PLC EXAMS & ELECTIVES 

THE ROLE OF THE REGISTERED DIETITIAN

 

  1. FOOD DIARY:  

The Patient is to fill out a 3-day food diary before their appointment date. Upon receiving it,  the RD will enter in all the food and drink and amounts noted in the database. This will calculate the amount of protein, carbohydrates, fat, saturated fat, unsaturated fat, calories, fiber, and any vitamin & minerals the pt is deficient in. This will be gone  

over when the pt meets with the RD at their appointment date. 

  1. CAS (Coronary Artery Screening or Calcium Score): 

Measures how much-calcified plaque a patient has in the major coronary arteries. It detects the presence and extent of early atherosclerosis. The RD will go over the test with the patient. If the patient has a positive score, the RD will go over foods that should be avoided in the future to help stop or slow plaque formation. 

  1. Visceral Fat Score: 

This shows how much visceral fat a patient has. Visceral fat is the fat that surrounds the major organs. The average score is 140 cm2. If a patient has a score noticeably higher than the average score, the RD will recommend weight loss (fat loss) to help lower the score. A very high score indicates that a person has a high incidence of heart disease or diabetes in the future. 

  1. DEXA scan (Dual Energy X-Ray Absorptiometry)

This test will show if a person is at risk for bone loss, osteopenia, or osteoporosis. After age 30, our bones break down if we are not doing anything to help them stay strong, which includes resistance training (higher weights with fewer repetitions) and consuming adequate amounts of calcium and vitamin D3. The dietitian will go over foods high in calcium and vitamin D3 for the patient to increase in their diet. Minerals and vitamins that also keep the bones strong are magnesium, boron, and vitamin K2. If the patient cannot get enough of these through their food daily, a supplement is warranted. If the patient follows the RD’s recommendations, this is reversible; which means the bones will get stronger. 

  1. Body fat: 

This is measured in the DEXA scan test. Body fat is NOT the same as BMI (Body  Mass Index); which most patients get confused with. Body fat is the number of fatty muscles in the body which represents the total fatty tissue that does not contain muscle mass. Body fat percentage is calculated by taking the total mass of fat dividing it by the total body mass and multiplying it by 100. A person’s body fat differs between men and women and also by age.

  1. RMR Test (Resting Metabolic Rate): 

This is an elective test that measures how many calories the patient burns at rest and how long it will take the patient to achieve his or her goal weight by exercising and not exercising. It also shows if the patient has a slow or fast metabolism. How it works is the patient breaths through a tube for 10 minutes. When the test is completed, the RD will add the information to the database, which includes the patient’s weight, the patient’s goal weight, the patient’s sex, and the patient’s age.  

  1. Weight Loss and Nutrition Coaching: 

This is one of our new electives. This can either be done with or without weight loss drugs. With either one, the patient will have access to the “Lose It” app. The patient will enter their food daily. The RD will go over it and make recommendations to the patient at the 4-week mark via a Zoom meeting with the patient. If the patient ops for the weight loss drug, the doctor will write a script for the patient for the lowest dose, after one month, the patient, dietitian, and doctor will decide if the patient will go up in dose or stay the same.  

  1. Women’s Health: 

This is also one of our new electives. The patient will meet with one of our gynecologists on staff, which includes an assessment and going over any recent tests. The RD will educate the patient on what to eat vs not eat to help reduce or prevent any peri-menopause or menopausal symptoms.
