What Is a 16/8 Intermittent Fasting Diet?

There are several types of intermittent fasting regimens. The strategy behind each is to choose a period during which to eat and then fast for the remainder of the time.

The most common intermittent fasting diet is the 16/8 intermittent fasting 7-day meal plan. This plan involves eating for 8 hours each day and then fasting for the remaining 16 hours.

Intermittent fasting helps you lose weight by prolonging the time your body will be required to use its fat stores because you’re not ingesting calories.

Benefits of a 16/8 Intermittent Fasting 7-Day Meal Plan

The 16/8 method is popular for a reason: it’s relatively easy to follow and offers some potential health benefits. Let’s break down what you might experience by following a 16/8 intermittent fasting plan for 7 days, combined with a healthy diet:

Improved Blood Sugar Control

Fasting increases insulin sensitivity and decreases insulin levels. This results in improved blood sugar levels during the fast and immediately after eating. It may also contribute to healthier blood pressure readings.

Weight Loss

An article published online by the National Institutes of Health determined that people with type 2 diabetes lost more weight by fasting daily than by restricting calorie intake [1].

Improved Metabolism

An intermittent fasting plan can boost your metabolism by causing your body to switch from using glucose to using fat for energy. It also helps to increase the hormones that promote fat loss, like norepinephrine and HGH (Human Growth Hormone).

Boosted Brain Health

One benefit of an intermittent fasting diet involves triggering the production of brain-derived neurotrophic factor (BDNF), a protein affecting neuron growth, cognitive function, memory, and learning.

Healthy Aging

When the body is in a fasting state, cellular repair functions like autophagy are activated, reducing oxidative stress and optimizing energy metabolism to slow down aging. 

Disadvantages of the 16/8 Intermittent Fasting 7-Day Meal Plan

While 16/8 intermittent fasting can be beneficial for many, it’s not without potential drawbacks. Here are some disadvantages to consider, especially in the context of a 7-day meal plan:

Overeating and Weight Gain

According to an article published by Harvard Health, an intermittent fasting diet can cause overeating because depriving the body of food accelerates appetite hormones and the hunger center in the brain [2]. Natural appetite suppressants might help with this.

Unwanted Short-term Symptoms

A 16/8 Intermittent fasting 7-day meal plan can cause short-term symptoms like hunger, fatigue, headaches, dizziness, irritability, mood swings, and more until you get used to it.

Hormonal Changes

An NIH study on intermittent fasting and hormonal changes determined that a plan to fast intermittently can adversely affect the reproductive hormone levels in both men and women [3].

Potential Changes In Menstrual Cycles

An intermittent fasting plan can influence your menstrual cycle by lowering the levels of the neuropeptide hormone kisspeptin, which directly affects estrogen production.

Preparing for Intermittent Fasting: How to Get a Good Start

Jumping into intermittent fasting without a plan can make it harder to stick with and increase the chance of uncomfortable side effects. Let’s explore a few things to consider to help you get off to a good start:

Consult With Your Doctor

Fasting is a shock to your body, especially if you’re used to certain regular caloric intakes. Therefore, it is essential to consult with your doctor before considering an intermittent fasting schedule.

Choose a Suitable Time Frame

The most popular time frame for a 16/8 intermittent fasting 7-day meal plan is to schedule your meals between 12 p.m. and 8 p.m. This will allow you to eat a normal lunch and dinner, fast overnight while sleeping, and then skip breakfast. 

Prepare a Suitable Meal Plan

When choosing a 16/8 intermittent 7-day meal plan, make sure that the meals you prepare include protein, healthy fats, and other nutritious whole foods. Whole grains are an excellent source of fiber, which can help you feel full and satisfied during your eating window.

A 16/8 intermittent fasting 7-day meal plan for vegetarians should include a variety of fruits, vegetables, whole grains, legumes, nuts, and seeds to ensure they obtain all the essential nutrients typically found in animal products.

Simple Tips for Successful 16/8 Intermittent Fasting

Here are some simple tips to make your 16/8 intermittent fasting journey smoother and more successful, according to our research and the r/askfitness community:

Stay Hydrated

Drinking plenty of fluids is important for staying hydrated and curbing hunger. Some good choices in addition to water are herbal tea or black coffee.

Prioritize Good Sleep

A study on intermittent fasting and sleep determined that fasting can help improve REM sleep and balance circadian rhythms. Likewise, it was shown that when body weight is reduced by fasting, sleep patterns and quality of sleep are subsequently enhanced [4].

Replenish Minerals

Drinking mineral water is a good way to replenish minerals during a 16/8 intermittent fasting 77-day meal plan. You should also take a good magnesium supplement because magnesium is one of the most utilized minerals in the body and depletes quickly while fasting. 

Start With a Balanced Meal

During intermittent fasting, start your day with a balanced meal that includes lean protein, low carbs, healthy fats, and good-quality fiber from fruits and veggies. 

Plus, you can consider incorporating elements of the Mediterranean diet, such as Meatless Mondays or incorporating more fish into your weekly meal prep, to further enhance the benefits of 16/8 intermittent fasting.

Drink Green Tea or Coffee

Both Green tea and coffee can provide an energy boost during a fast, yet coffee’s 

caffeine content can upset your stomach, affect calcium absorption, and weaken bones.

Consider Adding Supplements to Your Diet

You can take supplements while fasting, but keep in mind that fat-soluble vitamins like A, D, E, and K usually work better with food. Taking them on an empty stomach will break your fast and may cause stomach upset. Water-soluble vitamins B and C can be taken with just water and would not break a fast.

Always Listen to Your Body

It’s crucial to remember that a 16/8 intermittent fasting 7-day meal plan can initially shock your system if you’re not used to it. That means you should always consult your doctor beforehand and listen to the signals your body sends you during the fast. 

Is a 16/8 Intermittent Fasting 7-Day Meal Plan Suitable for You?

A 16/8 intermittent fasting 7-day meal plan is not suitable for everyone. If you are under 18, pregnant or breastfeeding, and have type 1 diabetes or an eating disorder, you should avoid intermittent fasting.

Other Types of Intermittent Fasting Plans

16/8 is popular, but it’s not a one-size-fits-all plan. Here are some other common intermittent fasting plans:

5:2 Fasting

A 5:2 intermittent fasting schedule involves eating regularly for 5 days and limiting your caloric intake by about 75% for the remaining 2 days. This type of fasting diet is considered effective for weight loss. One animal study cited it as leading to a reduction in stored fat tissue [5].

14:10 Fasting

This type of intermittent fasting plan breaks a 24-hour day into 14 hours of fasting and a 10-hour window for eating. It is a bit less stringent than the 16/8 plan and is considered a beginner-friendly option.

Eat-Stop-Eat

Made popular by the book “Eat Stop Eat” by Brad Pilon, this type of intermittent fasting diet consists of fasting for a full 24 hours once or twice a week and then eating normally on other days.

Although research on this method is limited, its reduced calorie intake and the metabolic changes it causes may help with weight loss.

Alternate Day Fasting

The theory behind alternate-day fasting (ADF) is that you alternate between 24-hour periods of fasting and eating. During the fasting period, you can either completely abstain from eating or have a meal of 500 calories or less. ADF may lower the risk of type 2 diabetes and promote heart health [6].
