The more research that is conducted about the weight loss benefits of grapefruit, the more confirmation we get about how effective it really is. It is believed that the weight loss benefits of grapefruit revolve around one of the enzymes it has that is involved in the chemical process which generated energy.
When this enzyme gets activated, it influences the body’s natural processes that turn the sugars we eat in to the energy that our cells use, known as ATP. This influences weight loss by increasing metabolism, and this release of energy during exercise can also help improve muscle endurance as well.
Studies conducted on animals as well show that grapefruit juice alone can be more effective than traditional weight loss prescription drugs. One study in particular compared the use of grapefruit juice to a no longer used drug called sibutramine, which was used to lose weight.
Grapefruit juice was not only found to be more effective than sibutramine in reducing weight, but also didn’t come with the side effects of heart attack and stroke.
Although grapefruit juice has been proven to be effective in losing weight, fresh grapefruit is the best source to get these benefits. Just half a glass of grapefruit juice was seen to help reduce weight by improving insulin resistance.
Insulin resistance is a major cause of type 2 diabetes, which is a major contributor to weight gain and obesity itself. Eating grapefruits or drinking juice is definitely an effective way to lose weight.
What Other Health Benefits Do Grapefruits Provide?
Grapefruit contains many different beneficial chemical compounds, however when it comes to cancer phytochemicals naringenin and limonin have shown to be especially effective in reducing the growth of many different cancer types.
These include colon, stomach, breast, mouth, skin and lung cancers among others. Not only did the growth of cancer stop, but the cancer cells themselves seemed to self correct.
In a typical cell, there is essentially an internal timer that tells it when it to blow up, or undergo apoptosis, cellular suicide. This is done because if the cell continues to grow after a certain period of time it is more prone to mutations and thus the formation of cancer.
Cancer cells do not have this mechanism, which allows them to continually grow unchecked. It is believed that grapefruit has the potential to “turn back on” this mechanism allowing the cells to “die” at the proper time in their lives.
In addition to these phytochemicals, grapefruit contains other powerful antioxidants like vitamin C which help to neutralize free radicals. Free radicals are another cause of cancer and antioxidants help to prevent the body against these carcinogens.
2-Grapefruit Can Boost Immunity
As mention prior, grapefruit is a great source of vitamin C. Vitamin C is not only important in fighting cancer, but in boosting immunity overall.
Time and time again studies have been conducted on the effectiveness of vitamin C in its ability to improve immune function. The vast majority of the studies conclude that Vitamin C helps the immune system, and that not getting enough can compromise the immune system to where it is more vulnerable to sickness and disease.
3-Grapefruit Can Help to Fight Aging and Improves Skin Appearance
Vitamin C also helps to build collagen, which is what makes our skin look nice and retains its elasticity. Basically vitamin C helps to prevent wrinkling from aging and sun damage.
Pink grapefruit, one of the most common varieties also contains beta-carotene which helps to slow down aging and maintains skin health as well. Beta-carotene is also effective in treating hyperpigmentation, or the darkening of some parts of the skin as a result of over production of melanin.
If you have oily skin, grapefruit contains an ingredient called salicylic acid which is known for its ability to clean out pores and fight bacteria associated with acne breakouts.
Concerns About the Consumption of Grapefruit
Grapefruits can be really healthy foods that can improve your overall health, however there are some things you should be aware of.
Grapefruits contain compounds known as furanocoumarins which block certain enzymes in the body. Many of these enzymes that are blocked are used to break down and metabolize certain medications, so if you are on a prescription check with your doctor before you start consuming grapefruit.
Grapefruit also has shown to slow the elimination of caffeine from the body, so if you drink coffee or tea regularly it is something to keep in mind.
