Weight predictor for adults
See where your weight is heading.
SlimAhead is an app that shows your future weight. Set your own goal and your own timeline, whether that is a few weeks or nine months away, and get a personal plan for how to eat to get there.
How it works
A forecast first, then a plan built around your goal. No food diary is needed to get started.
Answer a few questions
Age, sex, height, weight, and how active you are. It takes a couple of minutes.
See your future weight
Where your weight is heading over the coming weeks and months if nothing changes.
Set your goal
Choose a goal weight and the date you want to reach it. SlimAhead builds a personal eating plan for that timeline, within safe limits.
Weigh in over time
Each weigh-in helps your forecast and your plan adjust to how your own body responds.
What makes it different
Most weight apps look back at what you already did. SlimAhead looks forward.
Ranges, not a single number
Body weight moves from day to day with water and food. SlimAhead shows a likely range so the forecast stays honest.
Built on published research
The forecast uses a published mathematical model of how body weight responds to changes in energy intake and activity (Hall et al., The Lancet, 2011).
It learns from you
General science is the starting point. As you log weigh-ins, the forecast is recalibrated to your results.
SlimAhead is an independent product. It is not affiliated with or endorsed by the researchers or institutions whose published work it draws on.
For adults, and not medical advice
SlimAhead is for people aged 18 and over. It gives general wellness information and estimates. It does not provide medical advice, and it does not promise any result.
Please talk to your doctor before changing how you eat or exercise if you are pregnant or breastfeeding, have a medical condition, have or have had an eating disorder, or take medication that affects your weight or appetite.
