A healthy eating (or refusing to eat) movement has been linked to many health benefits, however, it’s more complex than it seems.

When you hear “fasting,” you probably think of fun diets, and you may feel “hungry.” But, a growing amount of research suggests that incorporating very low-calorie days in your daily routine could be beneficial to your well-being (more on this later). Find out everything you should learn about intermittent fasting, before taking a break from lunch and let your stomach growl.

What exactly is intermittent fasting (IF) and how do you use it?

In its simplest form the term intermittent fasting (IF) is the practice of strategically starving yourself. It is the aim of alternating periods of eating normally with periods of fasting that is, you significantly decrease your calories intake or you don’t eat. Certain people fast for a couple of hours or more, while some may go on a be fasting for the whole day.

Fasting isn’t a universally-fitting solution.

IF could mean different things based on the person you are asking. It is possible that the 5:2 method, that entails cutting calories for two consecutive days per week, and eating calorie-free for the rest of 5 days is among of the most widely-known fasting methods. (In an Men’s Journal piece last year, Jimmy Kimmel hailed the 5:2 diet as a key factor in his weight loss.)

Some may even fast regularly and eat for an exact time. Mark Mattson, a neurologist at the National Institute on Aging in Maryland who has conducted a significant research on the subject and told The New York Times that he isn’t eating breakfast or lunch the majority of days. He also consumes all his calories in a six-hour time frame that starts after lunch. Hugh Jackman also claimed that for him to stay fit for the role in the race, he fasted 16 hours, and ate within the timeframe of 8 hours.

Fasting is a healthy way to eat that has benefits that go beyond weight loss.

Based on various studies, fasting can improve overall health and prolong lifespan due to its effects on hormone and cell function. Fasting for a period of time, for instance has been associated with lower risk of diabetes, heart disease, cancer and the aging process in a study that was recently released in Cell Metabolism.

Why does fasting has such a positive effect on well-being? In the time of fasting the cells die and stem cells get activated to trigger a regenerative process that leads to the growth of young, new cells according to researcher Valter Longo PhD. He said, “It sounds too wonderful to be true, but it isn’t.”

Intermittent fasting was demonstrated in various studies to reduce the level of low density lipoprotein (LDL) which is also known as “bad” cholesterol, as also inflammation. Furthermore, IF may help to lower insulin resistance, which can help to maintain blood sugar levels.

The focus is usually on the time to eat, instead of what food to eat.

There isn’t an all-inclusive fasting regime; instead the fasting regimens can be extensively customized. In the period of fasting certain people are allowed to consume black coffee or green juice, while some restrict themselves on calories to 500.

On days of fasting such as this, Kimmel told Men’s Journal that his “meals” may include peanut butter and apple and hard-boiled egg whites or even a cup of oatmeal. “I’m a glutton the rest of the week–pizza, spaghetti, and steak,” Kimmel said to the magazine.

However, according to Libby Mills, RD, who is a representative of the Academy of Nutrition and Dietetics, Kimmel illustrates one of the issues when it comes to fasting diets. “Nutrition isn’t usually the main focus,” states the writer “she clarifies. “The majority of the time, it’s all about the calories.”

It may help in reducing weight however it might not be suitable for everyone.

Hey, it did help Jimmy Kimmel and Hugh Jackman to get fit. While fasting can help in weight loss, Mills cautions that it isn’t a method that’s sustainable or feasible for all.

“It’s not something I personally suggest in my practise since I believe there are many other strategies to accelerate weight reduction without going cold turkey with eating,” she states. “Instead, concentrate on eating more fruits and vegetables. That way, you can concentrate on choosing appropriate calories and incorporating nutrients. It’s a step forward from the all-or-nothing mentality.”

Also, you don’t know what the effects of a diet that restricts calories will have on you emotionally and physically Mills claims. Mills says “You may not know how your body will react to, instance, low blood sugar.” “Or, other individuals find that fasting is easy until around 3 p.m., when cravings kick in and you end up eating stuff you wouldn’t ordinarily consume.”

What’s the final word? “You have to think about how limitation affects you personally,” she says.

Before you begin an eating plan that is fasting, consult your physician.

Before you attempt IF it, be thinking about your character as well as your overall health.

“The doctor should be engaged whether you’re thinking about attempting a fasting regimen for prevention or as a therapy,” Longo says. “Many things must be evaluated, such as your present diet or if you have diabetes or a metabolic problem,” according to the doctor.

It’s also important to speak to a nutrition or health specialist to determine what program is appropriate for your particular lifestyle.

Longo writes, “An athlete with a perfect pescatarian diet may profit from merely fasting twice a year.” “However, someone with high cholesterol and considerable belly fat could benefit more from practising it on a daily basis.”

The long-term effects of fasting aren’t yet fully understood. A majority of research about the subject was conducted over a relatively short amount of time. Although scientists have conducted some human-based research and continue to carry out research, a lot of the information we have today is derived from data collected by animals.

Mills believes that more research is needed. If you’re considering adding fasting to your diet, consult an expert in health to create an action plan to ensure that you’re eating the right foods for fasting as well as other days of fasting to ensure your health.
