Good progress, keep your head up, you will get there in no time, concentrate on your goal and look down on the emotional mental part you're going trough now as though you already have passed it and it was nothing of importance to worry about.

One thing I have learned when on keto - you may seem like you are so tired, so exhausted, but its because you dont know your own strength, this first week your body is gonna go trough hell of a roller-coaster, and dont be deceived by your brain telling you feel weak/tired. Lift weights the same way as prior this journey and you will discover that your endurance capacity will be growing beyond your mental capacity, that was my experience. I felt so tired I could actually want to fall asleep while doing my cardio, but as I spend time on the machine I have to re-learn my body and re-teach my mental part of understanding how keto made me feel and what it allowed me to do. In other words I was surprised I outlasted my brain. Brain says fu*k no Im giving up, but muscles were still full of energy, now thats what Im talking about.

Have you heard of MCT oil?
