Intermittent fasting is often promoted online as a solution for: weight loss insulin resistance inflammation and hormone balance So it is understandable that many women with PCOS wonder whether they should try it too. Some women do report benefits from fasting approaches. But for many others, especially those already struggling with: cravings fatigue stress emotional eating or inconsistent eating patterns fasting can sometimes make symptoms feel worse rather than better. This

If you have PCOS and often feel: hungry soon after eating exhausted by the afternoon constantly craving sugar or stuck in cycles of “being good” all day then overeating at night blood sugar instability may be playing a bigger role than you realise. Many women with PCOS are told they have “insulin resistance”, but are never properly shown: what this actually feels like in everyday life. Instead, they are often given: confusing diet advice lists of foods to avoid strict meal pl

If you’ve ever been told to “just cut carbs” to manage your PCOS, you're in the right place. Many women I work with arrive frustrated, having already tried a low-carb diet, keto, or sugar detox, only to feel worse: tired, moody, bloated, or stuck at the same weight. So why does this happen? And is going low-carb really the best approach for PCOS? In this post, we’ll look at: Why low-carb diets may backfire in PCOS The link between blood sugar, cortisol and hormone imbalances

If you have PCOS and constantly feel exhausted, struggle with evening cravings or feel stuck in cycles of “starting again tomorrow”, poor sleep may be playing a much bigger role than you realise. Many women with PCOS focus heavily on: what to eat supplements exercise routines weight loss strategies But sleep is often the missing piece. And not just because it affects energy. Poor sleep can influence: appetite regulation cravings blood sugar balance stress hormones emotional e

If you have PCOS and often feel like eating becomes harder to manage in the evenings, during stressful periods or after trying to “be good” all day, you are in the right place. Many women with PCOS feel frustrated by patterns like: emotional eating after work constantly thinking about food snacking when stressed or overwhelmed feeling out of control around sugar or comfort foods eating well all day then overeating at night using food to cope with exhaustion or low mood Afterw

If you have PCOS and feel like your body is constantly working against you, you may have heard the term “slow metabolism”. It is often used to explain: weight gain difficulty losing weight low energy stubborn cravings But this explanation is usually oversimplified. With PCOS, metabolism is not just about how many calories you burn. It is much more closely linked to: how your body regulates energy how stable your blood sugar is how well you recover from stress how consistently

If you have PCOS and feel like you’ve tried every “quick fix” under the sun, only to end up back at square one, you are in the right place. Many women describe the same pattern: starting a strict plan on Monday cutting back food, carbs or calories feeling in control for a few days then experiencing intense cravings feeling tired, irritable or overwhelmed overeating in the evenings or at weekends feeling like they’ve “failed” and starting over again Over time, this can feel ex

Why Is Protein Important for PCOS? If you have PCOS and often feel hungry soon after breakfast, struggle with energy crashes, or find yourself reaching for snacks by mid-morning, your breakfast may be part of the problem. Many typical breakfast foods such as cereal, toast, pastries and fruit juice are high in carbohydrates but low in protein. While they may provide a quick source of energy, they often don't keep you feeling satisfied for long. Protein helps slow digestion, su

Many women with PCOS notice that symptoms often feel worse during periods of stress. You may recognise patterns like: stronger cravings during busy weeks more fatigue when overwhelmed disrupted sleep during stressful periods worsening skin symptoms before deadlines feeling more emotionally reactive around food irregular cycles after stressful life events This is not “all in your head”. Stress can affect multiple systems involved in PCOS, including: blood sugar regulation appe

Why sugar cravings with PCOS feel so hard to control Have you ever found yourself thinking, “I just need more willpower around sugar…” This is one of the most common things women say when they’re struggling with PCOS. Cravings can feel intense, persistent, and frustrating, especially when they seem to undo a full day of “eating well”. But in most cases, cravings are not about a lack of discipline. They’re a biological response. And once you understand what’s driving them, the

“I’m eating well… so why do I still feel stuck?” This is something I hear often. You’re trying to make better choices. You’re being more mindful with food. You might even be following what you’ve been told is a “healthy diet”. But you’re still dealing with symptoms like: Ongoing sugar cravings Energy dips throughout the day Stubborn weight gain that isn’t shifting Feeling like your body isn’t responding the way it should It can feel frustrating and confusing. Especially when

Many women with PCOS experience symptoms that seem to affect multiple areas of the body at once. You may notice: bloating after meals fatigue and low energy cravings and appetite changes skin flare-ups digestive discomfort feeling puffy or inflamed irregular bowel habits or symptoms that worsen during stress. At first, these symptoms can feel completely unrelated. But increasingly, research suggests the gut may influence several systems involved in PCOS, including: inflammati

If you have PCOS and struggle with fatigue, low mood, frequent infections or difficulty losing weight, vitamin D may be one piece of the puzzle worth exploring. Vitamin D deficiency is common in the UK, particularly during the autumn and winter months when sunlight exposure is limited. Research also suggests that low vitamin D levels may be more common in women with PCOS compared with the general population. While vitamin D is not a cure for PCOS, maintaining healthy levels m

Many women with PCOS reach a point where they feel like they have tried everything. Often this includes cycles of: cutting out food groups reducing carbohydrates avoiding dairy tracking calories or macros intermittent fasting or constantly restarting “healthy eating” plans. While these approaches may feel productive in the short term, over time they can unintentionally lead to a different issue: not eating enough of the nutrients your body needs consistently This doesn’t mean

Do Women With PCOS Need Snacks? One of the most common questions I hear is whether women with PCOS should snack between meals. The answer is that it depends. Many women benefit from focusing on three balanced meals first, especially if meals are low in protein or leave them feeling hungry shortly afterwards. However, snacks can still have a place. A planned snack can be useful if: There is a long gap between meals You are physically hungry You have been active You are trying

Why this balanced bowl works for PCOS Many women with PCOS know the frustration: You eat "well" and still feel hungry soon after. Energy dips hit mid‑afternoon. Cravings take over when you least expect them. Often, the missing piece isn’t food quality alone, it’s meal structure. With PCOS, meals that lack enough protein, fibre or healthy fats can lead to: Rapid blood sugar spikes Energy crashes Strong cravings Appetite that feels out of control This balanced bowl is built to

If you have PCOS, you’ve probably heard that balancing blood sugar is important. But knowing what to do in theory and understanding how your body actually responds to food, stress and daily life are very different things. This is where functional health tests like DUTCH hormones cycle mapping, DNA and Continuous Glucose Monitoring (CGM) can be a powerful learning tool. For many women I work with, especially those struggling with stubborn weight gain, cravings, energy crashes

Bloating and digestive symptoms are extremely common in women with PCOS. You may notice: ongoing bloating after meals discomfort that doesn’t fully improve with “healthy eating” alternating constipation or loose stools feeling swollen or distended by the end of the day food sensitivities that seem to come and go or digestive symptoms alongside fatigue and cravings For many women, this leads to the question: is something deeper going on with my gut? Sometimes the answer is sim

If you have PCOS and also experience bladder discomfort, urinary urgency or ongoing pelvic irritation, it can feel confusing trying to understand whether everything is connected or separate. Some women notice symptoms such as: frequent urge to urinate bladder discomfort even when tests are normal pelvic pain or pressure symptoms that flare with stress or hormonal changes discomfort that seems to come and go without a clear pattern When these symptoms sit alongside PCOS, it is

If you’ve been avoiding fat to manage your weight, this could be holding you back Many women with PCOS have been told some version of: “Eat low fat” “Cut calories” “Avoid high-fat foods” So it’s no surprise that fats are often the first thing to go. But here’s what I see in practice, and what research supports: When fat intake is too low (or poor quality), it can actually make symptoms like: Cravings Energy dips Hormonal imbalance Weight struggles harder to manage.
