“Brenda lost 10 kg and I lost 5 kg.” That sounds lopsided—until you realize Brenda started 40 kg heavier. Percent lost tells the fair story.

Why percent beats raw kg/lb

• Normalizes for starting point: 5% is meaningful whether you started at 70 kg or 120 kg.
• Lines up with health milestones: Many clinical goals use 5% and 10% benchmarks.
• Cleaner cohort comparisons: Percent lets you compare apples to apples.

How we show it

• Your dashboard highlights % from baseline.
• Cohort charts use percent so your line sits next to “people like you” fairly.
• We still show kg/lb in your logs—because both views help.

A quick example

• Person A: 120 kg → 114 kg (−6 kg = 5%)
• Person B: 80 kg → 76 kg (−4 kg = 5%)
  Same 5% means similar progress.

If your scale jumps up after a good week, you didn’t “ruin everything.” Most day-to-day swings are water, not fat. Understanding that difference keeps you consistent.

What drives short-term ups/downs

• Sodium & carbs: Higher salt or carb meals pull water into glycogen stores. Expect a 1–2 day bump.
• Hormones & cycles: Many see predictable monthly fluctuations.
• Training: Hard workouts cause tiny muscle damage → temporary water retention for repair.
• Travel & sleep: Long flights, poor sleep, stress → transient water shifts.
• Timing: Weighing after a late dinner or earlier than usual can throw things off.

What reflects actual fat change

• The trendline (7-day moving average)
• Weekly velocity (kg/week over the last 4 weeks)
• Percent lost from your starting weight

How to keep your head when it blips

• Look at weeks, not days.
• Tag behaviors (walk, late dinner, alcohol, travel) so your 48–72h impact cards make sense of blips.
• Celebrate streaks, not perfect lines.

Comparisons can motivate—or demoralize. We designed cohorts to be useful and kind.

What’s a cohort here?

It’s an anonymized group that matches you on: age band, sex, country, starting BMI band, medication, and current dose. We align everyone by weeks since they started so the timeline makes sense.

What you’ll see

• Your line: percent from baseline since you started.
• Cohort band: the shaded area shows the 10th–90th percentile; a darker band shows the IQR.
• Tiles: your % lost, cohort median, recent velocity, and (when available) typical time-to-5%.

Why some charts don’t show

Privacy first: we suppress any cohort view where n < 30 (often 50). If data are thin, we’ll widen the cohort slightly or simply say “not enough data yet.”

How to use it

• Ahead of median? Great—keep the habits working for you.
• Below the band? It happens. Check tags, sleep, dose timing, stress, travel. Consider a chat with your clinician.
• Up and down days? Normal. Look at weeks, not days.

Fair expectations

Cohorts are observational data, not randomized trials. They’re great for context, not prescriptions.

Medications like semaglutide and tirzepatide have changed the conversation around weight management. Here’s a plain-English primer to help you talk with your clinician and set expectations.

What these meds do (high level)

They affect appetite and satiety signals. Many people feel full sooner and find it easier to stick to routines. Response varies—some see steady progress, others need dose adjustments or different approaches.

Why titration is slow

Doses usually increase gradually to reduce side effects (nausea is common early on). Your clinician sets the pace based on your response and tolerance.

What we show in the app

• Your trend (percent from baseline) and recent velocity.
• Cohort context by medication and dose (when samples are large enough).
• Dose ladder views: what community data looks like as people move through doses.

What this is not

We don’t tell you what to take or when to change a dose. We simply show community patterns and your own trend so you can have a better conversation with your clinician.

I didn’t set out to build a website. I set out to get healthier.

I started logging my weight every day and measurements every month. I kept notes on what I ate, when I walked, and how I felt. Patterns began to appear—slowly at first, then clearly: certain habits nudged the scale one way or the other within a couple of days.

I wanted more than a lonely graph. I wanted context: How do people like me typically progress? What happens after a week of evening meals? Does a daily walk matter over time? That’s how Together We Lose began.

What makes this different

• Compare with people like you. We show anonymized cohort curves—by age band, sex, country, starting BMI band, medication and dose—so you can see where you stand without judgment.
• Behavior tags → insights. Simple tags like walk, late dinner, alcohol, travel turn into 48–72-hour impact cards you can actually use.
• Privacy first. We bucket counts, suppress small samples, and never show individual logs publicly.
• Kind, not punitive. We reward consistency and learning—not “biggest loser” bragging.

What you can expect

• A fast, mobile-friendly logger you can install to your home screen.
• Personal trendlines and weekly velocity.
• Cohort comparisons that grow smarter as the community grows.
• Optional teams, streaks, and gentle challenges.
