‘I wanted to help my clients but calorie-controlled diets weren’t working for them,’ says Weaver. ‘That led me to go back to my biochemistry textbooks with the question in mind: what leads the human body to get the message to either burn fat or store fat’.
Weaver says that while eating too much and exercising too little contributes to weight gain, other factors play a major part too.
Here are her top five factors all too often overlooked by dieters
The link between stress and obesity is being increasingly confirmed in scientific research and for Weaver, it’s one of the prime reasons people can’t lose weight. That marathon runner was putting her body under so much stress that she gained 12 pounds, Weaver remembers. What was going on?
“When we’re under stress we’re constantly churning out the stress hormone adrenalin and that prepares our body to fight or flee from an attack,” says Weaver.
“Blood supply is diverted away from processes such as digestion to the muscles and causes the body to use glucose, not body fat as its fuel.”
When stress is prolonged, the body starts to make another stress hormone called cortisol which breaks muscles down and having less muscle subsequently slows down metabolism.
