Cheat/ More Relaxed day

The question about the age is both yes and no. In my 20s I could eat pretty much whatever I wanted as long as I chased it with a run, and that worked for me right about up to my late 30s.
You are fortunate/lucky that you are thinking about how this all works in your youth; I wish I had done some things differently. I feel like the learning curve is huge and I learned so much from researching this site and a few others.
I personally just don't do cheat days, bc it doesn't work for me, but if I know I am going to be eating out in advance I will bank calories, so that I can eat comfortably without stressing about going too much over my allowances for the day. For me getting to "cheat" a little here and there as long as it fits into my macros works better for me and my lifestyle, but I'm sure others will chime in and offer you some differing opinions and you have to ultimately do what works best for you.

I eat what I want as long as I have the calories for it. I try to do small things to cut the calories too. Today for instance, my boyfriend and son wanted burgers for lunch so I allowed myself one without cheese and wrapped in lettuce rather than having a bun. You have to figure out what works for your body.

I agree... I don't have cheat days because if I really want something I have it... Like chocolate... Have some every day... Less than I used to and the 70% kind now but I log it all and try as much as possible to be as close to my goal as I can... If you know in advance you are going out than getting in more exercise earlier in the day can help.. Try to keep portions smaller or share with a friend . You shouldn't feel guilty about food. It is one of life's pleasures and our body's fuel... Just try to make healthier choices most of the time... I love how every day on mfp we get to start with a clean slate... And yes. I want to say younger bodies are more forgiving than older ones...

I don't tend to think of overindulging or eating certain foods or whatever as "cheating"....IMHO, this term and this mentality at best suggests a lack of ability to view your diet (noun) on the whole and see the bigger picture...at worst, it indicates at least some minor disordered thinking and a crummy relationship with food.

I live a very healthful lifestyle...I am very conscious of what I eat both in terms of quality and quantity and I'm also very active. That said, I eat "treats" and things that many people would think as "bad" on a fairly regular basis, but as a whole, they do not make up the bulk of my diet (noun). I also occasionally overindulge...that's life...when I was fat, I didn't get that way because I over indulged on a Saturday evening BBQ or a holiday or a birthday indulgence...I got fat because I overindulged regularly and treated every day like an "occasion".

Being able to take a step back and see your diet as a whole and look at the bigger picture will help eliminate these feelings of guilt. Food shouldn't make you feel guilty...if it does, then there's something wrong that IMHO, goes deeper.

I don't really do the cheat day thing but if i feel like i want to eat a certain thing i'll shuffle my daily intake/meals around it so that i can. Denying yourself things is miserable and not necessary! And then just try be a little more active on the days I don't eat as healthy as usual
