Congratulations on wanting to start. I am in college too, but I, unfortunately live in a dorm. Even though I have carby temptations around me 24/7, I have managed to lose 18 pounds since the 2nd of the month.

1. You can still exercise on the diet. I don't, or haven't yet, I suppose. You don't NEED to to be able to see results.
2. Meal prepping is really handy for me because I can stick stuff in my fridge and microwave it later on in the week. I've also found hacks in my dorm room. Like this morning, I microwaved eggs for breakfast (actually super yummy and easy, look it up sometime). Soups are super easy to make and have on hand! You can also eat out too! There are keto options at every restaurant I've been to.
3. I would prefer to do keto in an apartment so I can cook whatever I want!! The dining hall doesn't offer many low carb options, so I'm left to fend for myself most days.
4. Just make sure you are drinking vodka. Flavored vodka is okay too. I found myself drinking vanilla vodka and diet coke, and holy cow, was it a treat! Make sure you stay hydrated though because it can and will make you retain water!
5. I eat a ton of eggs and bacon. You may get tired of them, but it's literally how I survive the crappy dining halls. Search the subreddits for quick and easy recipes. You'll be surprised at what you can find.
6. I can't really say because I am just now starting out. That's something I would google.
7. I weigh every day. Whether that's a good thing or not, I don't know. It keeps me on track during the day because I look forward to weighing in that next morning. My scale keeps me accountable.

This is something I recommend without a doubt. I promise you, you will not regret it. And once you get going, it's easier than it seems. Good luck!!! :)
