It's A Lot Of Prep Work But This Guide's Tips Will Get You "Vegetarian", "Invincible", "Paleo Diet", And "Under The Stars" In One Playthrough.
Prep Work
---------------------
Bring 50 Jerky And 5 Jars In Your Dog's Bag And Hang Around, Barely Going Downriver, For The First 20 Days. This Will Get You Vegetarian.
And Paleo Diet Will Be Easy To Get Afterwards If You Just Start Playing "Normally".
Don't Go Too Far Downriver, In Addition To The Dangers Of The World, The Game Gets Colder. If You Can't Keep Your Body Heat Up, You'll Need Clothes, And You Can't Kill Anything To Make Them For The First 20 Days.
You Lose 1000 Hunger In The First 20 Days, Afterwards Start Hunting Rabbits/Wolves/Etc.
- 10 Cooked Meat Should Get You Close To Paleo.
You Lose About 50 Hunger, ~65 Thirst, And ~65 Fatigue A Day. So Plan Accordingly
Pro Tips And Helpful Hints
------------------
Catch Rain Water With Your Jar/Jars.
Wow, It's Not Listed In The Effects But Each Drink From a Jar Gives You 1 Hunger.
- So Standing In The Rain Constantly Spamming Drink/Refill Will Get You About 5-10 Hunger Back For Free Each Rain Storm.
Definitely Don't Sleep Through Day Changes. Even Sleeping Through One Daybreak Makes Your Playthrough An Entire Day Longer.
- However Sleeping 8-16 Hours A Day (Or More) Does Save You About 5 Hunger And Thirst. This Compounds Over The Course Of 20-40 Days To Save You A Few Jerky.
No Animals Can Die While You Play The FIrst 20 Days.
- Apparently The Game Saves When You Land On An Island, So If You Hear Something Kill Something Else (Like A Snake Killing A Boar) And Are Worried About It, Alt+F4. This "Should" Load You Back To When You Landed And You Can Just Leave To Go To Another Spot Before It Happens.
- Can't Confirm, I Didn't Have To Try This.
Let's Start The Playthrough
-------------------------------
Day 1
--First Lucky Camp--
- The Camp I Found Had 1 Old Lumber, 14 Cat Tails, And a Flint. I Made A Campfire At The Entrance, (Right As You Step Off The Dock) So When The Game Spawned Wolves I Didn't Have To Worry About Them.
- I Used The Rest Of The Cat Tails For Tinder To Relight The Fire After Each Rain. If The Campfire Sleeping Either Reset Or Got Rid Of The Wolves, I Ran To The House That Was There And Slept There To Pass Time And Save Tinder.
- If Sleeping At The House Spawned Wolves Again, I Ran To The Entrance Fire I Built, And Waited For Another Rain, Then Relit The Fire.
A Fishing Shack (Bait Shop) Is Your Best Friend Here, In Lieu Of A Great Cattail Start.
- Wolves Rarely Spawn At Them, Allowing You To Pass A Lot Of Time In Between Rains.
Spamming Jar "Use" And "Consume"
Rain Water Chugging - Really, Really Helped. I Was On Day 20 And I Had Only Used 27/50 Jerky.
Day 20
The Vegetarian Achievement Is Yours! If You Haven't Unlocked The "Invincible" Achievement Yet, It Unlocked At The Same Time. Even Though My Gauges Weren't All At 100%.
I Still Had 23 Jerky Left, So I Went For Paleo Diet. Still Haven't Left The First Camp I Stopped At.
-------------------------------
Day 23
Once I Started Traveling, I Started Looking For 2 Things; Cat Tails And Saplings.
- Once I Had Enough For Snares And Spike Traps, I Killed Some Stuff And Cooked The Meats.
Day 32, Traveled 7.1 Miles Total
Heading Downriver A Bit, Hunted 4 Rabbits, Spear Trapped Two Boars And A Wolf.
- Also Found A Bear Attacking 3 Wolves And Stole The Spoils Once The Bear Went Back To It's Cave.
- 15 Jerky Left, Still Chuggin Rainwater, Still Sleeping Through 2/3 Of Every Day At Fishing Shacks And Buses.
Day 40
Paleo Diet Achieved. And Can Confirm "Under The Stars" Is Linked To Paleo Diet, Got Both On Day 40, And I Definitely Slept In Shelters Multiple Times.
Good Luck!
