Numbers first: eight · 1,200 kcal.
I would rather over-plan the first cycle and simplify later.
I am prepared to do the work if someone can tell me which work matters.
How do I make this decision on evidence rather than on feel?
Eight sessions a week against 1,200 kcal a day — 8400 kcal for the week — and at that intake the binding constraint is almost never the session count. Protein at 4 kcal per gram is the reason: 100 g a day is 400 kcal, 33 per cent of 1,200, and 2800 kcal of the 8400 for the week spoken for before anything else is eaten. 8 sessions also has to be recovered from on 1,200 kcal, and recovery is the first thing an energy deficit takes. Load matters more than frequency here: the stimulus that preserves mass is mechanical tension, so keep the weight and cut the volume rather than the reverse. None of this is medical or dietary advice.
Compound movements give the most stimulus per unit of recovery, which matters more when recovery is the limiting resource.
Protein timing matters far less than protein total, but a serving within a few hours either side of training is a free optimisation.
Training close to failure — one to three repetitions in reserve — is sufficient. Training to failure adds fatigue disproportionately to stimulus and is a poor trade when recovery is constrained.
Volume dose-response meta-analyses place most of the hypertrophy benefit below about ten to twenty weekly sets per muscle group, with diminishing returns above.
Consistency beats optimisation by a margin nobody wants to hear.

Visit GL BiochemStart with frequency and total weekly sets per muscle group, because those two variables explain most of the outcome and everything else is refinement.
Session performance is the practical readiness signal. Two consecutive sessions where loads drop at matched effort usually means recovery, sleep or intake rather than programming.
Beginners retain the ability to gain muscle in a moderate deficit for several months; trained individuals should expect maintenance and be satisfied with it.
The caveat is that programme design is individual, and anyone with joint, cardiac or metabolic constraints needs a professional rather than a forum.
In a deficit, maintaining performance is progression. Reframe it and stop being discouraged.
Answer first: the objective in a deficit is retention, not growth, and retention needs load maintenance and adequate volume rather than progression.
Appetite suppression reduces training fuel as well as protein, and low-carbohydrate sessions feel much worse than they perform. Judge by load, not by feel.
Two sessions per muscle group per week outperforms one at matched volume in most of the published comparisons, mainly through better session quality.
Load-matched comparisons show that maintaining intensity preserves strength and lean mass in a deficit better than reducing load and increasing repetitions.
Published averages conceal wide individual response variation, particularly in older trainees.
One to three reps in reserve. Failure costs more than it returns here.
