Hmm... Some statements about excluding cardio almost entirely, imho, seem out of place on a generic fitness thread such as this. Beginners need to start off with a more balanced approach. Advanced enthusiasts can choose what works better for them, of course. But they are probably not visiting this thread here on TE seeking advice.
When it comes to fitness, it's best to avoid making any sweeping statements -
1. What is considered gospel truth by the scientific community at large in one decade may be frowned upon in the next. Every study has its critics, & many of the arguments put forth against it are often valid.
2. Fitness professionals /dieticians can often be biased and vouch for one method over another because it's good for business.
3. The media tends to highlight anything that's new & different from the norm. The more different it is from conventional wisdom, the greater the exposure.
4. People are guilty of only reading headlines & not the caveats. So you have notions like the "fat burning heart rate zone" (cardio) or the "after-burn effect" (strength), which in & of themselves aren't necessarily wrong. But often, the context is lost or ignored.
5. Some of the information out there is micro-detail & meant only for professionals/athletes who know what they are doing & want to eke out every single bit of utility possible from a given method. As with anything else, the law of diminishing returns applies. But it is often lost in translation for the average person.
6. Finally, the human body is complex. Add to it individual differences. What works for one individual does not always work for another. There are also many changes going on throughout the life of an individual.
I'm neither arguing for, nor against those who stated that cardio is unnecessary. You have tried & tested different methods, & achieved success. I highly respect that. It's just that I feel newcomers might jump to wrong conclusions when faced with such statements. So it's best to be a bit more conservative. This post is in no way meant to be antagonistic. Rather, it's an attempt to give a more balanced view for the sake of those who may be swayed.
I'll admit I'm probably being a bit over-sensitive. It's probably because of my own experience. Back when I was a kid, I saw an interview of Premchand Dogra where he said something to the effect of 'youngsters these days aren't eating enough chapatis..... so how can one expect to build muscle?' This was the late 80s/early 90s on good ol' Doordarshan, when there wasn't as much information about fitness easily available, unlike today. I heeded his advice & went from being a puny little kid to an overweight little kid, 
. Today, of course, there's all sorts of information out there thanks to the internet. & so this post is probably unnecessary as folks can do their own research. & yet...
Also, personally, cardio has helped me lose weight twice. Once in my teens, without any dieting, (& without any proper information). And again in my 30s, with dieting (& new-found wisdom). (It's a different matter altogether that I have not managed to keep it off though, ).
Though I didn't track my progress in absolute terms on both occasions, I can say with confidence that losing weight in my teens was easier that in my 30s. It's probably fair to say that an individual's body will change over time & consequently, the most effective methods might change as well. Maybe even revisiting some approaches previously discarded could prove beneficial as well. In other words, discarding some method completely could very well prove detrimental. (As it is, every approach has its pros & its cons).
Here's wishing everyone good health & happiness. Cheers!
PS#1 - Apologies for the long post.
PS#2 - [USER=21844]@hotshot05[/USER] You could consider intermittent fasting (popularized by Brad Pilon's 'Eat, Stop, Eat"). But given your ulcer issues, it's best to consult a pro before embarking on a dieting method as different as that.
