First of all, welcome!!! And good luck!!!
Most people suggest one change at a time, like cutting out sugary drinks, or upping your veggie count. IanG would actually be a really good person to talk to about food. I find women's and men's bodies tend to behave a little differently when it comes to food and weight loss, but that could just be my personal experience and not the norm.
You could try making changes to thin crust pizzas that are veggie loaded, or getting more water in you. I don't think less carbs always equals healthier... I think its more about which carbs. But I personally go by calorie counting and just having appropriate portion sizes. I don't eliminate anything, just have it in moderation and if I have a bad day, I don't let it become a bad week by repeating bad mistakes.
I have no idea what T25 is, sorry
