"I Love Fitness, But I'm Burnt Out"

I'm a 34-year-old man, and I've been involved in sports for most of my life. For the past two years, I've been consistently going to the gym, doing weight training regularly. I usually try to work out three times a week—one day for chest, one for back, and one for legs. And when I'm at the gym, I really push myself and give it everything I've got.

But lately, I’ve completely lost my motivation.
I don’t feel like doing fitness anymore.
I don’t want to go to the gym, I’m tired of tracking protein, and I don’t even want to deal with meal prep.
To be honest, I can't even hit the recommended protein intake. I weigh 78 kg but probably get around 100 grams of protein per day at best.

Fitness used to be something I loved. At one point, it was a passion.
But now it feels like it's draining me more than it's feeding me.

Even though I still like it, I feel like I’m on the verge of quitting fitness altogether.

What would you recommend at this point?
