Sustainable Weight Loss, a free health course on Tomo

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.

What you'll learn

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
