Protein recommendations have changed and not everyone is happy about it. Here's what the new federal protein guidelines actually mean for your health, and why the pushback is missing the point.
A recent PBS article argued that doubling the current protein guidelines would push people toward junk food and processed products. But as a cardiologist, Dr. Bret Scher explains why that concern, while understandable, is misplaced. The real issue isn't the target. It's the message around how to hit it.

Protein debate and core thesis
- The protein debate is a grocery-cart issue, not just a technical guideline dispute.
- A recent PBS article says the new federal protein target is unnecessary and will push people toward junk food.
- That take is misleading because a higher protein target can improve health when it is built from whole foods.
The old rule and its limit
- The old rule was 0.8 g of protein per kilogram of ideal body weight.
- That number was built around nitrogen balance: enough intake to avoid losing muscle.
- 0.8 g/kg is the floor for basic maintenance, not the ceiling for growth, training, strength, or aging well.
- Healthy adults without elevated metabolic demands were the baseline for the old number.
Why the new target is different
- The new target, 1.2 to 1.6 g/kg of ideal body weight, is meant to address real-world metabolic needs.
- The goal is not protein bars, sweet protein cereals, protein snacks, or ultra-processed food with a protein halo.
- The plant-based-food trend already showed how a health halo can turn into ultra-processed fake meats and packaged products.
- The answer is food literacy plus a better protein target, not keeping the target low.
What eating more protein should mean
- More protein comes from whole foods: eggs, chicken, meat, fish, beans, and lentils.
- Protein package wording does not make a processed product healthy.
- The practical rule is to seek protein in real food, not wrappers or bars.
Why protein matters metabolically
- Protein improves satiety, and satiety lowers the pull toward sugary processed snacks.
- Protein improves body composition by helping the body preserve muscle and preferentially lose fat.
- Resistance training strengthens this body-composition effect, even when the training dose is modest.
- Higher protein intake supports glucose control, insulin sensitivity, and healthier body composition.
- Those outcomes matter for cardiometabolic health because muscle, glucose handling, and insulin function shape long-term risk.
Who needs special attention
- Teenagers, athletes, and older adults have higher metabolic demands than the healthy sedentary adult behind the old baseline.
- Growing teenagers need protein for development.
- Training athletes need protein for adaptation and recovery.
- Older adults need protein to preserve mobility and resist muscle loss.
Plant and animal protein practicality
- Plant proteins can fit into a healthy diet.
- Plant proteins usually deliver less bioavailable protein per calorie and per food weight than animal foods.
- Hitting 1.2 to 1.6 g/kg from beans and lentils alone can require a large food volume.
- Animal foods make the target easier to reach with whole foods.
- Animal and plant sources can both be part of the real-food path.
Bottom line
- The new protein target is sound when applied through whole foods.
- The old 0.8 g/kg target was about avoiding decline, not thriving.
- Better guidance means raising protein while steering people away from processed protein-branded foods.

If you view everything politically... you will see everything has politics in it, but that doesn't diminished the value in data.
And if you don't trust the US, here are other options:
If we dig into the US dietary guidelines - https://cdn.realfood.gov/Scientific%20Report.pdf we can see their rational: Page 56 - The Scientific Foundation for the Dietary Guidelines for Americans, 2025–2030, Chapter 6 -
It's a worthwhile read.
to be fair, almost all the data and interventions are done on high carbohydrate populations, so in a ketogenic context the protein benefit may be higher at lower doses.
