I enjoy playing the starvation strategy

. I haven't played with the expansion, so I can only comment on regular 2, 3, and 4 player games, and I like 4p games the best. I never use starvation in 2 player games because it is really inferior, and will usually lose. It is much stronger in 4 player games.
The optimal starting position is 3rd, because after the first player takes the agriculture spot, and the second player takes the tool spot, then the third player can take the meeple hut without tipping anyone off about the strategy. Then second turn getting the meeple hut is likely again, then third turn you can take meeple hut a third time and it shows what you are doing, but with 8 meeple you are fine if they start blocking now.
Third starting position is also strong because the game is likely to end in 11 rounds, giving you the first choice in the last round which can be a game winner.
Trying to starve while starting in any other position is not as good. If you are the first player, starving will almost certainly fail, as it's unlikely you will multiply meeple very fast.
If two players try to use starvation, they will probably both lose to the other 2 players. It's only a good strategy if a single player is using it. If 2 players are doing it, and one is in front of the other, the second one should abandon this strategy right away.
If someone is using starvation, besides blocking the meeple hut, don't let them get the building and meeple multiplier cards for points.
When all 4 players get an item, and the last couple choices are agriculture or tool, take the tool. The tool is nearly as good for you and the agriculture is completely worthless to them.
At about round 9 or 10, blocking the meeple hut (or just taking it) is not a very strong play, so forget about blocking it by then unless you think that player is winning and is strong in meeple multiplier cards.
In the early rounds, the starver is using 2 meeple on the meeple hut, so they are getting fewer other items than other players. In the later rounds they are getting more items than anyone else. Each round the game continues is good for a starver, so if you let the game go 14 rounds the starver will win. If the game ends early, the starver is way behind, so you could focus on one building stack and make sure the game ends sooner.
Even if you are not planning to starve, if you need to gain 5 food to feed your meeple on any turn, consider using your meeple somewhere else instead of gaining those 5 food. Because that's 10 dice pips of food which is equal to 10 points. You are using your meeple but not improving your future position.
This can be a very fun strategy indeed. I once grabbed all 7 spaces of wood first play for 3 rounds in a row mid to late game. Needless to say, I didn't need 25+ wood, but wood was needed for every building that was showing, and cornering the market on buildings was a lot of fun. When I hogged the wood the second time, I didn't buy any buildings because I knew I could block wood again since I would be first player the next round. I did eventually get to use all that wood. What made it even more fun was all the other players commenting that I clearly didn't know how to play, and I was making bad decisions, and then won by a huge margin.
That is when starving goes well, but it can be blocked and it loses regularly too. If I am first player, I am almost assuredly going to take agriculture, because it's a better choice than trying to starve.
