How Much Protein Do You Actually Need? A Straight Answer
You've probably seen two numbers, and they don't agree.
One says 46 grams a day. The other says 130. Both are quoted confidently, often in the same week, and the gap between them is large enough that one of them must be useless.
Here's what's actually going on, and a number you can use.
The RDA is a floor, not a target
The official recommendation in most countries is 0.8 g of protein per kg of body weight per day. For a 65 kg woman that's about 52 g. That's where "46–50 grams" comes from.
The thing almost nobody explains: the RDA is defined as the amount sufficient to meet the needs of nearly all healthy people — it's the intake at which you're not deficient. It was never designed as the amount at which you function best.
It's a floor. Useful for preventing a deficiency disease. Not a target for someone who trains, is over forty, is trying to hold onto muscle, or simply wants to not be starving at 10 AM.
What the research actually supports
Most sports-nutrition and protein-metabolism research lands in the range of 1.2–2.0 g per kg per day, depending on what you're asking of your body.
A rough guide:
| Situation | g per kg/day | 65 kg example |
|---|---|---|
| Sedentary, RDA floor | 0.8 | ~52 g |
| Generally active | 1.2–1.4 | ~78–91 g |
| Regular resistance training | 1.6–2.0 | ~104–130 g |
| Over 50, preserving muscle | 1.2–1.6 | ~78–104 g |
| In a calorie deficit | 1.6–2.2 | ~104–143 g |
Two patterns worth noticing. Older adults need more, not less — the muscle-building response to a given dose of protein becomes blunted with age, so it takes more to produce the same effect. And eating in a deficit raises the requirement, because protein is what protects lean mass while you're losing weight.
Where does that put most people? Somewhere between 1.2 and 1.6 g/kg is a sensible working target for a generally active adult who isn't training for anything specific. For a 65 kg person, roughly 80–105 g a day.
What that looks like in food
Grams per kg is abstract. Here's the same thing as things you'd actually eat:
| Food | Protein |
|---|---|
| Chicken breast, 150 g | ~46 g |
| Greek yoghurt, 170 g pot | ~17 g |
| 2 large eggs | ~13 g |
| Tin of tuna | ~25 g |
| Cottage cheese, 100 g | ~11 g |
| Lentils, 1 cup cooked | ~18 g |
| Tofu, 100 g firm | ~17 g |
| Whey protein, 1 scoop | ~20–25 g |
| Slice of bread | ~3 g |
| Handful of almonds | ~6 g |
The useful realisation from that table: hitting 100 g takes deliberate structure. It doesn't happen by accident on a day of toast, a sandwich and pasta.
The distribution problem
Total daily protein isn't the whole story. When you eat it matters too, and this is where most people's day has a hole in it.
A typical pattern looks like 5 g at breakfast, 20 g at lunch, 45 g at dinner. Same total as an evenly distributed day, very different outcome — muscle protein synthesis responds to individual doses, and there's a ceiling to how much a single meal can stimulate.
Research on older adults has found that a higher protein intake at breakfast and lunch is associated with a higher total daily intake — front-loading doesn't just redistribute, it tends to raise the total.
The practical version: aim for 25–30 g per meal rather than banking it all for dinner. For most people the gap is breakfast, by a mile. More on why that specific meal matters in our breakfast protein guide.
Common questions, answered honestly
Can you eat too much protein? For healthy kidneys, the evidence for harm at intakes up to around 2 g/kg is weak to non-existent. If you have existing kidney disease, that's a conversation with your doctor.
Do you need protein powder? No. It's food that's convenient, not food that's magic. It's useful exactly when whole food isn't practical — which for most people is breakfast.
Is plant protein worse? Not worse, different. Most plant proteins are lower in leucine and some are incomplete, so the effective dose is higher. Variety solves most of it. More on protein quality here.
Does it all have to be in one sitting? No — and it shouldn't be. Spreading it is more effective.
Frequently asked questions
How much protein per day for a woman? The RDA floor is 0.8 g/kg. Most research supports 1.2–2.0 g/kg depending on activity, age and whether you're in a deficit. For a 65 kg woman, roughly 80–105 g is a reasonable target.
Is 100 g of protein a day enough? For most active adults under about 80 kg, yes — it sits comfortably in the evidence-supported range.
How much protein at breakfast? 25–30 g is the commonly cited target, and breakfast is where most people fall furthest short.
Do I need more protein as I get older? Yes. The muscle-building response to a given dose becomes blunted with age, so requirements go up rather than down.
Does protein help with hunger? It's the most satiating macronutrient. One trial found 10 g of whey before a meal reduced next-meal intake by 9.4%.
Is the RDA wrong? Not wrong — just widely misread. It's the amount that prevents deficiency, not the amount that optimises anything.
Where Franky fits
The gap for almost everyone is breakfast, and the reason is practical rather than motivational — nobody wants to cook at 7 AM.
Franky Protein Iced Coffee puts 10 g of whey protein per scoop into something you were already making. Two scoops gets you to 20 g, which lands in the range that matters for a meal.
That's the whole proposition, and we'd rather state it plainly than dress it up: it isn't a complete breakfast and it won't hit your daily target on its own. It closes the specific gap between nothing and something, at the time of day when most people have nothing.
