Hi Kevin, I am a yoga teacher and healthy living freak. You can check my blog it has lots of diet hacks to improve health significantly through simple, cheap and small interventions. I am personally mostly vegan (not exclusively) but am aware that lifestyle demands quite a bit of dedication. However just replacing part of animal protein with plant protein can give you a range of benefits. As for exercise I propose three days a week some dynamic yoga routine (Ashtanga yoga is what works the best for me), other two days of some highly efficient high-intensity exercises (15-20 min are sufficient) plus some old school strength building (pushups, pullups, situps) no more than 10 minutes required. Two days a week rest. Also include some breathing exercise (I plan to write more on that subject) every day. My advice to everyone is do not underestimate the importance of flexibility and breath in keeping your body fit and healthy. Also meditation is just about the best thing you can do for your mind.
