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.
