Hey and welcome! Not to sound like an old fart, but a lot of us here have been through it all - we've been around the block a few times gaining, losing, regaining, losing, maintaining, etc. There is a lot of valuable information in these boards.
What I'm getting at is, don't be too quick to dismiss the advice to eat more veggies and fruits, etc - we may all "know" that this is what we should do but it's not the only
way to do it.
A lot of us have done the 3 week kickstart and have been either successful or unsuccessful with it and a lot of us haven't gone that route at all. There is A LOT to learn about this whole weight loss thing and there are so many theories and methods that it can take a while to find what is right for you. We are all constantly learning as we go and I know it can be difficult when we are young to understand that although we feel we know so much now, there is yet still so much to learn - hence why these boards are so helpful because you get to hear from so many others' experiences.
For example, A lot of people here have had success with low carb diets. Others are calorie counters. More still might prefer simple portion control. I've just heard of a new one myself - intermittent fasting - I still don't quite understand what it is but it just goes to show you that there are many "right" ways to go about losing weight.
We are here to help you and offer advice that has been coloured from our own experiences and it is up to you to take from that what you will. It just seemed to me that your last post was a little defensive and that might be because you are just starting out and are frustrated with everything but i wish you wouldn't be so quick to dismiss us - I don't think anyone was trying to hint at you being stupid but you did say that you would "not consume anything but water and tea"
and as crazy as it sounds there have been people who have come on these boards saying just that and were actually being literal which can be very alarming.
So i wish you all the strength to carry on with your commitment to getting healthy, ask all the questions and don't worry if you get overwhelmed. Weight loss is a long term project, not a race to the finish line.
btw, you're already on the right track - it takes a lot of courage just to even start all of this and so far you've taken good steps to set yourself up for success. That in itself is something to be proud of!
