Fat Oxidation not enough to lose weight
Fat oxidation not enough for fat loss say Sydney scientists
Australian scientists have rebuffed the claims of recent years that fat oxidation (burning fats as opposed to carbohydrates) is sufficient for promoting fat loss. The scientists from Sydney’s Garvan Institute of Medical Research reconfirmed the obvious (but often unpopular with the general population) notion that the only reliable way to lose weight is to eat less and exercise more.
Using genetically-altered mice, it was shown that although fats can be burned in preference to carbohydrates, it was the unburned carbohydrates that were actually stored as fat. This resulted in the altered mice having the same weight and body composition as the normal mice.
The research was focused on the enzyme which controls whether cells burn fats or carbohydrates, known as acetyl-CoA carboxylase (ACC2). Scientists demonstrated that by blocking off the ACC2 enzyme, cells were now required to burn the fats first, rather than carbohydrates.
The researchers said that previous studies had misinterpreted the process as being able to make fat stores ‘evaporate,’ without people changing food intake or energy expenditure; ‘Our data urges a correction in people’s concept of a magic bullet… something that will miraculously make them thin while they sit on the couch watching television’ said study Associate Professor Greg Cooney; ‘while none of the large pharmaceuticals companies have marketed ACC2 inhibitors, there are many kinds of so called ‘fat-burning pills’ available in the health food, body building and alternative medicine markets, where limited clinical effectiveness data are required’.

So what does this mean for you? Basically that you must exercise and eat a healthy diet based on real foods. Cut down on starchy carbohydrates (Unburned carbs are stored as fat) as they are so easy to overeat and displace healthier foods in your diet.
It also dispels the notion that you must stay in the ‘fat burning’ zone in order to get fat off your body. Train with intensity to burn the most calories, to increase fitness levels and get the leanest you can be.
Every day, more and more studies are proving the obvious. That in order to be fit, lean and healthy, you actually have to live a healthy lifestyle and exercise. There are no magic pills, operations, powders or gadgets that can do this for you.
It’s your decision:
Be overweight, tired, unfit and unhealthy or choose to be fit, lean, energetic and bouncing with good health while extending your lifespan.
It really is up to you. Which will you be?
