It is true that many people that start a
low fat or a low calorie diet will often end up heavier than their
pre-diet weight. Though they do lose weight with these diets, what hits
them is the regain that occurs months later. Some of what contribute to
this regain is a slowed metabolism and an increased sense of hunger
among others. The research quoted in this video – from Gary
Taubes book "Good Calories Bad Calories" is
testimony to this.
I like the way the presenter is referring to low fat and low calorie
diets as semi-starvation diets. This is because most people equate
dieting to starving themselves for a while. However I do need to note
some misinformation that is would be passed on in this video; and that
is the concept of "unlimited calories". Calorie counting and calorie counters may
not be many dieters favorite but they form the fundamenatlas of losing
weight.
First you need to understand that the science of losing weight depends
on a calorie deficit - however you achieve it. This means that to lose
weight you have to consume fewer calories than you need or spend more
calories than you have eaten. This can be achieved by, one; reducing
the amounts of calories you eat, two; increasing calorie expenditure
e.g. through exercising
or three; using both techniques.

is
particularly effective because it uses both exercises and diets to
achieve healthy weight loss. And that’s why it able to lead
to huge loses in weight in a short time.
The concept of unlimited calories as forwarded at the end of this video
can then be confusing to a lay man. It is the same arguments forwarded
in low carb diets like Atkins.
It is usually presented as "you can eat all you want (unlimited
calories) of a certain
food group". However it has been proven that even the results
you get with diets like Atkins are because of a lower calorie intake
(see the video here).
Here is the explanation; the diet recommended in the video as well as
diets like atkins contain high amounts of proteins –
particularly meats. And though beef and tuna do have equivalent
calories to carbohydrates, they do not result to the same increase in
sugar levels in the blood as carbs do. It is the spike of blood sugar
in the body that results to the sugar being converted into body fat
using insulin.
To make matters better for proteins, the body does not store proteins
in the body. Once you eat your meat, it is broken down into its
components (amino acids). The body picks the amino acids it need to use
in the body, for repairing tissues or forming new muscles for example,
and then excretes the rest. Your body always prefers carbohydrates as a
source of energy. And though if put in dire need of energy, it can use
proteins, it usually does not.
Even when using amino acids (proteins) for energy the biological path
used to create glucose from protein is so elaborate and produces just
enough glucose that it does not cause the spike in blood sugar that
demands the excess glucose to be stored as body fat.
So unlike carbohydrates that are absorbed as glucose and when in excess
is stored as body fat, proteins do not follow the same biochemical
pathway. So evidently, you will seem to be eating unlimited calories,
but in reality your body does not translate it as such.
I’m sure a high protein diet then looks very attractive right
about now. However, experts are very wary of these diets because you
body
will need to flush out all that excess proteins. Remember you body does
not store amino acids (proteins) as it does with carbs (body fat).
Experts note that this could end up straining your kidneys and causing
other complications.
This kind of scientific understanding of dieting is the reason I highly
recommend

.
This is because they have a team of certified experts e.g.
dieticians, medical doctors etc, that customize your weight loss
program. Such a program avoids the risks of a strict high protein diets
as well as the semi-starvation diets like most low calories diets.
Though some of these diets may work for some people, the problem is
usually the long term health as well as weight regain that most often
happens once you go back to normal eating. Consider GHF below, they
currently have a great offer.
