Yeah, don't quit eating, that's no fun.
Welcome to the forum! Poke around, and see if any of the boards interest you. Then, hunker down and start making friends!
My recommendation: choose one goal to focus on a month. The benefit of this strategy means you give yourself permission to focus on one thing at a time. At the end of the month, you've 'mastered' (at least in theory) that habit, and you're ready for the next one!
These are cumulative, so you're ADDING one after the other. This kind of layering seems slow in the moment, but can be very effective long term; in six months, you could be more comfortable on your feet and eating more vegetables & protein, which would in turn help you focus on good nutrition and healthy movement! The fat loss that comes as result will just be a nice bonus.
Eg.
Month 1: Eat at least 3 full serving of vegetables a day. Veggies are great - chock full of nutrients, water, fiber, etc. Plus, they help keep you full. I've found that I do better when I can focus on doing something (ie. eating vegetables) rather than NOT doing something (ie. ignoring that donut).
Month 2: Make sure you are eating at least 0.8g of protein per kg of bodyweight every day - for fat loss, aiming as high as 1-2g/kg can be even better for satiety and preserving muscle when you start losing weight. Prioritizing protein does (at least) two things: makes you take a closer look at what's in your food, and helps fill you up with the good stuff so you're too full to eat less nutritious foods.
Month 3: Walk for at least an hour a day - this can be split up into 30min, 20min, or even 10min chunks! Just get walking. Walking is awesome.
Month 4: Brush & floss every day (yeah, I know, not diet related, but we all need a break! plus, gum health is directly related to risk of cardiovascular disease)
Month 5: Limit high carbohydrate options to 3 servings a day - so, potatoes, bread, anything with sugar, etc. One at each meal (or 2 at dinner, none at lunch, etc) doesn't restrict your options too much, but it does make you really choose what you need and what you can sub out with other options. Greek yogurt, cottage cheese, carrot sticks, cherry tomatoes, apple with peanut butter, beef jerky, etc. are all awesome snack options to try.
Month 6: Eat at least 5 veg a day. Level up from Month 1 - lets you tweak & add to previous success, as well as gives you the opportunity to focus on long-term meal planning & eating habits that will last you a lifetime.
Most important though: Have FUN and Be SAFE!
'Hope to see you around!
