Need guides and tips.
I would say start with walking everyday or every other day. You have to start somewhere. Plus, when you're out of shape you can't just start out with the extreme unless you want to hurt yourself, so start out ready and work your way up. The hardest part is always the beginning and then it gets easy with hard work and consistency. Hope that helps! :-)
You can also start logging your diet and activity with the myfitnesspal app. You'll get in the habit of thinking about good food choices and be motivated to fit in little exercises (2 minutes of jumping jacks, 15 of walking, etc. ) here and there to start chipping away at your calories...
Find little light/moderate workouts here and just give em a shot.take it slow at first.
Most of your fitness goal effort needs to be in what you eat, whole foods, fruits veggies whole grains, avoid sugar as much as you can also processed wheat products, liquid calories (juices, mixed coffee beverages, soda) i find if I'm gonna cheat i should do it later in the day because those things cause intense crashes/cravings which are better faced while sleeping so i can just reset when wake up and not keep eating more.
Good luck! There's no great trick to it, with a little effort, lots of attention to your body and how you feel after certain foods and exercises, some checking in with friends on the forums, and honest tracking, if you just stick with it, through the setbacks and plateaus and everything, your gonna get there, guaranteed.
