A Cleansing or De-tox
Method, Not a Weight Loss Method
Fasting has been recommended for years to cleanse or de-tox the body.
Some fasts or de-tox diets allow only water. Others permit fruit/vegetable
juices and in due course some solid food.
Appraisal of Fasting
A very short term fast (e.g. 24 hours) may indeed help to cleanse the
body of toxins. However, it is not a suitable weight loss method, because
fasting deprives your body of nutrients and does nothing to help you modify
your dietary habits. In fact, if undertaken for several days, a fast can
lead to a slow down in your metabolism and an increase in food-cravings.
This can lead to weight gain when the fast is over.
The Problem of Fasting
The human body thinks a fast is a famine. So to save energy and preserve
fat-stores, it starts to burn calories more slowly. As stated above, this
can lead to weight gain when the fasting finishes.
Other Side-effects of Fasting
Unless the fast is very short term, you can end up with low energy, weakness
and lightheadedness, without any significant weight loss. Furthermore,
the absence of carbohydrates may lead to ketosis - a dangerous build up
of ketones that pressurizes the kidneys. This is unhealthy and can be
Other symptoms may include:
- Dizziness and faintness
- Bad breath (from ketosis)
Fasting May Cause Loss of Muscle Tissue
A prolonged fast, especially if accompanied by vigorous activity, may
cause the loss of lean muscle tissue, including muscle loss from vital
organs like the heart. This is very dangerous.
A short fast every few months in order to help cleanse your body, may
be beneficial. But using fasting as a way to lose weight is unhealthy
and may be dangerous.
A Note about Healthy Weight Control
Fad diets, unbalanced diets, diet pills, diet supplements, weight loss
surgery and other short term weight loss methods are not recommended for
permanent weight control. The best way to lose excess fat and maintain
a healthy weight in the long term is to follow a balanced calorie-controlled
diet (that improves your eating habits) and take regular aerobic exercise.
