Menopause and perimenopause: calorie and protein needs
There is no separate calorie equation for menopause. What changes is body composition, sleep and activity — and those change the inputs to the same equation everyone else uses.
General information only, not medical advice and not a diagnosis. These are population reference values; a doctor or registered dietitian is the person who turns them into something specific to you.

It is worth being blunt: no reference body publishes a menopause-specific energy requirement. EFSA and WHO/FAO set adult values by age, sex, body size and activity, and menopause is not one of the inputs. That does not mean nothing changes. It means the change runs through the inputs rather than through the formula.
Three things move. Lean mass tends to fall through midlife, and lean mass sets resting energy expenditure — so the same body weight at 55 usually has a slightly lower requirement than it did at 40. Fat distribution shifts toward the abdomen, which changes how the same weight looks and how some risk markers read without necessarily changing the energy arithmetic at all. And sleep disruption, which is one of the most commonly reported symptoms, quietly reduces daily movement in a way that almost nobody logs.
The iron column is the one genuinely welcome change. Once menstruation stops, the reference intake falls from 16 mg a day to 11 mg. It is the only requirement on this site that gets easier with age, and it is a useful counterweight to the general impression that everything gets harder.
Symptom management — hot flushes, sleep, mood, hormone therapy — is a clinical conversation, not a nutrition one. This page stays on the energy and protein arithmetic and hands the rest to your doctor, who can weigh your history against options this site is not allowed to discuss.
The adjustment for this stage
No separate energy reference value — menopause changes body composition and symptoms, not the equation.
PAL 1.5 is a lightly active adult. Sleep disruption during this stage often pulls real activity down, which is one of the underrated routes by which the requirement changes.

The equation this page uses
BMR (men) = 10 × weight(kg) + 6.25 × height(cm) − 5 × age + 5
BMR (women) = 10 × weight(kg) + 6.25 × height(cm) − 5 × age − 161
Daily target = BMR × 1.50Worked through for the middle row of the table below: a woman of 75 kg and 168 cm at age 52 has a Mifflin-St Jeor BMR of about 1 379 kcal. Multiplied by PAL 1.50 that is 2 069 kcal, which is the daily estimate.
Worked example: by height and weight
| Body weight | 155 cm | 162 cm | 168 cm | 175 cm |
|---|---|---|---|---|
| 55 kg | 1 647 | 1 712 | 1 769 | 1 834 |
| 65 kg | 1 797 | 1 862 | 1 919 | 1 984 |
| 75 kg | 1 947 | 2 012 | 2 069 | 2 134 |
| 85 kg | 2 097 | 2 162 | 2 219 | 2 284 |
| 95 kg | 2 247 | 2 312 | 2 369 | 2 434 |
Worked example: how age moves it
| Age | 55 kg | 65 kg | 75 kg | 85 kg | 95 kg |
|---|---|---|---|---|---|
| 45 | 1 821 | 1 971 | 2 121 | 2 271 | 2 421 |
| 48 | 1 799 | 1 949 | 2 099 | 2 249 | 2 399 |
| 52 | 1 769 | 1 919 | 2 069 | 2 219 | 2 369 |
| 56 | 1 739 | 1 889 | 2 039 | 2 189 | 2 339 |
| 60 | 1 709 | 1 859 | 2 009 | 2 159 | 2 309 |
What changes if your activity is different
| Activity level | What it describes | kcal a day |
|---|---|---|
| PAL 1.4 | Sedentary or low activity — desk work, little planned exercise | 1 931 |
| PAL 1.6 | Moderately active — some walking, light training two or three times a week | 2 206 |
| PAL 1.8 | Active — on your feet at work, or training most days | 2 482 |
| PAL 2.0 | Very active — physical job plus training, or high training volume | 2 758 |
Protein for this stage
There is no menopause-specific protein reference value. The 1.0-1.2 g/kg band shown here is the same muscle-preservation target published for older adults, applied because loss of lean mass is the mechanism that matters here too.
| Body weight | Protein, lower g/day | Protein, upper g/day | kcal from the lower figure | Share of the daily estimate |
|---|---|---|---|---|
| 55 kg | 55 | 66 | 220 | 12% |
| 65 kg | 65 | 78 | 260 | 14% |
| 75 kg | 75 | 90 | 300 | 15% |
| 85 kg | 85 | 102 | 340 | 15% |
| 95 kg | 95 | 114 | 380 | 16% |

The nutrients that matter most here
- Calcium. Bone loss accelerates around and after the menopausal transition. EFSA's adult reference intake is 950 mg a day.
- Vitamin D. Paired with calcium for bone; EFSA publishes an adequate intake of 15 µg a day for adults, and northern countries add winter advice on top.
- Iron. Goes the other way. Once periods stop, the reference intake falls from 16 mg a day to 11 mg — one of the few requirements on this whole site that drops with age.
- Protein. Supports the lean mass that sets your resting energy requirement, which is the mechanism behind most of what people notice at this stage.
- Magnesium. Frequently discussed for sleep and cramps around menopause. The evidence for symptom relief is weak; the reference intake exists regardless.

Nutrient reference values are population figures. This page never tells you to take a supplement or how much of one to take — that is a decision for a clinician who can see your blood work and your medicines.
What to actually do
- Prioritise resistance training. It is the only lever that acts directly on the lean mass driving the requirement.
- Keep protein at the muscle-preservation end of the range rather than the minimum.
- Treat sleep as an activity intervention as well as a comfort one — poor sleep quietly reduces daily movement.
- Take symptoms and treatment options to a doctor; this page deliberately does not cover them.
Frequently asked questions
Does menopause lower my calorie needs?
Not directly. Requirements shift because lean mass and activity shift. There is no menopause term in any published energy equation.
Do I still need as much iron?
Once periods stop, the reference intake falls from 16 mg a day to 11 mg for women — one of the few requirements that decreases.
Which equation is this based on?
Mifflin-St Jeor for the resting figure, multiplied by a physical activity level of 1.50, with no flat increment for this stage.
Can I use this instead of seeing a professional?
No. These are population reference values. A midwife, doctor or registered dietitian is the only person who can turn them into a plan for you.
