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

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 simple cooking that tastes so good too.

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. My skin is glowing like never before too!

Daniella, Marbella

The first 3 days I had a mild headache – i guess that’s part of detox. However, 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! My body really does look very different after the 21 days, especially my stomach!

Richard, Oxford

The diet includes plenty of food that keep us blokes happier! I’ve followed several 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!

Why would you want a consultation

The aim of the 21 day programme is to deliver the best results possible while allowing you to learn along the way. However, if you have a complicated health history, digestive issues or you simply prefer to have some 1:1 input, this is an ideal opportunity to make time for this personalised, professional service.

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

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.

Why can’t I just snack on fruit?

Fruit is undoubtedly a healthy option and is included throughout the G Plan. But rather than graze your way mindlessly through the fruit bowl, we’d rather you only have snacks when you’re truly hungry for one. And we’ve suggested recipes and ideas that, like the meals, provide a balance of carbohydrates and protein so they’ll keep you fuller for longer.

I find it too hard to follow the plan when I’m at work – any tips?

Preparation, preparation, preparation. If you do all your cooking at home and batch cook, you can take things into work to eat. It’s a commitment, but it’s only for 21 days – after that you’re free to relax the rules a little and find other ways to work it. It’s absolutely fine to swap lunches and dinners around if one works better than another as a packed lunch (just make sure you pick meals from the phase you’re on).

If you’re caught out and have to buy something, just try to stick within the guidelines of that phase. Avoid processed foods and sugar. Soups and salads are widely available. And fill your desk and bag with easy snacks like oatcakes, nut butters, miso soup sachets and mini packets of nuts and seeds.

I’ve got a big event coming up with food and drink, can I have a night off?

Ideally, you’ll get through the full 21 days completely on plan. Try to time it that way and clear your calendar of parties that will put you in temptation’s way. That said if you have an unexpected night out, don’t get stressed. Stick to the plan as much as you can, don’t go wild, and get straight back on it the next day. You can even repeat a day if you like.

How does the plan work

It is a 3-phase plan, with a 5 day ‘rest’ phase, 9 day ‘re-wild’ phase and final week of what is ‘re-balance.’

During the initial five-day phase, you’ll be giving your digestive system some well-earned downtime. By temporarily eliminating common gut irritants and keeping the diet simple and easy to digest, you allow any past tummy troubles to settle down. It also gives your weight loss a kick-start, which is always good motivation! As an added bonus, bloating and water retention often reduce too.

This phase is the strictest with smoothies and lightly cooked meals, rather than raw. Meals are based around plant foods, plus protein. Off limits are any processed foods, added sugar, alcohol, gluten, dairy, carbonated beverages (even water) and vegetables from the nightshade family. You’ll be having limited grains (only gluten-free oats and quinoa), caffeine (1-2 cups green tea only) and limited beans and pulses. The foods you eat are all gut soothers, known for their calming, healing effects.

Phase 2 is called Re-wild and it’s when the plan starts to bring the diversity into your diet that your microbiome loves. You’ll carry on with the gut soothers but now add in gut boosters, in the form of prebiotics and probiotics. Expect lots of prebiotic vegetables to give your gut flora the nutrients it needs to thrive and proliferate. And we’re adding in fermented, probiotic foods and drinks like kefir, kombucha, pickles and more, to put more microbes in the gut. During these nine days you have a few more breakfast and snack options. You’re also gradually consuming more beans and pulses and re-introducing eggs.

The final, seven-day phase is called Rebalance. By now you’ll be feeling great and like you’ve really got to grips with this new way of eating. Hopefully you’ve discovered some new tastes and have a good recipe repertoire, too. This phase is about keeping up the good work and re-introducing those food types we cut out in phase one, to see how your digestive systems react. You can now have a small glass of red wine daily, if you like. Day by day we’ll introduce those possible irritants we eliminated in phase 1, so you can easily tell if you react to them.

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.
