Keto, the Carnivore diet and other restrictive diets are popular, because they work frequently. People adopt the diet and see results, sometimes dramatically, albeit often at short notice. [196590] 05] "Does he / she not look great?" But my question as a registered nutritionist is "Yes, but how do you feel ?"

You see Restrictive diets – or diets that you need to eliminate foods or nutrient groups – can have a negative impact on your brain.

Here are three that I often see in my work with clients.

. 1 Increased desire can become compulsive.

Tell someone he can not eat peanut butter (Ahem, Paleo) and that he's more into peanut butter. Tell them they can only eat a few greasy carbohydrates a day (um, keto), and suddenly every pizza with a frozen dish, bowl-o-pasta and loaf of bread looks even more delicious.

"It's an inherent behavior in humans," says Brierley Horton, a registered nutritionist in Birmingham, AL. "It's like the child who is told that it's not possible to touch or touch anything, and that's all they want to do, and then usually done with it. Tell me I can not eat carbohydrates and suddenly I see carbs everywhere and that's all I'm thinking about. "

Some people will tell you that the craving of your body calls you the nutrients it needs. These people are wrong. No clinical research has ever shown that this old diet chestnut is true.

"Craving is not based on nutritional needs, it's based on depriving yourself," says Horton.

. 2 By cutting food groups, the brain takes the necessary nutrients.

Take carbohydrates again. Carbohydrates provide your brain with glucose, a fuel needed for basic tasks to complex tasks. About a decade ago, as low-carb diets gained in popularity, researchers looked at the effects of carbohydrate deficiency on the mood of dieticians. Sure, the study participants who consumed the few carbohydrates reported a worse overall mood than those on a carbohydrate diet.

And not only the brain is deprived. Carbohydrates are not just processed products like pizza and white bread. These include whole grains, vegetables and fruits. And if you do not eat these foods, you will miss fiber, antioxidants, and other essential vitamins and minerals that keep the body functioning and performing at peak performance.

. 3 Accurate monitoring of nutrients can lead to eating disorders.

Research has shown that restrictive diets or elimination diets can promote eating disorders.

"Diet is the number one risk factor for developing an eating disorder," says Marci Evans, MS, RDN, a Certified Nutritionist and Eating Disorders Supervisor.

In a study of women, people who followed a rigid diet (as opposed to one who was considered flexible) reported symptoms of eating disorder and were worried about their height. The rigid dieticians typically also had a higher BMI. I saw that in men, too.

There are some important signs that your food is problematic or disturbed. "If your nutritional program ignores the natural signs of hunger and fullness of your body, causes more obsession with food and you feel guilty or shameless, then maybe it's time to consider that your habits do more harm than good," explains Evans.

That is, "Not everyone who adheres to this type of diet will suffer from anxiety or guilt in choosing foods. However, when creating time rules, a condition of "good or bad" arises. "True or False," which makes our relationship to food more emotional, "adds Kara Mohr, Ph.D. (She's my wife, but also co-owner of our nutrition consultancy Mohr Results.)

Conclusion: I'm not saying you never It may even work for you, but if it does not work for you mentally – even if it works for you physically – you may want to re-evaluate it.
