What actually is Lina?
Lina is a daily companion for people on GLP-1 medications like Ozempic, Wegovy, Mounjaro, and Zepbound. We help you track what actually matters: protein intake, hydration, side effects, and the non-scale victories that keep you going. Everything is built on behavioral science research. We never make medical claims or give dosing guidance. Think of it as daily support between your doctor visits.
The gap between prescription and persistence
GLP-1 medications work well when patients stay on them. But staying on them is harder than most people expect.
66%
of patients report feeling shame about using weight loss medication, leading them to hide what they're doing and quit treatment early.
Rubino et al., Lancet Diabetes & Endocrinology, 2020
4-6
weeks is when side effects peak and dropout rates spike. Without support during this window, many patients conclude the medication "isn't for them."
GLP-1 Clinical Literature Review
The emotional side
Clinical trials don't capture what it actually feels like. Many people hide their GLP-1 use, which creates isolation right when they need support most. The internal dialogue doesn't stop: "Is this cheating? What happens when I stop?"
Your prescriber has fifteen minutes with you every few months. The emotional side of this process needs daily support.
Lina fills this gap. We're there every day, between the appointments where clinical care happens.
How tracking non-scale victories builds lasting habits
The scale fluctuates with hydration, hormones, and time of day. It can't tell you that your energy is better or your clothes fit differently. Non-scale victories are often the more meaningful signs of change.
66
days on average
How long it takes for a new behavior to become automatic. Not 21 days as the myth goes.
Lally et al., 2010
2-3x
better follow-through
When people decide in advance when and where they'll perform a behavior.
Gollwitzer, 1999
50-100%
improved outcomes
Self-monitoring improves weight management outcomes. The single strongest predictor of success.
Burke et al., 2011
The Lina habit loop
1. Track a non-scale victory
Notice something good that has nothing to do with a number. More energy, jeans fitting differently, making it through the afternoon without sugar. These moments slip by when you're only watching the scale.
Celebrating small wins triggers dopamine release, reinforcing the behavior. Woolley and Fishbach (2018) found this makes habit formation 2.5x more likely to succeed.
2. Build pattern awareness
Patterns emerge that were always invisible. Your energy crashes without breakfast protein. Your mood lifts when you drink enough water. Lina surfaces these connections so you can actually see what's working.
Burke et al. (2011) found self-monitoring is the strongest predictor of successful weight management, improving outcomes by 50-100%.
3. Create daily consistency
One good day doesn't do much. A hundred ordinary days does. Lina's check-ins take less than a minute, but that minute repeated across months adds up. The streak system makes consistency visible.
Lally's study (2010) found it takes an average of 66 days for a behavior to become automatic, ranging from 18-254 days depending on complexity.
4. Stack new habits
Attach new habits to ones you already have. Log protein while you eat breakfast. Do your check-in while coffee brews. You're not adding more to your day, you're fitting things into gaps that already exist.
Gollwitzer's research (1999) showed "when-then" planning increases follow-through by 2-3x.
5. Build health identity
At some point, you stop saying "I'm trying to be healthier" and start saying "I take care of my health." That shift comes from repeated action, not affirmation. What you do every day becomes who you are.
Oyserman's research (2006) found connecting behavior to identity improves long-term adherence by 40%.
6. Achieve sustainable outcomes
The weight changes. The health scores improve. But by this point, those outcomes feel like side effects of how you live, not goals you're grinding toward. The habits carry the weight.
Ryan and Deci (2000) found intrinsic motivation predicts 3x better long-term weight maintenance than extrinsic motivation.
Why the scale fails
People who focus on how they feel (energy, mood, daily function) show 3x better long-term weight maintenance than those focused on scale numbers. The scale tells you what happened. Non-scale victories tell you what's actually changing.
Ryan & Deci, 2000
Small wins compound
Each non-scale victory triggers dopamine release, and your brain starts encoding the behavior that led to it. Over time, healthy choices become rewarding on their own instead of something you have to force.
Woolley & Fishbach, 2018

How we calculate your goals
Personalized targets based on published research
Protein Goals
Preserving muscle during GLP-1-induced weight loss matters. Lina calculates protein goals using:
Formula: 1.2g protein per kg of current body weight
This multiplier sits in the middle of the 1.0-1.6g/kg range recommended for muscle preservation during weight loss. Goals automatically adjust as users log new weights.
Minimum: 50g/day
Absolute floor for any adult
Maximum: 120g/day
Practical ceiling accounting for GLP-1 appetite suppression

Calorie Goals
For users who opt into calorie tracking, Lina calculates goals using the Mifflin-St Jeor equation, the most widely validated formula for estimating BMR.
BMR = (10 × weight in kg) + (6.25 × height in cm) - (5 × age) - 161
TDEE = BMR × activity multiplier
Goal = TDEE - 500 kcal (moderate deficit for ~0.5kg/week loss)
Activity multipliers (Harris-Benedict revised):
Sedentary
1.2
Lightly active
1.375
Moderately active
1.55
Very active
1.725
Note: GLP-1 medications already reduce appetite, so a moderate deficit is appropriate. We never push users toward extreme restriction.
BMI with ethnicity-adjusted thresholds
Standard BMI cutoffs were developed primarily using White European populations and don't reflect equivalent cardiometabolic risk across ethnicities. Lina uses research-based ethnicity-specific thresholds.
Thresholds (based on equivalent T2DM risk to BMI 30 in White populations):
White
30
Black
30
South Asian
23.9
Chinese
26.9

Health score and AI food insights
How we help patients understand their food choices
Lina's AI meal analysis gives each logged meal a Health Score from 0-100. The score reflects nutritional quality without moral judgment.
How it works
- Users photograph or describe their meal
- AI estimates nutritional content using USDA standard reference values
- A health score is calculated based on protein/fiber content, sugar/sodium levels, and whole vs. processed food indicators
Score ranges
70-100
Nutritious
High protein, fiber, whole foods
40-69
Moderate
Some processed elements
0-39
Consider Alternatives
High sugar, fried, ultra-processed
Important framing: The score is labeled as "an estimate to help guide healthier choices," not a medical assessment. The goal is to inform without shaming.
