Chewing the Fat
Cutting down on fat seems such a clear-cut way to lose weight and improve health that it appears to go without saying. However, as with so many universally accepted health claims, this one does not tell the whole story. When you consume large amounts of fatty food, you will definitely put on weight, but the same goes for carbohydrates and – to a lesser extent – other food groups. In fact, some whole fat foods like nuts and seeds are healthy and help you stay full for longer, meaning you end up eating less. Fat is a necessary part of any diet, and while some fats are better than others (e.g. fish oils over greasy French fries), anything consumed to excess is a recipe for disaster.

Stretching the Truth
To avoid pulling, tearing or otherwise injuring muscles, you should always warm up, right? Actually, there is little evidence to show that this is the case. While some of the world’s top athletes swear by a rigorous warm-up, others have cast real doubt on the practice by admitting that they don’t attach much importance to it at all. Several major studies have indicated that static stretches such as touching your toes yield no discernible benefit. In fact, some evidence suggests extending the limbs in this way for too long can actually impair performance on the track or in the gym.

No Pain, No Gain
There is a common belief that the best kinds of workouts are the ones that leave you aching and sore. However, while an element of discomfort is natural during any kind of physical exertion, the idea that effective exercise has to hurt is just wrong. Working out should be challenging, not painful, and serious pain in any part of the body is usually a sign that all is not well in the area concerned. Once you figure out and stick to your body’s limits – maybe pushing a little past them, but not overdoing it – you’ll get a lot more out of your workout.
