Menopause weight gain

I've struggled with understanding by body and weight during menopause. Justine is amazing, kind and knowledgeable. I felt safe to be vulnerable and trusted their insights and structure. I've tried lots of eating plans but with this I've lost a stone and feel full and happy. Healthy eating for life

Best plan I’ve followed …

I’ve now nearly completed a 1 year programme with Justine and it’s been a game changer. I hit my weight loss goals and now feel confident maintaining my results. The plan has been easy to follow, flexible, and actually enjoyable, no strict diets or nonsense. I’ve learnt so much about food and my body. I’m now continuing with her monthly maintenance plan to stay accountable and avoid slipping back in to my old bad habits. I would highly recommend it to anyone wanting real and lasting results ❤️

Best supporting coach

I’ve been with jamjars for around 6 months and it’s changed my life. The support Justine provides is brilliant, she helps you understand what your body needs, explains what weekly targets she wants you to reach and drops in of a weekend to let you know she’s there if you need her.
I’ve thoroughly enjoyed being coached with Justine and I highly recommend anyone to join the JamJar club!

If I could give 10 stars I would ⭐️ I’ve really enjoyed my journey and can’t recommend enough. Suffering from menopausal effects and slowly gaining weight over a few years I’ve not been able to shift on my own but I have now with Justine’s help! Thank you xxx

Fantastic coach highly recommend!!!

Justine has been an amazing coach helping me to achieve my goals and putting together a tailor made plan which really worked. I have struggled to get rid of the last extra pounds… my sweet tooth definitely wasn’t helping. What I have loved about my coaching experience with Justine is not only is she extremely knowledgeable about nutrition she is there to guide you through the whole process and just gets it! Justine has helped me change my mindset towards food, my sugar cravings are no longer out of control and I’ve lost the extra pounds!!

Thank you so much Justine I can’t recommend you enough xxx

The best plan ever!!

I was on the fence for a while but it was the BEST coaching I’ve had, I lost the pounds I’d hoped too without starving myself and through a healthier diet. Justine taught me so much about gut health and introduced me to foods I didn’t really ever think of eating. I’m a much healthier, happier person now and really enjoyed the plan.

I can honestly highly recommend Justine to help you. Thank you xx

🩷 AMAZING!!!

🩷 AMAZING!!!! I signed up for 6 months and am now in maintenance. I no longer dread the Summer outfits and I’ve bought a whole new holiday wardrobe. If I could give more stars 🌟 I would. Great programme, great coaching Justine and all made so simple & good fun. A plan that actually makes sense.
