    Trying to lose weight can be difficult, and while we all know exercise and diet are both  basic needs, which one is more important?

If you had to choose, should you be hitting the gym, or eating salads? There are many ways you can burn a few hundred calories (卡路里): running for 20 minutes, an hour of swimming, or singing your favourite song 23 times. But the point is, it takes time to burn a lot of calories even with most tiring activity - not to mention the time spent on the way to the gym, and then back home to clean up.

Now, compare this to the number of calories in a chocolate bar - which is often over 200 calories. You could either walk for about an hour to burn that 200 calories, or you could simply not eat that chocolate bar. Which sounds easier to you? How about running for 30 minutes every day or cutting out those two cans of soda? Many physicians point out that there is a lot of high-sugar, high-fat, high-calorie foods we could cut from our diet, to see weight loss results more quickly. And studies also show that diet does actually play a bigger role in weight loss than exercise. A survey of 2000 children found that the level of physical activity was not the main reason for their weight. And a study of 3000 adults discovered that cutting down calories was connected to greater weight loss than exercise alone.

Of course, exercise has many health advantages besides weight loss, like slowing the aging process and improving mental health. But at the end of the day, if you expect to lose weight, you’re likely to get more bang for your buck if you focus on your diet first.
