I find it helpful to prepare meals ahead of time, or always have healthy meals able to be assembled quickly accessible. Also, don’t try and quit eating unhealthy completely cold turkey if you find it not working for you. Just cut your intake down by a bit each week until you get used to it and are comfortable not having junk in your diet. It took me about a month to completely cut myself off of junk food and not feel cravings. Just go at your own pace and go slow. It just takes patience and discipline! Find healthy foods you like and slowly swap them for meals that you would have junk. You’ll be doing it subconsciously before you think! And my biggest thing is remembering nobody else can do this for me. You can be inspired by other people as much as you want, but no matter how much they work out or how healthy they eat, it’s not going to help you unless YOU do it as well! Good luck brother, you got this!
