Tips?

Use a calorie calculator online to determine your TDEE (height, weight, age, activity level, etc). Then eat 80% of those calories. (i.e. 2000 cal TDEE x 80% = 1600 calories).

Count calories. Write them down, use a spreadsheet, remember in your head, etc. Track your calories because if you don't you'll most likely overeat.

You don't need to exercise to lose weight, but it definitely helps. 2-3 times a week is doable for most people. Do some weight lifting as well to build a little muscle. You won't turn into Arnold by lifting 2-3 times a week at a moderate level which is what a lot of girls worry about.

Try to simply eat healthier stuff overall. Extremes are generally not sustainable. Continue eating the foods you like, but make smart subtitutions. For example, at Wendys get a grilled chicken sandwich and baked potato rather than a burger with everything and small fries. Don't be afraid of fats like nuts, avocado, etc. They keep you full longer.

I also cut out liquid calories as much as possible. No pop, minimal juice, limited alcohol intake, etc.

Finally, I still eat junk food sometimes and have treats like ice cream and cake. Unless you're entering a bodybuilding contest, you can afford to treat yourself now and then. If youre still eating the foods you enjoy, it wont feel like a diet or cutting back as much.

That's what has worked for me over the years. Good luck!

My best tip: accept that losing weight takes time.

Make changes to your eating and moving habits that you can sustain.
Keep doing these things for the long term (monitor and adapt as needed over time) and you will lose weight.
