Sustainable Weight Loss
Like Duolingo, but for Sustainable Weight Loss. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
For the part of you with thirty open tabs that never became anything.
A short one: 12 levels across 2 sections, about 24 minutes end to end, roughly 5 days at five minutes a day. It moves through Making Deficits Work in the Real Body and Overcoming Plateaus and Ending the Diet. It assumes you already know the basics.

Key ideas in Sustainable Weight Loss
- Packaged food labels can legally misreport calorie counts by up to 20 percent.
- Small inaccuracies in daily portion logs easily wipe out razor-thin calorie deficits.
- A moderate deficit buffer protects fat loss progress against unseen reporting drift.
- Protein demands the highest thermic cost to break down, burning up to 30% of intake.
- Dietary fats require minimal metabolic processing, costing under 3% of their energy.
- Shifting macro ratios toward protein increases net energy burn without cutting food volume.
- Dieting triggers a subconscious drop in non-exercise physical activity like pacing.
- Weekly calorie budgets allow trimming small daily amounts to save for social events.
- Reduced spontaneous movement can quietly erase hundreds of calories of planned deficit.
- Tracking daily step counts helps maintain baseline physical output during a cut.
- Shifting intake across days preserves fat loss without requiring harsh weekend rebound fasts.
- Flexible weekly planning prevents the psychological collapse of all-or-nothing dieting.
- Carbohydrates bind roughly three to four grams of water per gram of stored glycogen.
- High sodium intake causes temporary fluid retention that masks tissue fat loss on the scale.
- A rolling seven-day scale average filters out erratic water weight spikes from true fat loss.
- Severe caloric deficits force the body to cannibalize lean muscle for up to 25% of total weight lost
