Perguntas comuns
Does fasting really reduce calorie intake?
Yes. Research consistently shows that restricting eating windows naturally reduces calorie intake by 10-40% depending on the protocol, primarily by eliminating late-night snacking and reducing the number of meals. Most people do not fully compensate by eating more during their eating window.
What is the best fasting protocol for beginners?
16:8 is the most popular starting protocol — you fast for 16 hours and eat within an 8-hour window. Most people achieve this simply by skipping breakfast. Start with 14:10 if 16 hours feels too long and gradually increase your fasting window over 2-3 weeks.
Will I lose muscle while fasting?
Short-term fasting (up to 24 hours) does not cause significant muscle loss if you maintain adequate protein intake during your eating window. Aim for 1.6-2.2g of protein per kg of body weight. Resistance training during your eating window also helps preserve muscle mass.
Does fasting slow down metabolism?
Short-term intermittent fasting does not significantly reduce metabolic rate. Some studies suggest fasting for 12-36 hours may actually slightly increase metabolic rate due to norepinephrine release. Prolonged calorie restriction (weeks of very low intake) is what slows metabolism.
