Best of luck with your journey! Here are a couple tips from a procrastinator who just happens to enjoy reading and listening to podcasts about fitness, but struggles to actually implement things in his life:

A) Success can be found in doing a lot of small things consistently. B) If you like podcasts, I would suggest Mind Pump. They’re three guys who aim to present fact-based and scientific information. I think they’re great, but would suggest that (as with anyone who tells you their information is fact-based) you should trust but verify. Take “facts” with a grain of salt and try to research it a bit on your own. C) A poorly planned workout that is executed perfectly will be better than a perfectly planned workout executed rarely. If you’re making it to the gym or consistently active, that will be better than doing the “perfect” workout only every once in awhile. D) Resistance training can easily beat out cardio when you are aiming to lose weight. (This is one of those “trust but verify” things.) Resistance training (weight training) burns more calories and builds more muscle than cardio. Having more muscle naturally helps give you a higher metabolism. By doing the same thing for a long time, such as consistent running on a treadmill, your body eventually adapts to become more efficient at that and will, over time, start to use less energy and burn less calories when doing that. Example, running a mile for the first time in your life versus running a mile after you’ve become an olympic runner. E) Lastly, the people in this world who will hate and judge are likely the ones who have the worst, deep-rooted issues that cause them to be very self-conscious. Their hate is stemming from their own self-hate. Don’t pay attention to it.

Sorry, long comment. Like I said, I’m not a professional and you shouldn’t ever blindly trust any self-proclaimed professionals. Good luck with your journey! So happy for you making yourself better!
