Most people never even look at their kidney number.
And when they do… they don’t know what to do with it.
My last GFR was 74.
At nearly 58 years old, that technically puts me in the “Stage 2 CKD” category.
Sounds concerning, right?
Not so fast.
This is where nuance matters.
Kidney function does decline with age. A GFR in the 70s can be completely stable and appropriate, especially without other markers like protein in the urine.
But here’s the real issue:
👉 Most people are never told what their GFR means
👉 Even fewer are told what actually influences it
👉 And many get oversimplified advice like “cut protein” without context
Let’s clear that up.
Yes, very high protein intake can stress the kidneys over time, especially if function is already reduced.
But that doesn’t mean protein is the enemy.
In fact, going too low can backfire, particularly as we get older, where maintaining muscle becomes critical.
The goal is not “low protein.”
It’s appropriate protein.
For most people in this range, that means:
✔️ Moderate intake (not high, not low)
✔️ Focus on overall metabolic health
✔️ Control blood pressure
✔️ Reduce excess sodium
✔️ Avoid ultra-processed, hyper-palatable foods
Here’s the part almost nobody talks about:
Kidney health is far more influenced by blood pressure, metabolic health, and environment than by whether your protein came from plants or animals.
So if you’ve ever been told to just “cut protein” without a deeper conversation…
You’re not getting the full picture.
Ask your doctor:
• What’s my GFR trend over time?
• Do I have any albumin in my urine?
• What’s actually driving my kidney function?
Because a single number without context is just that…
A number.
And understanding it properly could change everything.

Thursday thoughts with Dr Tom…

Reality check. We are not going to medicate our way out of the metabolic epidemic.
Retatrutide is impressive.
So are semaglutide and tirzepatide.
They work. No question.
But step back for a second.
Prediabetes isn’t going down.
At best, we’re treading water. More likely, we’re still drifting in the wrong direction.
So what’s going on?
Part of it is how we’re using these medications, treating them like shortcuts instead of tools.
Part of it is access, a meaningful portion of the population simply isn’t getting these drugs due to cost, coverage, or lack of consistent care.
But zoom out further and the bigger issue becomes hard to ignore:
We’re asking people to live in a way the system isn’t built to support.
I’ve lived this.
Standing in a McDonald’s parking lot, looking at a $5 value meal on the sign, then walking across to Meijer where a pint of blueberries costs more than that.
I still bought the blueberries.
And I remember thinking very clearly, I can afford to make that choice.
A lot of people can’t.
That’s not a willpower problem. That’s design.
And if everyone suddenly followed the advice and demand for fruits and vegetables surged, what happens?
Prices go up. Access gets tighter. The people already under the most socioeconomic pressure get pushed further out.
In many communities, access isn’t just limited, it’s structurally constrained.
Now layer on policy.
The United States Farm Bill and decades of agricultural incentives have helped shape a system heavily oriented toward inputs that feed calorie-rich, refined, and hyper-palatable (CRRAHP) foods.
That didn’t happen by accident. And it’s not going to fix itself by accident either.
So yes, medications like retatrutide are powerful.
And approaches like The Flex5 Lifestyle are some of the most practical ways to help individuals navigate the current environment.
But let’s be honest:
They can’t carry this alone.
If we actually want to move the needle, this is generational work:
• Policy change
• Smarter agricultural incentives
• Making real food more accessible and affordable
• Education that actually reaches from early school through medical training
Call it a public health Marshall Plan.
Because right now, we have a system that produces disease upstream and asks medicine to clean it up downstream.
That’s not a strategy. That’s a loop.
And until we break that loop, we should expect more of the same. Sadly but respectfully, that’s where Reality Meets Science.

21yo and ready to binge eat vs 21+36y (57) healthy and happy.

Dr Tom Rifai is a physician expert in the areas of lifestyle medicine and metabolic health coaching for wellness, weight loss and disease prevention. He has worked with countless patients to reverse or substantially improve their type 2 and prediabetes, heart disease and unparalleled skills in healthy, sustainable weight management. Many physicians claim to be expert in metabolic health, lifestyle medicine and weight management. Exceedingly few have Dr. Rifai's well established experience at the highest levels of multidisciplinary care nor his personal insights as a recovering binge eater (see link at bottom). His evidence based training and clinical approach is one of "lifestyle first, medications only if necessary". Dr Rifai has been elected a Fellow of the American College of Physicians for his leadership in education of physicians and medical students in lifestyle medicine and type 2 diabetes prevention. He recently served as Regional Medical Director of Metabolic Health and Weight Management for the world renown Henry Ford Health System of Metro Detroit, Michigan - helping make unprecedented strides in standardizing and integrating multiple different program offerings throughout the system to one based on a solid, unified curriculum based on his Reality Meets Science® based 5 Keys to optimal wellness, weight loss and disease prevention: 1. Understanding Nutrition 2. Understanding Activity 3."Mind Matters" (psychological and spiritually related issues) 4. Environments (e.g., food, social) and 5. Accountability (e.g., whether to a program like RMS, a hospital based program or even self-monitoring tools like food and fitness apps or groups).
Dr Rifai is founder and President of his health education and wellness company Reality Meets Science® LLC (aka RMS), the mission of which is to translate lifestyle science into powerful, yet practical and sustainable applications for the every day person (tag line: "Lifestyle Science for YOU"). The 5 RMS Keys of healthy lifestyle helps busy, hard working people break down the otherwise challenging process of life saving lifestyle changes into manageable areas of focus. As they operate together when one Key area improves, it typically helps benefit other Key areas of healthy lifestyle (an interdependent superstructure of the most critical distilled components of health and well-being)
Dr Rifai has also been distinguished as a Harvard Medical School continuing medical education (CME) online course director of Lifestyle Medicine on the urgent topic of prevention of type 2 diabetes (course title: "Nutrition and the Metabolic Syndrome" Weblink - CMEonline.Med.Harvard.Edu/Info/Nutrition) Rifai's Harvard CME course educated thousands of health care providers since its release in 2009 and has been in the top quintile of most popular online Lifestyle Medicine CME courses through Harvard Medical School. The course guides and educates doctors and health care providers on evidence based motivational interviewing techniques, practical, achievable but effective and lifesaving lifestyle changes as well as the type 2 diabetes prevention drug Metformin, where evidence justifies its use and potential benefit as an add-on to (not as an alternative to) lifestyle change.
In all of this, Dr. Rifai is not only an expert in the area of therapeutic lifestyle change, but also a patient himself. As aforementioned, he has spent years challenged with depression, binge and nighttime eating. The experiences and journey through such, while maintaining great health thanks to all the blessings in life he has to motivate him to "battle on!" has given him great insight, and humbling modesty, in his becoming an elite lifestyle and health coach. He provides not only great sympathy, but great empathy with the clients and patients he serves. His story on becoming a lifestyle medicine doctor was recently published through the American College of Lifestyle Medicine: https://www.lifestylemedicine.org/page-1863534
