When Intermittent Fasting Stops Working: Reasons, Solutions, and Effectiveness

Recently, intermittent fasting has become more well-liked as a technique to reduce weight, enhance general health and longevity, and even improve mental clarity. Yet, there are several situations where intermittent fasting may not be effective for everyone or may cease to be effective after a while. In this post, we’ll look at when intermittent fasting might not be a good idea, how to solve it, and its potential effectiveness.

Intermittent fasting: What is it?

Fasting and non-fasting phases are alternated during intermittent fasting (IF), a dietary strategy. It focuses more on when to eat them than than what foods to eat. The most typical IF strategies include:

  • The 16/8 approach entails skipping breakfast, limiting eating to 8 hours (for example, from 12 to 8 pm), and then fasting for 16 hours.
  • The 5:2 diet entails eating regularly for five days and limiting calories to 500–600 on two separate days each week.
  • Alternate-day fasting: This entails abstaining from all or nearly all calorie-containing foods on fasting days.

Why an Intermittent Fast May Not Be Successful

Although while intermittent fasting has many health advantages, it might not be effective for everyone or it might lose its effectiveness for some people over time. The following justifies why intermittent fasting could not be effective:

  • Even while intermittent fasting can help you eat less, if you take in more calories than you expend, you won’t lose weight. This is because you are not in a caloric deficit. Regardless of the diet strategy you use, you must be in a calorie deficit to lose weight.
  • During the dining window, you are consuming too many calories. Consuming excessively within the meal window is not permitted by intermittent fasting. You won’t lose weight if you consume too many calories during the eating window.
  • You lack consistency. When it comes to intermittent fasting, consistency is crucial. Progress might be hampered by skipping fasts or bingeing during the eating window.
  • Sleep deprivation can cause increased hunger and overeating, making it more difficult to adhere to the eating window.
  • You suffer from a chronic medical problem. It may be more difficult to lose weight with any diet, including intermittent fasting, if you have certain medical disorders including insulin resistance, thyroid issues, or PCOS.

Can Intermittent Fasting Work for Everyone?

Although it’s not a one-size-fits-all strategy, intermittent fasting can be an effective weight loss method for many people. Others may find it simple and efficient, while others may find it difficult to keep with or not produce the desired outcomes.

For those who can maintain a regular eating schedule and are in a calorie deficit, intermittent fasting may be beneficial. Having a set eating time can be helpful for people who struggle with self-control when they nibble or graze throughout the day.

Unfortunately, not everyone will benefit from intermittent fasting. For those who have a history of disordered eating, it could be upsetting or even detrimental to their mental health. Also, before attempting intermittent fasting, persons with diabetes, those who are pregnant or nursing, and those who are taking specific medications may need to speak with a healthcare professional.

Intermittent fasting’s efficiency

When coupled with a good diet and regular exercise, intermittent fasting can be a powerful weight loss tool. According to studies, intermittent fasting can significantly reduce body weight and body fat while also improving inflammation, blood sugar regulation, and cholesterol levels.

But, individual characteristics including age, sex, starting weight, and general health may affect how beneficial intermittent fasting is for a particular person. It’s crucial to remember that results may vary and that weight loss with intermittent fasting is not guaranteed.


Although intermittent fasting may not be effective for everyone, it can be a beneficial technique for losing weight and enhancing general health. If you’re not losing weight with intermittent fasting, it’s crucial to assess your caloric intake, consistency, and sleeping patterns. If you suspect an underlying medical concern, you should also speak with a healthcare professional. While some people find success with intermittent fasting, it’s crucial to put your entire health and wellbeing before weight reduction objectives and to pick the strategy that will work best for you.
