With the nation getting ever fatter and the burden this will have on our health and economy, the government and health care professionals alike are urging us to weight loss and become more active. But there are so many different diet books and weight loss programmes on the market and so much conflicting information in the press that it can sometimes be quite confusing about what to do.
From an evolutionary perspective humans are designed to be lean, muscular and highly active. Just look at animals in their natural environment where there is no human interaction – you very rarely see overweight animals except those that store fat before hibernation and you never see obese animals.
Alarmingly the House of Commons Health Committee Report on Obesity estimated the economic cost to the nation of people being overweight and obese to be 6.6 – 7.4 billion. At a time where our economic future looks bleak we need to realise that it is no longer acceptable to let ourselves become overweight or obese. Nor is it acceptable to put the responsibility of our health care on to others such as the government and the National Health Service NHS. We need to take responsibility for the decisions we make in our lives including the decisions that affect our health. Of course there are genetic and environmental factors that contribute to our body shape and our health – but no one gets obese just from having “bad” genes. People only get overweight or obese from what they chose to eat on a daily basis and from lack of exercise.
Fat is not just an unsightly inert substance that sits on your love handles or muffin top. It does not just serve as a reservoir of energy to be called upon when needed for energy. Fat is metabolic tissue that can cause all manner of things to happen in your body. Fat cells release the hormone leptin that serves as a signal for energy sufficiency. Leptin levels decline with calorie restriction and aminofitin รีวิว and rise above normal levels with weight gain and obesity. Obesity can lead to leptin resistance, much like insulin resistance whereby leptin can no longer tell the brain that we are full. This may lead to overeating. Leptin also interacts with other hormones such as stress and thyroid hormones, it modulates the immune system and aids bone formation. Disrupted leptin levels through obesity can affect how these hormones work, affect the immune system and alter bone formation.
Fat cells become infiltrated with high levels of immune cells that release inflammatory chemicals disrupting the uptake of sugar and burning of fat in liver cells contributing to insulin resistance, the onset of type 2 diabetes and narrowing arteries. Fat cells release chemicals that clot your blood, increase your blood pressure and convert inactive stress hormones into active stress hormones and contribute to conditions such as hypertension, stroke, cardiovascular disease and PCOS.
