agreed with the first paragraph - OP your cals are very low, combined with that cardio it is disaster waiting to happen (unless you have no care about the quality of your muscles or muscular retention)
as for the podcast however - "and notice how catabolic cardio especially running is" - is this what you took from that?
I gave it a listen since I'm in my office doing some paperwork, and this is not quite what I heard lol
do not confuse the term "cardio" to be all-inclusive and indicative of all forms of cardio activity...however, running itself, and especially excessively performing running combined with caloric deficit, is quite catabolic .... this is nothing earth-shattering, as you simply need to look around at long-distance runners and notice their almost universally lean yet muscle-less physiques .. compare this to short-distance sprinters however, and you will see a much different look .. and even this podcast differentiates between for example running, and something like cycling..and again differentiating between HIIT, and LISS
if you are going to attempt to help ppl then try not to generalize your statements so much, you are very habitual about that from seeing many of your posts of advice to others
may also help YOU if you state your own understanding of principles and advice to ppl, rather than simply quoting links and copy & pasting quotes from other ppl (yes layne not withstanding); then, maybe you can get feedback on whether or not you are really on the right track with your understanding and knowledge about things
Layne's knowledge and clients success > a generic gym jockey that posts on these forums, he actually studies this stuff for a living with Dr Wilson in a lab, that is why i posted it for him to understand the benefit and negatvies to running and how catabolic it truly is, and how cardio can play a massive part in a diet towards being beneficial and also negative towards that individuals progress. It is meant to help him
What works for me, wont work for this OP, since the human body is not a textbook. it was a general statement, and also some advice that this person can take with a grain of salt.
I took a lot more from that podcast,
Can aide in fat loss when combined with resistance training.
Prevents protein synthesis.
Blunts hypertrophy
Longer duration of cardio is detrimental to hypertrophy
Low intensity cardio blunts the size of muscle due to the need for muscle type for long duration training
Low intensity cardio can lower metabolism; metabolic adaption. Non-fat loss after long durations.
Cycling causes the least muscle loss compared to uphill walking; almost no muscle damage from cycling; easier to recover from cycling; less damage to muscle compared to running
Running stunts hip flexion; cycling benefits hip flexion which is used in performing squats

Doing sprints lose over 50% more body fat (6-30 sec sprints) compared to 1 hr walk at 3mph.
High intensity what you want to do, not low/moderate intensity; low intensity drops your metabolic rate; high intensity raises metabolism for up to 24 hrs after.
High intensity training is not catabolic; pump can be so extreme it can literally hurt (good thing), muscle pump (swelling) is anabolic; can looker better from performing high intensity sprint sessions than doing squats
Fasted cardio - overall fat loss effects, there is no difference; eat so that you have fuel for high intensity cardio; low intensity good for a short break from doing HI cardio
sorry
