This one has a reasonably settled answer, so here it is. On a suppressed appetite the winning strategy is protein density per unit of volume, not per calorie. Isolate powders, Greek yoghurt and cottage cheese, egg whites, lean fish, and tinned tuna all deliver a lot of protein in a small physical volume. Front-load it: appetite is usually least suppressed in the first hours after waking and worst on the day or two after dosing, so get the majority in early in the day and early in the week.
Counting rather than debating, for once. The debate can happen underneath.
I tracked honestly for two weeks and averaged 68g of protein against a target of about 120g. That gap is the whole problem and no meal plan I have found is written for it.
What I am trying to establish is whether the RDA is the wrong reference entirely during rapid weight loss, and what the actual target should be.
Roughly, people seem to land in one of these:
- Held where they were and waited it out
- Changed one variable and kept everything else fixed
- Changed several things at once and cannot now attribute the result
- Stopped and reassessed from a clean baseline
Say which and say why — the why is the useful half.

Agreed on the target, with the caveat that reference weight and current weight are different numbers. Using current weight at the start of a large loss produces a target that is both unachievable and unnecessary.

This matches mine closely enough to be worth saying so. The RDA is the wrong reference and it is worth understanding why. 0.8 g/kg is the intake at which nitrogen balance is not negative in healthy weight-stable adults — a floor for deficiency prevention, not an optimum, and derived in a population that is not in a deficit. In a substantial energy deficit, protein requirement rises because amino acids are being oxidised for energy and because muscle protein synthesis is blunted. The literature on preserving lean mass during weight loss lands around 1.4 to 2.0 g/kg of reference body weight, which is roughly two to two and a half times the RDA.
Adding the clinical framing, because it changes how the question reads.
DEXA scan update relevant to protein intake:
Scanned at months 0, 6, and 12. Here are the body comp numbers:
| Baseline | Month 6 | Month 12 | |
|---|---|---|---|
| Total mass | 271 lbs | 236 lbs | 198 lbs |
| Fat mass | 101 lbs | 71 lbs | 48 lbs |
| Lean mass | 154 lbs | 150 lbs | 155 lbs |
| Body fat % | 40% | 30% | 22% |
Lean mass preserved — actually GAINED 1-2 lbs thanks to progressive overload + 1.4g/kg protein. The protein intake discussion needs to include body comp data, not just scale weight.
