You are fighting millions of years of evolution. If you are in caloric deficit for too long, your body thinks you don’t have food near you anymore and try to conserve whatever energy you have.
Take a diet break and up your calories slightly daily until you see yourself gaining a little bit of weight. Then cut back the last increase.
Keep that calorie intake for a few weeks and then start a new cut after that. Rinse and repeat until you are at your goal weight.
Ab easy rule of thumb is to do a weight cut for 6-12 weeks, and then do a maintenance weight for the same length of time you did your cut.
It’s a decent starting point for a new language. I had to learn webdev as an embedded C coder, and using a LLM and cross-referencing the official documentation makes a new language much more approachable.
