The Health Advice That Sounds Smart but Doesn’t Hold Up, According to Dr. Mike Varshavski

Dr. Mikhail Varshavski, popularly known as Dr. Mike, is a board-certified family medicine physician who has built a massive following by debunking wellness myths that sound logical but aren't supported by science. In an era where social media influencers often prioritise aesthetics and trends over clinical data, Dr. Mike focuses on the basics: evidence, nuance, and common sense. He frequently points out that the most effective health advice is often the least glamorous, and focuses on habits rather than hacks.

The Fallacy of the Supplement Foundation

One of the most persistent ideas in modern wellness is that more pills equal more health. It is easy to assume that if a vitamin is good for you, a concentrated supplement must be better. Dr. Mike frequently warns that the supplement industry is loosely regulated compared to pharmaceuticals, meaning what is on the label isn't always what is in the bottle. Unless you have a clinically diagnosed deficiency, your body is remarkably good at getting what it needs from a balanced diet. Taking megadoses of vitamins can actually do more harm than good; for instance, excess fat-soluble vitamins can build up in your system, and too much of certain minerals can strain your liver and kidneys. As Dr. Mike often says, "If your diet is solid, supplements should be supplemental, not foundational."

Fatigue is Biology, Not Laziness

Hustle culture has turned exhaustion into a badge of honour, often suggesting that if you’re tired, you just need more caffeine or more willpower. Dr. Mike pushes back hard against this, reframing fatigue as a vital biological signal rather than a lack of character. Chronic tiredness is usually a symptom of a deeper issue, such as poor sleep quality, chronic stress, or an underlying medical condition such as anaemia or thyroid dysfunction. According to sleep medicine research, chronic sleep deprivation mimics the effects of being legally intoxicated. It impairs your judgment, slows your reaction time, and messes with your hormones. Dr. Mike’s advice is simple but often ignored: you cannot out-hustle a lack of recovery. Rest is a non-negotiable health behaviour, not a reward you earn only after you’re burnt out.

Looking Healthy vs. Being Healthy

We live in a visual culture where "health" is often sold as a specific look, usually involving lean muscles and low body fat. Dr. Mike consistently warns his audience that aesthetics are a poor proxy for internal health. You can be thin and have dangerously high cholesterol, or you can have a higher body fat percentage and excellent cardiovascular markers. Clinical data highlights a group of people often referred to as "metabolically unhealthy normal-weight" individuals. These people look fit by societal standards but have the same risk factors for heart disease and diabetes as those with clinical obesity. Dr. Mike encourages focusing on internal metrics like blood pressure, blood sugar, and energy levels rather than what you see in the mirror.

The Problem with One-Size-Fits-All

Social media loves a "magic" diet or a specific workout routine that "changed everything" for one person. However, Dr. Mike emphasises biological variability. Your genetics, your environment, and your stress levels all dictate how your body responds to a specific change. What makes your favourite influencer feel great might make you feel sluggish or sick. Research confirms that people can have wildly different glucose responses to the exact same food.6 This is why Dr. Mike advocates for personalisation over trends. Effectiveness in health is almost always dependent on context. Instead of copying a celebrity’s routine, he suggests paying attention to how your own body responds to different foods and movements.

The Paradox of Over-Optimisation

In the age of wearable tech, it’s easy to become obsessed with optimising every second of your life. We track our steps, REM sleep, heart rate variability, and calories. Dr. Mike has warned that this constant tracking can paradoxically lead to worse health outcomes by increasing anxiety. If your sleep tracker tells you that you had a "poor" night of sleep, the resulting stress can ruin your day more than the actual lack of sleep would have.

Stress is a significant risk factor for heart disease. If your pursuit of health is causing chronic anxiety, it isn't healthy. Sustainable habits always beat temporary perfection. Health should be a tool that supports your life and allows you to do the things you love; it shouldn't become a second full-time job that controls you.
