Diet-wise- If you can eat a big protein meal in the morning, then try and snack on low-fat healthy mini-meals every 2-3 hours, moderate lunch, and then try to another moderate meal for dinner. Basically you want to try and eat your meals like a pyramid- eat more earlier less late and especially try and avoid big fat-laden meals late at night. Alcohol can effect your weight loss as well, it's a huge amount of empty calories that make you gain more weight or prevent you from losing weight more quickly. You want to make your eating as efficient as possible- do not go too long in between meals/snacks. If you do this it can help increase your metabolism and help you lose more weight more efficiently.
If you can try and do your cardio in the morning- it helps jump start your metabolism and makes it more effective as well. If you can't it's not big of deal but get in when you can. If you have access to gym great if not start by walking/jogging on a trail/street/whatever, you can do abs at home as well as push-ups, dips off a chair, body squats and lunges among other things.
If you have access to a gym- talk to a personal trainer- normally gyms give one free orientation so it won't cost you anything.
I was a personal trainer for 5+ years so if you have any more questions or anything else I might be able to help you with just PM me and I'll be glad to help. Don't get discouraged if you don't have instant success, keeping plugging at it, anything is better than nothing so if time is short get something in. Good luck.
