Business loans are advisable only after testing a business idea and finding out it's worthy of testing out, for example if you want to start selling online and you've found a prototype that works, you can take a loan to start the business properly, since you have a proof it's going to work.
It's not advisable to just take loans to start a business you have no knowledge on and no any clear plan on how to pay the loan back, you'll end up indebted and bank may decide to confiscate your collateral till you settle your loan, overall it's not a good idea.
