Every Woman Should Do This Before Bed To Lose Belly Fat

Summary

Dr. Michael Diamond and Cass present a four-part bedtime routine intended to support better sleep and body composition, particularly during perimenopause and menopause. They emphasize consistency over perfection.

The video’s claims about belly-fat loss are not guaranteed. Some of the research discussed measured sleep or muscle-related outcomes rather than belly fat directly.

Four-part bedtime routine

1. Create a cooler sleep transition. Take a comfortable hot shower or bath for at least 10 minutes, about 1–2 hours before bed (the presenters suggest roughly 90 minutes). They say that warming the skin and then cooling down may help the body prepare for sleep. Dim the lights in the evening and consider breathable bedding. For night sweats, they suggest a short shower and allowing more time to cool down.

2. Use breathing to wind down. Put your phone away and try the described 4-7-8 breathing: inhale for 4 seconds, hold for 7, exhale for 8, then hold for 4. Repeat for about 10 rounds or 5 minutes. If you wake at night feeling activated, they also describe a “physiological sigh”: take a deep inhale through the nose, add a brief second inhale, then exhale slowly.

3. Consider magnesium carefully. The video discusses magnesium bisglycinate or L-threonate, and suggests magnesium-rich foods such as pumpkin seeds, spinach, black beans, and almonds. The presenters give a supplement range of 200–350 mg, suggest taking it with the last meal, and advise reducing the amount if it causes morning grogginess or digestive issues. They recommend consulting a clinician about supplements, particularly if taking antibiotics or bone medication. Chamomile tea is suggested as a caffeine-free option for winding down.

4. Plan an evening protein serving. They suggest plain cottage cheese or Greek yogurt as a source of slowly digested casein protein, with optional berries or ground flaxseed. They recommend having the last meal about 3 hours before bed and avoiding flavored versions with added sugar. The presenters acknowledge that much of the casein research they cite involved younger men and measured muscle-related outcomes, not belly-fat loss.

Other bedtime tips

Protect the last hour before bed by avoiding work, screens, intense exercise, stressful conversations, and alcohol. The presenters also suggest charging your phone outside the bedroom.

They recommend trying the routine consistently for a few weeks and tracking waist or clothing fit as well as scale weight.

Health caution

The presenters say this is not personal medical advice and recommend discussing changes with a healthcare professional, especially for people who are pregnant, have diabetes or use blood-sugar medication, or have liver or kidney conditions.
