In the case of intermittent fasting and hypothyroidism, is it safe to practice intermittent fasting at the same time?

Throughout human history, people have fasted for a wide range of reasons. Historically, people have turned to fast for various reasons, including medical, religious, and political treatment, as well as during times of severe food shortage. Fasting can have a positive impact on one's health and quality of life if it is done correctly. The ancient Greeks were the first to notice and record the benefits of fasting. As a result of the lack of a consistent supply of food that was accessible to our ancestors, fasting is a practice that plays a significant role in the evolution of our species. The increasing popularity of intermittent fasting may be due to the many health benefits it has been shown to have.

What Exactly Does It Mean To Fast Intermittently?

Following a rhythm of alternating periods of eating and fasting is known as intermittent fasting (IF). An eating pattern dependent on the amount of time between meals, as opposed to diets that limit particular foods, is known as intermittent fasting. People might adhere to various fasting schedules when they engage in intermittent fasting.

Irrespective of why people engage in intermittent fasting, their decision has many different motivations. People may opt to fast for their health to reduce weight, regulate inflammation, lower insulin resistance, and enhance cognitive function. These goals may be accomplished by fasting. Intermittent fasting for religious reasons might be done to purify the body or represent one's willingness to make a sacrifice. For many Christians who follow this custom, the period known as Lent is set aside as a time to abstain from food and drink. Similarly, Ramadan is a time for Muslims to abstain from food and drink.

People who prefer to occasionally fast for health reasons have various eating cycles and patterns from which they might pick. While some IF practices revolve around a 24-hour window, others may be spread over a week.

5:2 Abstinence And Fasting

On five days out of the week, people consume meals and quantities that are usual for them. On the other two days of the week, the daily calorie intake is restricted to around 500 calories. For instance, a person may decide to limit the number of calories they consume on Tuesday and Friday of each week by eating two meals that are each around 250 calories in size. Your calorie needs on days when you are fasting may vary depending on your health concerns and whether you are a man or a female.

A Method Using 16/8 Time

This kind of IF entails going without food for 16 hours, followed by an eating window of 8 hours. Most individuals generally finish eating about 8 PM and do not eat again until midnight the following day. Fasting for 14 to 15 hours is often beneficial for the health of women who follow this routine. You may stave off the hungry sensations you get in the morning by drinking liquids without calories, such as water or coffee (without the sweet and creamy additives).

A Fast That Lasts All Night

Most of us already adhere to a fast of this length daily, making it one of the most accessible forms of intermittent fasting (IF) to follow. Because it prevents you from eating late at night, fasting overnight may be suitable for your weight and metabolism.

Intermittent Or Cyclical Fasting

People looking for results in their weight reduction efforts often choose this option. In this approach, you will follow a pattern in which you usually eat one day and then refrain from eating the next day. On fasting days, some persons who adopt this form of intermittent fasting (IF) may choose to consume a relatively low quantity of calories.

Fasting For The Entire Day

With this strategy, you limit your eating to one very substantial meal daily, leaving you without food for the other 24 hours of the day. For instance, some individuals choose to have a hearty supper once each week and then go the rest of the week without taking in any food until the following week's dinner.

To maintain metabolic homeostasis, enough fasting is required, mainly when one is sleeping. It makes it possible for sugar and insulin levels in the blood to recover to their normal levels.

Consuming food in the absence of sufficient time spent fasting may lead to prolonged hyperglycemia, often known as high blood sugar levels and increased insulin production. A high amount of blood sugar disrupts the normal function of cells and leads to inflammation, increasing insulin resistance. While creating insulin, your pancreas produces a hormone that transports sugar from your bloodstream into your cells, which you can use as fuel for your body. Insulin is a hormone released by the pancreas, and insulin has a role in energy storage.

Although cells develop a resistance to insulin's function in the absorption of blood sugar, they continue to be receptive to insulin's role in the storage of fat. Because of this, higher body fat is linked to insulin resistance and high blood sugar levels.

The goal of weight reduction is by far the most prevalent motivation for individuals to engage in intermittent fasting. According to the findings of several studies, abstaining from food intake for an extended period results in hormonal adjustments that trigger the release of fat reserves for usage as a source of energy. In addition to the reduction of weight, intermittent fasting is connected with several other positive health effects, including the following:

  • You are increasing your levels of norepinephrine, which in turn will give your metabolism a boost.
  • The modification of unhealthful eating practices
  • Reducing your blood pressure and LDL cholesterol levels may significantly reduce your risk of cardiovascular disease.
  • Reduced levels of inflammatory markers, which are linked to an increased risk of chronic diseases such as cancer and autoimmune disorders
  • Enhancing the ability to regulate blood sugar by decreasing insulin resistance
  • Increasing the amount of human growth hormone (HGH), which aids in the construction of muscles, the reduction of body fat, and the acceleration of metabolic activity

The practice of fasting is not without its accompanying dangers. For example, people with diabetes or problems controlling their blood sugar may risk low blood sugar levels (hypoglycemia). At the same time, they fast, which may endanger their lives.

However, the most crucial consideration for most people when engaging in intermittent fasting is likely sustainability. Including fasting in your professional, social, and health routines may be challenging, and this is particularly true for those who maintain irregular hours or do not have a regular schedule. No matter the dietary strategy you choose, you should make maintaining consistency and your general health a long-term priority.

Some people may develop new disordered eating habits due to intermittent fasting, or it may bring back behaviors they had in the past.

Keep in mind that the more pressure you place on yourself to maintain a specific diet, the greater the likelihood that you may develop inflammation. This inflammation may make your autoimmune responses more severe or interfere with your thyroid function. The reason for this is that we strongly suggest that you look into different methods of nutrition that you will be able to maintain over the long term to achieve the best results.

It is not recommended to engage in intermittent fasting if you are a child, an endurance athlete, someone who is underweight, or a woman who is pregnant, nursing, or trying to conceive. Fasting should not be practiced by anyone at risk of malnutrition, such as those who are deficient in specific vitamins or otherwise vulnerable to malnutrition.

Is It Harmless To Your Thyroid To Do So?

Every one of us is unique and with our own set of sensitivities. Some persons with thyroid illness may safely practice intermittent fasting, while others with the condition may suffer negative repercussions. Because the thyroid is the body's metabolic engine, fasting influences the thyroid directly.

New research looked at the impact of fasting every other day in otherwise healthy persons. Those who participated in an experiment alternating 36 hours of calorie restriction with 12 hours of unrestricted eating exhibited lower levels of triiodothyronine than those in the control group (T3). There is evidence to suggest that consuming a low-calorie diet may also reduce T3 levels, as has been shown by other studies.

In another investigation, persons with subclinical hypothyroidism were subjected to comparing the weight-loss potential of daily calorie restriction vs. fasting every other day. After six months, the findings indicated that restricting calories and fasting every other day led to a comparable reduction in body weight. Alternate-day fasting was shown to be more effective than calorie restriction in lowering insulin resistance. Both the TSH and the fT4 levels stayed the same.

Your thyroid medication's metabolism may increase if you engage in intermittent fasting and alter how your body uses available energy. If you suffer from Hashimoto's disease, intermittent fasting at the appropriate intervals may help alleviate inflammation and lessen the impact of this inflammatory disorder on your life.

Suppose you consider utilizing intermittent fasting (IF) to lose weight and reap other health advantages to determine whether or not IF is a viable option for you. A medical professional would need to be consulted to determine whether or not IF might be the best option for you.
