How do you find HIIT for fat loss?

How effective is this for cutting up? What kind of HIIT do you find best? Thanks

I think HIIT is just one piece of the puzzle. Alot of guys say do complexes like cosgraves 8 but this will cause you injury and major fatigue unless you very fit and can do them properly. I would advise regular interval training on fitness machines, a track or on the road in combination will long distance running or 30 minute workouts on the fitness machines at a good pace (60-65% max heart rate = fat burning / higher than this = endurance/fitness improvement zone).

Ive jus done my morn hiit 15mins at max speed on 1.5 gradient 1min off 30secs off its a real killer!!

It has it's place as part of a varied cardio programme, but variety is the key rather than looking for one 'golden chalice' type of exercise for fat burning.
 
There's a lot of bro science about fat loss and muscle retention with regards cardio types, but the main thing as always is diet and keeping lifting. Any cardio spikes the metabolism and increases fitness - this makes the body more efficient at dealing with the fat content in your diet, and the absorbtion rate of it.
 
The body doesn't work session on session, day on day or even week on week, so the key is to find the overall diet, weights and cardio set up that works best for your cut.

Try 10 mins of sprints after your weights, put your body in a more anabolic state... 1 min on (sprint) / 1 min off (walk)

For me ,whatever anyone says about ,adrenals ,hormones ,muscle tissue wastage etc,
 if I dont do my I hr fast walking 2 or 3 times a week,I start to get a flabby belly.
 
People were getting shredded years ago long before Tabetas,Hiit,burst ,etc.

Doing HIIT for your cardio just leads to mental burnout if your doing it all the time.

HIIT treadmill sprinting 15mins 45s on 45s off 3 times a week, 1 hr SSCV everyday works a treat for me

i quite like to do this
 
monday - hiit -45-60mins
tuesday - sscv 60mins
wednesday - hiit - 45-60mins
thursday - sscv
friday - 30/30 - hiit followded by sscv
saturday - 40mins hit weights followe by 20mins sscv
sunday - off or 40mins sscv 20hiit

Due to time constraints the only conventional HIIT I do is rowing. 
 
The rest of my CV is BW conditioning type stuff like burpees and BW squats. Working well, CV is never more than 15-20 mins and you probably get a better 'metabolic conditioning' effect.
