When Tre Munroe walks into Bandra's Kitchen Garden at 3.15 pm, he looks energetic and happy. Considering the blazing October heat and that we are seated in the al fresco area, he already sounds like Superman. That he's returned from an intensive job at JNPT (where he has been since 11 am) adds to this cape. But, wait, there's more. Munroe, 32, hasn't had breakfast or lunch. In fact, aside from black coffee and water, he hasn't ingested anything since the previous night. "My last meal was a cup of chocolate milk at 11.30 pm," he says. Since waking up at 6 am, he has done some yoga stretches (and you only have to see his feed on @chiefwowow to know that it's unlikely that they are lazy stretches), gone to JNPT where as a safety officer he coordinates & facilitates courses on "lift operations" for heavy marine equipment. What he is having with us is his sixth cup of coffee. His next meal is still a few hours away.

Munroe sounds like Superman. But, he isn't the only super in Mumbai. For a city obsessed with eating — dinner dates, lazy luncheons, power breakfasts and Sunday brunches and diets that revolve around what's the next big superfood — there's a fast-growing breed of people that have taken to intermittent fasting. Abbreviated to IF, it's not just the best diet to help you look good, but also feel good, say its practioners. It requires fasting periods of minimum 14 hours per day. It can extend to 24 hours, 36 hours or even five days. Most people on the diet, that mid-day spoke to reported feeling healthy, energetic, lighter and happier.
