It is easier if you gain more muscle mass, you automatically start to burn more calories, even when resting. Also your numbers are off. 1000 calories is easily obtainable within one training. A kickboxing lesson at my gym takes 1.5 hour in that time I already burn 1000 calories [1]. Personally I find it sufficient to introduce more protein to lose weight in my diet, but I never had real problems with my weight in the first place. [1] https://www.urmc.rochester.edu...

Python and java are good generalists, but a bit boring. Personally I like functional programming better, but that is because I work on distributed systems. If I wrote device drivers I probably loved C. Programming languages are just tools in the end. I think such a popularity metric is useless to measure how good a language is. E.g. if we go down that path we could deduct that TCL is superior for hardware design, because it is used there often. Well, that doesn't make sense. What does make sense though, is that TCL is very small, easy to embed and extensible. So it is a good choice to embed in your product. I like TCL btw, it is a weird language, it has something lispy to it and it has simple rules, which allows you to reason over the code you wrote.
