other Rice from India.

Potatoes are another important part of Indian Cuisine. All root vegetables have moderate to high GI. White potatoes have lower nutritional value than the root vegetables that are rich in color.

A glass of juice contains about 5 table spoons of sugar. Eat fruit instead
All coka colas, fantas, pepsi energy juices have high levels of sugar and caffeine.

Click on any cell and use up and down key on the keyboard to move cells.

Energy in = Energy out = No weight loss
Less energy in = more energy out = weight loss

1 calorie= 1 kilocalorie = 4.18 joules

Walking for 20 mins:
Calories burnt per minute = 5 Kcal
Total calories burnt = 100 Kcal
Percentage of calories burnt from fat = 80% = 80 Kcal
Percentage of calories burnt from carbohydrate = 20% = 20 Kcal

Jogging for 20 mins:
Calories burnt per minute = 10 Kcal
Total calories burnt = 200 Kcal
Percentage of calories burnt from fat = 50% = 100 Kcal
Percentage of calories burnt from carbohydrate = 50% = 100 Kcal


There are 3,500 calories in a pound, so in order to lose one pound per week
you need to decrease calorie intake by 3500 calories. This equates to 500 calories a day.

A 70kg female 25 year old 5.5 feet tall needs about 2250 calories for normal weight maintainance
A 70 kg male 25 year old 5.10 feet tall needs about 2400 calories for normal weight maintainance

10-15% of the calories need to come from protein (see protein requirement table below)

Do you want to stop getting fat? Start looking at foods you eat

Food Glycemic Index ( From Indiacurry.com)


Are you an diabetic? Do you have high blood pressure and high cholesterol issues? Then read this.

Diabetis is not about blood having more sugar. It is about body not being able to digest sugar at the rate it needs to.

Diabetics should follow low/moderate GI food diet. Look at the oils list also.

Barley and Oates are low in GI. They also have beta glucan which will help to reduce cholesterol.

Glycemic Index ( GI) measures how fast a given food raises your blood sugar level
This is important while creating a diet for diabetics and women with PCOS.
However, GI also plays an important role for the people seeking to lose weight.
We will use Glucose as reference with an value of 100,
GI for other Carbs is a relative value to glucose.
The numbers given are compiled from many different sources available in public domain.
These numbers will be close, but not identical to any one given study.
The GI also varies on the ripeness cooking time and cooking methods employed.
Leafy vegetables have low GI and are not included.

Low GI = eat more proportion
Medium GI =eat moderately
High GI = eat occassionally in low quantity

Rice

Rice is a common part of Indian Cuisine and deserves a better understanding.
Rice can have moderate to high GI.
There are two types of starch; Amylose and Amylopectin.
Long grain rice has 22 percent Amylose and 78 Amylopectin
Medium/short grain rice has 18 percent Amylose and 82 percent Amylopectin.
Relatively higher the Amylopectin, stickier is the texture.
Cooking, makes starch to be gelatinized so that human body can digest it and converts it into simple sugar. The important factor is the ratio of Amylose to Amylopectin.
Higher the Amylose, lower the GI. So, the long grain rice have lower GI than short grain rice.
The bran in brown rice makes lowers the GI further.
This makes the Brown Basmati Rice to have lower GI among most of the other Rice from India.


Potatoes

Potatoes are another important part of Indian Cuisine.
All root vegetables have moderate to high GI.
White potatoes have lower nutritional value than the root vegetables that are rich in color.

Sweet potatoes are low in GI and high in fibre. Substitute potatoes with sweet potatoes.

Watermelon is high in GI. Cherry is low in GI.

Do you want to stop getting fat? Start looking at oils first!

Use oils with either Mono unsaturated or poly unsaturated fats. Do not use the oils high in saturated fats and those which have trans fats. Dont go crazy with oils. One tea spoon of oil is approximately 120 calories. To burn 120 calories you need to walk atleast 1 kilometer in a brisk manner. Do you want to stop getting fat? Then start with oils.
