<human>: Can you condense the text into a few key points?

Hi everyone. I'm a short term lurker who decided enough was enough, made an account and created a plan. However, I have some concerns about starting.

Quick details: Early 20's college student, 5'7" and just recently crossed 200lbs. I began college 4 years ago at 155, the healthiest I had been and my goal weight. I've decided it's now time for a lifestyle change. My concerns are basically that I feel like my decided changes are large and going to be difficult, but I still feel like they may not be enough.

The biggest changes are:

Moving from eating out from 5-6 times a week to 1-2 times. This frequency is because the only time my significant other and I get to see each other throughout the day is during lunch and we usually go around campus for something between classes.

Cutting soda consumption to strictly only when I eat out. Soda is my biggest vice, especially when stressed. I've begun cutting it out by switching to less sugary alternatives and more water.

Cutting back on red meats/pasta. My dad's side of the family has a history of slight cholesterol issues, and I'm a damn picky eater. I'm trying to adjust myself to a more broad general diet before I force myself to eat better.

Exercise 3-4 times a week. Just started C25K as well as walking to class instead of driving. My car is dying and eventually I plan on buying a bike (when I have extra funds) to get to work and around town.

Despite the fact that I feel like these changes are going to be hard, I feel like I still need to do more to be "correct". Will I be fine starting off on this scale before trying to change a little more down the road when I've adjusted or to make the big switch now?

(Also, I read in the FAQ about a Day 1 thread that I haven't seen recently at all? So I decided to make this post)
<bot>: had enough, but am worried about not changing enough while also being worried about changing too much at once and not being able to handle it.
