If you want to go hardcore, you could try limiting your vegetables etc. to things with very high fat content relative to protein and carbs—avocado, macadamia nuts, olives, heavy cream, butter, and olive oil. This would give you a break from insulin-related metabolism, which has different benefits than the low-methionine state that might be synergistic (because in both cases anabolism is limited. I’d guess that people who rarely or never do anything like actual fasting or keto would benefit from this modification.
This list of foods by methionine content (haven’t checked its accuracy) might be helpful.
