Depending on your finances, maybe find stuff to eat whilst out alone.

Even something simple like if you're buying a coffee, go to Greggs and get a pizza with it (I think it's around £3.50 vs £2 for the coffee alone).

I would first check to see what's in your area, don't just consider the larger ones like McDonalds but maybe smaller independent places which might offer better value.

For example, some days I might have 3 triple cheeseburgers and large fries from McDonalds, another day a large take out pizza from the Pizza Hut down the road and another time a doner kebab with cheese fries from the independant.

Also check out any food delivery services in your area, I got a bunch of take out food a while ago because of some offers from Amazon/Deliveroo.

I would double check with the airline to make sure it's on file that they're ok with a "person of size" flying (IIRC that was an actual term used).

Generally the only issues I've ever heard is the seat size and other passengers, maybe try and get an bulk head seat if you can for extra leg room.

On a side note, airline food is generally bad from my experience, so maybe bring some snacks and/or make sure to eat before flying.

I've been overweight since I was a kid, so I subconsciously suck in my gut to some degree, though these days it feels like just the lower part of my belly is slightly affected.

If I consciously suck in my gut I can pull it in quite a way though.

That said, I long for the day that my belly is large enough with a good hang over my waistline, enough that sucking has no real difference.

What kind? I ask because there's a difference between say McDonald's and a decent independent take away from my experience.

McDonald's I could easily eat 2, probably more but I don't want to spend too much.

I'm not fond of BK, at least where I live in the UK, although they seemed better when I was on holiday in Spain in both quality and value.

Overall though, I prefer the burgers from the smaller/independent fast food places.

I've been in a similar position, with a 3-4K goal.

When I started I would do on/off periods of excessive eating by making sure I had 3-4 meals a day of around 500-1000kcal with snacks in between and having double cream Ice Cream milkshakes, even if it felt a bit uncomfortable.

Over time though I think this is having an affect on me and making it easier to eat more, although still not perfect.

If costs weren't a factor I'd probably be eating even more, especially things like McDonald's which I find 'empty kcals', handy when eating just before starting a shift.

Reminds me of a post I saw where someone mocked a fat person for trying to lose weight at a gym.

Although I think this was a YouTube Reddit r/facepalm compilation video, so at least they were getting mocked for it.

I developed this fetish a couple of decades ago during my teen years and it never left me.

As of now I feel like I have to try and get fat enough that I have a permanent slab of fat across my waist line, even if I end up regretting it and try to lose it.

I find it kind of ironic that I hated being a fat kid /teen but hate not being fat enough as an adult.

You'll often find discussions on here of people stuffing themselves, personally though I find this uncomfortable.

Instead when I'm pushing myself to gain I use the 'little and often' approach, basically spreading out the amount of food I eat throughout the day. So instead of say one massive meal, I might have two smaller ones a few hours apart.

Remember, at the end of the day it's about the overall kcal intake.

Find food/meals/snacks which aren't filling but still high in kcal, McDonald's is a good example for me.

Also, if you go down the cream route, I make Ice Cream milkshakes and found using a relatively cheap small smoothie blender which has small bottles allot easier than my larger blender.

I'm not the OP, their post has been deleted.
