Gregory Kraut, a managing partner at K Property Group, is paring down—personally and professionally. The 42-year-old has cut out animal products including eggs and dairy; he has stopped drinking and watching TV and he’s added meditation to his daily diet. At work, he and partner Rod Kritsberg are a two-man outfit that has reduced its overhead by working out of a free office, having a CFO on retainer and employing an analyst that is an independent contractor.
