The protein problem no one talks about

By Slavica - Integrative Wellness Educator

Protein is having a cultural moment.

Protein yoghurt. Protein bars. Protein cereal. Protein water.

If a food can be fortified, someone has done it.

And while protein is absolutely essential, here’s the part missing from the hype:

Most adults already meet — or exceed — their daily protein needs without trying.

(“Most Australians get more than enough protein from food alone.” Better Health Channel, Victorian Government)

When I analysed a normal day of eating, I realised something surprising:

I hit my entire daily protein requirement by lunchtime.

No powders.

No bars.

No “high‑protein” hacks.

Just real food.

And that’s where the protein trend becomes a problem.

A REAL EXAMPLE: MY BREAKFAST + LUNCH

Breakfast

• Veggie mix (zucchini/pumpkin/leek)

• 2 boiled eggs

• 1 slice wholemeal toast

• 30 g feta

Protein: ~25–28 g

Lunch

• Wholemeal wrap

• 75 g tuna

• Cucumber + celery

• 2 tbsp mayo

• Greek-style yoghurt

Protein: ~40–45 g

By 1 pm, I’d already eaten 65–73 g of protein, which is above the RDI for the average woman.

Daily protein requirement for women:

• 46 g/day — Australian NHMRC Nutrient Reference Values

• 0.75 g/kg/day — Swinburne University summary of Australian guidelines

• “Most women need around 46 g/day” Harvard Health Publishing

So, by lunchtime, I was already at 140–160% of my daily needs.

And I wasn’t even trying.

SO, WHAT HAPPENS WHEN YOU ADD MORE PROTEIN?

Once you’ve met your needs, extra protein doesn’t turn into bonus muscle or extra health.

It turns into stress on systems that thrive on balance.

Here are the evidence‑based problems with chronic excess protein.

1. DIGESTIVE STRAIN

High‑protein diets often displace fibre‑rich foods, leading to constipation and sluggish digestion.

“High‑protein, low‑fibre diets can lead to constipation, nausea, diarrhoea, and stomach pain.”

Verywell Health (reviewed by board‑certified physicians)

2. KIDNEY LOAD

Excess protein increases nitrogenous waste, which the kidneys must filter.

“Extra protein intake can tax the kidneys… poses additional risk to people predisposed to kidney disease.”

Mayo Clinic

“People with chronic kidney disease should closely monitor protein intake.”

Swinburne University (nutrition science summary)

3. EXCESS ENERGY → FAT STORAGE

Protein is still energy.

When you eat more than you need, the excess is stored as fat.

“Excess protein is used for energy or stored as fat.”

Mayo Clinic

“Excess energy is stored as fatty tissue.”

Swinburne University

4. CROWDING OUT OTHER NUTRIENTS

High‑protein diets often reduce intake of fibre, antioxidants, and phytonutrients.

“High‑protein diets may cause digestive issues due to low fibre intake.”

Verywell Health

This can affect:

• gut microbiome diversity

• energy levels

• cravings

• hormonal balance

5. CARDIOVASCULAR STRAIN (DEPENDS ON PROTEIN SOURCE)

Animal‑heavy high‑protein diets can increase heart disease risk.

“High‑protein diets high in red meat and saturated fat may increase heart disease and colon cancer risk.”

Harvard Health Publishing

6. NO ADDITIONAL MUSCLE BENEFIT BEYOND A POINT

For muscle building, benefits plateau at ~1.6 g/kg/day.

More than that shows no additional muscle gain.

THE REAL ISSUE: WE’VE LOST OUR SENSE OF “ENOUGH”

The wellness industry loves extremes.

But health isn’t built on extremes, it’s built on appropriate intake, balanced meals, and listening to your body.

Most people don’t need:

• protein shakes

• protein bars

• protein yoghurt

• protein cereal

• protein water

They need adequate protein — not endless protein.

And adequate is surprisingly easy to reach.

THE TAKEAWAY

If you’re an athlete, your needs are higher.

But for the average adult?

You can meet your protein needs naturally, easily, and without turning every meal into a macro spreadsheet.

Sometimes the healthiest thing you can do is simply stop adding more.
