Please be careful with oxygen, you cannot handle breathing 100% oxygen for long, it starts to cause all kinds of acute health issues all throughout your body.
The biggest hacks are all mental though, and to know what you're actually up against. As hyped up as the fitness industry makes it all seem, there's nothing particularly special about fitness, you just gotta do it.
The majority of weight loss is dietary, but without exercise you can't really enable that diet process properly. So make sure you love what you're doing for exercise and that gives you all the necessary context for the diet.
Just dieting because you kindof should is a losing strategy. Dieting because you want to get faster on the bike, or because you want to be a beast at rock climbing, or because you want to look good doing laps, are all really great motivators. Also, to be frank, if all you want out of it is to have better sex, that's hardwired into our brains to motivate us to do crazy stuff, no harm in wielding that power.
Trying to convince yourself to diet when your only goal is to look good while sitting at the computer is a losing strat.
Oxygen exposure is best seen in terms of absolute molecules for oxygen poisoning. If you are 90m water depth, 2.1% oxygen is the same as 21% at the surface. At ~0.2 atmospheric pressure, 100% oxygen would be about the same as at surface.
8 psi is 0.54 atmospheric pressure, so breathing in 100% oxygen under that pressure would be similar to a 54% nitrox mix at surface. Not as bad as 100% at surface, but might still be something that a doctor would monitor for potential signs. It is important to remember that people tolerance for oxygen can vary between people, and that Astronauts is a heavily selected group in term of fitness and health.
