How could MFP/other TDEE calculators be so off? Need help on my math here please— 24M

Genuinely need help on this y'all. 24, 5'5 M. Hovering around the 155-160 range rn. Run about 30 miles/week and lift 4-5 times per week.

Around 4 months ago, I set out to lose about 20-30ish lbs. The weight fell off rather quickly. My whole philosophy when I began was to do it slowly, steadily, and healthily, as many previous weight loss initiatives — particularly when I was younger — were far too aggressive to be maintained.

So, I started at about a month of a ~250 cal/day deficit. I escalated eventually to a ~500 cal/day deficit. I didn't even log my weights for the first two weeks of my weight loss, so the initial water weight drop isn't a factor when I say I consistently was losing about *2 lbs per week,* despite having aimed for a much less aggressive rate.

I dropped from 180 to 160 rather quickly at a rate of 2.1 lbs lost per week. I averaged about 10 lbs down per month. On MFP, I set my activity level to "Active," and my desired rate of weight loss to 1 lb/week. I was eating somewhere in the window of 2700 calories per day, +/- 250 calories, *losing 2 lbs per week.* According to MFP, I should have been losing 1 lb per week; additionally, according to ChatGPT/Gemini's calculators, 2700ish should have realistically been my *maintenance*, even factoring in my physical activity.

So how on Earth were they that wrong? Based on my calorie intake and actual rate of weight loss, my actual TDEE was probably often somewhere around 3700-4000 calories. Which *shouldn't make sense.* Yes, I run a lot and lift a lot, but I always made sure to enter the extra active calories burned from my workouts. I logged everything to a T, used my scale and measuring cups religiously. I logged my food and exercise as accurately as possible.

My diet ended up crashing and burning when I began to see results and got carried away. Foolishly, around the 160 lb mark, I upped the goal in MFP to 2 lbs/week and, on the advice of ChatGPT, reduced my activity level to "Lightly Active." (I was still adding extra calories burned from my actual workouts.) Technically, this *should* have worked based on my stats and activity level (student/desk job), but I ignored the real-world data, ie the scale.

As you'd expect, upping beyond what is generally regarded as the safest maximum rate of weight loss (2 lbs/week) yielded some pretty poor results. My energy levels tanked. Irritability was high. Social drive was low. Libido practically gone. Then, went on a family vacation, had one night where I let myself splurge, which subsequently has led to several nights of binging when I got back home.

I got to about 147 lbs before my body tapped out. I've already gained a bit of the weight back. Not panicking about it and letting my body rest. It should go without saying that I am taking a diet break to both give my body & mind time to find equilibrium.

But for when I'm ready to hop on the wagon again: what on Earth do I do when my body is defying all the formulas, even going beyond generous TDEE estimates? Do I just chalk it up to being young, active, and 24? I genuinely want to do this whole thing *right* and sustainably, and plan to go back in a hell of a lot more gently and wisely when my body is ready. I tried to do it right according to the book, but ignored the real-world feedback.

Any advice?

Thanks in advance y'all.

Motivation tips please, I’ll be so appreciative

I’m one of those life after Christmas strugglers, guys. I had the time of my life living it up and gained 5 lbs in two weeks. HOWEVER, summer is coming and I need to get real. Here’s the lowdown: I’ve lost 16 lbs in 2025. My goal is a further 16 lbs and my motivation is really, really hindering me. I think I’m definitely a sugar addict of some sort, or have a coping mechanism of eating sweet things as a “treat”. I’ve been successful to a certain point with food noise but I’m still in the midst of going “how the hell am I going to do this?!” I live in a calorie deficit and exercise 4 times a week, and do 10,000 steps a day. I’m just a bit stuck. If anything I would love to hear others and their experiences about how to get BACK into motivation, weight loss. I’ll be ever grateful. Someone suggested doing a AI pic of myself thinner, or getting an item of clothing size smalller…I want it, but struggling to get back on the horse. I will do it! But thought I would ask Reddit for help…

Should I increase my calories from 1100 to 1500?

Hey everyone, I’m a 23 M, 5’6”, and I started my weight loss journey exactly one week ago. My starting weight was 173 lbs, and currently down to 165 lbs. I know a good chunk of that 8lb drop is likely water weight, but I’ve been hit pretty hard by the hunger wall. For the past 7 days, I’ve been eating a strict 1100 calories a day, and by the time I get to the end of the evening, I am still a bit hungry. I’m starting to realize that 1100 calories probably isn't sustainable or healthy in the long run. My goal is to get down to 155 lbs, and I’m thinking about bumping my intake up to 1500 calories a day. I’m looking for some input on whether 1500 is a more realistic "sweet spot" for my stats and if anyone else has successfully transitioned to a higher calorie count without stalling their progress completely.

Content creators - who do you follow for ideas?

Title says it all, who do you follow for meal ideas and whatnot?

I mostly use FB and YT, and follow The Plant Slant and Slow Slimmer, but I'm always open to new ideas of people who post meal ideas, etc...

I also follow PlantYou, not specifically for low calorie ideas, but for delicious meals that taste amazing, and I just tweak em a bit sometimes.

Are there any non-American weight loss content creators that post meal ideas, etc? It can get very hard to find some USA ingredients or they cost a LOT if you're not in USA.

Am I going too hard?

I’m trying to lose weight, but a couple people in my life have said that I’m going too hard. I’m 5’3 (162cm ish) female, and 108kg at the moment. On New Year’s Eve and New Year’s Day I weighed in at 113kg so I’ve lost 5 kg since starting on the second. I have my Lifesum app set to a goal of 7911 kj per day, but I’m regularly about 1000-2000kj under this.

On top of that I’ve gone from an almost completely sedentary lifestyle last year (except for a few blips where I’ve tried to be more active) to getting half an hour exercise atleast every day, plus 1 hour exercise 3 times a week. I have my “move goals” on Apple Watch set to 2500kj on my rest days and 3500kj on the 3 days a week I go to the gym. I spend an hour at the gym, sometimes more, and do 20+ minutes of cardio and then the rest of weight training. I haven’t missed any days this month, with the exception of course of new years as I was nursing a hangover so properly started on the 2nd.

I did do this for a month last year but I fell out of it because I had been doing it with a friend, and when that friend lost motivation I also lost motivation. Conveniently, it’s also this friend who is saying I’m going too hard. But it’s also his brother (who also had a weight loss journey and is now super fit), and my fiancĂ©.

I don’t know what to do

Okay guys, I started my weight loss journey in May of 2024 and since then lost 72 pounds so far (25F, 5’6 and when from 252 to 180). Since recently I can’t lose weight it’s literally stuck on 180 for almost 2 months. I got frustrated and than started binging these last 2 weeks. I can’t stick to my diet (eating 1450kcal a day, if I eat more I don’t lose any weight), I always eat a lil extra and it has gotten me to 180 but recently nothing is helping. I started working out more and nope, I changed my diet and also nope. I feel very sad, I came so far and now I can’t even get to my GW. What can I do???

Dietitian + PCOS

Has anyone had experience with using Nourish or seeing a dietitian on your own/through another platform for help and guidance managing your PCOS through nutrition, supplementation, and lifestyle changes for weight loss? How has having a dietitian helped or not helped you, like did it keep you accountable and consistent with your efforts, or did it make it harder? I want to know everything, as I am currently signed up on Nourish to see a dietitian for PCOS and weight loss in February, and I will be paying out of pocket, so I want to make it worth it. Thanks in advance!
