Huberman emphasizes the importance of clarifying what we mean when discussing "nutrition." A pivotal study by Stanford's Chris Gardner in 2018 demonstrated that, over a year-long period, weight loss was essentially unaffected by whether participants followed a low-fat or low-carbohydrate diet, as long as their caloric intake was below maintenance levels. This indicates that caloric balance is the primary driver of weight change, though other factors such as hormone levels and metabolic health also play critical roles.
