If your gym workout involves high-intensity strength training,
you need enough glucose to do it.  If your normal diet is very
carb restricted, your glycogen reserves will be low.
High-intensity effort is anaerobic, involving the fast-twitch
muscle fibers.  Fat cannot be burned anaerobically; the
fast-twitch fibers absolutely need glucose.  If your reserves are
low,  you will simply run out of glucose before it can be
replenished from gluconeogenesis, and you will "run out of gas"
during your workout.  I.e., you won't be able to do as many reps
or sets as you otherwise could.
