Start with lesson 1Negative Caloric Balance (Caloric Deficit)Free to read. Track it in Studio to save progress and practice each checkpoint.
1EssentialsThe energy-balance concepts every fat-loss approach depends on. · 2 core lessons
- 1Negative Caloric Balance (Caloric Deficit)You lose body fat only when you burn more energy than you eat: a caloric deficit. Combine eating less with being more active, keep lifting and eat plenty of protein so the loss is mostly fat. Expect weight loss to slow over time even if you keep the same deficit.6 min · Nutrition6 min · Nutrition
- 2Setting Calorie Targets for Fat Loss, Maintenance, and GainEstimate maintenance, then pick a rate rather than a number: lose about 0.5–1% of body weight per week, or gain about 0.25–0.5% per week. Start near maintenance ±500 kcal, then let your 2–3 week weight trend tell you whether to adjust.8 min · Nutrition8 min · Nutrition
Stage checkpoint · Your energy-balance sketch
In your own words, explain where your daily energy goes and which one or two levers you can realistically change. No calorie target needed.
Practice it in Studio2ApplicationTurn the deficit into a real nutrition and training plan. · 4 core lessons
- 1Nutrition for Fat LossFat loss requires a moderate calorie deficit with high protein, plenty of fiber and volume, and an approach you can sustain while training to keep muscle.4 min · Nutrition4 min · Nutrition
- 2Cutting (Fat-Loss Phase)A "cut" is a deliberate fat-loss phase run in a moderate deficit with high protein and maintained training, to reveal muscle built during a gaining phase.3 min · Nutrition3 min · Nutrition
- 3Fat-Loss ProgramA resistance-led plan inside a moderate calorie deficit, with adequate protein and added cardio, designed to lose fat while keeping the muscle you have.2 min · Programming2 min · Programming
- 4KPIs for Fat LossTrack the bodyweight trend + waist + photos to confirm fat is leaving, and nutrition adherence + step floor as the controllable inputs driving it.2 min · Tracking2 min · Tracking

- 1Cardio for Fat Loss vs. FitnessTraining to get fitter and training to lose fat are different jobs — fitness is driven by intensity and progression, while fat loss is driven by total energy balance, so the best cardio choice depends on the goal.2 min · Cardio2 min · Cardio
- 2LISS (Low-Intensity Steady State)Easy, conversational, continuous cardio held at a low intensity for a longer time — gentle on the body, sustainable, and the easiest aerobic dose for beginners.2 min · Cardio2 min · Cardio
- 3Body Recomposition"Recomp" is gaining muscle and losing fat at the same time — most achievable for beginners, returnees, and higher-body-fat individuals with high protein and training.2 min · Nutrition2 min · Nutrition
Stage checkpoint · One realistic week
Sketch a week that keeps your strength training in and adds one sustainable change to food or activity. Note how you will know it is working.
Practice it in Studio3TroubleshootingThe myths that waste effort, and how to read the scale honestly. · 4 core lessons
- 1Spot Reduction (Myth)Exercising a body area does not reliably preferentially burn fat there; fat is lost from all stores in a genetically determined pattern, generally first from where it was last deposited — the evidence is overwhelming but, per a small 2023 RCT, not 100% closed.3 min · Nutrition3 min · Nutrition
- 2Low- vs. High-Intensity Fat-Burning MythLow-intensity exercise burns a higher percentage of calories from fat, but higher-intensity exercise burns more total calories and more total grams of fat — and you lose weight by burning more than you take in.2 min · Nutrition2 min · Nutrition
- 3Interpreting Weight FluctuationsDay-to-day scale swings are mostly water, glycogen, gut contents, and sodium — not fat gain or loss, which changes slowly.2 min · Tracking2 min · Tracking
- 4NEAT (Non-Exercise Activity Thermogenesis)NEAT is all the energy you burn moving that isn't formal exercise — walking, fidgeting, posture, chores — and it's a large, variable slice of daily burn that quietly drives fat-loss results.2 min · Tracking2 min · Tracking

- 1Fatness and FitnessThe goal of a weight-loss program should be a real change in body composition (fat loss), achieved through a sustained negative energy balance, not the meaningless initial water-weight drop.1 min · Nutrition1 min · Nutrition
- 2Rethinking Weight ControlWeight control is still worthwhile for health, but success comes from changing clients' ideas about food, fat, and fitness — not from another diet.1 min · Nutrition1 min · Nutrition
- 3Sweat Rate Is Not a Fat-Loss Gauge (Myth)Sweat is a cooling response driven by heat, humidity, clothing, and individual sweat-gland variability — not by how many calories or how much fat you're burning — so a soaked shirt tells you almost nothing about the workout's fat-loss value, and the pounds it costs on the scale are water, not fat.4 min · Conditioning4 min · Conditioning
Stage checkpoint · Myth check
Name one fat-loss claim you have believed. Explain what this stage says about it and what you will do differently.
Practice it in Studio4AdvancedAdvanced dieting and timing strategies once the basics are dialed in. · 3 core lessons
- 1Fasted Cardio and Fat LossFasted cardio does shift the fuel mix toward burning more fat during the session, but controlled trials find that doesn't translate into more fat lost over weeks when total calories and macros are matched — this is a genuinely contested claim where the mechanism is real but the outcome it's supposed to produce mostly isn't.7 min · Cardio7 min · Cardio
- 2Intermittent FastingEating within restricted time windows can aid fat loss mainly by cutting total calories; it offers convenience for some but no proven metabolic edge when calories match.3 min · Nutrition3 min · Nutrition
- 3Low-Carbohydrate and Ketogenic DietsRestricting carbohydrates (very strictly in keto) can aid weight loss and blood-sugar control, mainly by reducing calories — not through metabolic magic.2 min · Nutrition2 min · Nutrition
Stage checkpoint · A lever you would test
Choose one advanced strategy from this stage and describe who it suits, who it does not, and how you would try it safely for two weeks.
