Mike's Body Recomposition: How He Lost Fat and Gained Muscle in 6 Months
Mike, 28, software developer, achieved body recomposition — losing fat and gaining muscle simultaneously — through precise macro tracking with PlateLens.
Body recomposition — losing fat and gaining muscle simultaneously — is the most technically demanding goal in fitness. It requires operating in a very narrow metabolic window: a deficit large enough to mobilize fat stores, but not so large that the body catabolizes muscle tissue. The margins are razor-thin, and the margin for error in calorie and macro tracking is essentially zero.
Mike Torres understood this intellectually. He had been lifting weights seriously for three years and had read enough exercise physiology to know that recomposition demands precision. What he did not have was a tracking tool capable of delivering it.
"I had been using a notepad app to estimate calories," the 28-year-old Seattle software developer told me in September 2024. "I knew roughly what I was eating, but roughly is not enough for a recomp. You need to know within 50 or 100 calories, not within 300."
The Starting Point
In March 2024, Mike had a DEXA scan at a local sports medicine clinic. The results: 195.4 lbs body weight, 22.1% body fat. That put his lean mass at approximately 152 lbs and his fat mass at roughly 43 lbs. His goal was to reach 15% body fat while preserving — ideally, increasing — his lean mass.
At 5'10" and 195 lbs with 4 days per week of heavy strength training, his TDEE came out to approximately 2,700 calories. He set a target of 2,400 calories — a 300-calorie daily deficit, which represents roughly 4% below maintenance. Conservative enough to preserve muscle. Consistent enough to produce fat loss over time.
“On a recomp the margins are tiny. Plus or minus 1.2% accuracy matters. If I'm off by 200 calories a day over six months, I've either not lost the fat I wanted or I've lost the muscle I need.” — Mike T., 28
Why Macro Precision Matters in a Recomp
For a body recomposition protocol, total calories are only part of the equation. Protein distribution is critical: research consistently shows that consuming 0.7 to 1.0 grams of protein per pound of body weight, spread across multiple meals, maximizes muscle protein synthesis while in a deficit.
Mike's target: 190 grams of protein per day, divided as evenly as possible across four meals. "If you're logging protein manually, you're going to be off," he explained. "A chicken breast looks like it could be 30g protein or 50g protein depending on the size. PlateLens sees the portion and gives you the actual number."
Mike's Macro Targets vs. Average Actuals — by Phase
| Calories | Protein | Carbs | Fat | |
|---|---|---|---|---|
| Target (all phases) Daily goal | 2400 kcal | 190g | 220g | 72g |
| Phase 1 (wks 1–8) Avg. logged | 2387 kcal | 184g | 218g | 71g |
| Phase 2 (wks 9–16) Avg. logged | 2412 kcal | 192g | 222g | 73g |
| Phase 3 (wks 17–24) Avg. logged | 2401 kcal | 196g | 219g | 72g |
The consistency is striking. Over six months, Mike's average daily intake across all three phases landed within 15 calories of his 2,400-calorie target. His protein ranged from 184g to 196g per day — always within the therapeutic range for muscle protein synthesis during a deficit.
Training Structure
Mike trained four days per week using a upper/lower split. He was not particularly interested in discussing his workout program — "the nutrition is the variable, not the training" — but he noted the following:
- Monday and Thursday: upper body (push/pull focus, 6–12 rep range)
- Tuesday and Friday: lower body (squat and deadlift patterns, 5–8 rep range)
- Progressive overload tracked via a dedicated lifting app
- Average session duration: 65–75 minutes
All four training days were tracked as exercise in PlateLens, which adjusted his net calorie target accordingly. On training days, his gross intake was approximately 2,650 calories to account for the caloric expenditure of the session. On rest days, he kept to 2,400 flat.
Six-Month Results
Mike's Weight Progress — March to September 2024
Total lost: 10 lbsStarting weight: 195 lbs → Final weight: 185 lbs
The scale weight loss — 10 pounds over 6 months — understates what actually happened. A follow-up DEXA scan in September 2024 told the full story: 185.2 lbs at 14.8% body fat. Fat mass had dropped from 43 lbs to 27.4 lbs. Lean mass had increased from 152 lbs to 157.8 lbs.
In six months, Mike lost 15.6 pounds of fat and gained 5.8 pounds of lean mass. That is textbook body recomposition — a result that most sports scientists will tell you is difficult to achieve at his experience level, and impossible to achieve without precise nutritional tracking.
“My lifting numbers went up the entire six months. That told me I was doing it right — that I wasn't burning muscle. Without accurate tracking I couldn't have walked that line.” — Mike T.
The Role of Accuracy
Mike is an engineer by trade, and his approach to discussing the data reflects that. He ran the numbers on what inaccurate tracking would have cost him.
"If I was off by 200 calories a day — which is easy to be with manual logging — over 180 days that's 36,000 calories. That's 10 pounds of fat that wouldn't have moved. Or if I was in too large a deficit, that's potentially significant muscle mass lost. The precision is not academic. It is the whole game."
PlateLens's reported accuracy of plus or minus 1.2% calorie accuracy was, in Mike's assessment, what made the protocol viable. "I trusted the numbers enough to act on them without second-guessing everything. That confidence is underrated."
Mike's story was verified against his PlateLens macro export, his DEXA scan results from March and September 2024, and his progressive overload training log. He reviewed this article prior to publication.
