How much protein do you really need?

We can't get enough of the stuff, says a new report, and this is what the right daily amount of protein looks like, meal by meal


Apparently we’re obsessed by protein. Sales of protein drinks, cottage cheese and yoghurts are up according to the Waitrose annual food and drink report. Step into your local supermarket or café and you might notice a new category of products spreading across the shelves. While protein bars and low-carb options are nothing new, they’ve been joined by a wide range of protein-enriched foods from pasta and wraps to breakfast cereals and drinks. The sheer volume of these products indicates that many of us are making more of an effort to incorporate protein into our meals and snacks – and it looks like we can’t get enough of the stuff.

It’s not difficult to see why there’s such a buzz around protein. After all, there’s an increasing body of research extolling the power of protein: experts claim it can aid weight loss, build muscle, banish cravings and improve our overall wellbeing. One study found that people following a high-protein diet lost 53 per cent more body fat than a group eating a normal amount of protein but consuming the same number of calories. Other research found that simply increasing protein intake from 15 per cent to 30 per cent of total calories made overweight women eat 441 fewer calories each day without trying. Research also indicates that a high-protein diet can help the body to repair after injury.

However, data from the British Nutrition Foundation indicates that we’re already exceeding the guideline amount set out in the UK Government’s healthy eating model, The Eatwell Guide. This recommends a daily protein intake of 0.75g per kilo of bodyweight, which works out at 56g/day for men and 45g/day for women (based on body weights of 75kg for men and 60kg for women), but on average men are currently consuming about 85g, and women about 67g per day.

As a result, not everyone agrees that eating more protein is a good thing. Research from the University of Chicago found that just six weeks following a very high protein diet can increase the risk of kidney stones and impair the body’s ability to absorb calcium, increasing the risk of bone loss in the long term. Dr T Colin Campbell, author of The Future of Nutrition, argues that an excess of animal protein (from meat, eggs and dairy) can also increase the risk of a number of serious health conditions, including cancer and diabetes. It’s well documented that eating lots of red meat can cause bowel cancer, as well as being linked to an increased risk of cardiovascular disease. In fact, a 2018 study by Finnish researchers found that high-protein diets can increase the risk of heart failure in older men by as much as 49 per cent.

With so much contradictory evidence and conflicting advice, it’s hard to know what to do for the best. So we asked the experts to help us cut through the confusion.

How many grams of protein should I eat a day?

Not everyone agrees with the data from the British Nutrition Foundation. “For best function, we need to be looking towards 100g of protein per day, and for some people up to 120g,” says Dr Clare Bailey, author of The Fast 800 Keto Recipe Book. “On the whole, we’re not eating enough protein in our diets, particularly among groups who eat a lot of ultra-processed foods. It’s important to eat enough because we don’t store protein in the body in the same way that we store fat or carbohydrates, so we need it on a daily basis. It’s vital for just about every function such as supporting strong bones and muscles, immunity, repair and maintaining a healthy weight and metabolism.”

Is it harmful to have too much protein?

It’s hard to have too much of the stuff. “The vast majority of us are under-eating protein, not over-eating it,” says French biochemist Jessie Inchauspé, founder of Glucose Goddess and author of Glucose Revolution. “There’s nothing to fear when it comes to protein – it’s a healthy, essential part of our diet.”

If you seriously max out on protein, there can be side effects, but you have to eat a lot. “There can be problems where the body can’t process large amounts of protein and the kidneys struggle to break it down,” says Prof Tim Spector. “But for that to be an issue you would have to go to four or five times the recommended amount, which is very hard to do. Most people can cope with doubling the amount of protein in their diet without any problems. If you eat too much, you’ll probably just pee it out, or else it will be stored as fat.”

Why some need more protein than others

The other thing to bear in mind is that the amount of protein we need increases with age: from the age of 50 we start to lose muscle, so our protein requirements increase – we need more of it to maintain muscle mass and strength, and some groups need more than others.

Additional protein can be particularly beneficial for women. The Women’s Health Initiative study found that a higher protein intake of around 1.2g per kg of body weight was associated with a 32 per cent lower risk of frailty and better physical function. “We don’t digest and process protein as well as we age,” explains Dr Bailey. “There’s even evidence to suggest that simply adding more protein during the menopause can significantly improve symptoms.”

More protein is also beneficial for pregnant women and athletes who want to gain muscle mass and strength when training.

“You might need more protein if you’re very active, on a restricted diet, or if you’re sick or elderly and not eating enough overall,” explains Prof Spector. “So if you’re vegan, or if you’re a teenage bodybuilder who is on a strict diet, or you’re aged 80 and you’re not eating well, it pays to be a bit more careful.”

Protein helps you lose weight

Eating the right sources of protein can also help you regulate your hunger hormones.

“Getting an adequate amount of protein stabilises glucose levels, increases satiety and reduces cravings,” explains Inchauspé.

Dr Bailey agrees. “The main issue is that the vast majority of us are just not eating enough quality protein, and relying on sweet and starchy processed foods instead.”

What are the main high protein foods?

“It’s best to have good-quality protein in every meal,” says Dr Bailey. “That means eggs, meat, fish, full-fat Greek yoghurt, cottage cheese, nuts and seeds. If you can afford to eat high-welfare or organic meat that’s probably more nutritious, and it’s better for the environment but expensive. I’m a big fan of frozen mackerel, frozen vegetables and tinned fruit.”

Prof Spector agrees that the type and quality of the protein you eat really matters. “If you’re eating very low-quality meat in ultra-processed food and ready meals you might as well swap that for legumes,” he says. “You won’t notice the difference and it’s better for your health. Eating meat every day is associated with heart problems and cancer but there’s no evidence that eating very small amounts of high-quality unprocessed meat is a problem.

Protein from plant-based sources

It’s also important not to overlook other food groups.

“The real danger for me is that people who have high-protein diets have less fibre because they’re not eating plants. That’s really bad for them and means they’re going to get more heart disease.

“The safest sources of protein that everyone agrees are good for you – and good for your heart – are nuts, seeds, beans and legumes. I’d like people to realise that there are proteins in plants, in mushrooms and spinach – and you can get this from a diverse diet. That’s the best way.”

All of those foods are vegan, and much healthier than lots of the food marketed at vegans, which is quite processed.

For Spector, the solution is to eat a varied diet. He says: “If you stick to the advice in ZOE and in my book about eating a whole range of diverse plants you’re highly unlikely to have a protein deficiency because you’ll be getting different types of beans in there, you’ll be mixing those with different whole grains, and it’s that mix that gives you the right balance.”

“If you are struggling to get enough protein into your diet, protein bars and shakes can be a good idea, but make sure they’re unsweetened. The best sources are whey protein or pea protein,” says Inchauspé.

Does this author seriously think she cut through the confusion?! This article is a mash-up of random advice, but not from protein researchers. In this forum, where most members want to lose weight, she should have stopped here:
Other research found that simply increasing protein intake from 15 per cent to 30 per cent of total calories made overweight women eat 441 fewer calories each day without trying. Research also indicates that a high-protein diet can help the body to repair after injury.. Most common advice I read now is a minimum of 100g protein per day or 30g per meal. At 72, I use 40% protein and feel healthier than I did on very low carb, with higher protein and higher micronutrients from vegetables, dairy and fruit. It can be both.

While it is possible to use vegan proteins "However, you must be more intentional to ensure you get the protein you need without excess energy. For example, you’ll need four times as much energy to get the same amount of protein from chickpeas vs egg whites." To say nothing of the digestive impact of eating 2.6 cups of chickpeas!

"Getting at least 30 grams of protein per meal is a common recommendation in health and nutrition circles to increase satiety and maintain stable blood glucose levels. Getting at least 30 grams of protein per meal is crucial for maintaining muscle mass and supporting overall health"

Such articles are about confusing us further!

In the midst of the low fat craze I remember protein was demonized, since it's scanty on a plant-based diet. I even read a book claiming I should try to eat as little protein as possible to dodge breast cancer.

But I always get sick if I don't eat enough. I was not convinced by the book.

Scaring people away from protein is old hat to us low carbers, of course
