Loss of weight, size and potential atrophy

[DillFit]

Hi fellas, so basically I’ve been lean bulking up a bit and have went from 59kg to 70kg in a few months. Coming to the present, I have started to feel like I’m looking smaller with the scale remaining either the same or creeping lower although I’m eating in a ‘surplus’.
Some info about me:
-I eat the same thing everyday with tweaks to volume of the amount of food.
-I find my caloric need via the calories from my Apple Watch and add 550extra - usually setting me with 3000-3300 per day.
-I train 6days a week (a plan on Tnation)
-As for P/C/F I follow a 35/45/20 meaning I’m having well over 200g protein a day.
The thing I don’t understand is, I gained those 11kg following this with in fact a lower calorie intake so why would my weight start to decline/stunt now? Any help is appreciated!

11kg in a 'few months' is a tad fast. It wouldn't hurt you to stay at the same weight for a while as long as you keep making progress with your routine. If you can't keep making progress, it's a programming issue, not a nutrition issue.

Training 6 days a week is a red flag, that is not necessary for most people and may be counterproductive. What are your current max lifts in the major compounds?

Don't rely on apple watch. Just eat a fixed calorie intake each day. Don't use macro ratios, just a calorie target and a minimum protein intake target.

Cheers mate, I phrased the weight gain a bit wrong with my lowest weight being early July last year but yeah I guess it was fast however my bodyfat is still pretty low (around 11-13%). My lifts have seen a small improvement every few weeks but my deadlift 1RM is 125kg, squat- 50kg and bench -60kg. I'm unsure if my age has any significance but I'm 15 years old, as I forgot to mention previously. I understand my squat is rather low, it was one of those exercises I regrettably avoided and hated...

I would focus on bringing those up, if you haven't used a novice routine with planned progression like Fierce 5 or Starting Strength then do that.

I'll look into them now, really appreciate the help!

Don't worry about the details too much

Don't worry about the details too much

These days I feel like it's necessary, teens usually get 'ripped' by older folk for being uneducated in the sector. True for a vast majority, not for all haha.

The only way something atrophy's is by you not using it or by massive cell death. So basically if something isn't wrong internally to where your muscles stop working, you pretty much would have to be in a coma to atrophy. I suppose you could literally never get off the couch/out of bed/ whatever. I digress though. So the good news is you don't have to worry there haha. Other than that, listen to Mister Suffolk up there and you'll be good.

Been really motivated over the last two days, being more knowledgeable each day. Turns out I messed up and didn't include the bar weight in my records.
