Impressed by the "energy and vigour" of Prime Minister Narendra Modi during his recent visit to the US despite being on fast, President Barack Obama has expressed his interest in yoga, officials have said.            

While the First Lady has been instrumental in introducing yoga inside the White House, Obama appeared to be very impressed by the energy and vigour shown by Modi when he hosted the latter over a private working dinner in the Blue Room of the White House on Monday.            

"They joked about the fact that the rest were eating and the prime minister (Modi) was fasting. The President expressed admiration for the energy and the vigour with which the PM was able to maintain this rigorous schedule on a diet of only warm water," Assistant Secretary of State for South and Central Asia, Nisha Desai Biswal told reporters.
