FAQ
Reader questions
How many weekly HIIT sessions are safe for most adults?
Two to three quality HIIT sessions per week, spaced with lower intensity work, suit many healthy adults.
Can improving sleep really accelerate fat loss in a calorie deficit?
Yes, better sleep supports adherence, hormone balance, and energy levels, which can enhance fat-loss outcomes.
Are plant-based proteins sufficient for strength and recovery?
Yes, combining varied sources throughout the day delivers adequate amino acids for muscle repair and growth. Current devices are generally within about 5% of lab measures, making them useful for tracking trends rather than exact values.
