When you are not maintaining a healthy diet, there are many common side effects that you can expect. Unhealthy diets commonly lead to weight gain, but there are many other unfortunate side effects that you may not expect to incur. From canker sores to acne, an unhealthy diet can wreak havoc on your well being. Even as you begin celebrating the holidays, it is important to keep tabs on your health. In this article, we will share a few unwanted and unexpected side effects of an unhealthy diet.

1. Exhaustion

If you are not getting the proper nutrients needed to support your lifestyle and activity level, you will experience exhaustion. Vitamin B12 and Vitamin D help support the energy that your body needs to be alert and productive. Not only will overeating unhealthy foods make you exhausted, but undereating will deplete your system. When you don’t take in enough calories to compensate for your daily activity, you will feel depleted.

2. Canker Sore

Many people do not recognize that a canker sore can be caused by a negative diet. These sores can be caused by vitamin deficiencies and foods that have high levels of citric acids. When you are eating improperly, you will likely experience a high level of vitamin deficiencies. When you are consuming a large amount of citric acid from foods like cheese, you may begin feeling these sores pop up. Thankfully, there are now laser treatments available to remove these unwanted sores. After you receive laser treatment, optimize your diet to prevent them from appearing again in the future.

3. Acne

When you eat a diet that is high in sugar, you will likely see acne appear on your face, back, and chest. When your blood sugar elevates at a rapid pace, the oils in your skin respond negatively. If you commonly struggle with acne on the skin, consider pursuing a diet that is composed of foods that have a low-glycemic index. Although your skincare routine helps prevent acne, so do your dietary decisions.

4. Brain Fog

As you know, eating poor foods can cause your body to feel sluggish. Not only will your body move slowly, but your brain will not be functioning at an optimal pace. From low attention capacity to impaired cognitive function, brain fog can affect your ability to be productive in your professional and personal life. Some foods that are specifically known for hundering brain functionality are:

  • Alcoholic beverages
  • Dairy
  • Processed foods and meats
  • Peanuts

As we mentioned earlier, Vitamin B12 is an important component of your overall health. This vitamin has a great impact on your body and brain. To improve your brain health, eat foods that contain adequate levels of B12.


The side effects of an unhealthy diet go far beyond weight gain; they also affect the abilities of your brain and your body. When you are unable to process information properly, you will suffer consequences at home and at work. When you have canker sores and acne, you will feel physically out of touch with your body. Use this information to take the necessary steps to improve your diet and well being.
