10 Days of Veganism: My Vegan Trial

Nutrition Advice


With so many diets and food-related lifestyles being practiced today, I’m often asked for my opinion as a nutritionist. And so I recently decided to give veganism a trial.

Why I did it:

So many JSHealth readers asked me what I think of it. And honesty, from my nutritional knowledge and personal past experiences, I wasn’t the biggest fan. But I felt I needed to try it a bit longer with some adjustments so I could give you a real and honest answer. Our bodies are unique and constantly changing, so something that didn’t work for me in the past might be great now.

How I did it:


I was in Bali for a week visiting various health retreats. Because so much of the Balinese cuisine I experienced was plant-based, I have to admit it was significantly easier. Most of the options were vegan or vegetarian, and most of the food was made for me. I wasn’t in my kitchen cooking like I normally would. I think at home, this would be more challenging. However, these places really inspired me with how delicious and creative plant based, vegan food options can be. I’d love to incorporate these dishes more regularly!


What I was eating:

  • Lots of fruits and vegetables – a huge variety
  • Complex carbs – brown rice, sweet potato, quinoa, oats


  • Beans and legumes – I love lentils
  • Good fats – avocado, coconut, seeds and, in moderation, nuts
  • Tempeh
  • Vegetable and fruit juices and smoothies
  • Lots of water

You may be thinking the options are limited – but I have been surprised by how many options are entirely plant-based! 


How did I feel initially?

  • Definitely hungrier, and hungrier more often. I needed to eat more than usual. I typically eat balanced portion sizes of whole foods (animal protein included) but I definitely needed to eat more fruit, veggies, nuts and seeds to feel satiated.
  • I missed my morning coffee made with whole milk so much!
  • I felt I was detoxifying.

How did I feel after 7 days?

  • I felt more energized and generally in a good mood.
  • My skin and eyes are clearer.
  • My bowel movements are more frequent, perhaps because of all the fiber I’m getting from rice, oats, fruit and veg. I usually “go” once a day, but I have been going 2-3 times a day now.
  • I love eating more fruit than usual – I typically don’t eat much, maybe 2 pieces a day, but I have been starting my day with a big platter of fresh papaya and mango, and I’m loving this.
  • I ate more in general – I just felt I needed to.
  • No more dark circles under my eyes – interesting!
  • My head felt clearer.
  • I woke up starving.


By Day 5, I started to feel more satiated after meals. Before this I was feeling too hungry and not satisfied like I would after eating animal protein.

I was eating more carbs than I normally do and I have really been enjoying nourishing my body with whole grains like brown rice and sweet potato.


I felt more connected to the world I had a deep sense of connection to the universe. I felt more spiritual than usual, and like I was doing something good for the world. I really felt a sense of compassion for animals – something I realized I don’t think about enough.

I was meant to do two weeks, but truth be told –  I didn’t. I was craving protein and my normal diet again by day 10.


What happened to my weight?

Well, I don’t weigh myself so it’s hard to say for sure. I definitely felt lighter and my stomach seemed flatter – I was less bloated. It was, admittedly, a short period of time but there did not appear to be a major impact on my weight.

I will say this, though:

Many of my patients and friends have felt (and I’ve felt this pressure too!) that looking at the “model-like girls” on Instagram or YouTube who advocate a vegan-friendly lifestyle definitely contribute to others wanting to follow this lifestyle.

But this is not a good enough reason to go vegan.

My fear is that too many teenage girls struggling with body image issues would see the very thin girls on social media and immediately want to follow their way of life – without really understanding enough about it all. I worry they may stop listening to the needs of their bodies. This is when young girls run into trouble with their relationship with food. And they risk missing out on the nutrients that support a growing body, too.

Seeing thin girls makes you want to follow what they’re doing, right? We can all fall for this.

I will say again: we are all biochemically unique.

It may be great, but it also may not work for you. Listen to your body. We don’t have to put diet labels on ourselves.

Final thoughts:

I am so inspired by eating plant-based – and yes, I would consider my way of eating now to be “plant-based inspired.”

I think a vegan lifestyle is incredible if it works for you and if you are doing it for ethical reasons – I so respect this.

I would have loved to continue, but I have worked so hard to tune in to my body and listen to its needs. I really do feel animal protein makes me feel more energized, satiated and able to function at my best, and it comes back to what I’ve said before – I think it does not work for everyone.

I was reminded of the importance to respect the uniqueness of our bodies and figure out what works for us. I talk so much more about how I learned to do this in my book The Healthy Life. What works for me is different from what works for you, but doing the work is life-changing.

I encourage you to tune in to your body and tune out from what YouTube, Instagram, magazines and friends are telling you how and what to eat.

Trust your body – it knows best.

Hi Jessica, I believe in synchronicity so when I was guided to you .on FB I was intrigued and inspired. I turned 46 last week and my husband bought me your book. I wanted to thank you for sharing your wisdom in such a beautifully presented way. My  copy is now filled with tabs and post it notes with actual notes throughout. I am dairy intolerant since having my gallbladder removed 15+ years ago, I don't eat meat, very minimal gluten and was told 12 months ago my gut was not digesting my food properly so I wasn't receiving sufficient nutrients and taking supplements would be a waste of time.  My weight fluctuates tending to gain rather than lose but now I believe I have a tool to help me bring my body back into balance that I need for my health and longevity of life - so again thank you. The first few steps to creating a stronger path forward for my health has found its foundation in your beautiful book, The Healthy Life.

With kindest regards Samantha

I'm writing this email because I wanted to tell you how much I love your blog and how you really helped me in my health journey. Thank you for sharing all your advices and experiences.

When I started my studies, I was drinking lots of coffee and I was eaten the wrong foods, and feel bad about it, I wasn't at my best. So I had done some research on the net but at first I didn't found advices that are for me, and then I found your blog. It was exactly what I was looking for, good advices and healthy recipes. Now I'm following your advices on rest more, and snacks between meals and prep the meals and take time for myself to reconnect with my body and let go my anxiety, etc, and I have a more balanced life and have a new relationship with food thanks to you.

I bought your book and it's honestly the best book I have ever bought. I suffer from IBS and anxiety. I have paid so much money seeing naturopaths however after reading your book and all of your tips I'm noticing so much of a difference, so simple and easy to follow. And symptoms have dramatically decreased. Also you have helped me to relax. Currently drinking the protein health smoothie! Thankyou your amazing.


Hey Jessica!
I haven’t yet brought ‘The Healthy Life’, but I do have the clean life and your slim down plan! I would like to thank you so much for the knowledge your share and the message you put across about health and wellness. I’m studying Nutritional Medicine in Melbourne and absolutely love the philosophy that you share with your JSHealth community. The work you’ve done to show people that leading a healthy lifestyle isn’t boring, tasteless, difficult or depriving is amazing and hope to share the message myself one day. You’ve inspired me to start my own blog , to share the message and have taught me so many things about my own health! You should be proud of your achievements! Thank you again

I searched for help and tips through the Internet and found Jessica Sepel. This is seriously not exaggerated, but she was the reason why I have dared myself to eat again, to have snacks in between, to nourish my body. I could slowly improve my negative thoughts about my body image and my stupid anxiety of gaining weight. Besides, The Cleanest Gut was awesome too! A huge thank you! Especially from my mum. Seriously, without you I wouldn’t be where I am now!


Congratulations on your new book! It looks absolutely gorgeous. I’ve been following you on Instagram for a few years and you’ve inspired me to slowly but surely eat healthier without giving myself a hard time when I don’t. It made me so happy (and weirdly proud) to see the Daily Mail article on The Healthy Life. I remember trying out your recipes before you even had your eBook out! I can’t wait to get my hands on the book. Keep up the great work.

Cooking in this way truly brought out the foodie in me and has instilled a huge passion for health and wellness! Life throws you hard and frustrating things sometimes but I truly believe that this is where we learn more about ourselves and what our passions in life are! Thank you for inspiring me on my journey to health and wellness!


I am a yoga teacher in Johannesburg and am thrilled to have bought your book today. I love making healthy, nutritious food for my family, friends and fellow yogis! Thank you for this book and your inspiration (had to share a pic of my book on my recipe stand in the kitchen).

– Helene

I bought your beautiful book during the week and told my bestie to go out and buy it also! I love love love it. It is the book I would give to my younger self if I could (I am 41 years old). Everything is just so sensible and informative and is definitely a book all teenagers should have. This should be a text book for girls becoming teens. I will love going back and re-reading it many many times and can't wait to make more of the recipes. Thank you Jess - you are an incredibly inspiring woman and you should feel so proud
