Lipoly
Your Fat Loss Sprint Guide
One meal a day is aggressive. Aggressive with calculated protein, structured training, and a finish line is better.
OMAD creates a large caloric deficit through timing — one eating window forces lower total intake for most people. The problem: fitting adequate protein into a single meal is genuinely difficult. Most OMAD practitioners eat 80–120 g of protein per day, well below the lean mass preservation threshold during severe restriction.
The consequence: lean mass loss alongside fat loss. Muscle has a metabolic cost — losing it slows your resting metabolic rate and makes long-term maintenance harder. The Fat Loss Sprint targets 2.2–3.0 g/kg LBM of protein, spread across multiple eating occasions during the day, to maximally protect lean mass during aggressive restriction.
The other issue: OMAD has no defined end. The protocol runs indefinitely. The FLS is 14–28 days — then a mandatory 14-day Maintenance Phase.
| OMAD | Lipoly Fat Loss Sprint | |
|---|---|---|
| Restriction mechanism | One eating window per day | Calculated caloric target from body composition |
| Protein | Often insufficient in single meal | 2.2–3.0 g/kg LBM — spread throughout the day |
| Calories | Often untracked | Precisely calculated |
| Lean mass protection | Poor (insufficient protein) | High — protocol mandates protein + strength training |
| Training | Not specified | 2x/week strength — required |
| Duration | Indefinite | 14–28 days, defined end |
| Refeeds | None | Scheduled mid-sprint + final day |
| Recovery phase | None | Mandatory 14-day Maintenance Phase |
Mettler et al. (2010): athletes on identical caloric deficits — high protein group (2.3 g/kg) retained significantly more lean mass than standard protein group (1.0 g/kg). The difference wasn't the calories. It was the protein.
Longland et al. (2016): At a 40% caloric deficit with high protein (2.4 g/kg) and resistance training, participants gained 1.2 kg of lean mass while losing 4.8 kg of fat. OMAD cannot achieve this without protein precision and training structure.
