Two numbers do most of the work after 50. The PROT-AGE position paper recommends an average daily protein intake of at least 1.0 to 1.2 g per kilogram of body weight for people over 65, rising to at least 1.2 g/kg for those who exercise. And in a dose-response meta-analysis of resistance training in healthy older adults, two sessions a week came out as the single most effective training frequency for strength.
Both numbers point the same direction, and it is not the direction most women over 50 get pointed in. Eat more protein, not less. Lift twice a week, not five times. The thing you are protecting is lean tissue, and lean tissue responds to tension and amino acids, not to restriction.
Why protein needs rise with age
The PROT-AGE group, convened by the European Union Geriatric Medicine Society, set out the physiology plainly: older adults need more dietary protein than younger adults because of age-related changes in how protein is handled. Two mechanisms do most of it.
The first is high splanchnic extraction. More of the protein you eat gets used up by the gut and liver before it reaches your muscles, so less of each meal arrives where you want it. The second is a declining anabolic response, meaning the same amount of protein triggers less muscle-building signal than it did at 30. Add the inflammatory and catabolic load of the chronic conditions that become more common with age, and the requirement goes up from several directions at once.
None of that is specific to women, but the context often is. Rapid weight loss, which is what brings most people to a maintenance app, takes a meaningful share of its total from lean tissue. Doing that in your fifties, on top of the two mechanisms above, is why the protein question stops being optional.
The numbers in the guidance
PROT-AGE's recommendations, as published, run in tiers. At least 1.0 to 1.2 g/kg of body weight per day to help people over 65 maintain and regain lean body mass and function. At least 1.2 g/kg for those exercising and otherwise active. And 1.2 to 1.5 g/kg for most older adults with acute or chronic illness.
Put that in kilograms rather than ratios. A 70 kg woman is looking at roughly 70 to 84 g a day at the lower tier and 84 g or more if she trains. That is three meals each carrying 25 to 30 g, which in practice means protein being the thing you decide first at each meal rather than the thing that happens to be next to the vegetables.
The guidance also recommends both endurance and resistance exercise at individualised levels that are safe and tolerated, and notes that protein quality and timing may matter but that the evidence was not strong enough for specific recommendations. That is a useful caution to carry: the total matters more than the schedule.
Why OffRamp uses a higher number
OffRamp's protein floor is 1.6 g per kilogram of goal weight, rounded to the nearest 5 g. For a 70 kg goal that is 110 g a day. That sits above PROT-AGE's general range, and the reason is who the app is for.
Two deliberate choices sit inside that formula. It uses goal weight rather than current weight, so the number does not shrink as you lose and does not inflate if you are carrying more than you want to. And it is a floor rather than a target, which means there is no upper bound to breach and no sense of having overshot.
There is also no calorie target in the app anywhere. That is not an oversight. In maintenance, and especially after a GLP-1, a calorie figure can be met comfortably while lean tissue quietly goes. The protein floor and the strength sessions are the two things that bear on composition, so those are the two things the app asks about. How to regain muscle after weight loss covers the rebuilding side.
Two sessions a week, not five
The dose-response meta-analysis in Sports Medicine pooled resistance training trials in healthy older adults and found training improved muscle strength substantially, with a mean standardised effect of 1.57 across 25 studies. Effects on muscle size were much smaller, at 0.42 across nine studies, which is worth knowing: the strength and function gains arrive before and exceed any visible change.
When the authors isolated single training variables, the most effective values were two sessions per week, two to three sets per exercise, and seven to nine repetitions per set. The authors were careful about the methodological limits of the underlying trials, so treat these as a well-supported starting point rather than a precise prescription.
Two sessions is the number OffRamp defaults to, and all three of its plans are built as two 20 minute sessions a week with four exercises each: bodyweight with no equipment, a pair of dumbbells, or resistance bands. If you have no kit and no gym, resistance bands build strength comparably to weights across eight pooled trials, so that is not a compromise.
What menopause changes and what it does not
Menopause changes where fat is stored and how quickly it accumulates, and it accelerates bone loss. What it does not change is the response to resistance training or the usefulness of protein. The mechanisms by which muscle is kept are the same before and after.
What shifts is the cost of neglecting them. Bone and muscle decline together, and both respond to loading. We cover the fat-gain side in why weight gets harder at menopause, the bone side in does losing weight cause bone loss, and the longer arc in preventing sarcopenia.
The one real exception
PROT-AGE names a specific exception, and it deserves to be stated rather than buried. Older people with severe kidney disease, meaning an estimated GFR below 30 mL/min/1.73 m2 and not on dialysis, may need to limit protein intake. For that group the higher-protein advice does not apply, and the number is a clinical decision.
For everyone else, the kidney worry is largely inherited from that exception being generalised to healthy people. We went through the evidence in is too much protein bad for your kidneys. If you have any kidney involvement, or you are unsure, ask your doctor what your number should be before raising it.
What to actually track
Three things, and nothing else. The protein floor, daily. Two strength sessions, weekly. And the weight trend as a 7 day average rather than a morning reading, because single-day swings in your fifties are just as meaningless as they were in your thirties.
OffRamp's Regain Radar only reports drift when that 7 day average sits 2 percent or more above your baseline on seven consecutive days, with a louder alert at 4 percent held the same way. The point of waiting a full week is that nothing short-term can trigger it. A birthday, a holiday, a bad week of sleep: none of those move it. A genuine trend eventually does, and by then you have a week's notice rather than a year's regain.
That is the whole system for this age group. Protein high enough to matter, two sessions to supply the signal, and a trend slow enough to be trustworthy.
