Amelia Freer is a London-based nutritionist and former personal assistant to Prince Charles, and she is also the person to thank for soul singer Sam Smith's recent dramatic weight loss. After meeting the health guru, the Grammy-winner lost more than a stone in two weeks, has "completely transformed" his relationship with food and begun sharing snaps of the healthy, gluten and dairy-free meals he now makes.
Based on ten easy steps to a healthier life and looking younger, Amelia's cookbook Eat. Nourish. Glow. is now a bestseller. No doubt due to being in such high demand, the waiting list to hire her holistic health services is currently closed.
Her collection of recipes are both gluten-free and dairy-free and range from sweet delights such as almond, apricot and rose 'yoghurt', healthy salted hazelnut and chocolate caramels to savoury parsnip fritters, as well as chicken nuggets wrapped in lettuce, crab salad, and monkfish with broccoli mash.
Before working with Sam, Amelia had already shown her success on actor James Cordon's diet as well as singer Boy George – who went on to credit her for his four-stone weight loss.
At the time he tweeted some of the secrets of his diet – which is created around the foods that do or don't suit a person: "No coffee or tea, except at meals. Water & fizzy water between meals! No bread, sugar."
As well as offering healthy recipes, Amelia has some tips for an overall change of lifestyle. She recommends easing yourself into her eating plan by giving just one thing up at a time, whether it's dairy, gluten, sugar, alcohol or caffeine – rather than cutting out lots of foods all at once.
She also says "no" to snacking, and encourages a kitchen detox, where all junk food and processed foods are removed from temptation. In their place should go fish, meat, pulses, nuts, seeds, vegetables, dairy alternatives like coconut milk, spices, olive oil, coconut oil, quinoa, brown rice and pasta.
And to complement all the healthy eating? Exercise. Amelia points out that there's "no magic potion, no fairy dust, no one to push you, no one to do it for you," reminding us that the power lies within.
