Weight Loss Calculator by Everyday Health
February 27, 2024 - Most weight loss calculators will use your goal weight to generate a calorie amount that should lead to gradual weight loss. Weight loss calculators often ask your desired goal date for your desired weight to help determine your calorie goal. If you wish to lose weight faster, the calculators give a lower daily calorie goal.

How long are you planning to track your calories?

Til the end of time for me. Past has taught me that I can't be trusted without guardrails. There will probably be days here and there where I eyeball my food intake though.

What Happens When You Reach Your Goal Weight?
Introduce periodization cycles into your life. This keeps it fresh and interesting. Once you reach your target weight, transition to maintenance. Strictly track. Do this for 2-3 months. Then transition to a 2-6 month cycle of intuitive eating. Weekly check-ins with the scale just to know what's going on with your weight. At the end of an intuitive eating cycle, return to strict caloric deficit and tracking for a couple months. Or adjust as needed. Give yourself a month of slight caloric surplus as a treat. Especially around special occasions or holidays. The long term goal is to get as comfortable, confident, and familiar as possible with maintenance intuitive eating. Learn to listen to body signals. Learn when you're body is being honest, or when it's being deceptive with it's signaling. Also get familiar with your body shape. If you notice changes, you can intuitively make adjustments to stop or reverse a change, before you require month(s) of strict tracking and exercising. The better you get at intuitive eating and intuitive fitness, the longer you can be in an stress-free and tracking-free intuition maintenance cycle. Some people can maintain this for years or decades. My ex-gf's mother was this way. She was a lifelong intuitive eater. Never learned how to diet and never properly did the gym. She had a phenomenal appearance just because she knew how to eat naturally & found a great long-term balance with her mind and body. Periodization cycles allow you to incorporate diversity, intensity, and leniency into your yearly routine. It's easy to go hard for a few months. It's difficult to go hard 12 months a year. The cyclical nature provides balance and prevents a weight gain spiral that undoes months to years of intensive dieting and working out. It's also great training and practice for intuitive eating. As each time you return to an intuitive eating cycle, you get another opportunity to do it better and longer than the previous cycle. Get good enough, and you can drop periodization cycles entirely :) More on reddit.com

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.
