Well.. you can increase it slowly, yeah. But if you haven't been seeing the results you want, it's only a 200-300 calorie jump from 2300 - 2600 right? So I would do it over maybe 10-14 days if you can.
You can keep the carbs at 250g on workout days then - sorry for throwing so many numbers at you, but with all the posts I do it's hard to remember exact numbers I have given people all the time haha.
But yeah, aside from that, work on hitting those numbers over the next week or so 😊
Haha no problem, I don't expect you to remember all of the advise you've given me! Anyway, you said earlier that you'd give me some suggestions on what to eat to help get some extra calories. I already eat coconut oil, nuts, peanut butter, and avocados. I like these because they're all really calorie-dense so I can eat a small amount of them and still get a good number of calories. Any other calorie-dense foods you can suggest?
