3.After jogging for an hour, you weigh 2 pounds less. This is  (A) mostly water loss (B) Total fat loss (C) one pound fat loss and one pound  water loss      (D) The thermic effect of physical activity

Answer 1

1. Answer: (D) oranges, carrots, cantaloupe

Food rich in fibre, help to lower the cholesterol levels and eliminates it from the body to a large extent. As a result,it also lowers the risk of artery blocking, myocardial infarction etc.Other options, have a very low fibre content , and higher levels of unhealthy fats.

2. Answer: (D)all of these

The body performs a lot of redox reactions that result in molecules to lose electrons, and form free radicals. Thes entities are very reactive and harm the DNA, lipid and protein structures in our body, body neutralises these with antioxidants. However, if this balance between oxidant and anti-oxidant is lost, it results in oxidative stress.This condition can lead to, cancer, atherosclerosis (hardening), premature aging,neurological and respiratory disorder,chronic inflammatory diseases like rheumatoid arthritis etc.

3. Answer: (A) mostly water loss

One hour of jogging is not sternous enought to cause instant burning of fat. Initially, in one to two hours of working out body loses about 1 litre of water(around 2) in the form of sweat . Hence, the weight loss is mostly water loss.

Thermic effect of physical activity is the amount of energy burned during all physical activities  (as little as standing or talking to working out) performed in a day, so it cannot be the answer.
