Weight loss and perseverance

I did a bunch of research into how calorie burn rate changes with body weight. The simple rule of thumb is that it reduces by 10% with each 25 lbs lost.

For example, if you need 3500 calories per day to stay even at 300 lbs then you only need 3150 calories per day to stay even at 275 lbs...and only 2800 per day at 250 lbs.

What this also means is that the daily caloric difference being used to achieve weight loss needs to be adjusted accordingly in order to keep losing weight.

This is why I have been using my weight as part of my calculations to regularly adjust the caloric difference as I go.

For me, my starting point was 3800 calories per day to stay even based on my activity level, so I reduced my intake to 3500 calories per day. Now I am at about 3100 calories per day to stay even and my caloric intake goal is down to 2800 calories per day.

But to give it an extra kick that I can sustain down to another 50 lbs lost, I changed my caloric intake to 2500 calories per day 2 weeks ago. I will adjust again as I get to that weight level.
