Other brothermen have said the same things so I'll be brief (BOC gif), but I think it's a coin toss between two different weight-loss approaches. Both worked for me with similar results.
1) keto. you'll find that you're so sated on eating nothing but meats, butter, veggies, and eggs (beware of sugars in deli meats, sauces, etc) that calorie counting is pointless. You won't eat as much so your body burns off the fat stupidly quick. Downside, it's strict. You need to stay in ketosis and one sip of sugary cum throws it all off. It's too restrictive for some people, but I liked knowing exactly what I could and couldn't eat after a while.
2) calorie counting. It's a pain to track every fucking thing you throw down your gullet, but that actually keeps you from grabbing snacks and treats here and there. When you start adding foods into a spreadsheet, you'll see how calories add up. So you'll pay more attention to the things you eat (and drink, ya lush!). Also, proteins like eggs and meat are low in calories anyway so you'll end up eating a ton like you would on keto. With the added benefit of not worrying about ketosis, so you can have a bagel, yogurt or something sweet here and there.
Both worked for me. I lost 30 lbs in two months (215 to 185 lbs) keeping my average calorie intake ~1500/day. But on keto, my love handles melted off in half the time. I was never fat, but switching from an active job to a sedentary one while eating the same took its toll.
Fun fact: Do you think fat leaves your body through pissing, pooping or sweating? Nope. It leaves through breathing. You exhale fat!
