What You Eat Matters
Many people abuse intermittent fasting to maintain their habitual Western diet, which is dominated by refined carbohydrates.
However, what you eat makes a big difference even with intermittent fasting.
People especially like to lie to themselves with alternate day fasting. Perhaps you, too, have acquaintances who practice this method in exchange for stuffing themselves with low-nutrient, high-carbohydrate foods.
Nonetheless, intermittent fasting revolves around two effects:
- Fat burning
- Sustainable health
What people tend to forget is that research has shown that both goals depend on hormone balance.
When the storage hormone insulin is too high, the body can neither cleanse itself through autophagy nor break down stored fat .
For this reason, the desired results fail to materialize when people use intermittent fasting to cheat.
In addition, the constant switch between sugar and fat metabolism brings physical side effects, such as headaches or even diarrhea in particular.
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:
- Dairy
- Refined carbohydrates
- Legumes
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.
Sleep More Eat Healthier
Adults need at least 7 hours of sleep a night for optimal health, according to the American Academy of Sleep Medicine and the Sleep Research Society. But most fall short, and that can influence eating habits and metabolism.
In one study, 16 people slept for 9 hours a night for five days , then switched to 5 hours a night for five days.
Sleeping just 5 hours disrupted their circadian rhythm, which led them to take in excess calories, gain weight, and experience an almost 20 percent drop in insulin sensitivity.
Insufficient sleep seems to prompt evening eating, McHill says. And its those calories that seem to account for the weight gain and metabolic issues.
What you eat can also disrupt sleep. Consuming spicy foods close to bedtime may upset your digestive system, and caffeine may delay the onset of melatonin. Research also suggests that eating lots of added sugars and processed grains may trigger insomnia, while eating more vegetables and fruit may help prevent it.

Can You Eat Anything When Intermittent Fasting
Theoretically, you can eat anything during the 8 hours of eating on intermittent fasting. However, this way, you wont see results.
With this in mind, people often try fasting to reward themselves with junk food afterward. Thereby alternate-day fasting is incredibly popular.
Maybe you have heard like me from friends who follow this method sporadically and unsuccessfully. Therefore, the following must be clear with intermittent fasting:
- Discipline is mandatory
- It cannot replace quality food
If you gulp down fries and beer during the eating periods, you definitely wont approach the body of your dreams. Even on intermittent fasting, food quality remains crucial for your health and weight loss.
If you eat less often, it is essential to provide your body with natural nutrient-dense food.
People who delude themselves when eating on an intermittent fasting program wont get results. Beyond that, grasping refined carbohydrates and sweeteners is a vicious cycle, inducing cravings that can turn fasting into agony.
Well further deal with the topic when discussing what not to eat when intermittent fasting.
When To Eat Carbs On Intermittent Fasting
Since no essential carbohydrates exist, the body does not need them to survive. However, our body cannot produce essential fatty acids and amino acids.
But because it can produce glucose through gluconeogenesis, blood sugar levels remain stable if you eat zero carbs .
Nevertheless, there are situations with intermittent fasting where carbohydrates can fit well into the diet.
For example, many athletes do not want to do without carbohydrates, as they continuously empty their glycogen stores. Adding carbohydrates to their diet can contribute to muscle recovery .
Thus, you can time carbohydrates very well during intermittent fasting:
- Training day: More carbohydrates replenishing glycogen stores in the muscles
- Rest day: low-carb or ketogenic diet
Accordingly, you can adapt your intermittent fasting plan to athletic needs through carb-cycling or cyclical ketogenic nutrition.
Nevertheless, so-called loading days are not necessary for muscle building as long as the protein supply is given .
Although the insulin levels increased by carbohydrates can help the muscles recover, it also helps build body fat more efficiently .
For this reason, bodybuilders often claim that they cant gain muscle without also building up body fat.
In short, a low carbohydrate ketogenic diet is still the best option if losing weight is your primary goal.

I Got Better At Planning
The first few days, when I was finally allowed to eat, I mostly ate tons of healthy snacks because I was ravenous. Almonds, apples and peanut butter, pretzels, hummus, and cheeseyou get the picture. But eventually, I started being more conscious of the food I ate and wrote everything down in a diary to keep track.
Instead of the mindless snacks that were easy to lose track of, I mapped out meals and the snacks I could eat in between. Moskovitz advised me to make sure the diet wasn’t causing me to miss out on nutrients I get during a normal day of eating, so I found that writing down my meals in advance helped me make sure I was getting enough of everything. If I knew I was going out to eat, I would leave a blank and fill it in with whatever I ordered the next day.
Vitamin D Fortified Milk
The recommended intake of calcium for an adult is 1,000 milligrams per day, about what you’d get by drinking three cups of milk per day. With a reduced feeding window, the opportunities to drink this much might be scarce, and so it is important to prioritize high-calcium foods. Vitamin D fortified milk enhances the body’s absorption of calcium and will help to keep bones strong. To boost daily calcium intake, you can add milk to smoothies or cereal, or even just drink it with meals. If you’re not a fan of the beverage, non-dairy sources high in calcium include tofu and soy products, as well as leafy greens like kale.

You Are Consuming Too Many Calories
Youâre not alone, according to Mills. âIt can be easy to overeat when a fast breaks, either because youâre feeling ravenous or you justify to yourself that youâre making up for lost calories.â She advises to use a scale of 0-10 where 0 is famished and 10 is stuffed. You should feel hungry before eating and you should stop eating when youâre full, not just to clean your plate. She also recommends slowing down while eating so your brain has time to signal when youâre getting full. âIt may take 15-20 minutes after you start eating,â Mills notes.

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
- Dressings
- Fast food
If you have one of these foods on your meal plan, you wont get any results, even with intermittent fasting.

Types Of Intermittent Fasting
There are multiple types of intermittent fasting to choose from when you decide to practice this eating pattern:
- The 5:2 diet: For five days of the week, you eat normally without any restrictions, and on two days of the week you limit your caloric intake to 500 or 600 calories per day. This diet recommends 500 calories for women and 600 calories for men.
- The 16/8 fast: To follow this method, you limit your eating to a window of time that is 8 hours long each day, and you spend the other 16 hours of the day fasting.
- Alternate day fasting: This technique requires a day of fasting every other day. On the first day, you eat normally while on the next day you either fast completely for 24 hours or eat less than 500 calories. This pattern continues throughout the week and may be more intense than is advisable for beginners.
- One meal a day: Only one meal is eaten a day with this type of intermittent fast, and it is usually dinner. During the rest of the day, no calories are consumed.
Foods To Avoid During The Intermittent Fasting
You need to avoid some foods during intermittent fasting to maintain a balanced diet and a healthy lifestyle. Processed foods such as burgers, fries, and nuggets are high in calories, and they can increase your food cravings. These foods contain fat, added sugar, and empty calories.
Here is the list of foods you need to avoid during your intermittent fasting
- Snacks such as fried chips
- Sugary drinks like carbonated drinks, coffee, cold coffee
- Processed, packed juices
- Processed foods such as cheese, meat, etc
- Popcorn
- Candies
Many studies suggest that processed foods and carbonated drinks lead to weight gain. You can replace carbonated drinks with fresh juices and fried foods with healthy salads. Be more mindful while choosing your food to make your intermittent fasting more powerful.

Do You Still Eat 3 Meals When Intermittent Fasting
Intermittent Fasting can still average to 3 meals a day when you do it mindfully. My first meal of the day is a combo of what Id call breakfast and lunch. Ive been making a breakfast burrito for this meal lately, and its so good.
And in the afternoon, Ill have a large snack. If you follow me on , you already know its pretty much the same meal every single day because I love it so much!
But dont worry, I appreciate variety, too! Check out this post on My Fave High Protein Snacks For Weight Loss.
And last but not least, Ill have a small dinner. Most likely another wrap because theyre so easy to put together and filling, too!
Mistake #: Youre Eating Without Realizing It
“I’m trying to cut myself down to one meal a day, so while I’m not actively trying to do IF, I think I’m kind of doing it by proxy . But does this mean no calorie intake whatsoever outside of the time I normally eat? Or just no actual food? Because I have coffee every morning and I’ve also been drinking a cup of soy or almond milk for “breakfast and I don’t know if it’s going to mess with my progress.”
OK, this is intermittent fasting. Period. Even though this person says he or she isnt actively doing IF, they are. Theres nothing sinful about IF, so no need to deny it. But to reap the benefits, you cant have that quote-unquote breakfast. Fasting means no calories during that fasting time period.

When Should I Eat On A Fast Day
For most people, fasting all day and then having a good evening meal is the best plan for a fast day. You will have a small calorie allowance on fast days of 500600 calories. A single 500 calorie meal can be quite substantial, but if you try to spread the calories over breakfast, lunch and dinner, you will only be able to have mini-meals. Most people find that eating just a small amount only cures the hunger pangs for a short time and actually makes them hungrier for the rest of the day, so it is generally best to avoid snacking on fast days and save your calories until you can have a proper meal.
As well as being easier for most people, waiting to eat until the evening is also more effective for weight loss, as you will have fasted for longer. This has been shown by a survey conducted on the FastDay Forum to investigate the factors that influence weight loss on the 5:2 diet. The analysis of our survey questionnaire found that fasting for more than 20 hours on a fast day resulted in a greater weight loss than fasting for less than 16 hours. There are several potential scientific explanations for why this might be.
Some snacks allowed: you may find you hit a bit of a low point at around 4pm. A salty drink or a small snack may be the answer. If you have problems with not sleeping well on a fast day, saving some calories for a snack before bed may be the answer.
How Many Calories To Eat During Intermittent Fasting 16/8
Now that we understand weight gain to be more of a hormonal than a caloric imbalance, we have to keep up with the times and question the outdated calorie counting regime.
For example, an empirical study from Great Britain shows that no less than 99.5 percent of overweight women and men could not lose weight successfully using conventional calorie restriction .
And we are not talking about three people here, but 99,791 women and 76,704 men!
So why is calorie counting still the standard of the fitness industry?
There are probably two main reasons:
- It helps to sell highly processed garbage
- The calorimeter was invented in 1892
Therefore, people know about calories, but not so much about hormones.
Nevertheless, this does not mean that calorie balance does not influence weight loss.
However, the correct meal timing during intermittent fasting makes a substantial hormonal advantage possible.
After insulin levels are low during intermittent fasting for an extended period, you will burn more fat with the same calorie intake.
As long as you dont cheat or have reached goal weight, the standard daily calorie requirement will be sufficient to lose weight during intermittent fasting. For a woman, this is about 1,900 kcal.
According to studies, people who eat fewer meals also consume fewer calories during the day, so you are more likely to fall short of your daily requirement .
