Dr. Stacy Sims argues that women should not automatically copy the black-coffee-and-fasted-workout pattern that may appear to work for men. Her decision rule starts with the session: before strength work, she suggests about 15 grams of protein; before cardio or mixed cardio and strength, she suggests adding roughly 30 grams of carbohydrate. After exercise, she recommends a protein-rich recovery serving within about 45 minutes and cites 35 grams for women in their reproductive years. These quantities are Sims's episode recommendations, not universal prescriptions. The reusable mechanism is to identify the work, provide enough incoming fuel to support it, recover promptly, and then monitor performance, digestion, appetite, and recovery so the approach can be individualized.

Core principles
- 01Fuel the work rather than defaulting to fasted training
- 02Match pre-workout carbohydrate to the session demand
- 03Use protein around strength work
- 04Prioritize the shorter post-exercise recovery window Sims describes for women
- 05Adjust for individual tolerance and medical needs
How to run it
- 1
Classify the workout
Decide whether the upcoming session is primarily strength, cardio, or a demanding mixture of both.
Pro tip Base the choice on the actual work planned, not the label of the class.
- 2
Select pre-workout fuel
Following Sims's episode guidance, use about 15 grams of protein for strength work and add about 30 grams of carbohydrate for cardio or demanding mixed work.
Pro tip Choose a small, familiar option that is easy for you to digest.
Watch out These are general recommendations from the guest, not a personalized prescription.
- 3
Train with purpose
Complete the planned workout and observe whether the pre-workout feed supports energy and performance without digestive discomfort.
Pro tip Keep other variables reasonably consistent while testing the approach.
Watch out Stop and seek appropriate help for concerning symptoms.
- 4
Recover promptly
Have a protein-rich recovery serving within roughly 45 minutes. Sims cites 35 grams for women in their reproductive years.
Pro tip Plan the recovery option before training so convenience does not decide for you.
Watch out Protein needs differ with body size, total diet, health, and training load.
- 5
Review the response
Track energy, performance, appetite, digestion, and recovery, then adjust food choice or timing while preserving the fuel-before-and-recover-after structure.
Pro tip Judge the pattern over several comparable sessions rather than one workout.
In the wild
A healthy adult woman who usually trains after only coffee plans a mixed strength-and-cardio session. She tests a small familiar meal containing protein and carbohydrate beforehand, then has a protein-rich breakfast soon after finishing. She records energy, stomach comfort, and recovery across several similar sessions.
→ She evaluates Sims's fueled-training approach against her own response instead of assuming fasted training is optimal.
Common mistakes
Copying a partner's fasting routine
The episode's central claim is that the same routine may not produce the same response in women and men.
Turning example doses into absolutes
Sims gives practical quantities, but individual needs and tolerances vary.
Delaying recovery by default
Sims describes a shorter post-exercise opportunity for women and recommends prioritizing prompt protein intake.
Is it for you?
Best for
It is best for healthy adult women planning strength, cardio, or mixed training who tolerate food before exercise.
Not ideal for
It is not individualized nutrition advice for pregnancy, diabetes, eating disorders, gastrointestinal conditions, or clinical weight management.
From the transcript
“It only takes a little bit of food to then have benefit for what you're doing.”
“The window of opportunity for women post exercise is around that 45 minute mark.”
