Two Sessions a Day and a 2,400-Calorie Recall
Jonah is a 22-year-old back-row forward, 95 kg and 185 cm, training twice a day five days a week. He wants to add 3 kg of lean mass in eight weeks. A 24-hour recall shows no breakfast, roughly 2,400 kcal, about 90 g of protein, and about 250 g of carbohydrate. He sweats approximately 1.6 L per hour and drinks 400 mL of plain water during a 90-minute session; he reports calf cramps in the final 20 minutes. He takes a pre-workout with 350 mg of caffeine before his evening session and asks whether he should add creatine and beta-alanine.
1. Prioritize the changes. Calculate his protein target and explain why energy intake, not supplement choice, is the first lever.

Step 1 - establish the scale of the problem with rough arithmetic. Resting metabolic rate by Mifflin–St Jeor: (10 × 95) + (6.25 × 185) − (5 × 22) + 5 ≈ 2,000 kcal. With twice-daily training, an activity factor around 1.8–2.0 puts maintenance near 3,600–4,000 kcal/day. He is eating 2,400. That is a deficit of well over 1,000 kcal in an athlete whose stated goal is a surplus. No supplement fixes that.
Step 2 - protein. Target 1.6–2.0 g/kg for a strength/power athlete in a gaining phase: 152–190 g/day. He is at 90 g - roughly half. Distribute across 4–5 feedings of ~35–45 g, including one within a couple of hours of training.
Step 3 - carbohydrate. With two sessions a day, 6–10 g/kg applies: 570–950 g/day. At 250 g he is not just under-fuelled for growth, he is under-fuelled for the sessions themselves - which will degrade session quality, and low carbohydrate availability blunts the very training stimulus that drives hypertrophy.
Step 4 - sequencing.
- Add breakfast (a 500–700 kcal meal with 40 g protein) - the single highest-yield change, since he currently eats nothing before his first session.
- Build out carbohydrate around both sessions.
- Hit the protein floor consistently before optimizing anything else.
- Only then discuss supplements.
Honest framing of the goal: 3 kg in 8 weeks is ~0.375 kg/week. Achievable in a young athlete in a surplus, but a portion will be fat and glycogen-bound water, and he should know that up front. Also: creatine will add 1–2 kg of intracellular water in the first weeks. If he is weighing himself daily against a "lean mass" target, that water will be misread - decide now that the scale is a trend tool, not a scoreboard.
2. Address the cramping and the hydration strategy with the numbers given. What is missing from his current fluid plan?

The arithmetic
- Sweat loss: 1.6 L/h × 1.5 h = 2.4 L per session.
- Intake: 400 mL of plain water.
- Net deficit: ~2.0 L per session, twice a day, five days a week. That is a chronic, compounding deficit, not an acute one.
Replacement
- Post-session, aim for roughly 125–150% of what was lost: about 2.5–3.0 L over the hours after, sipped rather than chugged, since rapid large boluses drive urine output.
- During the session, drinking to thirst is a reasonable default, but at 1.6 L/h he should be closer to 500–800 mL/h than 400 mL total.
What is missing
- Sodium. Plain water in a heavy sweater dilutes plasma sodium further. He needs an electrolyte source - a sodium-containing beverage or food - not water alone. Sweat sodium varies widely between individuals; a practical test is whether his kit shows white salt stains, and if so, err toward the higher end.
- A pre-session baseline. He skips breakfast. Arriving at a session already down 1 L from overnight losses plus no fluid means the cramp in the last 20 minutes is entirely predictable - it is arriving at the end of a session that started behind.
- A same-day, two-session plan. Two sessions means rehydration between them is as important as during them.
Interpretation caution: cramping is multifactorial - neuromuscular fatigue and a novel high-load session are plausible contributors alongside sodium and fluid balance. Do not promise that salt fixes it. Fix the obvious deficit, then reassess. And monitor body mass before and after a session to individualize the sweat rate rather than trusting the group estimate.
3. He asks specifically about creatine, beta-alanine, and his pre-workout. Give a decision and a rationale for each, including anything you would remove or change.

Creatine monohydrate - yes. 3–5 g/day, every day, timing irrelevant. No loading phase is required; loading (about 20 g/day split over 5–7 days) only reaches saturation faster. It is the best-evidenced ergogenic supplement for repeated high-intensity efforts, which is exactly a back row's job. Expect 1–2 kg of water-weight gain in the first weeks - warn him, or he will panic about the scale. Buy a third-party-tested product, since supplements are not pre-market verified for purity.
Beta-alanine - reasonable, with caveats. 4–6 g/day in divided doses (to limit the harmless paraesthesia/tingling). It buffers intramuscular acidity and has evidence for efforts lasting roughly 60–240 seconds - repeated scrums, repeated high-intensity bouts. It is not useful for single maximal efforts or long steady work. So: useful for him, but it is a second-order lever behind calories and protein. The tingling is not a sign of efficacy and not a sign of danger.
Caffeine - keep it, move it. 3–6 mg/kg puts his range at 285–570 mg; 350 mg sits inside that. The problem is not the dose, it is the timing: taken before an evening session, it will still be meaningfully active at bedtime, and he is already fighting a recovery deficit. Sleep is the highest-value recovery tool he has. Action: shift the caffeine to the morning session, reduce the evening dose, and if he needs an evening boost, use a lower dose earlier in the afternoon. Do not add caffeine on top of a 350 mg pre-workout.
What to remove or question
- Any stimulant 'blend' he cannot quantify - he should know his total daily caffeine, not just the pre-workout figure.
- Nothing here replaces the 1,200-kcal gap. State plainly: the supplement stack is worth a few percent; breakfast and a protein target are worth the entire goal.
