I've made huge changes in the past two months in regards to my nutrition and have seen massive gains from it. I've lost 15 lbs by eating slow carbs, repeat meals, and fast walks. In order to keep my energy and my mind moving smoothly, I've taken the advice from Tim Ferriss' book Tools of Titans and started mixing my coffee with MCT oil.
Some people call it the Bulletproof Coffee but it's my spin on it with Coconut milk and MCT oil. There is no taste from it, MCT oil is derived from coconuts and it's the healthy type of fat.
This could all be a placebo effect but so far it's helped in losing weight and keeping my mind sharp. Check out the link below for what I've been using.
