What other people see when they look at you is determined almost entirely by your diet. Nobody can see your muscles if they&#x27;re buried under blubber.<p>How you feel, on the other hand, is hugely impacted by your physical activities. Not only does exercise give you energy and focus, it has a huge impact on mood. Exercise is more effective at fighting depression than most medications.<p>There&#x27;s more to being healthy than being a healthy weight. It&#x27;s probably better to be active and a little bit overweight than it is to be skinny and inactive.<p>Note: I said a litle bit overweight, <i>not</i> obese. Health risks add up quickly if you&#x27;re obese. Being cut and defined like a fitness magazine model is not realistic for most people and confers few benefits beyond aesthetics. Getting out of the obese range is realistic for most people and does confer statistically significant health benefits.
