I think a lot of guys get wrapped up in consuming too much protein today with the “more is better” mentality. 1-1-1.5 grams per pound of body fat is all anyone truly needs. Layne Norton and Lyle McDonald have hammered the research on this for us.
Using EAA’s to maintain muscle mass while cutting is great as it ensures your body has enough Lucien to ensure the protein you consume is fully utilized.
Others have likely already suggested, but some simple things I would adjust that would make a big impact:
1. Add a good full spectrum digestive enzyme with each meal.
2. Consider switching up the carb sources that could be inflammatory in your gut such as removing processed sugar and maybe the dextrose and using pre-digested forms such as cluster dextrose or Karbolyn. Cream of rice and White Rice would be great food choices as they digest quicker and don’t have the higher fiber content that oatmeal or potatoes will have. I’m a huge fan and believer of fiber intake but knowing your digestive circumstances would just limit and ensure higher water content.
3. Casein: it’s a great slower digesting protein, but is inflammatory for many and can cause GI discomfort. Using a wholefood protein would likely have more benefit or substitute for a clean whey isolate with a high EAA and Lucien content.
Insulin- I know many prefer Novolin R as it’s cheaper and easier to get. But when cutting or in a calorie deficit prefer Humalog as it’s much easier to time and control with its peaks and timing. It may sound simple and old school but I have seen some of the most successful competitors keep it simple and do 6iu humalog pre- workout for 4 weeks then bump to 8iu for 2 weeks then come off. This keeps in line with your body’s natural release and limits insulin resistance while maximizing workout recovery and pump. I’m sure many on here will suggest far more advance protocols, but while simple have never seen that approach not be effective when nutrition and workouts are right.
I have read a lot of your stuff on here and sure you may have considered much of this already so hope it’s helpful!
