Review of Citrimax (HCA)
What is Citrimax (HCA)? Hydroxycitric acid (HCA), also known as
CitriMax, is a natural extract from the dried rind of the Garcinia Cambogia
Fruit. The dried fruit rind is traditionally used in South Eastern Asia to make
food more filling and satisfying. A number of studies have demonstrated HCA to
be an effective and safe weight loss product. Citrimax doesn’t have the negative
side effects associated with, thermogenic weight loss supplements.
Who Should Consider Taking Citrimax (HCA) supplements? People looking to loose weight may benefit
from taking Citrimax supplements.
Summary of Citrimax's (HCA) Phyiological Effects:
- Reduces the amount of carbohydrate converted to fat
-
Helps to suppress the apetite
-
May increase the rate of weight loss
-
Can increase serotonin levels
Citrimax (HCA) Research HCA works in two distinct ways: Firstly,
HCA reduces the amount of carbohydrate that is converted to bodyfat. It does
this by blocking a key enzyme (ATP-citrate lyase) which otherwise acts as a key
building block for fat synthesis (Shara et al., 2003). Because Citrimax reduces the
amount of carbohydrate being converted to fat, more carbohydrate will be stored
as glycogen within your muscles. This will mean you are more likely to have
increased glycogen storage. Secondly,
HCA is known to have an appetite suppressing effect (Roy et al., 2004). As well
as these two weight loss mechanisms, Citrimax also increase the rate of fat oxidation
– metabolism of fats (Shara et al., 2003).
The reason for the
appetite suppression may be partly attributed to the raised glycogen stores.
When glycogen stores are full, the glucoreceptors in the liver, send chemical
signals to your brain which then thinks you are full and thus suppresses your
appetite.
Research has
demonstrated that Citrimax supplementation increases the rate at which weight is lost
and also has this appetite suppressing effect (Preuss et al., 2004; Roy et al.,
2004).
One of the main reasons
that HCA may suppress appetite is through its ability to increase the level of
the important neuro-transmitter serotonin (Ohia et al., 1998; Preuss et al.,
2004). Serotonin has a profound effect on mood, with low levels of serotonin
associated with depression. The rise in serotonin levels is an important factor
for dieters as most people on diets generally suffer with low moods due to the
low intake of food and when serotonin levels are low they you are much more
likely to crave sugary foods. Therefore, the increased serotonin levels will
have a positive effect for dieters, by decreasing appetite, and decreasing
cravings for sugary foods.
A number of studies have
demonstrated HCA’s to lead to reductions in body mass and body fat (Shara et
al., 2003; Roy et al., 2004; Preuss et al., 2004). However, it should be noted
that some studies have failed to see a positive effect with Citrimax supplementation
(Heymsfield et al., 1998; Pittler and Ernst, 2004).
Is Citrimax (HCA) effective? Citrimax appears to exert a positive effect on weight loss although not all studies have been fully conclusive.
How to take Citrimax (HCA)? It is generally recommended that for
weight loss you should consume 250mg of HCA, 1-3 times a day. HCA should be
taken before meals (45-60 minutes before meals) so that the active ingredients
are in your system when you consume your food.
