How to Hack Your Hormones and Use Science to Lose Weight and Sleep Better | The Mel Robbins Podcast

KEYPOINTS

• 01

  Women's hormones were left out of medical research for decades.

  Dr. Amy Shah, a double board-certified doctor with nutrition training from Cornell, explains that women were long excluded from medical studies because of fluctuating hormones and possible pregnancy. Inclusion had to be mandated, which she recalls happening around the 1980s. Until then, women were often simply given smaller doses. Even now, she says, studies rarely track how a drug affects estrogen, progesterone or testosterone. When she struggled with her own hormones as a young mother, OB-GYN colleagues admitted they had learned about puberty and pregnancy, and little more than 'it shuts off' about menopause.

  Think of estrogen and progesterone as two sisters.

  Shah describes estrogen as the smart, social, risk-taking sister who can go a bit off the rails, and progesterone as the calm one who says let's stay home and chill. In the years around menopause both decline. Less estrogen can mean less sharpness, less energy, less socialising and quietly moving less. Less progesterone can mean more anxiety, poorer sleep and a feeling that life is out of control, which explains much of Mel's waking in the night.

  Your cycle has phases you can plan around.

  From day 1 of your period to about day 14, estrogen and progesterone rise, so energy and stress resilience are higher. Shah calls this the time to 'train like an athlete, eat like an athlete' and to try intermittent fasting or not eating two to three hours before bed. Testosterone spikes around ovulation, making it a good window for building muscle, or for something that needs confidence, like asking for a raise. Days 21 to 28, the late luteal phase, are when you're least stress-resilient and more insulin-resistant. That's the time to ease off intense workouts and sugar, eat more fiber and protein, and get more sunlight, walks or massages.

• 04

  PMS is a monthly mini-menopause.

  In the week before a period, estrogen and progesterone fall to their lowest point, which is why Shah calls PMS a small version of menopause. The habits that help in perimenopause also help with PMS.

• 05

  Perimenopause is like squeezing an almost-empty toothpaste tube.

  Some months you get a good dose of hormones and feel normal; others you get a splatter or nothing and feel terrible. The hormone drop can start up to 10 years before menopause, often in the mid-40s and sometimes as early as 35. Hot flashes happen because hormones help the hypothalamus regulate temperature. Menopause itself means 12 months without a period. Symptoms often ease five to ten years later as the body adjusts to lower levels, but disease risk, especially heart disease, rises after menopause.

• 06

  Belly fat in midlife has a hormonal reason.

  As ovarian estrogen falls, the body looks for other hormonally active tissue, and fat around the middle produces estrogen. Estrogen also helps preserve muscle. Shah says adults lose up to about 3% of muscle mass per decade, and the loss speeds up in menopause without weight training and enough protein, which explains Mel's 'wings'. Women also tend to become less active without noticing.

• 07

  Hormone therapy helps some symptoms, but not weight gain.

  According to Shah, HRT is good for hot flashes and temperature swings, vaginal dryness and pain during sex, and progesterone replacement can help anxiety. It isn't a treatment for weight gain. Her analogy is that hormones are like gas in a car: if the highway is jammed, more gas won't get you anywhere. Sleep, exercise, weight training and food choices are what clear the traffic. She adds that the old fears about HRT causing cancer have been revised, and that starting close to the onset of perimenopause or menopause seems to give the most protection.

• 08

  Insulin resistance makes old habits stop working.

  Shah explains insulin as the hormone that opens a cell's door to sugar. When cells are already full, they stop answering, blood sugar stays high and the body gets the signal to store fat, while the risk of type 2 diabetes goes up. During menopause, caffeine, alcohol and sugar also raise cortisol at a lower threshold. That's why the same coffee, sugar and glass of wine you always had can now cause trouble.

• 09

  There's no such thing as adrenal fatigue.

  Shah says the adrenal glands don't 'burn out'. Feeling exhausted is a traffic jam across the whole hormone system, involving the thyroid and brain, driven by lifestyle and age-related changes. She also warns that more isn't better with hormones: too much thyroid hormone can cause heart palpitations and arrhythmias.

  You don't need a blood test to diagnose perimenopause.

  Shah calls it a myth that you must have your hormone levels checked. Menopause is diagnosed by symptoms, not by a hormone level. She criticises the 'medical gaslighting' of women who leave with an anti-anxiety prescription and no explanation, and encourages finding a doctor who will look at symptoms in the context of a woman's hormones.
