What To Expect With Intermittent Fasting
- You will most likely notice your stomach is grumbling during fasting periods, primarily if you are used to constant grazing throughout the day.
- Fasting may also lead to an increase in the stress hormone, cortisol, which may lead to even more food cravings.
- Overeating and binge eating are two common side effects of intermittent fasting.
- Intermittent fasting is sometimes associated with dehydration because when you do not eat, sometimes you forget to drink. For good health, it is essential to actively stay hydrated throughout the day by drinking, on average, three liters of water.
- You will most likely feel tired because your body is running on less energy than usual, and since fasting can boost stress levels, it can also disrupt your sleep patterns. It is crucial to adopt a healthy, regular sleep pattern and stick to it so you can feel rested on an everyday basis.
- The same biochemistry that regulates mood also regulates appetite with nutrient consumption affecting the activity of neurotransmitters like dopamine and serotonin. Fasting could play a role in anxiety and depression.
- Deregulating your appetite may do the same to your mood and therefore you will most likely feel irritable on occasions when you are fasting.
Eating Junk While Intermittent Fasting
Since highly processed foods not only raise blood sugar and insulin levels but also have a severe pro-inflammatory effect, you should avoid them during intermittent fasting .
Therefore, this one also applies to intermittent fasting:
Eat real food, such as on the previous list!
Correspondingly inadequate nutrition during the eating periods can destroy the health benefits of intermittent fasting.
Thus, do not trust any food in colorful packaging and read the labels thoroughly before you seriously consider eating these garbage foods:
- Ready Meals
- Fast food
If you have one of these foods on your meal plan, you wont get any results, even with intermittent fasting.

According to the analysis published in the Annual Review of Nutrition, all forms of fasting reviewed produced mild to moderate weight loss, 1%-8% from baseline weight, which represents results that are similar to that of more traditional, calorie-restrictive diets. Intermittent fasting regimens may also benefit health by decreasing blood pressure and insulin resistance, and in some cases, cholesterol and triglyceride levels are also lowered. Other health benefits, such as improved appetite regulation and positive changes in the gut microbiome, have also been demonstrated.
The review looked at over 25 research studies involving three types of intermittent fasting:

With intermittent fasting, there is only one basic approach that works for better health and weight loss:
Do not eat during fasting periods!
Otherwise, there are situations where at least small amounts of certain foods may be acceptable.
If you are not yet used to a new, more extended fasting period and find it challenging to maintain the duration, you might benefit from fasting aids.
For example, if you are hungry and irritable after 12 hours but can last for 16 hours with a Bulletproof Coffee, this is probably acceptable.
Since the added fat limits autophagys health benefits, it hardly stimulates insulin secretion at all, and you can continue to burn fat.
After your body has gotten used to intermittent fasting, however, you should be able to go without training wheels.
Eating Windows Vs Fasting Windows

There are actually a variety of intermittent fasting schedules you can follow to determine what hours of the day these windows actually include. We have a handy guide to fasting schedules for you to check out here.

Unknowingly Breaking The Intermittent Fast
Hidden fast breakers are something you should be aware of. Did you know that even the taste of sweetness triggers your brains insulin response? This causes an insulin release and can effectively break the fast. Here is a look at surprise foods, supplements, and products that can bring a fast to a halt and cause an insulin response:

- Vitamins, such as gummy bear vitamins, contain sugar and fat
- Using toothpaste and mouthwash containing the sweetener xylitol

Intermittent Fasting And Diarrhea After Eating
If you have just started intermittent fasting, it is often quite natural to excrete excess water and electrolytes through the gastrointestinal tract as soon as you break the fast.
Therefore, diarrhea on intermittent fasting is only an issue if it persists.
Against this background, a poor diet can cause diarrhea when fasting. The following food often contributes to diarrhea on intermittent fasting:
- Refined carbohydrates
If you do still suffer from diarrhea when excluding these foods, make sure you drink enough water. Moreover, broth, pickle juice, or sea salt can help to reabsorb the electrolytes you excreted.
Top 6 Questions About Intermittent Fasting
1) Wont I get really hungry if I start skipping meals?
As explained above, this can be a result of the habits you have built for your body. If you are constantly eating or always eat the same time of day, your body can actually learn to prepare itself for food by beginning the process of insulin production and preparation for food.
After a brief adjustment period, your body can adapt to the fact that its only eating a few times a day. The more overweight you are, and the more often you eat, the more of an initial struggle this might be.
Remember, your bodys physical and cognitive abilities most likley wont be diminished as a result of short term fasting.
2) Where will I get my energy for my workouts? Wont I be exhausted and not be able to complete my workouts if fasting?
This was a major concern of mine as well, but the research says otherwise: Training with limited carbohydrate availability can stimulate adaptations in muscle cells to facilitate energy production via fat oxidation.
In other words, when you train in a fasted state, your body can get better at burning fat for energy when there are no carbs to pull from!

Keep Your Meal Nourishing
Include a lot of healthy fats, protein and fresh vegetables in your meals while following intermittent fasting. You can also include healthy carbs from foods like brown rice, sweet potatoes etc. Carbs are good for your body and will provide you with the energy to tide over the calorie-deficit you are going to create for the rest of the day.
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.

Restricting Calories In Your Fasting Window
Yes, there is such a thing as reducing your calories too much. Eating less than 1200 calories in your fasting window is not healthy. Not only that, but it can also sabotage your metabolic rate. If you slow your metabolism down too much, you will begin to lose muscle mass as opposed to increasing it.
To avoid this mistake, try prepping your food for the week ahead on the weekend. This gives you balanced, healthy meals ready at your fingertips. When it is time to eat, you can enjoy a healthy, nutritious, and caloric-correct meal.
Be Mindful Not To Overeat
It can be easy to overeat between fasting periods.
Although fasting doesnt emphasize what you eat as much as when you eat, its not designed to be an excuse to eat unhealthy foods.
Overeating and eating junk food between fasting periods can cancel out the health benefits of fasting. Instead, choose minimally processed, whole foods as much as possible for the most overall health benefits.
When youre ready to break your fast, start with foods and drinks that will be gentle on your digestive system. Avoid foods that are especially high in sugar, fat, and fiber. Additionally, take care not to overeat.
