Older adults can roughly double their daily protein intake, from about 0.8 to 1.6 grams per kilogram of body weight, over about 4 months if they get guidance from a dietitian. This shows that they can eat much more protein than the standard recommendation.
See the scientific wording
Community-dwelling older adults (mean age ~73 years) can successfully increase their habitual dietary protein intake from approximately 0.8 to 1.6 g/kg body weight per day through a 17-week dietary counseling intervention, indicating that substantially greater than recommended protein intakes are achievable in this population.

Randomized Controlled TrialHuman2022
The study showed that older people can indeed double their protein intake from about 0.8 to 1.6 grams per kilogram of body weight in 17 weeks when they get help from a nutritionist.

That doesn't mean it's settled — it just means no study has tested the opposite.
Quality-weighted scoring: we follow the GRADE framework — each study is rated High, Moderate, Low, or Very Low based on study design, methodology rigor, and risk of bias. A single high-quality RCT can outweigh several weaker observational studies.
Scores reflect study quality, not just count.
Older adults can learn to eat more protein when they get help from a coach. This coach gives them advice and support, which makes them more motivated and changes their eating habits. Over time, they eat more protein without feeling overly full.

Mechanism
1 studyWhen older adults get help from a coach, their brain becomes more interested in protein-rich foods, so they eat more of them. After a while, their stomach adjusts so they don't feel too full, making it easier to keep eating the right amount.
Older adults can learn to eat more protein when they get help from a coach. This coach gives them advice and support, which makes them more motivated and changes their eating habits. Over time, they eat more protein without feeling overly full.
Dietary counseling provides structured guidance and social support, which engages cognitive processes that increase attention and motivation toward protein-rich foods.
The increased motivation activates reward pathways in the brain, enhancing the reinforcing value of protein-rich foods.
As the person consistently consumes more protein, the gastrointestinal tract adapts by modulating gut hormone secretion, reducing satiety and allowing for comfortable maintenance of the higher intake.

What Would Prove This
Per GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this claim, ordered from strongest to weakest.
Systematic Review of Dietary Counseling Interventions to Increase Protein Intake in Community-Dwelling Older Adults
A systematic review and meta-analysis of randomized controlled trials (RCTs) that examine dietary counseling versus usual care or no intervention in community-dwelling older adults (mean age ~70 years or older), with outcomes measuring changes in dietary protein intake (g/kg/day) over at least 12 weeks.
Randomized Controlled Trial of Dietary Counseling vs. Usual Care for Protein Intake in Community-Dwelling Older Adults
A randomized controlled trial with 200 community-dwelling older adults (aged ≥65 years) randomized to receive individualized dietary counseling (e.g., by a registered dietitian, focusing on protein-rich foods) or standard care (e.g., a leaflet with general dietary advice). Protein intake (g/kg/day) is measured at baseline and at 17 weeks via 3-day food diaries or 24-hour recalls. The study should be double-blinded where possible (though blinding of participants is difficult) and include a comparison of the change in protein intake between groups.
Prospective Cohort Study of Dietary Counseling and Protein Intake Changes in Older Adults
A prospective cohort study following a group of community-dwelling older adults (≥65 years) who voluntarily engage in a dietary counseling program (exposed) and a comparable group who do not (unexposed). Protein intake is assessed at baseline and after 17 weeks. Statistical adjustment for variables such as age, sex, BMI, health status, and baseline protein intake would be used to estimate the effect of counseling.
Case-Control Study of Factors Associated with Successful Protein Intake Increase in Older Adults
A case-control study where cases are community-dwelling older adults (≥65 years) who, after a 17-week dietary counseling program, achieved a ≥80% increase in protein intake (e.g., from <1.0 to ≥1.6 g/kg/day), and controls are those who did not achieve this increase. Retrospective data on counseling attendance, educational materials, baseline protein intake, health status, and other potential predictors are compared.
