My best weight loss tip is to stop eating sugar and stop drinking alcohol. For me, this always brings my weight down quickly. Of course it is much easier said than done:)
Walking is great exercise. That and bodyweight exercises can be done without a gym. I suggest moderate exercise, get plenty of sleep, and eat healthy meals every day. Eating healthy meals, staying hydrated, and resting well will help curb cravings for junk food.
And if you are stressed then practice some stress management. Stress can make it hard to lose weight.
Hope this helps. Good luck with your goals. Stay focused and be patient and you will reach your goals.
