‘Fat burning zone’? The best way to exercise to burn fat

 Article taken from The Conversation Authors:  Justin Roberts Principal Lecturer, Anglia Ruskin University   Ash Willmott Lecturer in Sport and Exercise Science, Anglia Ruskin University   Dan Gordon Principal Lecturer Sport and Exercise Sciences, Anglia Ruskin University When it comes to losing weight, people often want know the best way to shed excess pounds – and there’s no shortage of fad diets or fitness crazes claiming to have the “secret” to fat loss. One theory even suggests that exercising at around 60% of your maximum heart rate will bring our bodies into a so-called “fat burning zone”, optimal for losing weight. But does this “fat burning zone” even exist? First, it’s important to understand a little about our metabolism. Even if we were to sit at our desk all day, our body still needs “fuel” to meet energy demands . This...

Factors affecting enzyme action

Just started on the WOW fat/weight management program. Its all very experimental as it is all about understanding how your body works in response to the food you eat and factors that impact the enzymes optimal reaction (in digesting fats). Factors affecting enzyme action. Physical factors affect enzyme activity. Article from  Bitesize Temperature At low temperatures, the number of successful collisions between the enzyme and substrate is reduced because their molecular movement decreases. The reaction is slow. The human body is maintained at 37°C as this is the temperature at which the enzymes in our body work best. This not true of the enzymes in all organisms. How temperature affects enzyme action Higher temperatures disrupt the shape of the active site, which will reduce its activity, or prevent it from working. The enzyme will have been denatured . Enzymes therefore work best at a particular temperature. Proteins are chains of amino acids joined end to end. This chai...
