When fat makes up 20% or less of daily calorie intake, the body produces less testosterone, estrogen, and growth hormone.
See the technical phrasing
Fat intake at or below 20% of total energy intake reduces the production of testosterone, estrogen, and growth hormone.
When fat intake is very low, the body has less cholesterol and fatty acids to make testosterone, estrogen, and growth hormone. This causes the cells that produce these hormones to work less efficiently, resulting in lower levels of all three hormones.
