I hear you. I hit 315 some years ago and now weigh 196 and dropping. I'll disappear in 2147, give or take a funeral or 2.
I keep a paper detailing BP, HR and weight on my physical desk right in front of my keyboard and check about five times weekly. This is a daily challenge for me as nothing is more important to me.
I ride an hour a day on a great $200 stationary bike from Amazon. I don't need to blame the gym. (Hint?) And I frame my diet around high levels of fiber including about 4 oz. of chia seeds.
If you matter to you, do something about it. Otherwise you're just another bs-er. Do you want that?
