We might have to agree to disagree. Living frugally means separating needs from wants, figuring out when you need something so you have time to buy at a discount. If buying just something you just want, you set a max for what you're willing to spend. Sure sounds like managing your income, aka budgeting. And about the diet analogy. Living frugally is analogous to eating a healthy diet where you get your necessary nutrients and calories. What you're suggesting is excessive eating, while working out hard, as long as the calorie balances out (obviously not that healthy.)
