Whether it’s your BMI or daily calorie count, health seems to be all about numbers. But the designers behind the Shapa scale are hoping to get people thinking differently about how you measure your fitness, by creating a set of scales that doesn't actually tell you how much you weigh.

While people may once have counted calories to trim their waistlines, many now take a more holistic approach to health. Weight Watchers is repositioning itself as a lifestyle brand with the aid of Oprah Winfrey, who’s using her star power to draw Boomers back to the pioneering weight loss company.

Celebrity endorsements and diet brands have long gone hand-in-hand. Now, amid challenges in the industry, Weight Watchers has received a boost from Oprah, who's bought up shares and has reported shedding 40 pounds through the programme, causing the company's stock to soar.

Popularised by picture-perfect Instagrammers, the clean eating aesthetic isn't accessible to many – and neither are the stores that stock organic goods. But while Whole Foods has gained a reputation as the grocery chain for wealthy health freaks, its latest venture intends to change that.
