The Bottom Line
For 30 consecutive days, I hit 200g of protein per day — roughly 1g per pound of body weight. I tracked the experiment via DEXA scan (pre/post), WHOOP, Oura, and daily food logs.
Bottom line results:
| Metric | Day 0 | Day 30 | Change |
|---|---|---|---|
| Body weight | 215 lbs | 217 lbs | +2 lbs |
| Lean body mass | 175.2 lbs | 178.4 lbs | +3.2 lbs muscle |
| Body fat % | 17.6% | 16.8% | -0.8% |
| Visceral fat | 1.18 lbs | 1.10 lbs | -0.08 lbs |
| HRV (WHOOP avg) | 93.1 ms | 96.4 ms | +3.3 ms |
| Resting HR | 49 bpm | 48 bpm | -1 bpm |
| Recovery score | 61.8% | 65.4% | +3.6 pts |
| Sleep performance | 71.8% | 73.5% | +1.7 pts |
| Strength (3RM deadlift) | 425 lbs | 445 lbs | +20 lbs |
| Strength (3RM bench) | 285 lbs | 295 lbs | +10 lbs |
| Hunger (subjective 1-10) | 6.2 | 4.1 | -2.1 points |
| Energy (subjective 1-10) | 7.4 | 8.3 | +0.9 points |
The most surprising finding: hunger dropped dramatically. I expected to be miserable shoving 200g of protein down every day. Instead, I was less hungry than I'd been in years.
The second most surprising finding: my HRV went up. Protein gets framed as taxing on the kidneys and stressful for the body. My data showed the opposite.
This article walks through the protocol, the foods, the logistics, the lifts, the scans, and the honest assessment of whether it's worth doing.
Why 200g
The "how much protein" debate is fierce.
The conservative camp (RDA): 0.36g per pound of body weight. For me at 215 lbs, that's 77g/day.
The mainstream fitness camp: 0.8-1.0g per pound of body weight. For me, 172-215g/day.
The hardcore bodybuilding camp: 1.2-1.5g per pound. For me, 258-322g/day.
Recent research (Dr. Stuart Phillips, Brad Schoenfeld): Above 0.8g/lb produces diminishing returns for most goals. Past 1.0g/lb, you're optimizing for edge cases.
I picked 200g as a structured, achievable target right at the high end of the mainstream camp. Just under 1g/lb for me. Aggressive but not extreme.
The Daily Food Setup
Here's what 200g of protein actually looks like for me:
Breakfast (50g protein):
- 4 whole eggs (24g) scrambled with spinach
- 1 scoop whey isolate in coffee (25g)
- Black coffee, salt, electrolytes
Lunch (60g protein):
- 8oz grilled chicken breast (52g)
- 1 cup quinoa, mixed vegetables
- Hot sauce, olive oil
Snack (25g protein):
- 1 scoop whey protein in water OR Greek yogurt with berries
- Handful of almonds
Dinner (55g protein):
- 8oz ribeye/sirloin/salmon (50-55g)
- Roasted potatoes/rice
- Salad with olive oil
Pre-bed (15g protein, optional):
- 1 scoop casein protein OR cottage cheese
Total: 195-210g protein. Hit the target every day except 2 (Easter Sunday and a wedding).
Total daily calories: 2,800-3,200 (slight surplus vs my maintenance of ~2,700)
The Hunger Drop Was the Biggest Surprise
I expected to be force-feeding myself. Instead, by week 2, I was less hungry than at baseline.
The hunger drop was so significant I started journaling it explicitly. By day 21:
- I wasn't snacking between meals
- I had no urge for late-night eating
- I had no late-afternoon energy crash
- Coffee + breakfast actually held me until lunch (used to feel hungry by 10am)
The science here is well-established and worth understanding:
Protein produces the strongest satiety response of any macronutrient.
- Triggers cholecystokinin (CCK), GLP-1, and peptide YY — all satiety hormones
- Suppresses ghrelin (hunger hormone) more than carbs or fat
- Slower gastric emptying = more sustained fullness
- Higher thermic effect = more energy spent processing it
The practical implication is bigger than people realize: you're not "trying not to overeat" on high protein. You're just not hungry. The diet self-regulates.
This is why high-protein diets work for weight loss without obsessive calorie counting. You eat protein. You're full. You stop eating. Total calories drop naturally.
The Muscle Gain Math
DEXA scan before and after:
Pre-experiment DEXA (Day 0):
- Total mass: 215.3 lbs
- Lean mass: 175.2 lbs
- Fat mass: 37.9 lbs
- Body fat %: 17.6%
Post-experiment DEXA (Day 31):
- Total mass: 217.0 lbs
- Lean mass: 178.4 lbs
- Fat mass: 36.5 lbs
- Body fat %: 16.8%
Net change:
- +1.7 lbs total weight
- +3.2 lbs lean mass
- -1.4 lbs fat mass
Simultaneous muscle gain and fat loss ("recomp") at age 33 in only 30 days is unusual. The textbooks say you need a calorie surplus to build muscle and a deficit to lose fat. You can't do both at once — unless certain conditions are met.
My conditions:
- High protein (the key variable in this experiment)
- Trained lifter (3+ years of consistent lifting at my level)
- Light caloric surplus (200-400 cal above maintenance)
- Hard training during the experiment (didn't dial back lifting)
This recomp phenomenon is well-documented in trained individuals on high protein with structured training. It's not magic — it's metabolic economics. The body builds muscle from the protein surplus while simultaneously using fat stores for caloric needs not covered by the modest surplus.
The lesson: Adequate protein turns the "bulk or cut" tradeoff into a less binary choice. Trained lifters can simultaneously build muscle and lose fat with the right setup.
The Strength Gains
I tested 3-rep maxes on bench press and deadlift before and after:
Bench press 3RM: 285 → 295 lbs (+10 lbs, +3.5%)
Deadlift 3RM: 425 → 445 lbs (+20 lbs, +4.7%)
These are noticeable gains for someone in their 4th year of consistent lifting. Bench press at 295 for 3 is approximately my second-best ever. Deadlift at 445 is a new PR.
I credit roughly 50% to the protein (better muscle protein synthesis), 30% to the slight caloric surplus, and 20% to the psychological commitment of the experiment driving better training quality.
The HRV Improvement
This was the second-biggest surprise after hunger.
HRV trajectory:
- Days 1-7: Unchanged (baseline)
- Days 8-14: Slight rise (+1-2 ms)
- Days 15-21: Clear rise (+3-4 ms)
- Days 22-30: Stable at +3-4 ms above baseline
The "high protein hurts kidneys/causes inflammation/raises stress" myth is not supported by my data. If anything, the opposite happened.
My current best explanation:
- Protein synthesis during muscle repair is energetically expensive — but the body adapts
- Adequate amino acid supply may reduce overall stress on the system (less catabolism, better recovery)
- The light caloric surplus prevented chronic energy deficit, which raises HRV
- Improved sleep quality (also documented in my data) compounded the HRV benefit
Whatever the mechanism, the empirical result was clear: my HRV went up while eating 200g of protein daily.
The Logistics: How I Hit It Daily
Realistic obstacles I solved:
Problem: 50g at breakfast feels overwhelming
Solution: Whey isolate in coffee. Adds 25g without changing morning food volume. Mix one scoop into hot coffee — tastes like a vanilla latte.
Problem: Lunch protein at work
Solution: Sunday meal prep — 4 lbs of grilled chicken, divided into 5x 8oz portions. Eaten over the week.
Problem: Restaurant constraint
Solution: Default order = double protein, skip the bread basket. Most restaurants will add a second chicken breast or burger patty for $4-5.
Problem: Late evening hunger after big dinner
Solution: This didn't happen. The high protein satiety effect killed late-night cravings.
Problem: Cost
Solution: Costco. Chicken thighs $2.99/lb. Whey isolate $50 for 5 lbs. Total food bill increased about $40/week.
Total weekly food cost: ~$140 for protein-focused diet (vs ~$100 baseline). Roughly $160/month premium for the protocol.
What Didn't Improve
- Cognitive performance: No measurable change in subjective sharpness or focus
- Mood: Stable, no improvement (maybe slight irritability week 1, gone by week 2)
- Skin/appearance: No visible changes I could attribute to protein specifically
- Cardiovascular performance: Running times unchanged
Protein moves muscle, body composition, recovery, and HRV. It doesn't move everything. The brain didn't get sharper. The skin didn't glow. The myth that "you'll feel like a new person on high protein" is overstated.
What the Studies Say About This
The recent research consensus on protein intake:
Schoenfeld & Aragon (2018) meta-analysis: ~0.73g/lb (1.6g/kg) is optimal for muscle gain in trained lifters. Beyond that, diminishing returns.
Helms et al. (2014): 0.7-1.0g/lb is the sweet spot for trained athletes in a deficit (cutting). Less than 0.5g/lb risks muscle loss.
Phillips et al. (2016): Older adults benefit from higher protein (0.6-0.7g/lb minimum) for sarcopenia prevention. The "elderly should eat less protein" advice is outdated.
Recent (2024-2025) research on protein and longevity: Inadequate protein in adults over 40 is more dangerous than excessive protein. Sarcopenia (age-related muscle loss) is one of the strongest predictors of all-cause mortality.
My 200g target was above the muscle-gain optimum but well within safety range for a healthy 33-year-old with normal kidney function.
Is It Worth Doing?
For most people optimizing health and body composition: Yes.
The 30-day high-protein challenge produced:
- Significant body recomposition (muscle up, fat down)
- Notable strength gains
- Improved biometrics (HRV up, recovery up)
- Dramatically lower hunger
- Better daily energy
- No measurable downsides
For $40/week extra in food cost, this is one of the highest-ROI interventions I've tested.
For people with kidney disease or CKD: No. Talk to your doctor. High protein is contraindicated in these conditions.
For people who hate eating large meals: Try the "snack-throughout-the-day" approach. 5 meals of 40g each is easier than 3 meals of 70g each.
For vegans/vegetarians: Achievable but harder. You'll need protein powder, tofu, tempeh, edamame, seitan, lentils, beans. Cost is higher and you have to track more carefully to avoid amino acid gaps.
What I'm Doing Now
After the 30-day experiment ended, I dropped to ~150g/day (still high but more sustainable for me long-term).
Why? 200g/day was achievable but required active focus every day. 150g/day is easier — fewer protein shakes, more variety in meals.
The body composition gains have held. I haven't lost lean mass at the lower intake. The hunger reduction has partially persisted but not completely.
Recommendation for most people: Aim for 0.7-0.9g per pound of body weight as a sustainable target. For someone 180 lbs, that's 125-160g daily. Achievable, effective, sustainable.
200g is a great 30-day experiment. 150g is a better forever protocol.
