In stead of keeping up with receipts. Am I able to use my bank statements? For meals, fuel, clothing, etc...

Maybe for your bookkeeping however if you are ever audited the IRS requires the actual receipts ( you can scan them and keep the records electronically).    https://www.irs.gov/taxtopics/tc305

For instance you may have a charge at Walmart  but unless the IRS can see what you bought they will assume it was all personal purchases and disallow any business deduction.   https://www.irs.gov/publications/p583#en_US_201408_publink1000253160

For most expenses, bank records (cancelled checks, or credit/debit card statements) are adequate. Two notable exceptions: 1) Hotel expenses require itemized receipts; 2) Amounts over $600 paid to Persons for help in your business require you to file/issue 1099-MISC to IRS and person.
