The cookie diet has helped me get in the best shape of my life! They are so easy and convenient, I don’t even feel like I’m on a diet!

This is the best diet, the cookies are absolutely delicious and you never feel hungry. Have lost 3.5kgs in my first two weeks.

I like the Cookie Diet because I crave sweet things all the time! But it’s making me think differently about diets in general, which is great. I did it initially for two months and it really helped. I took off a few kilos I wanted to lose and have maintained the weight off ever since integrating the cookies as snacks with my meals every day. I have to say, the maintenance part of it is my favourite and their cookbook has also really helped me with new recipe ideas.

It’s just so easy to stick to, I just pop it in my hand bag and I’m sorted for the day until my dinner meal. Tastes great, really works, highly recommend!

I put on a weight during lockdown as I let myself go and I’ve been wanting to lose some kg for a while now, but every diet I tried was just not working for me or leaving me so hungry that I would then binge eat to make up for it. My friend Sasha told me about the Cookie Diet and I decided to give it a go. Honestly, this is the best diet I’ve been on so far. I wake up not feeling hungry because I have a good healthy dinner the day before and then I eat my cookies throughout the day and actually feel full!!!!” I’ve lost 5kg in a month so far, it works!

THE SCIENCE OF SATISFACTION
The science behind why you feel fuller for longer.
Each cookie contains special proteins that respond to the stomach’s naturally acidic environment, forming a soft, gel-like structure. This structure is digested gradually, helping support longer-lasting satisfaction between meals.
