The fundamental question is whether you regard the act of loaning the money as an expense that must be budgeted for. If the loan is not really an expense to you, it looks like this:
1. Create an account for the loan. It might have a title like, "Loan" or "Receivable." If you're doing this with multiple people, you might have "Receivable--John" and "Receivable--Marsha."
2. Say you loan $200 to Marsha. Create a transfer from Cash or Checking (wherever the money came from) to Receivable--Marsha. There is no budget impact. Your money has just shifted from being in your pocket or in your checking account to being in Marsha's custody. But it's still your money.
3. If Marsha gives you $50 cash as a payment on the loan, you record a transfer from Receivable--Marsha to Cash. If Marsha writes you a check and you deposit it in your checking account, that's a transfer from Receivable--Marsha to Checking.
4. If Marsha buys $46 worth of groceries for you (either she gives you the receipt or you agree on the value), you record the transactions as an outflow in the Receivables--Marsha account, with payee of Grocery Store and category of Groceries. That reduces the balance of Receivables--Marsha (i.e., you show that she owes you less) and shows the money as spent from your groceries category.
5. If you're charging Marsha interest, you would record the interest as Income (supplemental or primary, according to your tastes) in the Receivables--Marsha account. Everything else would be as described above.
This should be pretty clean as long as you don't loan out so much money that it gives you cash flow problems with your own expenses.
If you regard the act of extending a loan as an expense, it gets more complicated. As I think about it, that has some different scenarios depending on how often you loan money, whether you want to use the budget to limit how much you loan, and so on. Let us know if that's the road you want to take, and I'll try to figure it out for you. But from your initial description, I think that this is not where you want to go.
