When I was a wrestler in high school, I could cut weight pretty easily. Not that it was easy, but I could do it. I kept my 6-pack through my 20’s without any trouble and I ate what I wanted. But skip ahead a few decades and let me tell you, it ain’t easy. I could fast an entire day and still gain a pound. For aging men, testosterone isn’t there at the levels that it used to be. And I empathize with many women post-pregnancy. Its a battle for sure.
I listened to a Barbell Shrugged podcast this morning. I haven’t even listened to the whole thing and I’m super stoked! They talked all about metabolism, insulin sensitivity, and other sciency things. They mentioned a study with women athletes where they found doing cardiovascular (aerobic) work following a heavy lifting session showed no positive effects. The podcast guest (sorry need to look up his name again) suggested we should split aerobic and heavy lifting sessions apart. This is true even for CrossFit athletes who tend to want it all in one fell swoop.
The reason is due to our use of energy systems. If we are using an ATP/CTP rich system that lasts only 10 seconds, we need to focus on carbohydrates to fuel the work. If we are doing low-intensity endurance work, we should focus more on a long-lasting, fat-burning system. In CrossFit, we do mix the systems, but it works differently from how you would think. Yes, the glycogen pathway is used for the heavy lifting part, but when you rest or lower intensity, this is when the fat-burning system takes over. But our bodies don’t adapt well to mixing the two together.
So then we come back to fat. I realize I’ve been doing it wrong. I eat BIG usually later in the evening thus abiding by my Warrior Diet (mostly Paleo) concepts. Then I do intermittent fasting most of my workday. However, this often fails because I run out of energy doing heavy lifts or CrossFit WODs in the morning or I start to get so hungry that I feel I need to eat lunch. So I probably undermine the benefits of fat-burning through intermittent fasting. To tell you the truth, as I get older, its harder to move faster and lift heavier earlier anyway. I’m much more mobile later in the day. So here is my new plan:
- Dinner at night – protein- and fat-rich to encourage recovery, growth, and sleep
- Sleep – monitored by my Sleep App for quality
- Wake – walk dogs, coffee, & news; cardio (run, bike, ski erg, rowing)/yoga
- Work Day – intermittent fasting, maybe having some coconut oil or peanut butter
- Late afternoon – Carb/Protein shake, maybe rice, 1+ hours before workout
- Heavy Workout – Powerlifting; CrossFit WOD; Olympic weightlifting (no cardio)
I look forward to seeing how this works for me. I think it will solve my fat-burning issues and will encourage more strength and growth.
