So you are eating around 120 grams of carbs but, do not count the 1.5 lbs of veggies? That could be an extra couple hundred calories depending on the type.
I would set you calorie counter to track net carbs and add the veggies you eat.
I would keep the calories at 1500 and track all your food. I like to start women at Bodyweight x 14 for maintenance. 136x14= 1904-500= 1500 calories
100 g protein
66 g fat
125 g carbs
If possible I would add another weight training session instead of the HIIT training.
If you want to save time you can make the 3rd session a circuit and if you want to focus on certain areas of the body you can do.
Wed: Lower Body
Fri: Full body circuit it should only take about 30 min.
Keep reps higher. 8-12 reps you may try going 15 reps on the circuit day. Women are better suited to higher reps as they have better endurance and can handle more volume. They are not as efficient when going low reps and working closer to their 1 rep maxes.
I would not do HIIT training and only do cardio 2x a week a 30min walk or bike ride would be enough.
Studies have shown that women are better adapted to steady state cardio. HIIT training offers no real benefit aside from saving time and in can interfere with recovery especially since you are going lower carb.
