The Willpower Myth

We’re often told we need to “eat less, exercise more” to reach our goals. But the truth is, most people who struggle with their weight have something on the inside that’s impacting their outside. The Weight Biology Kit helps you identify those roadblocks so you can work with your body, not against it.

of our patients find at least one metabolic condition impacting their weight

our kit tests eight key biomarkers to help you gain a deep understanding of your metabolic health and uncover metabolic conditions like: 

Insulin Resistance

Insulin resistance makes it difficult to lose weight due to the overproduction of insulin, a fat-storage hormone. The Weight Biology Kit is the first and only at-home test that identifies insulin resistance early on and gives you next steps to get your levels under control.

Metabolic Syndrome

Metabolic syndrome is a collection of conditions, including issues like high blood sugar or unhealthy cholesterol levels. When you understand how these conditions function together, you can develop a roadmap to gain health, lose weight, and prevent disease.

Unhealthy Cholesterol Levels

High cholesterol can make weight loss challenging and cause other health issues. If your cholesterol levels put you at risk, we can walk you through different ways you can improve your health, like supplementation, medication, and diet changes.

Pre-Diabetes or Type 2 Diabetes

If you’re diagnosed with pre-diabetes or diabetes, we’ll walk you through your risks. But don’t panic—knowledge is power! Diabetes progression can be reversed with the right approach. We’ll recommend lifestyle adjustments you can make to regain your health.

Vitamin B12 Deficiency

It takes energy to tackle these health risks and to commit to daily change. If you know that your Vitamin B12 levels are below average, then we can help you with supplementation.

Thyroid Conditions

If your thyroid gland is not producing enough of the thyroid hormone, you can experience issues with your energy, body temperature, and metabolism. We’ll provide resources to support your thyroid and give you information to discuss with your healthcare team.

“I had tried every diet and weight loss program out there and never had success. SoWell Health helped me better understand my body so I could finally find a plan that would work for me. I’m down 30 lbs and I’ve never felt better.”


Micaela D.

“For years, I felt an unbalance in my body leading to weight gain, but my doctor always told me that my labs were ‘normal’ and I was ‘healthy for my age.’ SoWell’s lab kit helped me realize I have insulin resistance and sleep apnea. Now that I’ve been treated for both, I’ve finally been able to lose weight and feel healthy again.”
