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.
People looking to loose weight may benefit from taking Citrimax supplements.
- Reduces the amount of carbohydrate converted to fat
- Helps to suppress the apetite
- May increase the rate of weight loss
- Can increase serotonin levels
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).
Citrimax appears to exert a positive effect on weight loss although not all studies have been fully conclusive.
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.
