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.
