Fasted vs Fed Workouts

On this episode of 9 to 5 Wellness, I sat down with Coach Brian to dig into a question I get asked constantly: should you train fasted or fed? We broke down what fasted training actually means — working out on an empty stomach after going roughly 10 to 12 hours without eating — and talked through the real benefits, like the modest fat-loss edge over fed training, better metabolic flexibility, and potential boosts to insulin sensitivity and how your body uses fat for fuel.I shared that I generally recommend fasted sessions for low-to-moderate intensity work — that includes moderate strength training in the 60–75% 1RM range — and I like to keep those sessions under 45 minutes.But we didn't stop there. Coach Brian and I got into where fasted training falls short: if you're doing anything high-intensity — think HIIT, CrossFit, speed repeats — you really need to pre-fuel with simple carbs, and honestly, a 250–300 calorie pre-workout meal is often worth it. For longer sessions, I always tell my clients to get carbs in during the workout too, so you don't hit that wall and bonk halfway through.Post-workout fueling was a big focus for me in this episode. I want people eating within two hours of finishing — or within just 30 minutes if the session was really intense — and pairing carbs with 25 to 50 grams of protein to actually recover well.One thing I made sure to highlight: women should steer clear of truly fasted workouts. Our cortisol tends to run higher in the morning, and that changes the calculation.00:00 Welcome and Topic Setup02:12 Defining Fasted Workouts03:23 Benefits and Fat Loss Evidence05:30 Metabolic Flexibility and Health08:49 Best Intensity for Fasted11:34 When Fasted Fails13:39 Quick Carbs Before HIIT15:48 Breaking the Fast Properly16:52 Fueling Strategy and Timing19:59 NOS Analogy and Intra Fuel23:01 Bonking Lessons From Racing24:59 Fasted Workout Limits25:44 Women And Cortisol26:14 Pre Workout Fuel Ideas28:48 Intra Workout Carbs31:21 Portable Real Food Tips32:25 Post Workout Window36:48 Carbs Insulin Muscle Glycogen38:53 Macros Ratios And Protein40:47 RPE Timing And Recovery45:05 Wrap Up And TakeawaysResearch Studies Related to the TopicExercise Training and Fasting: Current Insights - PMCFasted vs. Fed Workouts: Which One is Right for You?Send us Fan Mail🌟 🌟 🌟 If you liked this episode and would like to learn more about wellness training and workshops offered by 9 to 5 Wellness, email us at [email protected].
