Question

The patient has changed his eating habits over the past 6 months. He started to control the amount of calories he consumed and kept it below 3000 kcal/day. He got a membership at the local gym, but due to his busy schedule he wasn’t been able to spend time working out “maybe goes once a week”. Four weeks ago he started a “fad diet” to help him lose more weight. He is 26 years old now, his blood pressure is 125/76, he weighs 200lb, he is 5'9" and his waist circumference is 40in. He recorded what he ate during the last 2 weeks and these are the results: 2700 kcal/day (total daily intake), 1000 kcal from lipids, 1200 kcal from protein and 500 kcal from carbohydrates.

Do you think there have been changes in the way he metabolizes lipids since he started the diet? What kind of changes? Explain.

Answer 1

Fad diet also called as cult diet.A very unhealthy diet plan to loss weight quickly.It mainly includes to eat less,move more and eat fruits and vegetables.

It includes variety of food like liquid diet,food combination, dietary supplements,herbal products,high carb low fat diet.

Lipids are usually metabolised in form of fatty acids to get energy.It is broken down to free fatty acids by oxidation this method is called lipogenesis.Here FAD is converted to FADH2 by reduction method.

Here he has started eating more amount of lipids and it has to been metabolised to get energy and excess is stored in liver for future use.

He will loss weight very quickly but he thinks of coming back to the normal diet his appetite will go up and he will start eat more and gain weight.
