Congrats on starting this journey. There are a few things you mention here that I want to address so that you actually stick with it.

The first thing is there’s no such thing as falling off the wagon, but prioritize going to the gym above all things in your lifestyle change at least for a month. If you don’t feel like going, just drive to the gym and walk in through the door. If you still don’t feel like doing anything you can just walk back to your car and go back home, but I guarantee you wont do that, you’re already there. On that same token, feel free to half ass it if you don’t feel like going but you do go. The idea here is to create the habit of going to the gym regardless of your will to do so, in a word “discipline”.

The second thing, I would recommend reading a book like Starting Strength or other beginner programs and watching a few videos of someone demonstrating the movements if you don’t have a trainer. A lot of times the biggest hurdle for people who start working out is that they do not know what to do and whether they are doing it right and it kills their motivation to go. If you know what to do and how you’ll be more primed for success.

Now the third thing is a bit of a red flag. I do not know how overweight you are, but 80lbs in 60 days is very difficult, and I might say even unhealthy and maybe even impossible even for someone with extreme obesity, I’m talking someone with a bmi of 50 or more. The other thing is that I think you might be making too many changes too fast, like going from counting calories to keto in 3 days. If it’s working out for you great, keep going. But I would stress that if you fail at staying under your calories or eating keto or losing even half of that weight that you have as a goal, that you do not get into the mindset that that means that the entire lifestyle change has failed and just stop doing everything. If you fail try again. One thing to note about keto, it’s really good for losing weight but not because it burns more calories or anything: calories are calories no matter what. What it does is that it helps you feel satiated for longer and thus helps you eat less. But you can achieve the same weight loss using other techniques like eating a whole food diet and counting calories, or using time restricted eating (“fasting”) or any combinations of these and I would encourage to try and experiment with all of them to see which one is actually easier for you to stick to. I for example prefer fasting when I’m cutting weight along with a calorie reduction without actually excluding any foods from my diet. But this is is me, and you are you and what makes you tick might be different.

At the end of the day getting fit is a lifestyle change and it works best when you do it a little bit at a time rather than making a drastic change all at once. But you ere going in the right direction which is great. Keep at it, you got this, and remember that as long as you keep trying you have not failed.
