@Cana - I enjoy a varied diet, and I was one of those folks who found weight loss easy. In fact, I found it a challenge to halt the weight loss when I skinnied up.
Over my almost 6 years since diagnosis, I've tried all sort of tweaks to my diet - some for improved nutritional content an sometimes from curiosity.
Earlier in the year, I was doing a long-haul flight and fancied fasting through it. The flight itself was only 13 hours, but by the time I added in other factors like airport transitions and the drive at the other end, it was going to be a 24 hour fast. I prepped for that with a few days full carnivore. I was astonished how easy, and how enjoyable it was.
But, to your point, I lost weight doing those days carni (not including the 24+ hour fast), yet my caloric intake was significant.
Were I trying to kick start or restart weight loss, as you are, I'd give it a go for a few days.
Breakfasts, if you want one, are easy - bacon and/or high meat content sausages. Lunches, chicken legs/thighs/drummers/wings, or sausages, or corned beef, of cooked ham, or the like. All very easy to pack up, and can be held in the foil they're wrappedin, if you're not aat home.
Dinner could be chicken (with skin), lamb, pork, steaks, sausages or anything else you fancy.
I'd do it again.
