Four Common Myths About Exercise And Weight Loss

0 Flares 0 Flares ×

Its that time of year when many are trying, and some are failing, to live up to their New Years’ resolution of lose weight. Many of these likely include resolutions to be more physically active in striving for this goal. But first, there are some common fallacies about exercise and weight loss that need to be addressed.

Myth 1. Exercise/ is The Best Way To Lose Weight

While there is plenty of evidence presenting people can lose weight only by being physically active, it is also one of the hardest routes to go about it.

Our energy balance is largely determined by what we feed and our metabolic rate( the energy you burn when you do nothing ). Our energy balance is determined only to a small extent by how active we are. That entails losing weight merely by being active is very hard work.

The American College of Sports Medicine recommends accumulating 250 to 300 minutes of moderate intensity workout per week for weight loss. That is twice the amount of physical activity recommended for good health( 30 minutes on most days ), and most Australians dont even manage that.

The best style to lose weight is through combining a nutritious, low-calorie diet with regular physical activity.

Myth 2. You Cant Be Fat And Fit

Inactive people of healthy weight may look OK, but this isnt inevitably the case. When youre not active you have a higher risk of heart disease, diabetes, high blood pressure, osteoporosis, some cancers, depression and anxiety. Several analyzes have demonstrated the association between premature death and being overweight or obese disappears when fitness is taken into account( although another study disputed this ).

This means you can still be metabolically healthy while being overweight, but only if youre regularly active. Of course, people who are fit and of normal weight have the best health outcomes, so there are still plenty of reasons to try to shed some weight.

Myth 3. No Pain, No Gain

Or in other words , no suffering , no weight loss. As mentioned earlier, if you want to lose weight by being active, you will need to do a lot of it. But while physical activity of a moderate intensity is recommended, guidelines do not say activity needs to be of vigorous intensity.

Moderate intensity physical activity constructs you breathe harder and may make it more difficult to talk, but you should still be able to carry on a conversation( such as brisk walk-to, riding a bicycle at a moderate pace ). This is unlike vigorous physical activity, which will stimulate you totally out of breath and will build you sweat profusely regardless of the weather conditions( such as operating ).

Moderate intensity physical activity is not painful and does not include excessive agony to meet your goals. A study of weight loss in groups with higher intensity and lower volumes of activity compared to groups of lower intensity and higher volumes of activity did not find significant differences.

Myth 4. Merely Resistance Training Will Help You Lose Weight

Resistance or strength train is good for you for several reasons. It increases functional capacity( the ability to perform tasks safely and independently) and lean body mass, and prevents falls and osteoporosis. But the main idea for promoting it to lose weight is that muscle mass needs more energy than fat mass, even when at rest. Therefore the more muscular you are, the higher your metabolic rate, which constructs it easier to expend the energy youre taking on board.

However, constructing muscle mass takes a serious effort, and you need to keep doing resistance training or significant loss of muscle mass will occur within weeks.

More importantly though, aerobic or endurance develop is also good to help you lose weight. In fact, a recent survey demonstrated that endurance develop was more effective in producing weight loss compared to resistance develop. Its also likely many people will get more enjoyment out of a brisk stroll than a session of weight-lifting, so the most important thing is to pick training exercises routine you enjoy and thus will actually stick to.
