The funny thing, it's not hard to eyeball stuff while cooking. I've been cooking 95% of my meals at home, from scratch, for over a decade. I can free-pour a tbsp of oil to ~1ml accuracy, or oz's of liquid, for that matter. Use measuring cups for everything, and have looked this shit up enough times to know it off by heart (an egg is 70 cal, a tbps of butter is ~100cal, the average strip of bacon is ~80cal, a 0.25lb burger patty is ~300cal, etc). It's not hard once you do it for a while; it becomes second nature. Wanna know my super, top-security-clearance, fat-melting, ultra-secret secret to losing weight, and keeping it off? I round up. Two slices of bread for this sandwich... 170? 160? 180? Fuck it, 200 calories. Especially when it comes to losing weight, why in the name of all that is holy, would you round down, or even just not even bother knowing the ballpark of the calories of what you're eating contains. It's just pure stupidity and laziness. But, what else would you expect from a ham.
