HIIT for fat loss?

I am also 5’3” and for me I have found that diet combined + HIIT means weight loss. Highly recommend it. Usually it means 500 calorie burn. HIIT needs to be intense as someone else mentioned. I use to run with a group of girls who ran faster than I did and that did the trick. That was 10 years ago though! Now, at age 45 I find it is more difficult and trying to loose about 10lbs. Just recently started to incorporate 3 HIIT sessions per week. Orangetheory training 2x week, running stairs (weights in between stair sets), 1-2 runs (3 miles at a moderate pace) and a long walk plus 1-2 days of weight training. And of course food tracking between 1200-1500 /day. Anxious to see how it pays off. We all respond differently so see how your body responds!
