"I also walk somewhere peaceful for an hour at least 3 times a week, (never in the hot sun which totally drains me) often more, depending on my energy.I definitely put on weight when I visit the UK as I am mostly unable to find a space to practice yoga and everyone I visit eats quite unhealthily, in my opinion (loads of instant cook, high sugar and starchy foods), maybe he is because it is so cold" . . . .
