Why Is Intermittent Fasting Not Working For Me?

Many people swear by intermittent fasting as a way to not only lose weight but feel better by doing it! However, now that you’ve made the jump, you’re not seeing the same results, leaving you to question why intermittent fasting isn’t working for you.

Well, to be blunt – you’re probably not doing it right. But that’s okay! Here are five of the most common reasons intermittent fasting may fail. Once you identify what you’re doing wrong, you can quickly adapt and get on the right path to a healthier you!

Key Takeaways

  • Eating too much during your eating windows can sabotage your intermittent fasting efforts. Binge eating after a fast may lead to consuming more calories than intended, hindering weight loss progress.
  • Conversely, not eating enough calories can also impede your results. Ensure that your meals during eating windows contain adequate protein and fiber to keep you satiated and provide essential nutrients.
  • Staying hydrated is crucial during intermittent fasting. Dehydration can slow down your body’s natural processes, similar to not eating enough food. Drinking water, tea, black coffee, or seltzer water can help curb hunger cues and support your fasting journey.
  • The duration of your fasting windows plays a role in the effectiveness of intermittent fasting. If you’re not seeing results, consider lengthening your fasting period to allow your body to tap into its fat and energy stores.
  • Consistency is key. Even small slips or deviations from your intermittent fasting plan can impact your progress. It’s important to resist cravings and distractions, sticking to the fasting schedule to achieve desired outcomes. Patience and adherence to the fasting regimen will help you get back on track.

You’re Eating too Much

Technically during your eating windows, you can eat whatever you want without restriction. You don’t have to limit the types of food or number of calories – and that freedom, especially after a fast, can be dangerous!

After your fasting window, you may feel ravenous, so much so that you start to binge eat. While it may feel good in the moment, you’ll feel bloated, lethargic, and queasy later on. That binge eating pattern may extend throughout the day and not just during the first meal after fasting, causing you to eat more than your daily calorie intake if you’re not careful.

You’re Not Eating Enough

On the flip side, you may not be eating enough calories. Your body needs enough energy and fuel to power its base activities. If it doesn’t get it, your body will start to slow down these activities to preserve energy. That can cause a plateau in your weight loss journey, so it will seem like intermittent fasting isn’t working.

When you’re eating, make sure to focus on foods that are high in protein and fiber. Look for things that will make you feel fuller longer and that are high in nutritional value. These don’t have to be high calorically if you still want to watch what you eat.

You’re Not Staying Hydrated

Water is safe to drink during intermittent fasting, so it’s important to stay hydrated. If you don’t, it may slow the body’s natural processes, just as not eating enough food will. You do not want to get dehydrated during intermittent fasting.

Too, water can help starve off some of the hunger cues, helping you weather your fasting windows with ease. If plain water isn’t your preference, you can always try tea, black coffee, or seltzer water. Some intermittent fasting plans will allow you to add no-calorie sweeteners to your drinks, while others don’t, given they can cause a metabolic reaction.

You’re Not Fasting Long Enough

You need to find an intermittent fasting plan that works for you, so if you’re not seeing results, you may need to adjust the plan to fast longer. You want to fast enough that your body is forced to use its fat and energy stores, and if you eat before it taps into that, you won’t see the same results.

If you have shorter fasting windows, it will take longer for you to see results. They will be more gradual, so you may not even notice them at first. Intermittent fasting isn’t a quick fix, but you do need to fast long enough to make a difference in your body’s metabolic rate.

You’re Not Actually Intermittent Fasting

Intermittent fasting can be hard, especially when you’re just starting out. If you have a slip, no matter how small, it will impact the results you see. If you find yourself craving some food, grab an approved drink instead. Go for a walk. Do something to distract yourself.

It’s human nature to want to do the only thing that you’re not allowed to do but resist the urge. You’ll feel all the better for it.

So, Why Isn’t Intermittent Fasting Working for Me?

There could be any number of reasons why you’re not seeing the results you desire from intermittent fasting; however, be patient, take a step back, and evaluate your patterns. If you adhere to the strict fast, you will get back on track.


  • What is intermittent fasting?

Intermittent fasting is an eating pattern that cycles between periods of fasting and eating. It doesn’t specify which foods to eat but rather when to eat them.

  • How does intermittent fasting work for weight loss?

Intermittent fasting can promote weight loss by creating a calorie deficit. During the fasting periods, your body utilizes stored fat for energy, leading to fat loss over time.

  • Is it necessary to count calories during intermittent fasting?

Intermittent fasting doesn’t require calorie counting, but it’s important to be mindful of your overall calorie intake during eating windows to avoid overeating or undereating.

  • Can I eat anything I want during eating windows?

Technically, you can eat any type of food during eating windows. However, for better results and overall health, it’s recommended to focus on nutrient-dense foods such as lean proteins, fruits, vegetables, and whole grains.

  • Can I drink water or other beverages during fasting periods?

Yes, it’s essential to stay hydrated during intermittent fasting. Water, tea, black coffee, and seltzer water are generally allowed, but be cautious with adding sweeteners, as some plans discourage their use due to potential metabolic reactions.

  • How long should I fast during intermittent fasting?

The duration of fasting depends on the specific intermittent fasting plan you follow. It can range from 16 hours of fasting with an 8-hour eating window (16/8 method) to longer fasting periods like alternate-day fasting or extended fasting. Adjusting the fasting duration may be necessary if you’re not seeing desired results.

  • Can intermittent fasting be suitable for everyone?

Intermittent fasting may not be suitable for everyone, especially those with certain medical conditions or individuals who are pregnant, breastfeeding, or have a history of disordered eating. It’s recommended to consult with a healthcare professional before starting any new dietary approach.

  • What if I accidentally break my fast during intermittent fasting?

It’s common to face challenges and slip-ups during intermittent fasting. If you accidentally break your fast, acknowledge it and continue with your fasting schedule. Consistency over time is more important than occasional deviations.

  • How long does it take to see results with intermittent fasting?

The timeline for seeing results varies for each person. Some individuals may notice changes in their weight or energy levels within a few weeks, while others may take longer. It’s important to be patient and evaluate your progress over an extended period.

  • Can intermittent fasting be combined with other dietary approaches?

Intermittent fasting can be combined with various dietary approaches, such as the ketogenic diet or a balanced macronutrient plan. However, it’s crucial to ensure that the combined approach aligns with your health goals and is sustainable for your lifestyle. Consulting a healthcare professional or registered dietitian can provide personalized guidance.
