The difference between "lose" and "loose"... 
: to be unable to find (someone or something) 
: to fail to win (a game, contest, etc.)  
: to fail to hold on to (something wanted or valued)
: not tightly fastened, attached or held  
: not pulled or stretched tight
Please understand the difference. 
You can "lose" weight, hope, a fight, your keys, etc.
You cannot "loose" any of the above. 
Thank you 💋
