Many people believe that starving or strict diets will help them lose weight, which is not true at all because metabolism has its own logic of eating. If you don't convince your body that there is always enough food available, you won't lose weight either. In cases of starvation, the body will be even more thrifty with fats and send you all kinds of signals that it won't deplete the reserve fats (those fats you'd rather get rid of) because even worse times may come.

This puts you in a vicious cycle where there is no diet in the world that can convince the body otherwise. Therefore, it is very important to know the symptoms that tell you your body lacks fats.

You're always hungry
Hunger can be a result of too many carbohydrates and not enough fats. The fact is, carbohydrates are processed in the stomach in half an hour, so their energy impact fades quickly, while fats provide energy to the body for 4 hours. If you are always hungry despite normal eating, it's time to treat yourself to some full-fat yogurt or cheese.

You're mentally tired
One of the conservation measures is for the body to slow down brain function, which normally consumes 70% of all energy. This can make you feel mentally tired, irritable, have difficulty concentrating... Typically, this indicates a deficiency in omega-3 fatty acids, so eat more fish, spinach... it won't make you gain weight, you'll just feel better.

Dry skin and acne
One of the most obvious signs of a lack of fats is dry skin. Sebum is a type of fat that forms a thin protective layer on the skin and keeps it adequately moisturized. Problems with sebum secretion are best known to teenagers when clogged sebaceous glands cause adolescent acne. So pay attention to your skin as well. Having more pimples is not a good sign.

You're always cold
Fats in the body also ensure that you have a constant and stable body temperature. Insufficient fats, even if fats are part of an extreme body conservation measure, will make you feel cold when everyone else around you is warm.

Pain throughout the body
When the body utilizes all the signals mentioned above and maybe a few more, the last and extreme one follows. You will feel pain in the joints, muscle aches, headaches... A lack of fats also means a lack of joint lubrication, which can lead to serious injuries.
