OURA

Magic rings that confer special powers or wisdom have long been part of the fantasy universe. This one uses infrared and LED sensors to measure body metrics and displays personal data about the wearer’s sleep quality, calorie consumption, energy levels or menstrual cycle in the accompanying app. Invented in Finland in 2013, the Oura wellness ring aims to help users improve their sleep and health and understand their body better. It’s a magic business: Last year Oura announced that it had sold over a million rings and had raised new investor capital totaling $2.55 billion. Prices for the ring start at €314, plus €5.99 a month for the app. The limited Gucci version (price: €950) was sold out in next to no time.

“Don’t Lose Your Mind, Lose Your Weight!” is the title of the book the nutritionist published in 2009. It remains the best-selling diet book in India to this day. Rujuta Diwekar has 3.6 million followers on social media. Obesity is increasingly becoming a problem on the subcontinent too, at least in the social classes she works for. Her clients include Bollywood stars and business tycoons. The one-year weight-loss consultation program costs $21,500, with two 30-minute audiences per month. Her approach, which has its roots in ayurvedic teachings, is as simple as it is patriotic: Just eat like your grandparents. Don’t count calories. “Our traditional, collective food wisdom is priceless, but our outlook towards Indigenous foods and customs is skewed because of social media and the influence of big marketing budgets of the food industry,” she says.
