身体健康从何处入手?

Exercise, any kind
任何种类的锻炼

You can run, lift weights, do yoga, take classes-there are tons of options. Any exercise is better than none, and if you're feeling out of shape, try doing a little more than whatever you're currently doing.
可以跑步、举重、瑜伽、上健身课--选择很多。锻炼总好过不锻炼，如果你觉得状态不佳，试着在目前锻炼的基础上，略微加大运动量。

A healthy week's worth of exercise should include: Some cardio, some strength training.
健康的一周应包括如下锻炼：有氧运动和力量训练。

You might be a runner who gets in a few strength sessions, or a lifter who hops on the rower for a little cardio once or twice a week. Or maybe you play a sport that gives you a good mix of both in every practice.
可以在跑步的同时上一些力量训练课程；可以在举重的同时划船（有氧运动），每周一至两次即可。或者，你也可以进行其它两者兼容的运动。

If you're new to everything, explore until you find something you love. Then find a program, team, coach, or long-term goal to structure the rest of your training.
如果你是健身新人，慢慢探索吧，总会找到你最爱的运动。然后开始制定计划、找到团队、教练或制定长期目标，为接下来的锻炼做出规划。

Sleep enough
睡眠充足

There are entire industries that sell things to people who don't have enough "energy." You could buy their vitamins, gadgets, or motivational advice...or you could just get enough sleep in the first place.
各行各业都有针对睡眠不足者的产品。可以买维生素、有助睡眠的科技小产品，或采纳激励建议……再或者，获得充足睡眠就可以啦！

If you routinely get six hours or less, fixing that will probably solve a huge number of what might otherwise seem like health or "energy" related problems. Most people need between six and nine hours. The way to get more sleep is usually just to rearrange your morning and evening schedules to allow yourself enough time in the sack.
如果你一般只能睡6小时或低于6个小时，解决这一问题或许会连带解决一系列与健康或"精力"相关的问题。大多数人需要睡6至9小时。如何获得充足睡眠？只要重新规划早晚时间表，留下足够的睡眠时间。

Eat a non-crappy diet
饮食不油腻

There are many healthy ways to eat, so don't worry too much about whether you've found the optimal one. All of the healthy diets involve lots of fruits and vegetables, and not too much sugar.
健康的饮食方式多种多样，所以无需过于担心是否找到了最佳饮食。所有的健康饮食方式都包含大量的水果和蔬菜，且要求少吃糖。

If you're trying to lose weight, know that all of the diets and fasting schemes out there work the same way: they result in you reducing your calorie intake. Beyond that, they each have their own pros and cons: you might feel more full and satisfied on the high-fat content of the keto diet, or you might prefer the simplicity of intermittent fasting, or maybe you enjoy a lot of the foods you can eat on an old-school low-fat diet.
如果你正在减肥，那应该知道所有的饮食方式和禁食计划都起着一样的作用：减少卡路里摄入量。此外，每一种饮食方式和禁食计划都有着各自的优缺点：高脂肪的生酮饮食会让你饱腹感更持久、更满足；间接性禁食更简单；老派的低脂饮食能让你享用更多美食。
