So this is your chance! Youâre in recovery now and you have the opportunity to build the life youâve always wanted! 1  To get started, look in your heart and soul and find that thing that makes life worth living â and then build a long-term goal around it.  Once youâve got this, the rest is simply mechanics and sweat.
This will provide both fast-acting and sustainable energy to your body. Try to eat a snack within two hours of exercising, but wait a minimum of 15 minutes after exercising before you eat. Bring a snack along to the gym with you, so you can eat as soon as your workout is over.
How long you need to wait before exercising after eating also depends on the intensity of your workout. You should give yourself longer to digest if you're going to be working out intensely (running, aerobics, etc.) than if your workout will be more gentle (walking).
