Precisely, how did you come to the conclusion that you are 25% Body Fat?
Cutting Body Fat While Maintaining and/or Increasing Muscle Mass
Research by Dr John Ivy and Dr Layne Norton, independent of each other, demonstrated the most effective method of decreasing body fat while maintaining and/or increasing muscle mass is to decrease calorie intake around 20%.
Thus, you 30% would be the most effective. However, based on the research, I’d recommend keeping your calorie deficit around 20%.
Calorie Surplus
Based on the fact that your body fat percentage appears to be relatively high, bulking up and increasing your body fat percentage make no sense.
Thanks for your reply! I just compared myself with a sample picture on the Internet. I also tried US Navy method and the result was consistent with the picture. I’m pretty sure it’s not 15% BF. Even if it’s 20%, I still have to lose BF, right?
This is pretty much the reason why knowing your % doesn’t matter. If you have fat you want rid of it doesn’t matter if you’re 5% or 50%. What matters is how you feel about what’s looking back at you in the mirror. Numbers are arbitrary.
I would personally cut the fat first. Even if it leaves you skinny (which it will) you’ll at least have abs, which is way better in my mind than being fat.
Also, when you’re lean your body just operates better. Things like your insulin sensitivity improves which’ll mean your body is more inclined to add muscle rather than fat.
In my opinion, if you’re already fat then a high calorie bulk is the worst thing you can do.
