What to Eat Around Your Workouts

What actually matters, what you can stop obsessing over, and how to build a simple fueling window.

The Hierarchy: Total Intake Comes First

Most discussions of nutrient timing start at the wrong level. Before worrying about whether to eat 60 or 90 minutes before a workout, you need to know whether your total daily protein and calorie intake is adequate. The hierarchy matters because optimizing a lower level when a higher level is broken produces negligible results.

Schoenfeld and Aragon published a widely cited 2013 meta-analysis, "Nutrient Timing Revisited," that established this hierarchy clearly: total daily protein intake is the primary driver of muscle protein synthesis. Meal timing is a secondary variable that produces a meaningful but smaller effect, and primarily in specific contexts: trained athletes, short recovery windows between sessions, or people who train in a fasted state. For a recreational lifter eating adequate protein and calories, the research suggests that fretting over exact meal timing is unlikely to produce measurable gains.

The implication is practical: if your daily protein is consistently 50g below your target, fixing that will produce more results than any peri-workout protocol you layer on top. Get the foundation right first. For the full protein framework, see The Protein Protocol.

Pre-Workout Protein: The Leucine Threshold

The mechanism for pre-workout protein is the same leucine threshold that drives protein distribution across all meals. Leucine is the branched-chain amino acid that directly triggers muscle protein synthesis by activating the mTOR signaling pathway. You need approximately 2.5 to 3g of leucine per feeding to maximally stimulate this process, which corresponds to roughly 30 to 40g of complete protein from most animal sources.

Churchward-Venne et al. (2012) demonstrated that leucine supplementation of a subthreshold protein dose could rescue the muscle protein synthesis response, confirming that leucine is the active threshold signal. Practically, this means 30 to 40g of complete protein before training provides a meaningful pre-exercise anabolic signal that supports muscle protein synthesis during and after the session.

Timing: 1 to 2 Hours Before

The goal is to have amino acids available in circulation when training begins. Digestion takes time, so eating immediately before training is less effective than eating 60 to 120 minutes beforehand. A full meal 90 minutes before a session is the practical target for most people. If you train early in the morning and cannot fit a full meal, even 20 to 25g of fast-digesting protein (like whey) 30 to 45 minutes before can provide a partial signal.

Calculate Your Daily Protein Target

Knowing your pre-workout window helps, but you need to know your total daily target first. Use the Protocol Protein Calculator to find yours based on weight and goal.

Peri-Workout Carbs: Glycogen and High-Rep Work

The case for carbohydrates around training comes from exercise physiology, not marketing. High-rep strength work (8 to 15 rep ranges), HIIT, and anything longer than 45 to 60 minutes of moderate-to-intense effort relies heavily on glycogen, the stored form of carbohydrate in muscle tissue. When glycogen is depleted, exercise intensity drops, fatigue comes earlier, and the training stimulus is compromised.

This is why carbohydrates around training produce a real effect that fat around training does not. Fat is a poor substrate for high-intensity work because it cannot be oxidized fast enough to meet the ATP demand of hard effort. The ISSN position stand on nutrient timing (Kerksick et al., 2017) confirms that carbohydrate availability before and during high-intensity or high-volume training directly impacts performance and the capacity to drive adaptation.

Who Benefits Most from Pre-Workout Carbs

Not everyone needs to eat carbs before every workout. The benefit scales with training intensity and session length.

Practical Peri-Workout Carb Sources

The zone 2 caveat from above is worth linking: for people building their aerobic base, pre-workout carbs are not recommended for steady-state low-intensity sessions. See The Cardio and Zone 2 Protocol for how to structure cardio fueling differently from strength training fueling.

Post-Workout: The Anabolic Window Is Real but Overblown

The concept of the post-workout anabolic window created an entire industry of fast-absorbing protein products timed to the 30-minute post-workout period. The underlying biology is real: muscle protein synthesis is elevated after resistance training, and consuming protein during that window does support recovery and muscle growth. But the window is much wider than 30 minutes, and the urgency has been significantly overstated.

Schoenfeld and Aragon's 2013 analysis found that for most people eating adequate protein across the day, the practical window for capturing the post-workout protein signal extends to approximately two hours post-training. Getting protein within two hours of finishing your session is sufficient. Racing to consume a shake while still in the gym is not necessary unless you trained in a completely fasted state and your last meal was many hours ago.

Post-Workout Carbs for Recovery

Adding carbohydrates to your post-workout meal accelerates glycogen resynthesis, which matters most if you have another session within 8 hours. For people with 24 or more hours between sessions, glycogen replenishment happens passively through normal eating. A post-workout meal with both protein and carbohydrates is good practice regardless: it restores glycogen, reduces muscle breakdown, and supports the insulin response that drives amino acid uptake into muscle tissue.

Training Fasted: What the Research Actually Says

Fasted training is common for people who work out first thing in the morning before eating. The fear around it is usually about muscle loss: training without fuel means the body breaks down muscle for energy. The reality is more nuanced.

For muscle growth outcomes, the research consistently shows that fasted training produces equivalent muscle hypertrophy to fed training when total daily protein intake is matched across both conditions. Schoenfeld and Aragon's analysis found no meaningful difference in muscle gains between fasted and fed lifters who hit their daily protein targets. The mechanism is straightforward: muscle protein synthesis is driven by daily leucine availability and training stimulus, not by whether amino acids were present in your bloodstream at the exact moment you lifted.

Where Fasted Training Does Cause Problems

The practical guidance: if you train fasted, ensure your post-workout meal contains at least 35 to 40g of protein and 40 to 60g of carbohydrates, and eat it within 60 minutes of finishing. Your protein target for the rest of the day remains exactly the same.
