ANS THE QUESTION NO:3

A)  It is not true that overweight people have slower metabolism .Fat people have faster metabolisms than thin people. 'What is very clear,' says Dr Jebb, 'is that overweight people actually burn off more energy. They have more cells, bigger hearts, bigger lungs and they all need more energy just to keep going.

B) P𝚛𝚘𝚏. O'R𝚊𝚑𝚒𝚕𝚕𝚢 𝚜𝚊𝚢 𝚝𝚑𝚊𝚝 𝚏𝚊𝚝 𝚙𝚎𝚘𝚙𝚕𝚎 𝚊𝚛𝚎 "𝚗𝚘𝚝 𝚠𝚎𝚊𝚔-𝚠𝚒𝚕𝚕𝚎𝚍, 𝚜𝚕𝚘𝚝𝚑𝚏𝚞𝚕 𝚘𝚛 𝚕𝚊𝚣𝚢' because fat people have a medical condition due to a genetic defect and that causes them to be obese. He think the mainly causes them to be obese is genetic.

c) Prof. Friedman gave the fat mouse leptin and it lost 30% of its body weight in two weeks.Actually Prof. Friedman found that unlike its thin brothers, the fat mouse did not produce a hitherto unknown hormone called leptin. Manufactured by the fat cells, leptin acts as a messenger, sending signals to the hypothalamus to turn off the appetite. Previously, the fat cells were thought to be responsible simply for storing fat. When one cousin was given leptin, she lost a stone in weight .

D) Prof. O'Rahilly   hired a doctor to develop a test for leptin in human blood, which eventually resulted in the discovery that neither of the children's blood contained the hormone. When one cousin was given leptin, she lost a stone in weight and Prof. O'Rahilly made medical history. Here was the first proof that a genetic defect could cause obesity in humans.

E).Professor lan Caterson says while major genetic defects may be rare, many people probably have minor genetic variations that combine to dictate weight and are responsible for things such as how much we eat, the amount of exercise we do and the amount of energy we need. When you add up all these little variations, the result is that some people are genetically predisposed to putting on weight.
