Can lifestyle changes actually fix low testosterone before TRT?

What did @drvictorchan actually say?

Dr. Victor Chan, a licensed naturopathic doctor with two decades of practice, made two core claims in this video. First, that TRT "should literally be the last resort" for men whose testicles can no longer produce enough testosterone on their own. Second, that most men pursuing TRT have not addressed the underlying causes of their low testosterone before starting treatment. He frames the video as a setup for future content on natural hormonal optimization.

To be clear, he did not recommend any specific supplement, dose, or protocol. He did not make diagnostic claims or attack TRT as inherently harmful. The message was broadly cautionary, and that context matters when evaluating it.

Does the science back this up?

Partially, yes. But the framing that TRT should be the "last resort" is more ideological than clinical, and the evidence deserves a closer read than that phrase suggests.

The Endocrine Society's 2018 clinical practice guidelines recommend TRT for men with confirmed hypogonadism, meaning consistently low serum testosterone plus symptoms, not as a last resort after exhausting lifestyle options, but as a primary treatment when the diagnosis is established. That is a meaningful distinction. For men with secondary hypogonadism driven by obesity, sleep apnea, or metabolic dysfunction, lifestyle intervention is genuinely supported by evidence. A 2013 study by Camacho et al. in the European Journal of Endocrinology found that weight loss significantly increased testosterone in obese men with low-T. A 2015 randomized trial by Hoyos et al. in the Journal of Clinical Endocrinology and Metabolism showed that treating obstructive sleep apnea improved testosterone levels. So lifestyle-first is sometimes evidence-based, but it is not universally appropriate, particularly in primary hypogonadism where the testes themselves are the problem.

What did they get wrong (or right)?

He got the general principle right: many men pursuing TRT have modifiable risk factors that deserve attention first. Obesity, sleep deprivation, alcohol overuse, and chronic stress all suppress testosterone via well-documented mechanisms, primarily through elevated cortisol and aromatization of testosterone to estrogen in adipose tissue. That is real physiology, not wellness-influencer noise.

Where the video oversimplifies is in the "last resort" framing. For a man in his 50s with primary hypogonadism, a low LH, and a total testosterone consistently below 300 ng/dL with symptoms, telling him to try lifestyle fixes first is not just unhelpful, it can delay treatment that improves bone density, cardiovascular risk markers, and quality of life. Bhasin et al., in a 2010 landmark trial published in the New England Journal of Medicine, showed measurable improvements in lean mass and sexual function from TRT in older hypogonadal men. Lifestyle intervention alone would not replicate those outcomes for that population.

He also uses "crank up your testosterone levels" as a slightly pejorative framing, which implies supraphysiologic use without actually accusing anyone of it. That rhetorical move is a little slippery.

What should you actually know?

If your testosterone is low, the first question is why. That requires bloodwork, not a TikTok video. Total testosterone, free testosterone, LH, FSH, SHBG, and prolactin tell you whether the problem originates in the testes, the pituitary, or the hypothalamus. Without that picture, "address root causes first" is advice that could apply to everyone or no one.

Lifestyle changes do move the needle for some men. A 2016 meta-analysis by Corona et al. in the Journal of Sexual Medicine found that weight loss interventions raised total testosterone by roughly 2.9 nmol/L on average in overweight and obese men. That is meaningful, but it is not equivalent to TRT for men with organic hypogonadism.

The broader point worth keeping: TRT is not a lifestyle upgrade. It is a medical treatment for a medical condition. Men who pursue it without a confirmed diagnosis, or who use it to push testosterone above physiologic range, face real risks including infertility, polycythemia, and cardiovascular strain. Those risks are worth knowing before anyone frames TRT as either a miracle or a last resort.

• Get a proper diagnosis before deciding anything.
• Address sleep, weight, and alcohol first if those are factors.
• Understand that "natural optimization" has a ceiling for men with primary hypogonadism.
• Ask your provider to test LH and FSH, not just total testosterone.
