Leading the change to better periods and hormones
How a low carb or keto diet can affect female hormones and the menstrual cycle. Adequate glucose intake is required to signal the hypothalamus and LH pulsatility. Insufficient starch intake can, therefore, suppress luteinizing hormone and ovulation.
This is my open letter to every clinician, personal trainer, and blogger who offers health advice without thinking about the importance of ovulation and natural ovulatory menstrual cycles.
Dear Sir,
Your restrictive dietary advice may cause young women to stop ovulating which is a problem because ovulation is how women make hormones.
That makes ovulation an essential part of human physiology and not just for making babies. Ovulation is not optional. Thank you.
Polycystic ovary syndrome (PCOS) cannot be diagnosed by ultrasound because polycystic ovaries are not cysts. They’re follicles or eggs which are normal for the ovary.
It’s normal for all women to sometimes have a higher number of follicles. It’s normal for young women to always have a higher number of follicles because young women have more eggs. That’s why PCOS cannot be diagnosed by ultrasound. At the same time, PCOS cannot be ruled out by ultrasound because it’s possible to have normal-appearing ovaries on ultrasound and still have the hormonal condition PCOS.
High-dose fructose can cause or worsen insulin resistance, abdominal weight gain, fatty liver, heavy periods, and PCOS.
High-dose fructose comes from table sugar (sucrose), high-fructose corn syrup, and even some natural sweeteners such as agave, coconut sugar, dates, dried fruit, and fruit juice.
Whole fruit is healthy and does not cause insulin resistance because 1) whole fruit contains only low-dose fructose, and 2) fruit also provides beneficial nutrients, fibre, and polyphenols.
Every time I tweet my concern about women losing their periods to a low-carb or keto diet, I get a lot of angry responses.
“It’s purely anecdotal,” men explain to me. “There’s no known mechanism, so it can’t be happening.”
Except it is happening. Ask anyone who works with young menstruating women. Or not menstruating, as the case may be.
