How can I start off my informative essay of getting and staying healthy​

Make it personal...

Explanation:

Sometimes it can feel like maintaining a healthy lifestyle is an overwhelming challenge that doesn’t fit within the realities of daily life. It’s tough to hold down a full-time job, eat well, train for a marathon, make homemade green juice, spend quality time with your family/partner, and meditate for an hour each day.

Of course, healthy living can incorporate all of these things (if you want it to), but it doesn’t have to be defined by grandiose displays of health and fitness.

So much of healthy living is really made up of small things we do daily—things that are so small they don’t feel momentous, but that, done consistently over time, add up to produce big results.
