The Claim
In adults aged 65 and older, consuming 162 grams per day of minimally processed lean pork within a nutrient-dense, plant-forward diet for 18 weeks results in no greater loss of lean body mass than an isocaloric diet rich in lentils.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In adults aged 65 and older, eating 162 grams of lean pork daily for 18 weeks while following a nutrient-dense, plant-forward diet leads to the same amount of lean body mass loss as eating an equivalent number of calories from lentils.
See the scientific wording
In adults aged 65 and older, consuming 162 grams per day of minimally processed lean pork within a nutrient-dense, plant-forward diet for 18 weeks does not lead to greater loss of lean body mass compared to an isocaloric diet rich in lentils, suggesting that red meat may help preserve muscle mass during weight loss in aging populations.
When older adults eat protein-rich foods like pork, their bodies break down the protein into amino acids that circulate in the blood. These amino acids signal muscle cells to keep building new muscle proteins, even when the body is burning more calories than it takes in. This keeps muscle mass from breaking down too much, no matter if the protein comes from pork or lentils.
What the research says
1 studyIn a study with older adults losing weight, eating pork every day didn’t make them lose more muscle than eating lentils — and they might have lost a little less. So pork seems just as good as lentils for keeping muscle when losing weight.
