I think a better question is, “how do I lose a minimum of 10lbs of fat for good?”
‘cause let’s be serious, if you lose it in one week, it will come back with friends and vengeance.*
*note: if this is for an athletic competition or astronaut job interview weigh-in or other extraneous, finite event, your question is fine as it is. My answer is for the general population aiming to turn a few more heads than last week.
To lose 10# of fat for good, try these steps:
Above all else, be patient and keep it real.
A goal like “lose weight” is ambiguous and non-actionable.
A goal like “sleep 7 hrs 5 to 6 days per week” is something you can have a strategy for and track.
When you take the time to develop these habits, you’ll lose more than weight. See: stress, struggle, strife.
