12-Hour Intermittent Fasting For Weight Loss And Other Benefits

Intermittent Fasting

Fasting is depriving your body of food for a specific purpose. People fast for spiritual nourishment, political protest, or for health benefits such as losing weight. In intermittent fasting (IF), a person follows a pattern of eating and fasting cycles that deprive the body of glucose, forcing it to utilize fat as an energy source. 12 hour intermittent fasting is one of the periodic eating cycles that claims excellent long-term results and may be worth considering.

What is intermittent fasting for 12 hours? 12:12 is one of the IF methods, whereby instead of eating any time you please, you are restricted to consuming your daily caloric intake within 12 hours, then go without food for the next 12 hours (6). The daily 12 hour fasting window will cause the body to convert its fat stores into energy over time, releasing ketones into the bloodstream. One of its potential outcomes is weight loss. Unlike other weight-loss diets, IF focuses on when you should eat, instead of the foods that you should consume.

How To Do The 12-Hour Intermittent Fasting?

When following this IF method, in as much as the two meals are 12 hours apart, you must finish your last meal before the 12 hour fasting-eating interval. For instance, if your eating window is 8 a.m. to 8 p.m., you should eat breakfast at or after 8 a.m. finish dinner before 8 p.m. As you begin, you will have hunger pains, but your body will adjust with time.

Do not jump into the 12 hour intermittent fasting. Your body takes time to adjust to not eating, especially if you usually take three meals and two snacks a day. Begin by staying off some meals, then when you get used to staying without food for hours, increase the period slowly to the 12 hours optimal window. Ensure that you are comfortable staying for long without eating because 12 hour intermittent fasting should not make you miserable, but rather, you should enjoy doing it.

Intermittent Fasting And Sleeping

Besides staying without food for the said period, it is better to sleep during the fasting hours. Intermittent 12 hour fasting at night is easier because you will be asleep for the most part, say 7 hours. However, if you fast during the day, you may need to take a nap and keep yourself busy to avoid thinking about food that will lead to relapse.

You can begin by fasting weekly, then on several days of the week before making it a day to day routine. If you are fasting for specific days a week, for example, five days a week, eat as usual on the non-fasting days. Note that you may become irritable, and your concentration may momentarily dip during the fasting period as you begin this healthy journey. The good news is that your body will adjust within a month, and the side effects should disappear. If they are particularly severe or don’t go away, consider stopping your fasting routine and discuss with your doctor.

What Can You Eat During The 12-Hour Intermittent Fasting?

To enjoy the benefits of depriving yourself of food for 12 hours, you need to consume nutritious foods during your eating window. These include healthy fats, whole grains, and healthy proteins. However, you should limit your intake of saturated fats and avoid refined carbohydrates and sugar.

Examples Of Healthy Foods 

  • Avocados are recommended because they have monounsaturated fats that are very satisfying. Taking avocado with your meals can make you full for hours longer than if you did not include it in the meal.
  • A large egg contains 6 grams of proteins, which is important for keeping you satisfied and building muscle.
  • Beans and legumes have low-calorie and high-fiber carbs.
  • Berries have vital nutrients such as vitamin C that boosts immunity.
  • Fish is rich in healthy omega-3 fats, protein, and vitamin D.
  • Kefir, Kombucha, or Kraut are probiotic-rich foods that can be included in the meals.
  • Nuts have good fats. For instance, the polyunsaturated fats in walnuts alter biological markers for satiety and hunger.
  • Potatoes can help in weight loss. Just be sure to prepare them healthily. For instance, avoid French fries or potato chips and go for roasted, boiled, or mashed potatoes.
  • Vegetables such as broccoli, cauliflower, and Brussels sprouts contain fiber, preventing constipation, and making you feel full. This will help you feel comfortable without food for 12 hours.
  • Whole grains such as sorghum, millet, and bulgur have fiber and protein, therefore making you feel full. They also turn up your metabolic rate.

While fasting, you can take water, tea, and other calorie-free drinks. These fluids are essential because your body has no alternative source of fluids other than what you drink. You can monitor your hydration levels by inspecting your urine. Pale yellow or clear means you are okay, while dark-yellow urine is a sign of dehydration and can lead to headache, fatigue, or lightheadedness. If you do not like plain water, you can add lemon, mint, or cucumber to the water.


What Are The Benefits Of The 12-Hour Intermittent Fasting?

Greek Physician Hippocrates and Athein and philosopher Plato are among the early proponents of the benefits of fasting to improve health, thousands of years back. Plato fasted for better physical and mental productivity. And according to Hippocrates, our food should be our medicine, and to eat when you are sick is to feed your sickness (3). Fast forward to today, modern science agrees that having a full stomach all the time is not ideal.

After eating, many new proteins are produced in the brain, and during fasting, the body also produces few new proteins. Therefore, cells are prompted to obtain protein from non-essential sources, convert them, and use the amino acids to make new proteins needed to survive.

The benefits of intermittent 12-hour fasting include:

  • Losing weight

How does IF lead to weight loss? Usually, after eating, glucose is utilized for energy, and fat is kept in the fat tissue. However, once glucose is exhausted when fasting, the body turns to the energy stored in fat cells. It is thought to take up to 12 hours for the body to utilize the liver’s stored glucose (glycogen) before a metabolic shift to the utilization of stored fats. When you eat at an interval of 12 hours, the body is forced to tap into stored fat reserves, and with time, this leads to weight loss.

According to the New York Times, time-restricted fasting could help you consume around 550 calories less than usual, which is difficult to achieve with an ordinary calorie-restricted diet (4). Since intermittent 12-hour fasting is one of the IF techniques, you can be sure to enjoy this calorie deficit by following the routine. A review published by a WHO regional office also confirms that time-restricted feeding has reported positive health effects, one of them being weight reduction (1).

How long does it take to see weight loss?

How long does it take to see weight loss to 12 hour daily intermittent fasting? IF is not a quick fix, but a steady, healthy, weight-loss alternative. According to experts, 12 hour intermittent fasting results can be visible after at least ten weeks of following the routine. The average weight loss within this period is between 7 and 10 pounds.

Note that each person has a different metabolism. It may take longer for the results to be seen in some people, and the number of pounds lost also differs. Losing weight too fast may be an indication that you are restricting too much, so you should re-evaluate your calorie intake. Besides, this weight-loss method may not work if you have gut imbalances, vitamin deficiencies, hormone issues, sleep issues, or a liver requiring detox. Seek professional advice before beginning this routine.

  • Improved workouts

Exercising with restricted carbohydrate availability can stimulate variations in muscle cells to expedite energy production via fat oxidation. This means that exercising while fasting makes your body better at burning fat for energy because there are no foods to pull from. According to NCBI, fasting impacts on human physiological and biochemical parameters that are significant for athletic performance, and it decreases body weight (2). With improved workouts, you can easily attain your weight loss goal.

  • Enhances detox

The human body is always trying to detoxify itself. Just like any other seemingly bodily process like digestion, detoxification burns calories. Therefore, if not busy digesting, the body concentrates its energy on getting rid of toxins.

  • Reduces inflammation

By turning on the NRF2 gene pathway, fasting produces a great increase in antioxidant protection, enhances detoxification, and decreases inflammation.

  • Lengthening life

When you fast, your body finds a way of extending life. Restricting calories has been established to lengthen life. IF stimulates many of the same mechanisms for prolonging life as calorie-restriction.

Since you are eating healthier and consuming fewer calories, 12 hour intermittent fasting results also include enhanced brain health because it supports mitochondrial wellbeing. The 12:12 also has an impact on cholesterol, triglycerides, and blood sugar levels. More studies are being conducted to establish if it minimizes the risk of cancer. Due to facilitating weight loss, IF reduces the progression of type 2 diabetes, cardiovascular risk, neurological disorders, and circadian rhythm disorders, among other outcomes.

Final Thought

12 hour intermittent fasting is a sustainable IF method with amazing outcomes. Try weight loss with 12 hour intermittent fasting, and if you are not experiencing nutritional deficiencies, you should make this a lifestyle by following the cycle long term. Happy fasting!

Sticking to a healthy diet based on your health needs, allergies and preferences is a great idea, however when combined with a workout plan that meets your goals, it might bring you significant benefits. Better mood, stronger muscles and endurance are just some.
