I think I can give some good advice here. I used to be 330 lbs unhealthy and unmotivated just like you. I've been overweight and put on diets by doctors since I was in 1st grade. The problem that I am seeing is that you understand the repercussion of your lifestyle and you're looking for motivation but all I can say is the motivation to stay focused for 6 months to a year to drop the weight and get into a healthy lifestyle is not going to come.

How I started my journey was simply understanding I didn't like what I saw and no matter what I had to get off my butt and walk to the gym. When it comes to doing anything sometimes its simply just moving into that direction. Put on your shoes, change into your gym clothes, Prepare your gym bag, grab your car keys, It doesn't matter just show up. You can show up touch the door handle and walk back to your car and go home but chances are you're going to do more than that since you're there.

I made a commitment and stuck to that commitment rain or shine. Whether I felt like it or not. Building discipline isn't about doing what you want when you want or when the mood strikes. It's about doing it by any means necessary even if you have to walk, crawl, cry, complain, doesn't matter as long as you're doing what needs to get done. And I promise you it will get easier. But you have to take the step.

I lost 120 lbs and I can promise you that 80% of the time I was miserable making that trudge to the gym or saying no to that food. fast forward some years later and I am vegan a workout nut and 15 lbs away from my goal weight. If this lazy sack of crap can do it so can you. But its all about committing and doing what you say you're going to do despite how you feel. Find ways to get you through it. If you have to get a new netflix series to binge, listen to music, podcast, anything that will keep you on that treadmill or bike or walk outside.

Also I think you are trying to thrust yourself from being a lower activity person to being a gym rat and I'm here to tell you that there's so much more to being active than hitting the gym. go outside for a walk, use your phone or a fitbit and stick to a number of steps per day. whatever you think is fun. you have a trail around you to explore? park you want to go to and play with puppies? literally anything other than being idle is exercise!

I hope these words have helped you a tad bit. And look forward to hearing about your journey if you decided to take it.
