   True
   False

1. In Asian populations the relative risk of mortality from obesity significantly increases at BMIs between 23-25.
   True
   False

1. Thin people are always healthier than overweight people.
   True
   False

1. The average Australian consumes about 70-100 grams of hidden fat in processed and fast foods (high in saturated and trans fats) rather than as more desirable oils and margarines added to home cooked meals.
   True
   False

1. Hydrogenated vegetable shortening used by the food industry can contain more saturated and trans fats than beef tallow.
   True
   False

1. There is emerging evidence that high saturated fat tropical milks/cream/oil (eg coconut milk) may not be adverse to health if consumed in traditional Asian/Pacific meals with fish and plant foods.
   True
   False

1. If you are consuming a 2000 kcal diet, the recommended fat intake is 50g which is equivalent to about 2-3 tablespoons of oil/margarine daily, assuming there are no other hidden fats in your diet.
   True

1. Swimming and cycling are better than walking for body fat loss.
   True

   True
   False
   
2. Abdominal circumference is a better indicator of health risks than BMI and waist to hip ratio.
   True
   False
   
3. The Basal metabolic rate accounts for around 70% of total energy expenditure mainly due to total lean mass. Therefore preserving muscle mass with exercise should help maintain a high basal metabolic rate and assist weight loss.
   True
   False
   
4. Pharmacological treatment is commonly used where a person’s BMI is over 30, or lower if risk factors for cardiovascular disease are present.
   True
   False
   
5. Studies have shown that energy restriction without exercise results in both loss of fat and lean mass.
   True
   False
   
6. Studies have shown that fat loss can only be achieved with regular long sessions of walking (e.g. 40 minute sessions) as opposed to several short daily sessions (e.g. 4 lots of 10 minutes).
   True
