Lipoly
Your Fat Loss Sprint Guide
You don't need a coach to follow a proven protocol. You need a structured app with a defined finish line.
Diet coaching apps typically charge $100–$400/month (prices vary by provider) for registered dietitian check-ins, behavioural coaching, and food logging support. The model is built on ongoing engagement — which means ongoing billing.
Lipoly is built on the opposite model. It calculates your sprint targets from your body composition, guides you through 14–28 days of structured protocol, and then — you're done. You graduate off the app. That's the design. No perpetual subscription model. No coach dependency.
The Fat Loss Sprint protocol is built on 50+ years of PSMF clinical research. The same science that PSMF coaches and clinics charge $1,000–$5,000 to administer, Lipoly provides for $29.99/month — or $149.99 once, for life.

| Science basis | Behavioural / lifestyle | PSMF: Harvard (1970s) → Lancet RCT (2014) |
| Cost | ~$100–$400/month (varies by provider) | $29.99/month · $149.99 lifetime |

The Protein-Sparing Modified Fast was developed at Harvard Medical School in the 1970s by Dr. George Blackburn and Dr. Bruce Bistrian. It has been studied in hundreds of published trials, endorsed by NICE (UK), EASO, and AHA/ACC.
Purcell et al. (The Lancet, 2014): 81% of rapid protocol users hit their fat loss target. 50% of gradual coached dieters did — in three times the time, at ongoing subscription cost.
Lipoly packages this protocol into a $30/month app. The science doesn't require an expensive coaching subscription. It requires following it.
