Before You Try Intermittent Fasting

If you want to give intermittent fasting a try, make sure to discuss it with your doctor first, says Dr. Rimm. Skipping meals and severely limiting calories can be dangerous for people with certain conditions, such as diabetes. Some people who take medications for blood pressure or heart disease also may be more prone to imbalances of sodium, potassium, and other minerals during longer-than-normal periods of fasting.

Intermittent Fasting For Weight Loss

To continue with the point made above, weight loss is usually the reason people look into an intermittent fasting program. And theres good reason for this: it works.

Intermittent fasting can promote fat loss in a few important ways:

Youll Eat Less: Since you only have an eight-hour window to consume all of your calories for the day, you will naturally eat less . This means youll eat fewer calories without realizing it, and this is going to have a positive impact on your weight loss results.

Your Insulin Response Improves: If youre constantly eating, your insulin levels stay elevated. Over time, this can have a negative impact on the response and effectiveness of insulin. Fasting has been shown to decrease insulin levels and improve long-term response. In turn, this helps to increase digestion, nutrition uptake, and weight loss.

Healthy Growth Hormone Levels: Fasting has been shown to promote the release of healthy growth hormone, which is necessary for recovery and metabolism.

Foods To Avoid On 16/8 Intermittent Fasting

Pin on diet

During your eating window on any method of intermittent fasting, you should stick to the foods presented above. Foods that you need to exclude from the IF food list are:

  • Candy
  • Baked goods

All processed foods, junk food, refined grains, trans-fat, processed meat, candy bars should be excluded from your list of foods for the 16/8 intermittent fasting method or any other IF protocol.

Lowers The Risk Of Type Ii Diabetes

Since being overweight and obese are two of the main risk factors for developing type II diabetes, intermittent fasting could have an effect on diabetes prevention due to its weight loss effects. It can also potentially influence other factors linked to an increased risk of diabetes. A 2014 study showed that intermittent fasting can lower blood glucose and insulin levels in people at risk of diabetes .

Does Intermittent Fasting Negatively Impact Your Metabolism

Siim Land mentions a good point in his video. Through skipping meals, such as during intermittent fasting, theres the belief that you could hurt your metabolism in the end, slowing it. As you may know, those with sluggish metabolisms often have a more difficult time losing weight compared to someone with a faster metabolism.

Is this what youre in for if you begin intermittent fasting? It could be. Siim Land says your total body expenditure can end up dropping if you also lessen non-exercise activity thermogenesis during your fast.

Non-exercise activity thermogenesis refers to anything you do thats not exercising. From going shopping to gardening, raking up the yard, walking your dog, mowing the lawn, or ascending a flight of stairs, these are all examples of non-exercise activity thermogenesis. There are countless other examples as well.

When you dont have as much energy because youre eating less, you may unintentionally do less in your life. This reduces your non-exercise activity thermogenesis. By continuing this behavior, yes, its possible you could end up slowing down your metabolism. However, being aware of what youre doing is half the battle here.

You wont have as much energy as usual while fasting, and you shouldnt ever force yourself, but do try to engage in more non-exercise activity thermogenesis.

How Can I Suppress Hunger During Intermittent Fasting

Eat high-fiber foods, such as nuts, beans, fruits and vegetables, and high protein foods, including meat, fish, tofu, or nuts, during your eating window, Varady advised. Chewing high-fiber gummies can also help.

Drink lots of water. People tend to think they’re hungry, when they are really just thirsty, she said.

Go for black coffee or tea, or cinnamon or licorice herbal teas. These beverages may have appetite-suppressing effects, Varady noted.

Watch less TV: I know this sounds strange, but while you are watching TV, you are bombarded with dozens of ads for food. This can make you feel hungry, when in actuality, you are not hungry at all, she said.

Remember, being “a little hungry” is the best thing that can happen to you, wrote Madelyn Fernstrom, health and nutrition editor at NBC News, calling it a “true mind-body connection” that helps you recognize fullness.

When Can I Eat On The 1: 8 Diet

Do Calories Matter When Intermittent Fasting?

You can pick an 8 hour window to suit your day. So, for example it could be between 10am 6pm or 11am 8pm and so on. Plus, you can still drink tea and coffee outside of those hours too, although because of the benefits of drinking water you are also encouraged to stay as hydrated as possible.

Most people choose to fast through the night, and opt to eat their first meal at about 11am or in the middle of the day.

Tom says, The most common hours adopted for the eating period is 12 till 8pm. The reason for this is because people arent normally that hungry in the morning, you dont want to be consuming too many calories during the evening and this allows us to eat our lunch and dinner as well as a healthy snack.

Intermittent Fasting And Weight Loss

Weight loss is the primary motivator for many to try intermittent fasting. Reports of weight loss of 3 to 8 percent of body weight lost in 3 to 24 weeks have been reported. For a 200-pound person, this is approximately 6 to 16 pounds. While weight loss from fasting isn’t debated, research studies vary as to whether intermittent fasting is an effective long-term dieting method.

There are other health perks though that appear to come from intermittent fasting. When compared to traditional dieting, research suggests that intermittent fasting:

  • Causes greater fat loss in abdominal area
  • Causes less loss of lean body mass
  • Improves cholesterol numbers and fasting insulin

What Are The Proposed Health Benefits Of Fasting Diets

As mentioned, the research on intermittent fasting is limited, but mice studies and small studies in humans suggest the approach may in fact be effective.

For example, in one of Varadys studies, published in June 2018 in Nutrition and Healthy Aging, 23 human participants completed 12 weeks of eight-hour time-restricted eating, and researchers compared their weight loss results to a control group from a separate trial.

Varady and her team observed that the time-restricted group lowered their body weight by 3 percent more on average compared with the control group, and they significantly lowered their systolic blood pressure. But the sample size was small, and the dropout rate among the fasting group was high, at 26 percent, for even a short-term trial, though no one in this group reported dropping out due to issues with the diet, researchers wrote.

But what about alternate-day fasting? While Varady hasnt conducted studies directly comparing alternate-day fasting to time-restricted eating, another one of her studies, published in July 2017 in JAMA Internal Medicine, showed that alternate-day fasting was difficult to stick with and didnt result in better weight loss or heart benefits than a calorie-restricted diet. For the study, she and her team randomized 100 participants to follow one of the two diets or a control group, where their diets remained the same, for one year.

Fasting for five days with juice will just leave you cranky and hungry. But fasting for 16-24 hours throughout the week? Thatll leave you energized and leaner.

Intermittent fasting, as this diet method is known, is just as effective as daily calorie restriction for improving body composition, according to a 2017 study analysis from the International Society of Sports Nutrition.

Unlike calorie restriction, though, intermittent fasting doesnt require you to count calories all the timeand its better at preventing hunger.

Furthermore, intermittent fasting is especially good at helping you lose fat while maintaining muscle, rather than losing both , says Krista Varady, Ph.D., an associate professor of kinesiology and nutrition at the University of Illinois at Chicago and key researcher on intermittent fasting. According to a study analysis in Nutrition Reviews, intermittent fasting also helps improve total cholesterol and triglyceride levels in both overweight and normal-weight people. The best part: Theres virtually no downside.

There are three types of intermittent fasting: whole-day fasting, alternate-day fasting, and time-restricted feeding.

Youll see the same benefits from eachthat is, losing fat without losing musclebut, since each type incorporates a different fasting period and fasting frequency, some are better-suited to certain guys and fitness lifestyles.

Mistake #: Youre Eating Too Many Calories

“Does anyone else eat like crazy right when the fast is over and is it normal to have a huge appetite during the feeding period? It is hard for me to get full after a 20 hour fast and I just eat the whole 4 hours. LOL.”

Id venture to guess that this person is eating more calories than whats needed in that 4-hour window. So instead of laughing your way through a marathon all-you-can-eat session, plan for how youll break your fast. Stock up on high-protein foods and/or high-fiber foods . Theyll not only fill you up, but will keep you feeling full.

“If I do a 20:4 fast then I should consume 1500-2000 calories within four hours? Am I understanding this correctly?”

Technically, yes. But depending on a persons body size, eating 2,000 calories in a 4-hour window might not yield any weight loss. I dont know this persons size, though. Now, most people lose weight on 1,500 calories, but one of the pros of IF is that its hard to eat a ton of calories in a short window of time. For some, following IF is an easier way to cut calories and lose weight than simply following a traditional calorie-restricted diet. So if you cant hit the 1,500- or 2,000-calorie mark in 4 hours every day, its OK. If falling below 1,200 calories a day becomes a regular habit, though, reconsider your diet plan.

What To Eat To Break Your 16 Hour Fast

When it is time to break your fast it is best to start with smaller portions of food that are easily digested so you dont overwhelm your digestive system.

Nutrient-dense foods that are easy to digest that contain protein and some healthy fats can break your fast more gently.

We know that you will be hungry after 16 hours of not eating but the worst thing to do here is to break your fast with processed or junk food that is full of fat, carbs, sugar, etc.

Always prepare something that is easily digestible and nutritious. Here are some foods that will help you to break your 16 hour fasting period:

Soups You will know what time your fasting ends. Prepare a soup that contains protein and easily digestible carbs, such as lentils, tofu. Avoid soups with heavy creams or large amounts of raw vegetables.

Smoothies Great option to introduce nutrients to your body since smoothies contain less fiber, than whole raw vegetables and fruits.

Dried fruits Apricots, raisins, dates. Dates are often used to break a fast. They are healthy, nutritious, and very sweet. Learn more about the benefits of dates here!

Fermented foods Kefir or yogurt are also good drinks to break a fast.

Avocados This fruit can be the first choice to eat after fasting for 16 hours.

So when you are ready to break your 16 hour fasting time and start eating first focus on easily tolerated foods that can help replenish important nutrients and electrolytes.

Best Drinks For Your If Hunger Pangs

  • Water

Water is something which I would sip on all the time even if I am not on intermittent fasting. Whats so new about that?

Yeah, we got it. But also, you are fasting so probably you would think to omit water as the first thing in your diet. Heres the strike.

You CAN and you SHOULD stay well hydrated when you are fasting. Water is central to the health of basically every major organ in your body. Youd be foolish to avoid this as part of your fast.

If you are skeptical of breaking your fast by drinking water and inducing an enzymatic effect, you can get hold of plain water or sparkling water.

To add flavor or taste, you can infuse it with slices of lemon, berries, cucumber, or a cold tea infusion.

The amount of water each person should drink varies based on sex, height, weight, activity level, and climate.

But if you cut down on your optimum water intake, you are likely to suffer from major dehydration symptoms and may also risk hampering other body functions.

  • Tea

Heres some good news for tea-lovers! Fasting calls for a binge sipping on your favorite tea .

Feeling colder than usual is common during IF. Tea provides great comfort and is a warm feel to your body while you are fasting.

You can consume from myriads of different teas which might prove beneficial in terms of your health even when you are fasting. Some of the popular ones are-

  • Herbal Tea
  • Green Tea
  • White Tea, without anything, added.
  • Coffee
  • Broth

Who Should Not Do Intermittent Fasting

Well, if you suffer from high blood sugar, have heart issues, or any serious health conditions then refrain from making any significant changes to your dieting without first seeking professional guidance from a doctor and nutritionist.

Intermittent fasting can be dangerous for some people who have diabetes and heart issues due to the restriction of nutrients for an extended period of time. And those with heart issues should be careful to maintain healthy electrolyte levels.

Also, those with eating disorders should not do a fasting regime without consulting with a doctor because a lack of self-control is a big issue for many sufferers which can be detrimental to health. But on the other side of the spectrum, if you know that you may not possess the discipline to be consistent then you might want to implement a typical calorie-restricted diet until you develop better habits conducive to sticking with the eating regime.

Another group who should not attempt to implement intermittent fasting is pregnant women since it may adversely impact the function of ovulation and menstruation according to one study.
