A high-protein diet is a very popular way to lose weight. Many people believe that eating high-protein foods will help them lose weight faster and gain muscle mass. But there are many side effects of this type of diet, which can be harmful to your health. In this article we will discuss 5 major side effects of high-protein diets:

1. Lowers Digestive Health

  • Lowers Digestive Health

High-protein diets can cause a lot of digestive problems: constipation, diarrhea and bloating acid reflux, and flatulence (gas). Heartburn is another side effect that you should know about when you start the high-protein diet.

Your digestive system will be affected by the high amount of food you consume on a daily basis which may lead to symptoms like indigestion or nausea if they occur regularly over time.

2. Increases The Risk Of Cancer

  • Increases The Risk Of Cancer

Proteins are made of amino acids, which are the building blocks for all proteins in your body. They’re also broken down into glucose, which can be converted into energy for cells and organ systems to function properly.

Glucose is the primary source of energy for many organs and cells in our bodies—including those involved with cancer growth!

This means that if you eat a high-protein diet over many years, your risk of developing cancer increases significantly due to increased consumption of glucose from this source (this is why “high-carbohydrate diets” have been linked with lower rates of various cancers).

3. Causes Vitamin and Mineral Deficiency

You may be wondering how a high-protein diet can cause vitamin and mineral deficiency. Well, it’s not just about the amount of protein you eat; it’s also about what kind of proteins you’re consuming.

Proteins are made up of amino acids (the building blocks). Some proteins are incompletely digested and absorbed by the body, which means they don’t add many benefits to our health.

These include whey protein powder, cottage cheese, and other forms that come in powder form or granules. They’re usually high in lactose because they were made using milk solids as their base ingredient.

Other types of foods—such as eggs, meat, and fish—contain all 20 essential amino acids required by your body for optimal function. This means that these foods can help prevent illness if eaten regularly over time without causing any damage to your overall health status

4. Dehydration & Kidney Stone

If you are on a high-protein diet, it is very important that you drink enough water. When your body loses too much water, it can lead to dehydration and kidney stones.

Kidney stones are painful because they block the passage of urine through the kidneys and bladder. The best way to avoid this condition is by drinking plenty of fluids every day.

If you do not drink enough water on a regular basis (especially as part of an intense workout program), then there’s a good chance that your body will become dehydrated over time—and this may cause problems with urination or incontinence in some cases!

5. Lowers Thyroid Function

You might have heard that the thyroid is a small gland in the neck that produces hormones that affect how your body uses energy, how it stores and burns fat, and how it controls the rate of certain chemical reactions in your body.

When you’re on a high-protein diet, this can lead to low levels of thyroid hormone production. This can have some major side effects:

  • You’ll feel tired all the time
  • Your metabolism will slow down (and therefore burn fewer calories)
  • Your muscles may become less strong or lose their tone
