razvan, ok for your size I think you’ve got some pretty good numbers, and your routine may very well have worked so far, but as you pointed out yourself, progress has stopped.
Since programs are not my strong point (I’m a beginner myself) I would simple suggest taking one of the programs on here, BBB or TBT, and try that out for 6-8 weeks, see if that doesn’t help.
I would also suggest you really clean up your diet. Right now you’re not eating clean, and you’re not eating much either. The oatmeal and eggs are a good start though.
Start following the 7 healthy habits by Berardi, in short, eat every 2-3 hours, with emphasis on protein and veggies. Adjust your meals so that per day you’re eating something like 500 kcal over maintenance. If still no progress (ie. no weight or strength gains in f. example 2 weeks), increase your caloric intake in steps of perhaps 250kcal per day.
Right now you have HUGE gaps (5 hours?) in your day when it comes to food intake, and a really low overall protein intake I’d say. By the way, you don’t mention post workout nutrition? And a cereal in the evening before bed? Come on, your body needs some quality protein for the night to stave off catabolism!
Personally I would suggest limiting carbs to only mornings, and post workout, if you’re looking for a clean bulk.
If you’re looking to grow, the key is never to get hungry, you eat because it’s time to eat, hunger in my book is the precursor to muscle catabolism and even overeating and subsequent fat gains.
Now depending on your metabolism, these suggestions might work, but if you’ve had to work hard to get to your current weight, you might have to eat even more. I suggest keeping a food log for a few days, and try and see where you’re missing out on protein and calories during the day. If your own tweaking with the diet gets you nowhere, post some of your food log on the supp & nutrition forum here, and get proper feedback on it
Again, good numbers for your size, there’s nothing standing in your way of growing some more, except changing up your program, eating more, and staying consistent with it.
