I do all my distance running first thing in the morning, empty stomach aside from some black coffee. I’ve found I get the best results that way – in terms of how I feel on my run, as well as the physical appearance results.
I lift fasted usually once per week (Fridays), since that’s just accessory work. I have found that I perform better for my main lifts when I have food in me, so I lift in the late afternoon most of the time…just personal preference based on my experiences and how my own body responds. Leg day fasted is a hard “no”.
@Eke I’m not a physiologist or nutritionist, but I don’ t think training fasted triggers a starvation response. It’s a common practice. What does do that is if one were to go from eating, say, 2,500 calories a day, and then suddenly make a huge drop to sub-1,000 calories, something like that. Your body is going to cling to fat cells for dear life, and store any excess when possible. Another example is if you suddenly drop your carb intake drastically, like 300g per day to less than 100g carb per day, overnight.
The examples above can be avoided by doing gradual decreases, avoiding drastic + fast changes to calories and/or macros. But training fasted and then eating after causing the body to enter starvation mode? I have never heard that before.
