the most frequently asked question when losing weight is 'why does weight loss slow
average woman needs about 1800 – 2000 Calories a day to fuel daily activities including the task of
keeping the body warm and internalfunctions. An average man needs about 2000 - 2500
Calories a day to fuel daily activities including the task of keeping the body warm and internal
is caused by consuming more Calories than the body needs. By consuming 100 Calories a day more than
is required, the body will store the extra energy and it will result in about a 10-pound weight
gain over the course of one year. (I.e. 100 x 365 = 36, 500 with one pound of fat equalling 3,500
Calories. The definition
of obese is BMI >30. Height in metres squared, divided into weight in kilos
To become 3 stone
overweight, someone has to have consumed 147,000 more Calories than they needed. To remain 3
stone overweight they have to eat 300 – 350 Calories a day more than they
To lose weight
you have to consume fewer Calories than your body needs. When you restrict intake, the first
fuel the body uses is glycogen and contains 4 Calories a gram (1800 Calories a pound).
We have about 1lb of glycogen stored in the liver and muscles. Glycogen is stored with about
5 times its own weight of water.
To lose the
first 7 pounds, which is glycogen and water, you have to cut back 1800 – 2000 Calories. If
you cut back by 300 Calories a day it will take 7 – 10 days to lose the glycogen stores; the
weight loss will be about 7 pounds
The next fuel is
body fat and contains 9 Calories a gram (3500 Calories a pound). To lose the next 7 pounds,
which is body fat, you have to cut back 3500 x 7 which is 24,500 Calories. If you carry on
cutting back by 300 Calories a day it will take 7 – 10 days to lose another pound. It will
take 7- 10 weeks to lose the next 7 pounds.
This is one
reason why people lose heart and give up. The initial weight loss is not sustained, not
because they are doing anything ‘wrong’, but because they are now burning fat and it is a
very dense energy rich source of fuel.
