Keith has struggled with his weight throughout life. Though he would very much like to be thinner and healthier, he claims to have little time for exercise and says he has “no taste for vegetables.” With those limitations in mind, Keith has started researching extreme diets he thinks might fit his lifestyle and help him lose weight. He stumbled upon some information about a “carnivorous” diet, where he would eat only meats and avoid grains and vegetables. Keith likes this idea, since he very much likes to eat meat products. According to the information he read, the idea would be to entirely eliminate carbohydrates from his body and force his cells to use fats for energy. Without carbohydrates around, his cells would store away less fat and would instead burn that fat. Controversies about the impact of such a diet on a person’s cardiovascular health have not deterred Keith from considering this diet. Keith is a little concerned, though, since he also read somewhere that our brains cannot use fats for energy. He certainly doesn’t want to hurt his brain cells by depriving them of energy!

As his healthcare provider, what will you tell him?

Weight loss with extreme diets

Explanation:

Depending completely on fat resources and depriving carbohydrate sources will lead to a metabolic condition called ketosis. Excessive ketosis results in the production of ketone bodies and acidic blood due to excessive fat metabolism.

Fatty acids cannot cross the blood brain barrier system and cannot reach the brain cells. Although the ketones can break the barrier and reach the nerve cells to provide energy in the brain cells, this is still considered not a healthy option.

Extreme diets will deprive essential nutrients like carbohydrates, proteins, vitamins, minerals which are highly necessary for normal growth and maintenance of the human body.

So, a well-balanced diet including all the essential nutrients with regular exercise and a good lifestyle is the key to lose weight for Keith.
