Can Anxiety And Stress Cause Weight Loss?

Anxiety and stress go hand in hand. It is very hard to experience one without experiencing the other. When it comes to weight, both these emotions can cause weight gain and weight loss. Let us look at how they can cause one to lose weight.

  • Lack Of Eating

One way anxiety and stress are known to cause weight loss is by causing one to be less interested in food (7). Weight loss requires you to take in fewer calories than your body needs. If you do so, you create a calorie deficit, which then causes weight loss. When you are stressed, you start to lose your appetite because of all the things going through your mind. You start to feel less hungry, and when you eat, you won’t eat as much as you used to. It is not easy for one to realize how much they are starving themselves, and this can unconsciously cause a massive loss of weight. 

Apart from being disinterested in food, anxiety and stress can easily make you forget to eat. Let’s say what is stressing you is work, and you are anxious if you get your job done in time, or it may result in you losing your job. This will lead you to miss so many meals while trying to finish work in time and thus would result in weight loss. One can easily adopt unhealthy eating habits, so you should try to eat normally even when stressed.

  • Nervous Movement 

When people are anxious or stressed, they are always moving. They are restless, pacing around, fidgeting, or making other movements (6). One way a person can lose weight is by doing exercises. Cardio is an example of exercise one can do to lose weight, and walking is part of cardio. These people, hence, end up burning calories with their constant movement and would result in weight loss.

  • Exercising To Distract Themselves 

One way of dealing with stress and anxiety is by either doing an activity that one loves or exercising. If the activity you love is exercising or workout to manage these emotions, then you are likely to lose weight. People with anxiety sometimes exercise because working out produces the feel-good hormone that makes one happier, hence better moods. 

Working out can help one lose weight when incorporated as part of an intentional healthy weight loss plan. However, unintentional weight loss due to anxiety because of excessive exercise or any of the other reasons listed here can be dangerous.

Before you get into an exercise program, it is always important to consult an expert.

  • Insomnia 

Lack of sleep or insomnia is one of the symptoms associated with stress and anxiety. People experiencing these emotions are usually restless and have a hard time sleeping, if they sleep, it isn’t long enough (6). When you have insomnia, your body does not produce the right amounts of cortisol. It is a hormone related to stress. Production of this hormone affects your metabolism. You have a faster metabolism, and since you are not eating, it results in weight loss. 

The fact that you are awake means your body needs more energy than it would require if you were asleep. This makes your body dig into your energy reserves to provide itself with the energy it needs, this may lead to weight loss. Even if you are stressed, your body needs to rest and you should try to sleep. If you are still finding it hard to sleep, you should consult an expert. They might prescribe sleeping pills or offer other ways of getting sleep. It may be harmful to try unprescribed sleeping pills, so you should not try to do that.

  • Production Of Stress Hormones 

When you have anxiety or stress, your body goes into a mode of fight or flight. This mode is also referred to as acute stress response, and it is your body’s way of responding to the thing causing you stress or anxiety. When it is in this state, your body produces adrenaline and cortisol. These hormones help you react and stay alert during stressful, dangerous, or unknown situations. The problem with these hormones is that they come with side effects. 

Adrenaline prepares your body for a vigorous physical activity like running away or fighting. This hormone also reduces your appetite (4). When you don’t have an appetite, you will consume fewer calories than your body needs and will help promote weight loss. Adrenaline also causes a faster heartbeat and breathing, and this helps burn more calories.

On the other hand, cortisol is responsible for minimizing some body functions that may seem unnecessary during a stressful occurrence. Some of the body functions that are usually suppressed are digestive, reproductive, and immune function, among others. When digestion is stopped or minimized, it means your body is not absorbing nutrients and might be discarded as waste. This could lead to weight loss since you are not able to digest and absorb food, hence creating a calorie deficit.

  • Stress Causes Gastrointestinal Distress

Another thing that causes one to lose weight is distress in the gastrointestinal system. Stress affects most of the parts of the GI system. It causes symptoms like (5, 11):

  • Abdominal pain
  • Gas 
  • Abdominal bloating 
  • Feeling of nausea and vomiting 
  • Heartburn 
  • Reduced appetite 
  • Constipation 
  • Diarrhea 
  • Pain while swallowing food

All the symptoms shown above will affect a person’s eating habits and may result in them eating less. This would then result in weight loss since it creates a calorie deficit.

  • Anxiety Medicine Can Cause Weight-Loss

When one is experiencing serious anxiety, they are usually given pills to help them deal with it. Some of those pills have side effects that can cause weight loss.

Here are some of the drugs and how they cause weight loss:

  • Benzodiazepines. This drug acts as a central nervous system depressant. Among the side effects of this drug are nausea, vomiting, and stomach upset (2). These side effects can easily lead to weight loss. 
  • Venlafaxine and Desvenlafaxine. These two drugs are likely to lead to a decrease in one’s appetite, hence triggering weight loss (2).
  • Buspirone. This drug is known to cause very many gastrointestinal side effects like diarrhea, nausea, vomiting, stomach pain, and others (2). These side effects can lead to weight loss.
  • Monoamine oxidase inhibitors. These drugs also have gastrointestinal side effects, which can cause weight loss. Another thing is that they come with dietary restrictions (2).

Can Anxiety and Stress Cause Weight Gain?

As previously mentioned, anxiety and stress can also cause weight gain.

Here are some ways these two emotions can cause weight gain:

  • Cravings for unhealthy foods (8, 10). Some people crave foods like chocolates, pizza, fries, and more unhealthy foods while stressed. These are high-calorie foods, and regular consumption of these foods is likely to cause weight loss. 
  • Lack of sleep. Some people, when they can’t sleep, will always find themselves snacking at night (5). This snacking at night can cause weight gain since you are eating. On top of that, you are not going to be burning the calories you ate since it’s at night, and your body is inactive. This often leads to weight gain.
  • Reduced motivation to do anything (5). People who are stressed find themselves tired most of the time and would just be lethargic. Lack of physical activity can lead to weight gain since you are just eating and lazing around without doing anything that would help burn the calories you’ve consumed, resulting in weight gain.
