Your Fat Loss Sprint Planner
The research is clear: the majority of diet failures are adherence failures — caused by indefinite timelines, not lack of willpower. The sprint is different.
Standard dieting advice creates an indefinite commitment: eat less, move more, and keep going until you reach your target. No finish line. No defined end. Just discipline, indefinitely.
The Purcell RCT (The Lancet, 2014) found that 18% of gradual dieters dropped out before hitting their target. Of those who completed the full program, many regained. This isn't because those people lacked character. It's because the timeline-to-result ratio makes the gradual approach psychologically unsustainable for a significant proportion of people.
The research also shows something important: the fast initial weight losers — people who lost more in the first month — had higher adherence rates, better long-term outcomes, and were no more susceptible to regain than slow losers (Nackers et al., 2010). Visible, rapid progress reinforces commitment. That's why the sprint often succeeds where slow approaches failed.
The Fat Loss Sprint is not a harder version of slow dieting. It is a different tool:
| Previous Diets You've Tried | Lipoly Fat Loss Sprint | |
|---|---|---|
| Finish line | No | Yes — day 14, 21, or 28 |
| Daily decisions | Many (what to eat, how much, when) | Few — protocol specifies targets |
| Early visible results | Slow or absent | Measurable change in week 1 |
| Protein guidance | Generic or absent | 2.2–3.0 g/kg LBM — calculated for your body |
| Recovery built in | No | Yes — mandatory 14-day Maintenance Phase |
| Success rate | 50% (Purcell 2014) | 81% (Purcell 2014) |
| Dropout rate | 18% (Purcell 2014) | 3% (Purcell 2014) |
Nackers et al. (2010) is particularly relevant for this audience. In a study of weight loss program adherence:
The conclusion: rapid initial weight loss does not set you up for failure. It sets you up for sustained motivation. The serial diet failure pattern is often the result of the wrong tool — not a character flaw.
81% success rate. 3% dropout. The Lancet, 2014. A different category of result.
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.
