Wrong answer.

Cutting is never needed to gain mass.

Fat people should not cut unless they have some desire to go from fat to skinny fat.

Yes, this is a good thing and yes this is a definitive answer.

If they work out and pack more muscle they burn more calories than doing stupid cutting as well as plain cardio and slower rate of fat loss. of course, this doesn't mean follow a powerlifting training style.

Actually, this has been proven a lot on shows like "Biggest Loser".

Fat people should focus on doing circuit training or super sets.

Nope, that's a broad generalization and bro-science.

Fat people can indeed build muscle on below maintenance as they have plenty of fats to fuel their burn as well as to break down for recovery. Not to mention beginner gains can DEFINITELY be made on crappy diets as long as someone is working hard enough in the gym. The person just needs to eat sufficient protein to ensure a steady supply of muscle-building nutrients.

Yes cutting should involve cardio - since you already mentioned no or very little weight training. Or else what, they should eat below maintenance and wait an eternity for the fat to come off?

No offence, but if your avatar is current, it looks like you sure could use some cardio as well. 

For TS, fat people have a lot of bodyfat (~duh) so if somehow they choose to bulk, they'll get much much bigger and possibly fatter. So, it will better for them to cut first, probably to 15%~ish bf then start to bulk.

When did I say they need to bulk?

They don't need to cut either. That's a sure fire way to fail. Cutting is hard - even for advanced bodybuilders, never mind fat people that are just beginning to learn how to eat properly and starting working out. They need a good, filling diet if they are going to work hard in the gym and keep their mind of the sweets and mcdonalds. You ever cut before while still working out hard? Physically draining and tiring, can't imagine what it will be like for a beginner, with serious DOMS and body aches as well.......and not enough nutrition to recover properly.

They need to do a proper recomp - which will give them the best results. Eat right, at or just sliiiiightly below maintenance and push hard in the gym.

Also, fat people, their body weight and leverage allows them to ramp up to heavier weights - much smarter than doing a cut and then only focus on strength.

Recomp.

Simple. Eat till full but clean up diet - no fast food and no sweets (or replace sweets with diet coke).

Work out as hard as you can in the gym - make sure increase the weights every week. Stay away from stupid programs like Starting Strength.

Profit.
