With all the media coverage of the latest diets the super-skinny
celebrities are using, its not surprising that so many people fall in to the
trap of diet-hopping, with an outcome of heightened mental frustration as
opposed to long-term weight loss success.
People get drawn into new 'fads', with the promise of 'quick',
'instant', 'guaranteed' results, but these are often centred around drastically
reduced calorie intake as opposed to sensible, healthy eating.
These diets cause short-term
water and lean muscle tissue loss, giving the illusion of effective weight
loss. Lean muscle tissue is metabolically active, meaning that the more lean
muscle tissue an individual has, the more calories are burned. The reduction in
lean muscle tissue reduces the body's ability to burn fat.
This is where the 'yo-yo' term
becomes relevant because, once the body adjusts the metabolism to the reduced
calorie intake or the 'normal' calorie intake is resumed, any initial weight
loss is often regained. It is also common for individuals to end up gaining
more weight then prior to the diet because of the 'famine strategies' employed
by the body during the restrictive period.
Starvation strategies - kick in with low calorie diets and result in
increased levels of lipoprotein lipase in the body (an enzyme responsible for
transferring fat into the bodies fat stores), so the body starts storing
calories away as fat as protection against further 'starvation'.
The psychological frustration caused by what seems like a backward step
often drives individuals to try another drastic 'solution' to turn things
around and achieve results quickly. The result is a vicious cycle of yo-yo
dieting!
So, apart from the obvious flaw of providing only a temporary solution,
here are some of the real dangers of yo-yo dieting:
·
Mental/emotional frustration - which vents itself in mood swings, low
self- esteem and disordered eating. Numerous studies link chronic dieting with
feelings of depression and increased stress, anger and bingeing.
·
A higher risk of heart disease and some cancers then individuals whose
weight remains stable if even overweight. This is due to reduced levels of
specialised immune system cells.
·
Long-term fatigue of an individual's metabolic rate.
·
Increased risk of osteoporosis, fractures and broken bones - due to the
nutrient deficiencies common in calorie restricted regimes.
·
Loss of muscular strength and endurance and loss of co-ordination.
·
Fainting, weakness and slowed heart rates.
·
Issues with memory as the stress and anxiety about food and weight can
actually consume a significant portion of a dieters working memory.
·
Dieting can in some cases lead to an eating disorder as a result of body
dissatisfaction and constant concern with bodyweight and shape, fat grams and
calories.
The solution to permanent weight loss: consume enough energy to burn fat
and eat the right foods to maintain lean muscle tissue. A sensible, balanced
diet and moderate exercise gives real, long-term results.
