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.

I use this and though it’s not some kind of bulletproof science, it encourages me so much to see how much I could weigh in x weeks/months if I stick to the plan. I hope it encourages you too! More on reddit.com

What calorie calculator do you trust?
I use https://tdeecalculator.net/ Edit - I ran your info on both these sites and it looks like 1200-1800 is pretty close depending on how active you are. I think your maintenance is around 1800 if you kill it in the gym and 1,300 if you don't do anything. You could try to consume 1,400 and continue working out. See how you feel and track your weight for a few weeks. More on reddit.com
