Intermittent fasting-we’ve all likely heard of it, many are doing it, and still others are uncertain about it. For many it’s proven to be a great way to burn fat and lose weight, among other possible benefits. Like most things in life, there are right and wrong ways to do intermittent fasting. Unfortunately, beginners and even those who have been doing it for a while can make common mistakes that not only hamper their results but could also lead to health issues. Regardless of where you stand on the IF spectrum, here are 10 of the most common intermittent fasting mistakes people make and how to avoid them.
Taking a one-size-fits-all approach to intermittent fasting is one of the biggest mistakes people make. Not everyone’s body responds the same way to fasting. What works for some may not work for you.
That’s why it’s important to find a plan that fits your lifestyle, schedule, and goals. It’s important to note that there are many different types of intermittent fasting plans to choose from (5):
Choosing a plan that’s too strict or not well suited for your lifestyle is a recipe for disaster. You’re more likely to cheat or give up altogether if you’re constantly hungry or feeling deprived.
On the flip side, if you choose a plan that’s too lax, you won’t see the results you’re looking for. In addition, you won’t be pushing your body to its full potential.
The best way to find the right intermittent fasting plan is to experiment with different methods until you find one that works for you. Start with a 16/8 split and see how you feel. You can also work in different length fasting windows on different days of the week according to your schedule – like 12/12 or 14/10 on days when 16/8 just doesn’t fit or you don’t feel up to it. If you’re struggling with doing some type of fasting every day, try a 24-hour fast or the 5:2 diet.
Remember, there is no one perfect plan. The key is finding one that you can stick to long-term without feeling deprived or restricted.

The most successful lifestyle changes are the ones that are easiest to stick to. That’s why it’s important to consider your lifestyle when choosing an intermittent fasting plan.
There are several aspects of your lifestyle that determine whether a particular fasting plan will work for you:
Not considering your lifestyle when choosing an intermittent fasting plan can make it very difficult to stick to. You’re more likely to cheat or give up if you’re constantly struggling to fit fasting into your already busy schedule.
The best way to fix this mistake is to choose an intermittent fasting plan that fits your lifestyle. Bear in mind that IF is all about time-restricted eating, so any plan that allows you to eat within a set timeframe will work.
If you have a busy lifestyle, try the 16/8 method or the warrior diet. If you have an active social life, you may find it easier to do a longer fast once or twice a week on days when you don’t have social engagements, like the 24-hour fast or the alternate day fasting method.
People often confuse IF with dieting. This leads to the common misconception that you should eat very little during your eating window. This is not only ineffective, but it can also be dangerous.
In reality, there’s a huge difference between the two. IF restricts the time you eat, while dieting restricts the type and amount of food you eat. The whole point of IF is to give your body a break from digesting food.
Underneath all the fat you’re trying to lose, your body has lean muscle. This muscle is important because it helps you burn calories, even when you’re resting, plus you need it to do all the daily activities of life (6). When you don’t eat enough on fasting days, your body starts to break down this muscle for energy.
This not only slows down your metabolism, but it can also cause muscle wasting and fatigue.
Undereating also makes you more likely to binge eat later. This can offset any weight loss you’ve achieved and make it harder to stick to your plan in the long run.
The best way to fix this mistake is to make sure you’re eating enough during your eating window. How do you know how much is enough?
A good rule of thumb is to calculate your body’s energy and protein needs based on individual factors, activity level, and your goals. This will help prevent muscle loss and keep your metabolism ticking over (5).
Depending on the type of fasting you’re doing, spread the calories out over the course of your eating window in 2-4 meals.
If you’re not sure how many calories you need, there are plenty of online calculators that can help you out.
Another option is to use the hand-size method. This involves eating one palm-sized portion of protein, one fist-sized portion of vegetables, and one cupped-hand portion of carbohydrates at each meal.

Hunger after a fast is completely normal, but eating too much can quickly offset any weight loss you’ve achieved. This is another common mistake that people make when they start intermittent fasting.
The hormone ghrelin is responsible for making you feel hungry, and it’s also responsible for increasing your appetite after a fast. When you overeat, ghrelin spikes and makes you even hungrier than you were before. This can quickly lead to weight gain and stalled progress (2).
Overeating negates the benefits of IF and can lead to weight gain. It also makes it harder to stick to your fasting plan in the long run.
Start by eating a small, nutritious meal when you break your fast. This will help stave off hunger without overeating. Here are some nutritious, filling meals you can use to break your fast:
You can also try drinking a glass of water or herbal tea before meals to help you feel more full.
And if you’re still struggling, try eating more protein- and fiber-rich foods. These nutrients are known for their ability to help control hunger and promote satiety.
If you’re still feeling hungry after your first meal, wait 20-30 minutes before having a second. This will give your body time to register that it’s full.

The eating window is the time when you’re allowed to eat whatever you want. And while there are no rules about what you can and can’t eat, some foods are better than others.
Ultra processed junk food, sugary drinks, and refined carbs will spike your insulin levels and contribute to weight gain. On the other hand, whole foods like vegetables, whole grains, lean protein, and healthy fats can help you lose weight and improve your health (1).
Eating processed junk food negates the benefits of intermittent fasting and can lead to weight gain. It can also contribute to other health problems, like diabetes, heart disease, and high blood pressure (1).
Furthermore, your body responds differently to whole foods and highly processed foods. Whole foods are digested more slowly, which means they don’t cause the same spike in insulin levels as highly processed foods do. Whole foods can help you lose weight and improve your health (1).
Eliminate ultra processed junk food from your diet and replace it with whole foods. Here are some healthy, whole foods you can include during your eating window:
Here are some foods that you should avoid:
Water is essential for weight loss, regardless of whether you’re fasting or not. Drinking plenty of water while fasting helps you feel fuller and less prone to cravings. Furthermore, your body functions better when it’s well hydrated (4).
Not staying hydrated can lead to dehydration, which can cause a slew of health problems. These include (7):
Furthermore, dehydration can make it harder to lose weight. This is because water helps to flush out toxins and keep your metabolism working properly.
Drink at least 8 glasses of water a day, especially during your fasting periods (7). You can also drink other beverages like unsweetened green tea or herbal teas.
While unsweetened black coffee is okay in moderation, caffeine can dehydrate you. So make sure to drink an extra glass of water for every cup of coffee you have.

Many people don’t understand what a clean fast means. A clean fast, which is what you’re expected to do during your fasting window, means not consuming anything but water, black coffee, and unsweetened tea.
It’s important to be aware of what you’re drinking during your fast because many common drinks contain hidden calories and carbs.
Foods that are close to zero calories or labeled “diet” or “zero-calorie” are often full of artificial sweeteners, some of which can break your fast.
Consuming anything other than water, black coffee, and unsweetened tea during your fasting window can break your fast and negate the benefits of intermittent fasting. This can lead to frustration and discouragement, and may even cause you to give up on intermittent fasting altogether.
Furthermore, some of the benefits of fasting such as ketosis and autophagy only occur after an extended period of time without food (5). So if you’re constantly breaking your fast, you may never experience these benefits.
If you’re not sure whether a drink is allowed during your fast, check the ingredients list. If it contains any sugar or artificial sweeteners, it’s best to avoid it.
Look out for products containing:
Whether you’re trying to lose weight or improve your health, exercise is important. Exercise helps to increase your metabolism, burn calories, and improve insulin sensitivity. All of these things are beneficial for weight loss and improved health (3).
If you’re not exercising while intermittent fasting, you’re missing out on some of the benefits of fasting. Exercise helps to increase your metabolism and burn calories, both of which are necessary for weight loss (5).
Muscle loss is also a common problem among people who fast. This is because when you’re fasting, your body starts to break down muscle tissue for energy. This can lead to a loss in muscle mass and a decrease in your metabolic rate (9).
Having a strength training routine can help prevent this and may also build muscle, which can help you lose weight in the long term (9).
Intermittent fasting is not an excuse to avoid exercise. In fact, exercising while fasting can help you burn more fat and improve your health.
Aim for at least 30 minutes of moderate-intensity exercise most days of the week. This could include walking, biking, swimming, or light weight training.
If you’re new to exercise:
Getting enough sleep is important for both your physical and mental health. Not only does it help you recover from exercise, but it also helps to regulate your appetite.
When you don’t get enough sleep, your body produces more of the hormone ghrelin. This hormone increases your appetite and makes you crave high-calorie foods (8).
Not getting enough sleep can also lead to weight gain. This is at least partly because it can disrupt your body’s ability to regulate blood sugar and insulin levels (8).
Aim for 7-9 hours of quality sleep per night (8). If you have trouble sleeping, try some of these tips:
Weight loss is a slow process. It can take weeks or even months to see results. This can be frustrating, especially if you’re used to seeing results quickly.
Even if you’re not getting into IF for weight loss, most of its benefits come with time.
When you’re not getting the results you want, it can be tempting to give up. This can lead to yo-yo dieting and weight gain.
Yo-yo dieting is a cycle of losing and gaining weight. It’s dangerous for your health and can make it harder to lose weight in the future.
The frustration when you’re not seeing results fast enough can also lead to making other mistakes, such as not eating enough or overdoing it with exercise.
Be patient and give your body time to adjust. Remember that weight loss is a slow process and can take weeks or even months to see results.
Focus on other potential benefits of intermittent fasting, such as improved mental health, energy levels, and digestion (5).
If you’re struggling with your weight, seek professional help. A dietitian or nutritionist can help create a plan that’s right for you and help you stay on track.
Intermittent fasting can be a great way to lose weight or potentially improve your health, but it’s not for everyone.
There are a few mistakes that people often make when they start intermittent fasting. These include not eating enough, overdoing it with exercise, and not being patient.
If you’re thinking about starting intermittent fasting, be sure to do your research and talk to your doctor first. Once you start, be sure to focus on the benefits and stay patient. It can take time to see results.
