Weight / Fat loss

Calorie restriction is much more effective for weight loss than exercise.

There are some downsides to exercise:

• Many people overestimate how much it can burn
  
• People often try too much too early and then give up, rather than building up slowly and building fitness. They may also injure themselves in the process.
  
• Vigorous exercise can stimulate food cravings and make people overeat.
  
  

That said, good fitness contributes to weight loss by improving your mood and energy levels. It's also a big help in maintaining a healthy weight after the initial weight loss.
