Weight Loss Tips: 8 Signs Intermittent Fasting Isn't For You

Intermittent fasting: constant headaches can be a sign that you should not follow intermittent fasting

Intermittent fasting is a type of eating that alternates between regular meals and fasting. According to studies, intermittent fasting can help control weight and can even help reverse some ailments. For many years, people have used fasting to reduce their weight and for other purposes. But like many other restrictive diets, there are also some drawbacks to this diet pattern. In some circumstances, intermittent fasting can do more harm than good. In this article, we outline the circumstances in which intermittent fasting should be absolutely avoided.

Weight Loss Tips: Signs You Shouldn’t Intermittently Fast

1. Feeling irritated or angry

The rage caused by hunger is, without a doubt, a real sensation. When you can’t eat when your body tells you it’s hungry, you get this heartburn feeling, moodiness, or general irritability. It takes some experience for your body to get used to going 16 hours without eating, and some people’s bodies may never be content with eating within a restricted window.

2. Severe headaches

The common negative effect of intermittent fasting is headaches. They usually occur in the first days of a fasting strategy. According to one study, “fasting headaches” often occur in the frontal lobe of the brain and are mild to moderate in their discomfort.

3. Trouble sleeping

The ability to operate cognitively, maintain emotional stability, and recover and regenerate muscles after exercise all depend on getting adequate sleep each night. Since eating before bed keeps your brain active and makes your body restless, it can be difficult for your body to relax and fall asleep.

4. Irregular periods

Unexpected weight loss is another secondary consequence of intermittent fasting. Women who lose weight drastically or who continually don’t eat enough calories each day may notice that their menstrual cycles slow down or possibly stop altogether.

5. Sensitive gut

An upset stomach can result from any diet if you don’t get enough beverages, vitamins, protein, or fiber. If you already have digestive problems, intermittent fasting can make them worse. The prolonged fasting intervals associated with IF could possibly worsen digestive problems. Fasting periods can disrupt the normal functioning of the digestive system and cause bloating, heartburn, and constipation.

6. Blood sugar problems

The last thing people with diabetes need is fasting to compound the many highs and lows in blood sugar they already experience on a daily basis. The combination of intermittent fasting and diabetes medications can result in dangerously low blood sugar levels. You can get hypoglycemia from intermittent fasting, which is problematic if you have thyroid or insulin issues.

7. Weak immunity

People who have recently recovered or are now battling serious illness should not engage in intermittent fasting without first seeking a doctor’s approval. Most of the time, adequate calorie intake is necessary to preserve lean body mass and a functioning immune system, which is crucial for those who are ill or have weakened immune systems.

8. History of eating disorders

Since intermittent fasting has a high association with bulimia nervosa, people who are at risk of eating disorders should not adhere to any fasting-related regimen. Perfectionism, impulsiveness, mood instability, and having a family member with an eating problem are risk factors for developing an eating disorder.

We can lose weight with intermittent fasting, which can also help with a number of conditions. However, it is not a long-term remedy for these problems. It is not advisable to adopt a restrictive diet such as IF as a permanent way of life.
