Success stories

We’ve been busy working with some early-bird clients on the diet and here’s what they have to say

Lucy, London

“7lbs lost over 21 days and I can honestly say I never felt hungry on this diet. I don’t think there are many healthy eating plans you can say that about! The food was filling, affordable, easy to prepare and it was very refreshing to go back to basics and cook everything from scratch.”

Sharmayne, Gullane

I’m already pretty fit and healthy but wanted to focus on that last 10%. This programme has been hugely beneficial and I’m LOVING the recipes. It is more of a lifestyle change than just a diet for 21 days and what I’ve learned is proving invaluable.

Daniella, Marbella

I lost 2.5kg even though I cheated during the 21 days! The first 3 days my energy was lower and I had a mild headache, which disappeared on the 5th day. I didn’t feel hungry with the diet which was great and my skin got very bright. I even lost my cravings for sugar, which is incredible!

Richard, Oxford

The diet includes plenty of food that keep us blokes happier! I’ve followed several of Amanda’s other diets but find them harder to stick to than this one. There’s plenty of food to keep us blokes happier and I still managed to get the result – I’m not saying how much I lost but my wife seems pleased!

    frequently asked questions

    answers to some of our frequently asked questions – if not here contact us on live chat!

    What can you eat on the diet?

    Variety is the name of the game! The more diverse the healthy foods in the diet the better really. So, although foods such as vegetables are a key part of the plan, there’s tonnes of ideas for how to make them tastier and more interesting than ever.

    There’s no cutting out of any major food groups either so it is less restrictive than many diets. The recipes contain a balance of carbohydrates, proteins and essential fats but just as importantly, they are very tasty and filling too. The menu is also designed to flex around vegetarians and vegans.

    Weight loss on the G-Plan

    How much weight can you expect to lose?

    Those on the trial lost between 8-10lbs on average over the 21 day plan. As ever, the more weight someone has to lose, generally the faster it comes off. So, if you have just a couple of pounds to lose, chances are you’ll lose a little less.

    Will I put all the weight back on once the 21 days are up?

    If you revert to bad eating habits then of course, you will regain weight over time. But the G Plan is designed to teach you a better way of eating for life. Once you’ve taken the time to give your digestion a rest, eliminate junk, build up your gut health and increase the range of foods you eat, we don’t think you’ll want to return to your former ways. Think of these 21 days as your kickstart, then the rest is easy.

    Why is gut health important?

    The trillions of microbes in your gut are not only essential to how you digest food, they also provide vital enzymes and vitamins and control the calories you absorb, linking the health of the gut directly to weight issues. Whether you want to lose weight or not, whether you’re one of the one in four people who struggles with a digestive issue, you can benefit. The evidence is there. Good gut health has an impact on your digestion, your day-to-day comfort and energy levels, your immunity, mental wellbeing and your chronic disease risk.

    So, what can you do now to start benefitting? The answer is – everything! You are in charge of your gut health. What you eat and how you support your microbiome determines your personal pick ’n’ mix of gut bacteria that are then able to help keep you happy, healthy and naturally slim. Which is exactly what the G Plan Programme is designed to do!

    What’s your nutrition expertise in gut health?

    I’ll be honest, I wasn’t always so enamored with the idea of gut health. I took the well-trodden path of irritable bowel syndrome (IBS) and poor skin in my teens. The antibiotics to improve the skin worsened the tummy troubles. My calorie-controlled diet – a rite of passage at that time – was a disaster for my gut and fed carb cravings. It wasn’t until I began to study nutrition that a change of diet solved the triple whammy of woes and changed my life, body and career forever. Fifteen years later I understand and appreciate that my personal experience and professional career in my nutrition clinic and on specialist retreats throughout the world has helped carve out what has now become the G-Plan’s approach of Rest, Re-wild and Rebalance. So, I am certainly not the only nutritionist that can help gut issues but I have almost fifteen years of experience and endless enthusiasm for digesting the latest information and findings, all of which I will use to continually update this online programme. That’s the beauty of working in this way – I can update your online course at short notice and present the new information through webinars and forums. Amanda

    I need to gain weight, can I still do the G-Plan?

    Many people with gut issues or digestive disorders are either underweight or don’t wish to lose weight. With that in mind, you are guided throughout the menu plan towards our higher calorie, high nutrient ingredients and menu options, all of which still remain gentle and nourishing on the digestion.

    What is FODMAP friendly?

    The G Plan focuses on the balance of the microbiome, with all the resulting health benefits. However, for people with Irritable Bowel Syndrome (IBS) and symptoms of an irritable bowel, we have introduced Low FODMAPs throughout. A low FODMAPs diet has been proven, with solid scientific research, to reduce symptoms of fatigue, lethargy and poor concentration, and symptoms of an irritable bowel. Such symptoms include excessive wind / gas, abdominal pain, bloating and distension, nausea and changes in bowel habits (diarrhoea and/or constipation).

    What are FODMAPs?

    The acronym FODMAP stands for Fermentable Oligosaccharides, Disaccharides, Monosaccharides And Polyols. These short-chain carbohydrates are incompletely absorbed in the gastrointestinal tract and can be easily fermented by gut bacteria. These sugars also exert an osmotic effect, increasing fluid movement into the large bowel. The fermentation and osmosis caused by these undigested sugars are a cause of major IBS symptoms such as gas, pain, and diarrhea.

    There are many common foods that are high in FODMAPs that can potentially contribute to IBS symptoms, even if they are considered healthy by most standards. Lactose from dairy products, fructose from certain fruit, coconut products, and sweeteners, fructans from fibrous vegetables, and polyols from fruit and sugar alcohols are all rich in FODMAPs and can be difficult to digest for people with functional gut disorders. These foods can cause painful symptoms in those with IBS and Crohn’s disease. We have ensured that the G-Plan has a FODMAP friendly menu option for each and every meal and our digestive coaching helps sufferers of digestive complaints educate themselves towards long-lasting health improvements.

    You seem to use a lot of olive oil, coconut oil and milk and even butter – what happened to low fat?

    This diet isn’t about high or low cal or high or low fat or carb… it’s a high diversity diet. Olive oil is good for you, coconut oil and milk have metabolism-boosting benefits and butter also has links to health gut compounds. So yes, the G Plan uses healthy fats, in moderation.

    And nuts and seeds, how do they fit in?

    More of those healthy fats, and a source of protein, vitamins and minerals and antioxidants. They also provide prebiotic fibre to feed your gut bacteria. Yes you need to keep portion sizes in check, but they’re so very good for you, you can enjoy more than you think – especially when you’ve cut out all the junk from your diet.
