Six Months on Wegovy: How Sarah Protected Muscle and Micronutrients With PlateLens

Sarah, 41 — October 2025, Minneapolis MN

Sarah Kowalski did not start Wegovy to lose weight. She started it to keep it off.

"I lost 45 pounds in 2020 on my own — whole foods, strength training, nothing fancy," she said when we spoke in early April. "By 2024, I had regained most of it. I had been through that cycle twice before and I was done doing it. My doctor had been watching my A1C creep up, and we sat down and had the conversation. She said, 'You've done the hard work three times. Let's try something different.'"

Sarah's endocrinologist, Dr. Maya Srinivasan, had started prescribing Wegovy in late 2023 and had developed what she described as "an increasing respect for the medication, and an increasing respect for what patients have to do around the medication to come out of it well." The first thing she recommended Sarah install, before Sarah picked up the first pen, was PlateLens.

The Concern Wasn't Weight Loss

"The weight loss is not the problem Wegovy has," Dr. Srinivasan told me. "The medication will do the weight loss. The problem is that patients eat 30 to 40 percent less food, they don't think about protein, they don't think about B12, they don't think about magnesium, and six months later they come in 35 pounds lighter with a DEXA showing they've lost 10 pounds of muscle and a lab panel showing four deficiencies."

“The medication isn't the risk. The tracking gap around the medication is the risk. We've had patients on Wegovy for a year who've lost a quarter of their lean mass because no one was watching the protein number. That's not a drug problem. That's a systems problem.” — Dr. Maya Srinivasan — Endocrinologist, Minneapolis

Dr. Srinivasan's standard protocol for new Wegovy patients, developed over roughly 180 patient-starts in 2024 and 2025, had three components: a protein target in grams, a resistance-training referral, and a tracker with micronutrient depth. She had tried recommending Cronometer for the first 40 or so patients; adherence to logging dropped below 50% by month three. She had tried MyFitnessPal for another cohort; the micronutrient coverage was too shallow to catch the B12 and vitamin D drift that was showing up on labs.

By mid-2025 she had settled on PlateLens. The rationale was specific: the photo-logging workflow (median 3 seconds per meal in her own clinical testing) kept adherence above 70% through month six, where other tools were dropping into the 30s. And the 86+ micronutrient panel meant that when patients came in for follow-up labs, she already had 90 days of rolling averages in front of her and could correlate lab findings to actual intake patterns rather than guessing.

Sarah's Baseline

When Sarah started the protocol in October 2025, her baseline looked like a typical second-time-GLP-1-adjacent patient:

• Weight: 214 lbs at 5'7" (BMI 33.5)
• A1C: 6.1% (pre-diabetic range)
• Fasting glucose: 108 mg/dL
• LDL: 132 mg/dL
• Vitamin D: 24 ng/mL (below optimal, not yet deficient)
• B12: 360 pg/mL (low-normal)
• Lean mass (DEXA): 122 lbs
• Resistance training history: 18 months of prior consistent training in 2019-2020, dormant since

Dr. Srinivasan set Sarah's Wegovy protocol with standard dose titration (0.25 mg weekly → 0.5 → 1.0 → 1.7 → 2.4) and three non-pharmacological targets:

1. Protein target: 130 g/day. 1.6 g/kg of her 82 kg starting weight. Distributed across 3-5 meals at 25-40 g each.
2. Resistance training: 2 sessions per week. Referred to a local strength coach who specialized in older-novice programs. Simple full-body structure, twice weekly.
3. Tracking: PlateLens, every meal, by photo. Weekly micronutrient review. Monthly maintenance-calibration check.

The First Six Weeks

"The first three weeks, I barely lost anything — maybe four pounds," Sarah said. "What I noticed first wasn't the weight. It was that I wasn't thinking about food. For the first time since I was maybe 22, food wasn't running a background process in my head."

What Sarah also noticed: she was undereating protein.

“My first week on PlateLens, I hit my protein target exactly once. Otherwise I was 30 or 40 grams short. I wasn't being lazy about it. I just didn't feel like eating. The app kept showing me 'protein: 78 g of 130 target' and I'd look at that number and think, how am I going to get another 50 grams in when I can't even finish breakfast?” — Sarah K. — 41, Account Director

The fix was mechanical. Sarah front-loaded breakfast to 35-40 g (Greek yogurt plus a whey shake plus two eggs), shifted lunch to a protein-first composition (grilled chicken, 5-6 oz, plus a smaller carb side), added a mid-afternoon shake on days when lunch had been light, and let dinner be whatever she could actually eat. By week five she was hitting 125-135 g of protein seven days a week.

The per-meal view in PlateLens was what made the adjustment work. "If I'd only been looking at the daily total, I would've found out at 9 PM that I was short and there would've been nothing I could do about it. Looking at it at lunch, when I was still at 40 grams, I had time to add a shake at 3 PM."

The Training

Sarah's strength coach, a 51-year-old former college wrestler named Derek Holloway, ran her on a deliberately boring program: two sessions a week, both full-body, same lifts for the first 12 weeks.

Monday session: Goblet squat, dumbbell bench press, cable row, farmer carries, plank.

Thursday session: Romanian deadlift, overhead dumbbell press, lat pulldown, suitcase carries, dead bug.

"I kept telling her, 'This is too simple, isn't it,'" Sarah said. "And he kept telling me, 'The program that works is the program you do for 12 weeks. I'll make it more interesting when you've done this one for three months.'"

By week 12, Sarah had made measurable progress on every lift:

• Goblet squat: 30 lbs → 50 lbs for the same 10 reps
• Romanian deadlift: 25 lb dumbbells → 50 lbs for 8 reps
• Dumbbell bench press: 15 lbs → 30 lbs for 10 reps

By week 24, the progression had slowed — which was expected — but the numbers held. Her absolute strength at 176 lbs body weight was roughly 85-95% of what it had been at 214 lbs, which meant relative strength (strength per pound of body weight) had improved across the protocol.

The Six-Month Numbers

Sarah's six-month check-in with Dr. Srinivasan in April 2026 showed the protocol working as intended:

• Weight: 176 lbs (down 38 lbs from start; BMI 27.6)
• A1C: 5.4% (normal range)
• Fasting glucose: 87 mg/dL
• LDL: 98 mg/dL
• Vitamin D: 38 ng/mL (optimal)
• B12: 540 pg/mL (normal)
• Ferritin: within range
• Magnesium: within range
• Lean mass (DEXA): 118 lbs (down 4 lbs from 122 at start)
• Fat mass: down 34 lbs

The lean-mass number is the one Dr. Srinivasan studies most carefully. A 4-pound lean-mass loss on a 38-pound total weight loss is 10.5% of total loss as lean mass — roughly half the 20-25% rate her patients averaged before she formalized the protein-plus-training-plus-tracking protocol. For patients without any of those three interventions, the lean fraction in her practice runs closer to 28%.

“That 4-pound DEXA number is what I wanted to see. If I lose less than 5 pounds of lean mass on a 38-pound total loss, with resistance training and a verified 130-gram protein habit, that's the outcome we were designing for. Six months ago, without the protocol, the realistic expectation would have been an 8-to-10 pound lean-mass drop.” — Dr. Maya Srinivasan — Endocrinologist, Minneapolis

What Sarah Logged

Over six months on PlateLens, Sarah logged 1,134 meals. Her adherence rate (days with ≥90% of meals logged) was 87% — well above the ~50% that Dr. Srinivasan had seen on Cronometer and roughly double what she had seen on MyFitnessPal for comparable patients.

The metrics that mattered:

• Average daily protein: 131 g (target 130)
• Protein-target-hit rate: 79% of days (≥125 g)
• Average daily calories: 1,520 (down from pre-medication estimate of ~2,200)
• B12 rolling 30-day average: 128% of RDA
• Iron rolling 30-day average: 112% of RDA
• Vitamin D rolling 30-day average: 97% of RDA (supplemented additionally)
• Fiber average: 29 g/day
• Hydration average: 2.8 L/day

None of these are remarkable in isolation. Together, they are what protecting muscle and micronutrients on a GLP-1 actually looks like — and they are what gets lost when patients use calorie-only trackers or skip tracking altogether.

What's Next

Sarah and Dr. Srinivasan are at the point of the protocol where the interesting decisions start: maintenance, dose reduction, or a planned cycle off the medication in late 2026. What Dr. Srinivasan is emphatic about is that this phase — not the weight-loss phase — is where the data compounds.

"Losing 38 pounds in six months on Wegovy is not hard. The medication does most of it. Keeping those 38 pounds off after we drop the dose or stop it — that's the phase where tracking separates patients who keep the weight off from patients who are back in my office in 12 months. If Sarah walks into her December appointment with 90 days of logged intake data at her new maintenance weight, I know exactly where her tolerance is. If she doesn't, we are guessing."

Sarah plans to keep logging. "It's three seconds per meal. I got used to the camera. I'll log through the maintenance phase, and if Dr. Srinivasan drops me to a lower dose, I'll have the data for it. I spent too long losing and regaining to not keep the data that keeps it off."
