Providing Nutritional Advice and Applying The Principles Of Nutrition Flashcards
What are the goals of any weight management programme?
To prevent the accumulation of excess fat. For those already overweight, to reduce body fat to acceptable safe level to prevent health risks associated with obesity.
Where is whey protein found and why is it useful to the body?
Whey protein is found in milk and is useful in the repair and growth of muscle tissues.
Why does the whey protein supplements offer less nutritional vales than whey protein found in its natural state?
Often dried at high temperatures above 60 degrees Celsius become denatured, which destroys their ability to function.
What is the energy balance equation?
Calories IN (energy) = calories OUT (energy)
What is a positive energy balance?
Calories consumed are greater than those expended.
How can we create a negative energy balance?
By consuming fewer calories than the amount of calories expended.
Why is a slow, sustainable weight loss preferable to dramatic reductions in weight?
To lose body fat without lowering metabolic rate.
What is a sustainable rate of weight loss?
1 pound per week (ideally from body fat).
What is the TDEE?
TDEE is the amount of calories the body needs on a daily basis to fuel all its functions and any exercise undertaken.
What is the most variable component of energy expenditure?
The amount of lean body mass.
What is the function of insulin? Why would higher levels of insulin negatively affect weight loss?
Insulin is a hormone which drive glucose in the blood into body cells. Higher levels of blood glucose and insulin favour fat storage and suppress the burning of fat as fuel.
Explain biochemical individuality.
A diet that suits one person may not suit another. We all exhibit different physical, hormonal, chemical and cellular characteristics that require different nutrient support.
Components of energy expenditure
- Basal metabolic rate (BMR)
- Thermic effect of food (TEF)
- Thermic effect of activity (TEA)
Feed to fire
Regular nutritional intake helps maintain a higher metabolic rate.
Which drink would be used by endurance athletes to top up muscle glycogen stores?
Hypertonic sports drinks
Which of the following methods would be least effective for measuring fat loss?
Skin fold callipers
Weighing scales
Tape measure
Bio-electrical impedance
Weighing scales
3610
Why does the body need a regular supply of vitamins and minerals?
To reduce free-radical damage
During high intensity activity, what fuel contributes the most to energy production?
Glycogen
When glycogen stores are depleted, where does the liver obtain amino acids from for conversion to glucose?
The breakdown of muscle
Name a sign of Bulimia?
Episodes of binge eating.
Increased tooth decay.
Self-induced vomiting.
Smelling like vomit.
Misuse of laxatives and diuretics.
Complaining about body image.
Expressing guilt or shame about eating.

1 dessert bowl of salad
1 medium sized potato
1 glass of orange juice

What is the primary cause of ketosis?
Lack of carbohydrate
With reference to metabolism, what do the initials TEF stand for?
Thermic Effect of Food
What is the name of the disease characterised by a build up (or narrowing) due to fatty deposits within the arteries?
Atherosclerosis
