A note on these estimates
These are estimates based on standard metabolic formulas and research on intermittent fasting outcomes. Real-world results vary significantly based on genetics, stress, sleep quality, hormonal factors, and many other variables.
The biggest factor isn't the protocol — it's consistency. A 14:10 fast done every day will outperform a 20:4 done sporadically. Choose the protocol you can actually maintain, and let the results compound over time.
The first 1–2 weeks often include water weight loss, which can make early results seem dramatic. After that, expect steady, sustainable progress. If the scale stalls, body composition may still be changing — focus on how you feel and how your clothes fit.
