Diets
explained – The pros and cons of common diets
There are more diets and styles of eating out there than is imaginable.
Year after year new diets sweep into the market place. I have written
this article to give you a better understanding of how, why and
when diets will or will not work for your body.
Definition of a diet ‘working’
Many
people say that a diet worked for them. What this means varies for
each person. It may be they lost a few pounds or felt more energetic.
My
definition of a diet working is a long term and maintained improvement
in health symptoms with accompanying weight loss (or gain) if needed.
My
viewpoint is losing half a stone to find you have put it on again
6 months later is not a sign of a diet working. Neither is losing
4 pounds but still suffering many negative health traits such as
frequent illness, rashes, digestive pains, low energy etc.
Types
of diets
I have
tried to classify the major diets here but there are endless variations
both within the main ones and the main types of diets. So some of
the information may vary but it should suffice to give you an idea
of what is happening nutritionally.
Atkins Metabolic
typing Healthy eating
Following food cravings
Junk food
diet Average
Western diet Juicing diet Blood
type diet Blood
analysis diet Glycemic index Glycemic
load diet Food combination
Zone diet
Mediterranean
diet South beach diet
Low fat diets Weight
watchers Vegetarian
diet
Metabolic
typing diet
Uses
physical, dietary and psychological traits to classify the body
along fundamental systems. This allows the specific foods and nutrients
to be discovered for that individual person.
Pros
– Accurately determines nutritional requirement and
is specific to your own body chemistry. It allows for individuals
to change nutritional requirements during their lifetime as seen
in the real world. Encompasses a large variation in recommendations
for different people which parallels what is seen in the reality.
Head and shoulders above any other nutrition system and its scientific
basis and results cannot be argued against.
Cons
– Can be complicated and difficult to understand
if following on your own and you need to use a trained advisor to
get a level of analysis powerful enough to create long lasting changes

Atkins
diet
Requires
the person to eat greater amounts of protein through meats and to
use fat liberally. Suggests obtaining carbohydrate intake from vegetables,
seeds, nuts and berries. The overall effect is a high protein, high
fat and low carob diet.
Pros
– Suggests removing grains from the diet which can benefit
most people. It ensures you obtain adequate amounts of fat soluble
vitamins and promotes consuming organic foods and vegetables. Will
work for certain people short term but very few on a long term basis.
Cons
– It does not account for the fact that people vary greatly
and a low carbohydrate intake, especially to this extent, can be
disastrous. It does not separate different forms of meat and vegetables.
It does not allow people to change nutritional needs over their
lifetime
Low
fat diet / Calories restriction
Many
combinations of diet follow this theme, with the main emphasis on
low fat, higher carbohydrates and controlled calories. Founded from
ms-interpreted fat studies in the 1950’s. Forms the basis
of Weight Watchers, Jenny Craig and many more diets.
Pros
– Can work for some extreme metabolic types. Any recommendation
to reduce trans-fats is beneficial.
Cons
– Disastrous for the vast majority of the population as depletes
fat soluble nutrients and increases hunger. It does not allow for
individual variance between people or for changes in nutritional
needs over
your lifetime.
‘Healthy
eating diets’
As
recommended by the government food pyramid and all general healthy
eating guides. It is also incorporated into the popular diet schemes
e.g. Weight Watchers etc
Has
an emphasis on lower fat and higher carbohydrates and obtaining
fruit and Vegetable in good amounts.
Pros
– Any diet with emphasis on increasing vegetable intake will
improve many peoples health. Eating lower fat and higher carbohydrate
will work for some people’s body chemistry.
Cons
– Does not separate out individual differences in food requirements,
meaning such recommendations can be disastrous for many people.
The advice does not cater for changes in nutritional requirements
during your lifetime. Grain consumption is also linked to the majority
of present day health issues and thus would not be good advice,
except for certain people’s body chemistry.
Following
your food cravings
Many
people say their body knows best and thus it is only right to follow
what it wants.
Pros
– Works well if you are very in tune with your body and accurately
following a metabolic typing diet and so would know that you are
obtaining your exact nutritional needs.
Cons
– Food is addictive chemically and emotionally and in 99%
of cases food cravings are confused and nothing to do with nutritional
needs. For example your body will crave a cigarette if you have
a few, but that does not mean it is needed. The more sugar or bread
you eat the more you crave them also. Food cravings also drop back
to your dominant gland and
thus can lead to exhaustion if the stimulating foods are over consumed.
Junk
food diet
Eating
whatever food comes your way and not caring what it is.
Pros
– None
Cons
– Decreased health across the board
Average
western diet
The
average Western diet is somewhere between a healthy eating diet,
a junk food diet and following your foods cravings.
Pros
– Very few benefits
Cons
– Any possible benefits of a ‘healthy eating’
diet are usually off set by the Junk food or reliance on food cravings.
This eating style is much worse for certain body chemistries than
others.
Juicing
diet.
Using
a juicer to make any number of juices and smoothies.
Pros
– Can obtain significant amounts of nutrients if done correctly
Cons
– Normally lacks fat and protein amounts for good health.
Reliance on fruit juice can be troublesome for many people. Does
not account for the different nutritional qualities of fruits and
vegetables, grouping them all together as good. Whether a food is
‘good’ is dependent on your body chemistry.
South
Beach diet
The
book recommends very little in reality but for removal of heavily
processed foods and avoiding certain carbohydrates which stimulate
insulin production. It is a mix of the Atkins diet and the Mediterranean
diet with far less restrictions
Pros
– Recommends reducing processed foods which is of benefit
to anyone as is controlling certain insulin raising foods
Cons
– Doesn't account for individual differences and allows people
too many foods that will be wrong for certain body chemistries.
Sold 5 million copies but also holds the title as the having the
most money spent on the marketing of any diet book.
Blood
type diet
This
bases food recommendations on your blood type which is said to indicate
your genetic needs from our ancestors.
Pros
– Acknowledges the fact we all have different nutritionally
needs and focuses on whole foods.
Cons
– Recommendations have no bearing on the person’s nutritional
needs with the majority of his evidence criticized. Does not account
for actual differences seen in the real world or changes during
your life.
Blood
analysis and diet recommendations
Food
recommendations are based on results from your blood test.
Pros
– Acknowledges the fact we all have different nutritional
needs, and uses analysis to make recommendations.
Cons
– Only uses a blood test to give recommendations. Blood is
just one systemic level within the body. Put simply because you
have high or low levels in the blood does not indicate whether you
have high or low levels in the cells where it is needed.
Food
combination / variation diets
Based
on the fact that different foods secrete different enzymes which
can upset digestion. Advises not combining certain food groups
Pros
– Can help people's digestion if it is already severely weakened.
Cons
– Can be dreadful nutritionally as the body needs protein,
carbs and fat at each meal. Does not address the cause of poor digestion
or identify different nutritional needs between individuals
Zone
diet
Advocates
a diet of 40% protein and 30% carbs and 30% fat.
Pros
– Excellent for a proportion of the population
Cons
– Does not work for the majority of people who's nutritional
requirement varies from the recommendations.
Mediterranean
diet
Based
on what is commonly consumed in the south of Europe. The emphasis
is on consuming unsaturated fats and carbohydrates.
Pros
– Can work well for certain people.
Cons
– Does not account for the variability between different people’s
body chemistry.
Glycemic
index (GI) / glycemic load (GL) diets
Makes
nutritional recommendations based on the ability of the food to
raise or lower insulin within the body (glycemic index/load).
Pros
– Aims to reduce the high glycemic foods which will benefit
almost everyone.
Cons
– GI is only one minor factor amongst other variables and
thus should not be used to determine what to eat. Does not account
for individual differences in food requirements or the other contributions
and factors in nutrition.
Vegetarian
Diet.
Often
touted as healthy and very popular for both ethical and lifestyle
reasons. It advises elimination of some or all animals produce.
Pros
– Can work well for people suited to a low protein diet.
Cons
– The diet can be disaster for people with normal or high
protein requirements. Also, many vegetarians fail to adequately
replace the meat proteins through using complementary proteins,
e.g. legumes and grains.
