If you have PCOS and feel like you’re doing everything right but the scale won’t move — you are not lazy, broken, or lacking discipline. PCOS weight loss is harder, and there’s real science behind why. For years, I struggled to lose weight with PCOS despite dieting, exercising, and “doing what worked for everyone else.” What finally changed wasn’t working harder — it was working smarter and with my hormones, not against them. In this post, I’m breaking down why PCOS weight loss feels so difficult and what actually helped me lose weight sustainably.

Why Weight Loss Is So Difficult With PCOS
1. Insulin Resistance Is the Biggest Barrier
One of the most common PCOS symptoms is insulin resistance, which means your body doesn’t respond well to insulin. As such, when insulin levels stay high:
- Fat storage increases
- Fat burning decreases
- Hunger and cravings skyrocket
This is why many women with PCOS gain weight easily and struggle to lose it, even in a calorie deficit.
2. Hormonal Imbalances Work Against You
PCOS impacts hormones like insulin, testosterone, cortisol, and estrogen. These imbalances can:
- Slow metabolism
- Increase abdominal fat
- Make traditional cardio-heavy workouts less effective
Weight loss with PCOS isn’t just calories in vs. calories out — it’s hormone regulation first.
3. Chronic Inflammation Makes Fat Loss Slower
PCOS is associated with chronic low-grade inflammation, which interferes with fat loss and muscle building recovery. This is why lifestyle, supplementation, and recovery matter just as much as diet and exercise.
What Helped Me Lose Weight With PCOS
1. Ovasitol for Insulin Support
One of the most impactful supplements I added was Ovasitol, a combination of myo-inositol and D-chiro-inositol. I personally chose Ovasitol because it’s one of the most researched inositol supplements for PCOS.
Why it helps:
Improves insulin sensitivity, supports ovulation and hormone balance and reduces cravings. This was foundational for me because without addressing insulin resistance, nothing else worked long-term.
2. Berberine Supplements (Why I Prefer Dihydroberberine)
Berberine is widely used to support blood sugar regulation and insulin sensitivity, which is especially important for women with PCOS. However, traditional berberine isn’t always well absorbed by the body. That’s why I personally choose dihydroberberine. Dihydroberberine is a more bioavailable form of berberine, meaning the body absorbs and utilizes it more efficiently. Because of this improved absorption, many people find they need a lower dose compared to regular berberine, which can also make it gentler on digestion. For me, using dihydroberberine helped:
- Support more stable blood sugar levels
- Reduce insulin spikes
- Minimize digestive discomfort
If you’re using berberine for PCOS and insulin resistance, choosing a more absorbable fAndiorm can make a noticeable difference. Also, it’s good to mention that berberine/dihydroberberine works similarly to metformin for some women but without the harsh side effects (always check with your doctor).
3. Weight Lifting 3x a Week to Build Muscle
Instead of excessive cardio, I focused on weight lifting for 1 hour, 3 times per week.
Why strength training works for PCOS:
- Muscle improves insulin sensitivity Raises resting metabolic rate Helps burn fat even at rest
- Building muscle made my body more metabolically flexible — and weight loss finally became possible.
4. Strategic Fasting (Without Starving My Body)
I use a combination of:
- 16:8 intermittent fasting daily
- One 36-hour fast per week
But here’s the key: I do NOT under-eat. If my daily calories are 1,500, I focus on weekly intake instead:
1,500 calories x 7 days = 10,500 calories per week
I distribute those calories in a way that works with fasting without depriving my body of nutrients. This approach supports insulin sensitivity while preventing metabolic slowdown.
5. Staying Hydrated During Fasting
Hydration is critical, especially when fasting. I use Liquid IV to maintain electrolytes and avoid dizziness or fatigue. I also drink plenty of water and listen to my body rather than forcing a specific number of ounces. A simple check I use? Urine color — pale yellow means I’m hydrated.
6. Low-Carb, High-Protein, Moderate-Fat Nutrition
My nutrition style is:
- Low carb (to manage insulin)
- High protein (for muscle and satiety)
- Moderate fat (for hormone health)
This way of eating keeps my blood sugar stable and helps reduce inflammation.
7. Daily Movement (Without Overtraining)
Every single day, I move my body for at least 30 minutes, either by:
- Walking
- Riding my Peloton bike
This keeps stress hormones lower while still supporting fat loss.
8. Addressing Vitamin & Mineral Deficiencies
I worked with my doctor to check for deficiencies — something many women with PCOS overlook.
Common PCOS deficiencies include:
- Iron
- Vitamin D3
- Magnesium
Correcting deficiencies improved my energy, recovery, and overall progress.
9. Marine Collagen (For Skin Elasticity)
As I lost weight, I wanted to be intentional about supporting my skin — especially elasticity — so I added Marine Collagen to my routine instead of other types of collagen. Marine collagen is sourced from fish and is naturally rich in Type I collagen, which is the primary collagen found in skin. Because of its smaller peptide size, marine collagen is often considered more easily absorbed by the body compared to some bovine or multi-source collagens. I personally prefer marine collagen because:
- It specifically supports skin elasticity and firmness
- It’s often more bioavailable, meaning the body can use it more efficiently
- It supports hair, skin, and nails, which can be impacted during weight loss
- It feels lighter and easier to digest for me
During PCOS weight loss, where fat loss can happen unevenly, supporting skin health helped me feel more confident and supported in my body.
10. Creatine (For Muscle Recovery)
When I committed to strength training as part of my PCOS weight loss journey, I also focused on recovery — because recovery is just as important as the workout itself. That’s why I added Creatine to my routine. Creatine is one of the most researched supplements for muscle strength, recovery, and performance. For women with PCOS, building and maintaining muscle is especially important because muscle helps improve insulin sensitivity and supports a healthier metabolism. I use creatine because it helps:
- Improve muscle recovery after weight lifting
- Support strength and performance during workouts
- Preserve lean muscle while losing fat
- Support metabolic health through increased muscle mass
There’s a common misconception that creatine causes bulky muscles or unwanted weight gain in women. In reality, creatine supports muscle function and recovery, not fat gain — and any initial water retention is typically temporary and intracellular (within the muscle), not fat. For me, creatine made it easier to stay consistent with weight lifting and recover well between sessions, which ultimately supported my fat loss goals.
Final Thoughts: PCOS Weight Loss Requires a Different Approach
PCOS weight loss is not about punishment, restriction, or endless cardio. It’s about supporting insulin sensitivity, building muscle, nourishing your body properly and managing stress and recovery. Once I stopped fighting my body and started supporting it, everything changed. If you’re struggling with PCOS weight loss, know this: your body is not the problem — the approach is.
