May Play A Role In Cancer Treatment And Prevention

How Intermittent Fasting Boosts Immunity | Jason Fung

This potential benefit is still a bit up in the air. Animal models have shown that periodic fasting may help protect normal cells from the toxic effects of chemotherapy drugs while sensitizing cancer cells to the treatment .

When it comes to human trials, the data is still inconclusive. Weight control and reduced inflammation in the body could reduce the development of cancer, but further research is needed to understand the role fasting may play in cancer treatment .

How Does Intermittent Fasting Work

There are several different ways to do intermittent fasting, but they are all based on choosing regular time periods to eat and fast. For instance, you might try eating only during an eight-hour period each day and fast for the remainder. Or you might choose to eat only one meal a day two days a week. There are many different intermittent fasting schedules.

Mattson says that after hours without food, the body exhausts its sugar stores and starts burning fat. He refers to this as metabolic switching.

Intermittent fasting contrasts with the normal eating pattern for most Americans, who eat throughout their waking hours, Mattson says. If someone is eating three meals a day, plus snacks, and theyre not exercising, then every time they eat, theyre running on those calories and not burning their fat stores.

Intermittent fasting works by prolonging the period when your body has burned through the calories consumed during your last meal and begins burning fat.

But 12 Hour Fasting May Not Work

If you are anything like I was with hormone issues, gut imbalances, sleep issue, a liver needing detoxed or any vitamin deficiencies, 12-hour Intermittent Fasting may not work for you.

I always suggest to anyone interested in implementing a 12-hour Intermittent Fasting schedule, to get their bloodwork and labs. This helps to ensure your body is in optimal shape to change your diet.

Consider the following labs: hormones along with vitamins and minerals.

If your lab results show an imbalance, check out a few articles at Clean Cuisine to get you back to optimal health so you can begin taking advantage of all of the 12-hour Intermittent Fasting benefits.

Weight Loss And Weight Management

Fasting for more than 1012 hours pushes the body into the metabolic state of ketosis, where body fat is burned for fuel rather than blood sugar. This helps reduce body weight and the amount of stored fat in the body.

Intermittent fasting also creates much shorter eating periods, making it more difficult to overeat. With fewer hours to actually eat, you are unlikely to eat more than the recommended number of calories each day, creating a calorie deficit that is essential for weight loss.

It may also be useful for people who have tried other kinds of diets with little success. This is because intermittent fasting allows you to continue to eat the things you like but restricts the time you can eat them.

If youre considering using intermittent fasting as a method of weight loss, check out the DoFasting app for tips and tricks on maintaining this diet, as well as recipes that are intermittent fasting-friendly.

How Does The 1: 12 Diet Work

Intermittent fasting relies on the feed-fast cycle. With regular food consumption, the main source of our energy is sugar, but when fasting, the blood sugar levels drop. This drop stimulates our body to utilize its storage of fatty acid as a source of energy . This cycle is known as the feed-fast cycle.

What Happens After Not Eating For 12 Hours

The main benefit of fasting is that your body is forced to look inside for energy rather than using carbohydrates and other nutrients from foods for energy. During the first 12 hours of a fast, your body begins to use stored fats for energy. This is why fasting is such a popular dietary method for those who are looking to lose weight quickly.

Another reason why fasting helps you lose weight quickly is that it reduces your calorie intake, simply because youre not eating. By partaking in fasting you may find it easier to cut back on calories every day. The energy restriction from a 12-hour fast may also benefit your metabolism, helping in weight loss.

How Safe Is Intermittent Fasting

The 12 hour intermittent fasting Keto or Ketogenic diet and other carbohydrate-restricted diets aim to achieve ketosis, which is an accumulation of acidic ketones in the blood. As much as the outcomes are great, ketosis can cause liver, brain, and kidney damage. It is unsafe for individuals with chronic disorders such as diabetes and heart disease. Your blood sugar should also be stable for you to follow this diet plan. Therefore, it is important to discuss with your doctor and seek guidance from a licensed dietitian before beginning 12 hour intermittent fasting.

Restrictive Eating Can Influence Disordered Eating

Any diet that supports skipping meals or restrictive eating can trigger some not-so-great food relationships. Especially when the positive weight loss effects are directly impacted by not eating, or restricting food intake.

This isnât a great mindset to go into fasting with and can lead some people to take intermittent fasting too far, developing disordered eating patterns, or getting caught up in a yo-yo dieting cycle.

Not to mention that not eating enough calories each day to meet your basic needs can lead to nutrient deficiencies, decrease your immunity and create havoc in your body.

Make sure youâre being honest with yourself before trying any kind of fasting practice and consult with your practitioner beforehand as a mindful or intuitive eating approach may be a better option.

Whatever your reason for wanting to intermittent fast, remember to incorporate basic nutrition principles including calorie control and a balanced diet to set yourself up for success.

What Are The Benefits Of Not Being Full All The Time

Regular breaks between eating give our bodies time to carry out valuable housekeeping, according to Dr Collins. After a meal, you absorb the glucose from carbohydrates in food for energy, and either use it immediately or store it for later. In a fasted state, which typically starts 1012 hours after your last meal, the body is depleted of this form of glucose. Then the liver begins to break down stored fat into fatty acids called ketones to use as fuel. This process is known as metabolic switching and is a reason why fasting can lead to weight loss.

But emerging science suggests fasting activates certain chemicals and processes that confer health benefits beyond losing weight. Its also thought to encourage the growth of beneficial gut bacteria that could be good for us in many different ways.

The problem is, most of us are too full for too much of the time to experience these benefits, says Collins. Eating three meals a day plus snacks, as many of us do, means were in a constantly fed state. As a result, our bodies continuously process new intakes of food instead of dealing with fat reserves.

All the things we associate with poor metabolic health and disease risk cardiovascular disease, insulin resistance, diabetes and low energy are essentially a manifestation of fuel mismanagement, he says. Eating in a grazing pattern means youre not able to store, liberate and utilise fuel in the right way.

How To Begin 16 8 Fasting

For people that get hungry first thing in the morning, this 16 8 Fasting schedule may be a bit tough to embrace. My suggestion is to push back the morning window by 30 minutes every day or two until youre comfortable waiting until 12pm to begin your 8 hour eating window.

You can also consider drinking water, coffee and other drinks that have no calories. This does help reduce the feelings of hunger and make it a little easier to transition.

Hours Of Feeding + 12 Hours Of Fasting

How many hours a day should you fast when intermittent fasting?

You have to decide when to start fasting, add 12 hours and then starting feasting. I tend to go with the 9pm 9am fasting period and sometimes, will extend my morning by 1-2 more hours a few times a week.

This helps to keep my body guessing when I am going to feed it, which helps my focus and prolonging the detoxification process.

What Are The Benefits Of Intermittent Fasting

As we mentioned previously, the benefits of intermittent fasting extend beyond weight loss. There is a mound of evidence that points to intermittent fasting providing full-body benefits as well as brain benefits. Here are some of the benefits of intermittent fasting, whether it be 16/8 or 12/12:

  • Lowered risk of type 2 diabetes – Fasting can reduce your insulin resistance, which can help lower blood sugar levels, protecting against type 2 diabetes
  • Reduce oxidative stress and inflammation – Oxidative stress can oftentimes lead to chronic diseases. Fasting can help enhance your bodys resistance to oxidative stress, fighting off inflammation
  • Improved heart health – Intermittent fasting has been shown to improve numerous different risk factors, including blood pressure, total and LDL cholesterol, blood triglycerides, inflammatory markers, and blood sugar levels
  • Prevent cancer – While more research is needed, current research does show that fasting can help prevent cancer
  • Brain health – Fasting can induce bodily functions, such as autophagy, which help reduce oxidative stress, reduce inflammation, and reduce blood sugar levels

When considering starting a fasting diet, you should consider all of these benefits, on top of the weight loss aspect of the diet.

Benefits To Fighting Inflammation

Inflammation is your bodys normal response to containing and fighting infection and repairing tissue damage. But chronic inflammation can occur when this immune response lingers, causing oxidative stress. This is linked to heart disease, Type-2 diabetes, cancer, multiple sclerosis, inflammatory bowel diseases and other conditions.

Intermittent fasting has the potential to manage or prevent chronic inflammation, according to some researchers. A study published in the prestigious New England Journal of Medicine found that in some groups, ketones produced during fasting improve the ability of cells to suppress inflammation and repair damage.

A separate study by a team at Mount Sinai hospital in the US found intermittent fasting reduced the release of pro-inflammatory cells called monocytes, and put them into sleep mode. Given the wide range of diseases caused by chronic inflammation, researchers said there was enormous potential in doing more research into the anti-inflammatory effects of intermittent fasting.

Research is ongoing into whether these benefits stem from the weight loss or the fasting.

Improves Insulin Resistance Which Can Help Diabetes Prevention And Management

Intermittent fasting and weight loss may help reduce fasting blood glucose and improve insulin sensitivity through lowering concentrations of leptin, the hormone produce by fat cells to regulate hunger, and increasing adiponectin, a hormone that plays a role in glucose and lipid metabolism.

In some studies where fasting was used as a weight-loss intervention and strategy for maintaining a healthy weight, people who intermittently fast had lower levels of blood glucose which happens to be a central goal in the prevention and treatment of diabetes .

These possible benefits may be driven more by reductions in body weight and body fat percent stemming from caloric restriction influenced by intermittent fasting, but research still shows an overall positive effect on blood sugar levels when intermittent fasting .

Intermittent fasting may help improve glycemic control and insulin resistance with a reduction in weight in those with diabetes and those without.

A Word Of Caution About 24

The Truth About Intermittent Fasting

Its a fact that some of these IF plans are more advanced and not recommended for everyone.

Further, even the author of Healthy Happy Warriors says, there is little scientific evidence to back up the validity of this .

Yet, there are doctors, professors, health gurus, and studies published either claiming IF is safe, or that it is as effective than regular reduced-calorie diets.

Still, while IF has its benefits, it is still controversial in many circles. First, the original studies on IF were conducted on rats .

Of the studies that were done, found no significant differences in fasting glucose and fasting insulin but saw a significant increase in low-density lipoprotein cholesterol levels. However, a meta-analysis of four other IF studies noticed a decrease in LDL cholesterol.

Any diet must be sustainable. The best diets are those a patient can maintain. People are often looking for this one magical something that is going to work, and the point is, theres no one right diet for everyone.

âAlisa Scherban, Yale Health Nutritionist

Thus, many scientists say there arent enough high-quality human studies to conclusively claim similar benefits in people. The Harvard School of Public Health adds that it is unclear if intermittent fasting is superior to other weight loss methods for losing weight and decreasing appetite .

Don’t Miss: How Long You Should Do Intermittent Fasting

Eating Two Mealsmaximum Benefit

The last option is to eat only two meals within your 12-hour eating window. With most intermittent fasting methods, you only have one long fast per day. But with this option, you have two long fasts! You only raise your blood sugar and insulin levelstwo times per day, which is a very effective method to improve insulin sensitivity .

This approach is ideal for people who like to have breakfast and enjoy a social dinner with their family and friends but donât care much about lunch. You can even use the lunch hour to go for a walk or do some exercise.

One concern is that a 12-hour fast is not long enough to induce autophagyâa recycling program that is responsible for many intermittent fasting benefits. There is very little research about the timing of autophagy, and it depends on many factors such as age, underlying conditions, physical activity, and what and how much you eat.

In one study with moderately overweight participants, autophagy could be measured after 18 hours of fasting . However, that does not mean that autophagy cannot begin sooner. If you feel comfortable with 12-hour fasting, and it suits your lifestyle, you can occasionally fast longer to make sure that you stimulate autophagy.

May Aid In Cancer Prevention And Increase The Effectiveness Of Chemotherapy

Animal and test-tube studies indicate that fasting may benefit the treatment and prevention of cancer.

In fact, one rat study found that alternate-day fasting helped block tumor formation .

Similarly, a test-tube study showed that exposing cancer cells to several cycles of fasting was as effective as chemotherapy in delaying tumor growth and increased the effectiveness of chemotherapy drugs on cancer formation .

Unfortunately, most research is limited to the effects of fasting on cancer formation in animals and cells.

Despite these promising findings, additional studies are needed to look at how fasting may influence cancer development and treatment in humans.

Summary Some animal and test-tube studies suggest that fasting could block tumor development and increase the effectiveness of chemotherapy.

Skipping Meals Can Cause Headaches Dizziness And Nausea

Long periods of fasting can lower your blood sugar levels and leave you feeling lightheaded, dizzy, with headaches, and/or nausea.

If you have a medical condition, talk to your doctor to make sure itâs safe to try intermittent fasting. People with type 1 diabetes and/or on diabetic medications may be more susceptible to unwanted side effects or struggle with controlling their blood sugar levels .

Your body will also need some time to adjust, so try choosing a day of the week or period of time that you dont need to be very active or deeply concentrate when first starting a fasting practice.
