Are you referring to a specific plan written for you specifically, meaning your goals, weight, macronutrient breakdown, and training regimen? That would require writing your own diet or paying someone to do it for you.
I believe this right here is what has caused your so-called "damage". The more one yo-yo's in intake, and respectfully, in weight, the less efficient the body becomes with caloric intake. This is the reason why a person who has not yo-yo'ed can maintain or reach a desired body composition at a higher caloric amount than someone with similar stats who has yo-yo'ed in the past.
This is why it's wise to never get too fat in the first place.
Are you REALLY inclined to get fat with 2000 kcal per day at 27 years old, 6', and 191 pounds with a decent amount of physical activity?!
Of course I do not know, but I strongly believe you are not counting your macros and calories correctly. For my first bodybuilding show, I consumed 1950 to 2150 calories for the last month and I was out of my damn mind! Actually, I was starting to "lose it" when I got into the low 180's and I am not even a hulking tall guy.
Please, if you can, show us a day's menu providing 2000 kcal with exact foods and measurements?
And what do you mean by fat? Can you please post a picture of you as a lifter, at 6 feet and 191 pounds who's been lifting for a year and a half with a decent program of the basics?
I think your discomfort might be uncalled for, but who am I to tell you what body composition you are comfortable with? Seriously, 191 as a lifter at 6 foot and feel sloppy with a shirt off, dude? If you have a decent amount of muscle, then you might actually be shredded just by losing ten to fifteen pounds, which is not much.
In short, I think you're a bit "off" on some things, with both your diet and view on your own bodily image.
Provide pic and menu.
