What would happen if you did not eat anything, except potatoes?

What happens if you eat only potatoes? Martian is one of the steps that were noted in 2015. This science-fiction film in which Matt Damon played an astronaut who was stuck on Mars without food, except for a hoe, made people think about many things.

In fact, some people tried to repeat the experience that the main character had. For example, an Australian (aged 36) decided to participate in the same diet from this film.

Andrew Taylor is trying to lose weight with the help of the diet of Mars. His goal is to eat potatoes and nothing more during the year. But is it possible for people to live a normal life if they only eat potatoes? Are there any other products that he could use instead of potatoes.

After one month of this odd diet, Andrew shared a photo in his profile on Facebook, which shows a plate half filled with mashed potatoes. It seems that this is a good example of the so-called sensory-specific saturation. In other words, people tend to lose interest in any type of food as soon as they start to eat more, and when they feel this feeling of satiety, they consume less.

Mr. Taylor obviously enjoys the benefits of this weight loss program because he lost about 22 pounds (10 kg) in 30 days, and he also increased his energy levels. In addition, this diet has reduced the risk of developing diabetes and other similar diseases. But the real question is, what can he expect in the long run.

What would have happened if you had not eaten anything, but the potatoes

A sufficient amount of fat and protein?

Consuming 6.6 pounds (3 kg) of potatoes a day will give you about 2000 calories, which is a good amount of calories for an average person, such as Andrew, to lose weight. However, despite the fact that potatoes are packed with fiber and carbohydrates, it is very difficult to use only potatoes to get protein. A person who has 120 kilograms should take 90 grams of protein a day, but this diet can only get him 2 ounces (60 grams).

Proteins consist of many different types of amino acids, and some of these amino acids come from the food we eat, and the potatoes include very good harmony between them. However, despite this harmony, the potato can not get us enough amino acids.

In addition, their fat content is also very low (about 0.3 ounces / 9 g at 6.6 lb / 3 kg). In other words, this diet does not provide two very important fatty acids – linoleic acid and linolenic acid, and in addition, it does not contain enough fat to maintain proper intake of vitamin K, E, D and A,

People are encouraged to consume foods containing long-chain fatty acid omega-3, and experts recommend for this purpose fatty fish. The fact is that these special fats have special functions in cell membranes; They can help stabilize blood pressure and serve as hormones.

Health Benefits of Sweet Potatoes

Minerals and vitamins

There is no doubt that Andrew Taylor gets enough niacin, thiamine, folate, vitamin B6, potassium, vitamin C, copper, phosphorus and magnesium, despite the fact that many of these nutrients are lost during the standard culinary procedure. In addition, he improved the intake of vitamin E and vitamin A, calcium and iron by introducing sweet potatoes into the menu. However, his unusual diet does not provide enough vitamin B12 and vitamin D.

Some experts note that the sunny weather in Australia can provide enough vitamin D, but it will not have enough vitamin B12 after one year for proper functioning if it does not include an additive in its diet. Prolonged absence of vitamin B12 in the body leads to pernicious anemia and even to long-term nerve damage. Andrew includes certain seasonings in his diet, so the use of a yeast extract is an ideal option to increase the level of other B vitamins, such as B2 and biotin. Deficiency of these vitamins can lead to a decrease in the ability to use energy from potatoes.

In addition, this special diet will give him about 6 mg of zinc, which is 30% less than the recommended 9.5 mg per day. The lack of zinc in the system will become noticeable rapid in some tissues with a rapid turnover, as in the intestine or lining of the skin, which ultimately leads to weakening of immunity, healing of wounds and even damage to taste buds.

There is also the opportunity to test the deficiency of other minerals, including selenium, chloride and iodine, and the amount of these minerals in potatoes is closely related to the quality of the soil. Using salt, enriched with iodine, it will meet the requirements of iodine and chloride, but in the diet there will still be no selenium. In other words, he may experience impaired immunity and a very weak reproductive function and a negative effect on thyroid function.

A little experiment with potatoes for girls will change the way to think about food

Is there anything better than a potato?

Consuming only one type of food will probably not lead to negative consequences, but only when it comes to short-term experiments. But scientists have not yet found food that could provide all the minerals, vitamins and nutrients necessary for adults. On the other hand, Andrew Taylor made a firm decision that he will continue to practice this potato diet. This means that this diet is good, like almost any other diet based on one food.

In fact, potatoes are supplied with many other amino acids, minerals and vitamins compared to starchy foods such as rice and pasta. If he followed a diet based on animal feed from a single source, he would miss the fiber, and he will not have enough minerals, vitamins and antioxidants in his body. Finally, fruits and other non-starchy vegetables are not rich in fats and proteins, so he would have to eat many of these foods to get enough.

There are situations when the green color is not very healthy

It is also good to note that potatoes create solanine, a strong poison belonging to the family of glycoalkaloids. The amount of this substance in commercial potatoes is very low, but potatoes that have been stored under the influence of sunlight or damaged potatoes can turn green and lead to increased production of solanine. Taking even a small amount of green potatoes can lead to vomiting, nausea, migraine, dizziness and fever.

Scientists have not yet found the exact amount that can be considered toxic, and we do not know how the human body absorbs and processes the solanine, or where this poison ends when it is consumed in small amounts for a long period of time. Obviously, it is completely safe to consume a relatively normal amount of potatoes (10 ounces / 300 g. Maximum) every day.

However, science still has no answer as to how the organism will react when it is exposed to large quantities in a year. However, Andrew Taylor should find peace in the fact that these vegetables are regularly eaten in many kitchens and they are part of the standard diet in many cultures, although people eat many other foods along with potatoes.


Without any doubt, after a diet that includes only one food, is not a wise choice; However, this does not mean that we must include a wide range of products in our diet. Previously, people did not have access to exotic products that we can now consume. Their diet consisted of only 5-10 kinds of products. However, many of them lived for a very long time, and they were quite healthy. Food should be considered as a source of energy, and not something that can entertain us when we are bored.
