How much protein per day do women need?

Adult women need at least 0.83 g of protein per kg of body weight per day, about 50 g for a 60 kg woman, but most active women do better on 1.2 to 2.2 g/kg, which is 72 to 132 g a day at 60 kg. Where you land in that range depends on your goal, training and age.

Protein advice for women is often copied from men's bodybuilding plans or, at the other extreme, stuck at the bare minimum. Neither fits most women. This guide sets out the numbers by bodyweight and goal and explains where each one comes from.

Protein per day for women by bodyweight and goal

The table converts the main evidence-based ranges into grams per day. Use your current body weight. If you carry a lot of excess fat, use a goal weight or a weight that puts you at a BMI around 25 instead, otherwise the targets get unnecessarily high.

Why the minimum is not the goal

The 0.83 g/kg figure is set to cover the needs of nearly all healthy adults to avoid deficiency and keep nitrogen balance. It was not designed to maximise muscle, support training or protect lean mass while dieting. For sedentary women it is a perfectly reasonable floor. For women who lift, run or are trying to lose fat, research consistently points higher.

Protein by goal

General health and light activity

1.0 to 1.2 g/kg is a comfortable target. It sits above the minimum, supports satiety and is easy to reach with ordinary meals.

Fat loss

Aim for 1.6 to 2.2 g/kg. Higher protein helps preserve muscle in a calorie deficit and keeps you fuller on fewer calories. Lean women in an aggressive deficit sometimes go up to about 2.4 g/kg.

Building muscle and strength

1.6 to 2.2 g/kg covers the range where gains in muscle and strength have been observed to level off. Women do not need less per kilogram than men here. Total grams are lower simply because body weight is lower.

Women over 65

Older adults use protein less efficiently, so expert groups recommend more than the standard minimum.

Pregnancy and breastfeeding

EFSA adds about 1 g, 9 g and 28 g of protein a day in the first, second and third trimesters, and about 19 g a day during the first six months of breastfeeding. For most women that means adding a glass of milk, a yoghurt or an extra portion of beans, fish or meat in the second half of pregnancy, not a radical change. Discuss specific targets with your midwife or doctor.

How to hit your number

A 65 kg woman aiming for 1.6 g/kg needs about 104 g a day. Split over meals, that is very manageable:

• Breakfast: 200 g Greek yoghurt with oats and berries, about 25 g
• Lunch: a chicken, tuna or lentil salad bowl, about 30 g
• Snack: cottage cheese or a protein shake, about 20 g
• Dinner: a palm-and-a-half of fish, meat or tofu with vegetables and a starch, about 30 g

Plant-based eaters can reach the same totals with tofu, tempeh, seitan, lentils, beans and soy milk. Aim toward the upper end of the range and mix sources to cover all essential amino acids.

Is high protein safe for women?

For healthy women, intakes up to about 2.2 g/kg have not shown harm to kidneys or bones in research. If you have kidney disease or another medical condition, ask your doctor before raising protein. Going much above the researched ranges does not add muscle; it mainly adds calories and crowds out other foods.

Protein in common foods

Knowing roughly what a portion provides makes the target far easier to hit than counting every gram. Typical values:

• 100 g cooked chicken breast: about 30 g
• 100 g cooked salmon or white fish: about 22 to 25 g
• 2 large eggs: about 12 g
• 200 g Greek yoghurt (plain, 0 to 2% fat): about 18 to 20 g
• 150 g cottage cheese: about 17 to 18 g
• 100 g firm tofu: about 12 to 15 g
• 1 cup (about 200 g) cooked lentils: about 18 g
• 1 scoop whey or plant protein powder: about 20 to 25 g

Combining two or three of these at each meal covers almost any target in the table. If your appetite is small, prioritise the protein part of each meal first.

How protein fits your calories

Protein provides 4 kcal per gram, so 100 g is 400 kcal. On a 1,600 kcal diet that is a quarter of your energy, which leaves comfortable room for carbohydrates, fats, fruit and vegetables. Our macro calculator turns a calorie target into grams of protein, carbs and fat in one step.

Signs you may be eating too little protein

Persistent hunger between meals, slow recovery from training, losing strength while dieting and a diet built mostly around bread, pasta and snacks can all point to low protein. None of these is diagnostic on its own, but if several apply, tracking protein for a few days is a quick check. Many women who believe they eat a lot of protein land closer to 50 to 70 g a day once they measure, which is fine for health but low for training or fat loss goals.
