On Ozempic, Wegovy, or Mounjaro, you're not at risk of eating too much — you're at risk of eating too little of the right things. tr8ck tracks protein, nutrient density, and energy impact of your diet so you protect muscle, prevent hair loss, and stay energized while losing weight.
Most nutrition apps are built for calorie restriction. GLP-1 users need the opposite focus — preventing under-nutrition, not over-eating.
Celebrates eating under 1200 calories as success — on GLP-1, this often means dangerous under-nutrition
Tracks total calories as primary metric — misses protein deficiency until muscle loss and hair loss occur
Doesn't connect food intake to energy levels, mood, or medication side effects
No injection cycle awareness — treats every day the same, ignoring that GLP-1 users have dramatically different appetite across the week
Protein is the primary metric — alerts when daily intake falls below your personal target (default 80–120g)
Minimum calorie floor alert — warns when you've been under 1200 calories for multiple consecutive days
AI correlates nutrition with energy score, mood, and weight loss rate — shows you what eating more protein actually does to how you feel
Injection cycle context — tracks which days in your injection cycle you eat less, helping you plan high-protein small meals for low-appetite days
Not all nutrition metrics matter equally on GLP-1. Here's what to track and in what order of importance.
Target: 80–120g/day. Prevents muscle loss, hair loss, fatigue, and poor recovery. This is the single most important number for GLP-1 users to track. Even a rough log (estimating grams per meal) is far better than not tracking at all.
Floor: 1200–1400 calories minimum for most adults. Not a ceiling — a floor. Staying below this consistently depletes micronutrients, causes fatigue, slows metabolism, and accelerates muscle loss. GLP-1 appetite suppression makes going below this dangerously easy.
Target: 2–3 liters/day. GI side effects and reduced food intake (food contains water) both reduce hydration. Dehydration contributes to fatigue, headaches, constipation, and impaired cognition — all common complaints on GLP-1 that are often nutrition/hydration issues, not medication issues.
When eating small amounts, every bite counts. Log meal quality — is each meal protein-rich, vegetable-inclusive, and micronutrient-dense? The few hundred calories you do eat should come from nutrient-dense sources, not empty foods. tr8ck's nutrition module supports quality ratings alongside macros.
Both apps track nutrition, but they're designed for fundamentally different goals. See how they compare for GLP-1 use.
| Feature | MyFitnessPal | Cronometer | tr8ck |
|---|---|---|---|
| Protein-first tracking | Calories first | Good micronutrient detail | Protein as primary metric |
| GLP-1 injection integration | None | None | Full injection cycle context |
| Energy/mood correlation | None | None | AI cross-module insights |
| Sleep & exercise connection | Separate (Apple Health sync only) | Limited | Native in same app |
| Minimum calorie floor alert | No (celebrates low calorie) | No | Yes — GLP-1 optimized |
| Medication side effect tracking | None | None | Full side effect log |

tr8ck's AI surfaces correlations between your food intake and every other health dimension — automatically, without manual analysis.
After 2–3 weeks, tr8ck shows the correlation between your daily protein intake and energy score. Most users discover a clear threshold: below a certain protein level, energy reliably drops. Seeing your personal number is far more motivating than generic advice.
Low calorie intake and poor sleep are connected — under-eating can increase nighttime waking and reduce sleep quality. tr8ck correlates nutrition logs with sleep quality scores to reveal whether your eating patterns are affecting your sleep on GLP-1.
Low protein days consistently correlate with worse exercise performance and slower recovery. tr8ck shows which days you logged lower workout scores and what you ate beforehand — making the protein-performance connection concrete and personal.
Extremely low calorie intake can paradoxically slow fat loss by triggering metabolic adaptation. tr8ck correlates nutrition adequacy with weekly weight loss rate to identify if you're in an optimal intake range — not too high, not dangerously low.
Nutrition is one of 13 health dimensions tr8ck tracks simultaneously.
Traditional calorie counting is less relevant on GLP-1 — the medication naturally controls intake. What matters is tracking protein (to prevent deficiency) and ensuring you're above a minimum calorie floor (1200–1400/day). Think of it as nutritional safety monitoring rather than restriction tracking.
The clinical recommendation is 80–120g of protein per day minimum, scaling with body weight (roughly 0.7–1g per pound of goal body weight). This is challenging on GLP-1 due to appetite suppression — protein shakes, Greek yogurt, eggs, and lean meats eaten in small, frequent amounts are the most practical approach.
tr8ck is the most complete option because it connects nutrition to all other health modules. Unlike calorie-counting apps, tr8ck prioritizes protein, alerts on minimum calorie floors, and uses AI to show how your nutrition affects energy, mood, and weight loss rate — giving Wegovy users context, not just numbers.
Nutrition tracking is arguably more important on GLP-1 than off it. Appetite suppression makes it easy to chronically under-eat protein and calories without realizing it — leading to muscle loss, hair loss, and fatigue. Tracking creates the visibility needed to catch these issues before they become significant problems.
Log even tiny meals and snacks — don't wait for a full meal to log. tr8ck's quick-log feature lets you record food in under 60 seconds. On very low appetite days, focus on logging protein sources. A partial log is always better than no log, and the habit of logging often motivates slightly more intentional eating.
tr8ck's nutrition module is built for the unique challenges of GLP-1 users — protein-first tracking, minimum calorie alerts, and AI correlation with your energy, mood, and weight loss progress.
