Is Your Brain Fog Really Menopause? Dr. Sarah McKay Explains What the Research Says
1w ago01:09:29Tap to summarizeBrain fog in perimenopause isn't inevitable decline.Brain fog in perimenopause isn't inevitable decline. It's a systems puzzle, and once you understand what's actually driving it, you can do something about it. In this episode I'm joined by Dr. Sarah McKay, neuroscientist and author of The Women's Brain Book, and we break down the real neuroscience behind why your brain feels different in midlife, what the research actually says about HRT and brain health, and the evidence-based strategies to protect and optimise your cognitive performance. WHAT YOU’LL LEARN • What actually causes perimenopause brain fog (it's not just your hormones) • How night sweats disrupt sleep architecture even when you don't fully wake up • Why anxiety and waking at 3am are early signs of the perimenopause transition • What the research really says about estrogen, progesterone, and testosterone on brain health • Why the progesterone and GABA sleep claim is not what it seems • How your career and daily habits are already shaping your long-term dementia risk • Why your mindset about aging may be affecting your cognitive performance • The daily framework for protecting your brain: sleep, nutrition, strength training, and stress TIMESTAMPS: VALUABLE RESOURCES • Take the BioSyncing Quiz to help you understand what’s actually happening in your body — and how to fix it. 👉 https://biosyncing.scoreapp.com/ A BIG thank you to our sponsor who make the show possible: - MitoQ - Support your cells at the source with MitoQ NAD+ Dual Action, designed to boost NAD levels and help your cells actually use them for steady energy and sharper focus 👉 https://www.mitoq.com and use code ANGELA for 10% off your first order.

Why is belly fat so common in midlife? Perimenopause, Cortisol, and Hormones
2w ago00:09:32Tap to summarizeAngela presents a bitesize episode inn which she explores the physiological changes behind midlife weight gain, focusing on the role of cortisol and the hormonal shifts occurring during perimenopause. They highlight how the decline and fluctuation of oestrogen and progesterone lead to a redistribution of body fat from the hips and thighs to the abdominal area, as the body transitions out of its fertile state WHAT YOU’LL LEARN Hormonal Fat Redistribution: During perimenopause, declining oestrogen levels signal the body to shift fat storage from fertile areas like the hips and thighs to the abdomen. Muscle Mass and Metabolism: Loss of lean muscle mass in midlife significantly slows metabolism, as muscle is a primary "metabolic organ" that consumes glucose and fat for energy. The Importance of Protein: Prioritising high protein intake and sufficient calories is essential for building and maintaining muscle, especially as it becomes harder to do so during perimenopause. GLP-1 Considerations: While GLP-1 medications can aid weight loss, they often suppress appetite so significantly that meeting necessary protein requirements for muscle preservation becomes a major challenge.

The Real Reason Perimenopausal Women Can't Lose Belly Fat (It's Not What You Think)
3w ago00:13:36Tap to summarizeWhy does belly fat suddenly increase in perimenopause, even when you’re eating well and exercising? In this episode, Angela Foster speaks with Cynthia Thurlow about the real drivers behind midlife body composition changes, from hormones and muscle loss to stress, inflammation, and gut health. They explore why cortisol and nervous system dysregulation play such a major role in abdominal fat storage, how the gut microbiome impacts oestrogen metabolism, and the simple strategies women can use to support metabolic health and feel more in control of their bodies again. KEY TAKEAWAYS Muscle loss reduces insulin sensitivity in midlife Chronic stress increases abdominal fat storage The gut microbiome influences oestrogen metabolism Fibre supports hormone detoxification and inflammation reduction Declining oestrogen impacts digestion and bile production Gut health plays a major role in body composition Midlife body composition changes are reversible with the right strategy VALUABLE RESOURCES • Take the BioSyncing Quiz to help you understand what’s actually happening in your body — and how to fix it. 👉 https://biosyncing.scoreapp.com/

Why Eating Tomatoes Shrinks Belly Fat in Perimenopause (The Brown Fat Trigger) | Dr. William Li
Apr 2400:14:21Tap to summarizeDr. William Li explores the fascinating science of brown fat, a specialised type of fat that acts like a cellular furnace to burn off harmful visceral fat. He reveals how a simple daily habit, like eating a single ripe tomato an hour before lunch, can trigger this fat-burning mode, potentially shrinking waistlines and reducing inflammation. From the historical discovery of brown fat in hibernating animals to modern breakthroughs in PET scan technology, Dr. Li explains how we can use elemental eating and cold exposure to optimise our metabolism and reclaim our health. WHAT YOU’LL LEARN Eating one ripe tomato a day, particularly an hour before lunch, has been shown to activate brown fat and can lead to a reduction in visceral fat and waist circumference. Brown fat is packed with mitochondria that burn fuel to generate heat, especially when activated by certain foods or cold temperatures. Tomatoes are rich in bioactives like lycopene and beta-cryptoxanthin, which are absorbed into the bloodstream and directly fire up brown fat cells. Returning to a diet of whole, unprocessed foods allows the body to take full advantage of its natural metabolic hardware.
