Fasting, or going without food for an extended period of time, has been practiced for centuries. In recent years, it has become increasingly popular as a way to lose weight or ‘cleanse’ the body. But what if there were more to fasting than that? What if fasting could actually help us live longer and healthier lives? Let’s take a closer look at the science behind fasting and see what it has to say.
The Science of Fasting
Fasting is said to have many benefits, including weight loss, improved mental clarity, and decreased inflammation. But does the science support these claims? Let’s take a look at some of the most promising findings.
One study found that rats who fasted two days per week lived up to 83% longer than those who didn’t fast at all! The researchers believe that this is because fasting allows the body to repair itself on a cellular level. When we fast, our cells are able to focus on getting rid of damaged proteins and producing new, healthy ones. This process is thought to be beneficial for long-term health and longevity.
Another study found that fasting may help to prevent Alzheimer’s disease. The study found that when rats fasted for two days, they showed increased levels of a protein called BDNF. This protein is known to protect the brain against cognitive decline and improve memory function. The rats who did not fast showed no such increase in BDNF levels. These findings suggest that fasting could help to keep our brains healthy as we age and decrease our risk of developing Alzheimer’s disease.
The evidence seems to be mounting in favor of fasting as a way to improve our health and longevity. However, more research is needed before we can say definitively whether or not fasting is truly beneficial for humans. In the meantime, if you’re interested in trying out fasting, be sure to talk to your doctor first to make sure it’s safe for you. Who knows? Fasting just might be the key to a long and healthy life!
