r/loseit on Reddit: Weight loss timescale calculator (that was extremely accurate for me)
August 16, 2020 -
I was browsing Reddit when I came across an old post with a link to a calculator - you input your details and the number of calories you're planning to eat daily and it comes up with a timeline for when you should hit certain weights.
https://www.losertown.org/eats/cal.php
I thought I'd share as I found it super accurate. I put in my starting weight and it calculated it would take me 12 weeks to get to the weight I am now (give or take 1lb) and I did indeed begin calorie restriction 12 weeks ago so it's worth a try if you're wondering how long your weight loss journey is likely to take! It also shows how your calorie deficit reduces as you lose weight which I also found really useful.

By 2022 I can be down to just 14 lbs!

I’ve looked at that before, but not since having an updated weight to compare to my starting. That chart is eerily accurate, only 0.6 off. Somehow, knowing that the math is backing me up makes me way more confident in what I’m doing. That’s definitely never a feeling I had in math class!
