Your Fat Loss Sprint Planner
Lose It records what you ate. It doesn't tell you what to eat, when to stop, or how to recover. The sprint does all three.
Lose It! is a solid calorie tracker — accurate, well-designed, and widely used. But like all general trackers, it has no opinion about what you should eat, when your diet should end, or how to recover when it does. It records decisions. It doesn't make them.
Most people tracking calories run a 300–500 kcal daily deficit. At that pace, 10 kg of fat loss takes 4–6 months. The Purcell RCT (The Lancet, 2014) showed 18% of gradual dieters drop out before hitting their target. Not because of the tracker — because the timeline destroys adherence.
Lipoly calculates your sprint targets from your body composition, structures 14–28 days of protocol-driven restriction, schedules refeeds automatically, and builds in a mandatory 14-day Maintenance Phase. It's not a better tracker. It's a different category of tool.
| Lose It! | Lipoly | |
|---|---|---|
| Function | Calorie and macro logging | Structured fat loss protocol with calculated targets |
| Macro targets | User-set or generic TDEE estimate | Personalised from body fat %, sex, and LBM |
| Protocol | None | Tracking Phase → Sprint → Maintenance Phase |
| Defined end date | No | Yes — 14, 21, or 28 days |
| Training | Logged, not guided | Structured strength program, 2x/week required |
| Supplementation | No | Full stack required — tracked daily |
| Refeeds | No | Auto-scheduled per Sprint Level |
| Recovery phase | No | Mandatory 14-day Maintenance Phase |
| AI meal planner | Barcode scanner / food diary | Plan meals in plain English to hit your daily targets |
| Cost | Free–$40/year | $9.99/wk · $29.99/mo · $199 lifetime |
Tsai & Wadden (2006): structured VLCD produced 16.1% body weight loss vs. 9.7% for conventional calorie counting over the same period.
Purcell et al. (2014) compared rapid vs. gradual caloric restriction approaches: 81% vs. 50% target achievement rate; 3% vs. 18% dropout. These figures apply to rapid and gradual dietary protocols respectively — not to any specific app or service.
The Fat Loss Sprint is built on the Protein-Sparing Modified Fast — clinical research from Harvard Medical School (1970s) through modern RCTs. 50+ years of evidence that the slow-and-steady assumption is not the only legitimate approach.
Most food logging apps are built to be used forever — the logging never ends. Lipoly is designed to be finished. The sprint teaches you real food quantities and portions that match your body's targets. The Maintenance Phase teaches you what sustaining results actually looks like. You leave the app with that knowledge. · Personalised targets. Defined finish line. Mandatory recovery. 50+ years of PSMF science.
The Protocol
Your macros, protein target, and sprint length aren't guesses — they're set by the Fat Loss Sprint, a protocol built on 50+ years of clinical research. See how it works, and how it compares to every other diet.
