Crestor is the brand name of Rosuvastatin, a synthetic lipid-lowering drug. It is considered the most effective drug that lowers bad cholesterol (LDL-C), however, its effects on belly fat and body weight are not fully known.
Obesity is one of the components of metabolic syndrome. In fact, reducing weight is associated with a significant reduction in the incidence of diabetes, hypertension, dyslipidemias, and heart diseases.
Statins and Belly Fat:
The effect of statins on body weight is not very clear. It is generally assumed that people who are put on a statin are also advised to consume fewer calories and fats.
Data from a US study evaluated the trends of caloric intake and statins use. It was found that from 2005 onwards, the difference in fat and caloric intake was minimal in statin-users and statin-nonusers.
It was also found that the weight gain was greater in people who were on statins. Furthermore, the weight gain was disproportionate to the extra calories consumed per day.
Thus, in conclusion, statins use was associated with weight gain and more belly fat [Ref].
Crestor and Belly Fat:
Crestor (Rosuvastatin) is a high potency statin that removes the bad cholesterol from our blood. It acts by inhibiting the process of cholesterol synthesis in the liver by inhibiting the enzyme HMG-CoA reductase.
When the LDL cholesterol, the bad cholesterol, levels drop inside the liver cells, the cells make more receptors that catch LDL from the blood and bring them inside the liver cells.
When more receptors are present, more LDL-C is internalized from the circulation. Hence, less cholesterol (LDL-C) is available to be deposited in the blood vessels.
Thereby reducing the risk of atherosclerotic coronary artery diseases.
Low blood cholesterol is not synonymous with less belly fat!
Crestor removes the bad cholesterol from the blood, however, it has no effect on the fat that has been deposited outside the blood vessels.
Statins are not fat-burning drugs. They do not make you lose weight. On the other hand, weight loss pills may make you lose weight but they do not lower your cholesterol levels in the blood.
How does Crestor affect your Belly Fat?
There are two types of fats in our body: Subcutanoues fats and Visceral Fats.
Subcutaneous fat is mostly present in the following areas of our body:
- Hips and Thighs
Visceral fat is also called internal fat that surrounds our organs. Most people with large bellies have large amounts of visceral fats too, however, thin and lean people can also have large amounts of visceral fats.
The greater the visceral fat is, the greater the likelihood of a person developing cardiovascular diseases.
One study evaluated the effects of Crestor on subcutaneous and liver fats in rats. It was found that Crestor significantly increased subcutaneous adipose tissue and worsened insulin resistance [Ref].
Another study evaluated the effects of Crestor on weight gain, lipid profile, and insulin resistance in a mice model. Mice were given a high-fat meal for 8 weeks. One group was given Rosuvastatin 20 mg/kg for 8 weeks while a placebo medicine was given to the other group.
It was noted that mice treated with Crestor had a significant reduction in body weight, improvement in lipid profile, and atherogenic index. Rosuvastatin induced satiety and its effect on the hypothalamus was thought to cause weight loss.
Crestor also reduced the harmful effects of fatty acids and leptin resistance. Unlike, other statins, Crestor, when administered in high doses, was associated with an improvement in insulin resistance and pancreatic Beta-cell function [Ref].
Statins, and especially high potency statins like Crestor (Rosuvastatin), are used to lower your blood cholesterol levels.
Most people who are put on a statin are also advised to consume fewer calories and exercise regularly which might influence the change in their body weight and belly fat.
However, statins, including Crestor, have not been clearly associated with changes in body weight and belly fat.
