Is Crossfit the best option for what im looking for?

Hey everyone

Im 29 male, 100 kg (220 lb), 5'7 (1,70 cm) and in my town (i dont live in US) the only affordable Crossfit places have none of those deadlifts of whatever those bars with weights are called. They just keep jumping on boxes, ropes and running outside the gym.

Im FAT and i need to lose weight, im kind of unmotivated to go to a regular gym cause there is no one to correct the moves and stuff.

I was really thinking Muay Thai would be a good option to lose weight (and learn some decent self defense) and i saw Crossfit but im kind of a very introverted guy and just wanna do my workout in peace and most Crossfits people are together doing stuff like really happy etc.

Anyway, what path should i go? I just wanna lose weight and gain some muscles. I know about diets and stuff but what option would be best considering that i go to a decent place with help from coaches):

• Crossfit

• Gym

• Muay Thai?

Thanks.
