The particulars: two · 800 kcal.
I am at the decision point and I would rather think it through than improvise.
I would rather spend money on measurement than on redundancy.
What does a sensible plan look like, and what are the decision points?
Two sessions a week against 800 kcal a day — 5600 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, 50 per cent of 800, and 2800 kcal of the 5600 for the week spoken for before anything else is eaten. Two to three hard sessions is enough stimulus to defend lean mass; the literature stops improving much past that even at maintenance intake. 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.
The relevant constraint is recovery: a deficit reduces recovery capacity, so the sensible adjustment is volume down slightly and intensity held.
Around ten hard sets per muscle group per week is the region where most of the retention benefit is realised; more produces diminishing returns and, in a deficit, a recovery cost.
Load is the retention signal. Reducing weight and adding repetitions preserves the workout and weakens the stimulus, which is exactly backwards for this objective.
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.

Browse resultsThe short version: two to four sessions weekly, roughly ten sets per muscle group per week, loads maintained, effort close to but short of failure.
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.
Beginners retain the ability to gain muscle in a moderate deficit for several months; trained individuals should expect maintenance and be satisfied with it.
Compound movements first, because recovery is the scarce resource.
Answering this needs to know training history, because a beginner in a deficit can still gain and an advanced trainee cannot.
Protein timing matters far less than protein total, but a serving within a few hours either side of training is a free optimisation.
The relevant detail is that 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.
The caveat is that programme design is individual, and anyone with joint, cardiac or metabolic constraints needs a professional rather than a forum.
One to three reps in reserve. Failure costs more than it returns here.
The honest answer is that almost any structured programme performed consistently beats an optimised programme performed sporadically.
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.
Frequency studies generally favour twice-weekly over once-weekly per muscle group at equated volume.
Nothing here is medical advice.
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.
Two sessions per muscle group per week outperforms one at matched volume in most of the published comparisons, mainly through better session quality.
Published averages conceal wide individual response variation, particularly in older trainees.
Ten sets per muscle group per week, twice weekly, loads held. That is most of it.
