ZORBS13 has very good questions, as it's difficult to assess what's going on if we don't know what your workouts consist of, the intensity, what you are eating, how you are sleeping, or other factors like stress and what's going on in your life.
I'm strength training and doing an hour of cardio 2 days a week, and I notice that I'm more tired from that intensity and need to be sure to eat really healthy and nutrient-dense foods after those workouts as well as get good sleep. I also do 2 days of just an hour cardio and 2 days of an hour walk. That hour walk has no impact, meaning I can eat 1200 calories on those days and feel fully energized and like I've gotten enough nutrients. Most days I eat 1500, sometimes even 2000, and I'm actually losing weight more quickly than I expected (I'm 5'10 and losing more than 2 lbs a week most weeks). (Of course, I realize that one will lose weight more quickly at a heavier weight, so if I were at, say 10 lbs from an absolute ideal weight goal like 165 for me personally, I'd probably be more like 1/2 lb loss per week.) I think we might work much harder or eat much less than we actually need to to achieve our goals!
I'm intuiting here, and I sense your workouts are intense and you might not be fueling your body as you need to. It is not uncommon to train too hard and eat too few of calories OR over indulge due to hunger for nutrients and wind up eating even more than the calories you just burned. Both will not give you the results you are wanting.
I would recommend choosing whatever feels best to you (as opposed to choosing from fear or concern). This might mean cutting back on how many days a week your are working out or it might mean doing less intensity or time on your workout days. Be willing to experiement. If you choose what feels good, both for your mind as well as your body, you're more likely to keep doing it!! Maybe start to track what you do and how your energy is and choose those workouts where afterward and/or the next day you feel most energized. Best of luck.
