If you're just getting started on your weight loss journey, here's a quick workout you can do to build your starting strength and lose weight while building muscle.
10x pushups (do them on your knees if you can't do fully extended pushups)
10x squats (make sure to go down until your thighs are parallel to the ground)
10x lunges (step forward with your hands on your hips until your knee touches the ground)
30x jumping jacks (to get your heart rate up)
20 second plank
Now take a breather, take a sip of water, and start it over again! If you find at any time the workout becomes too easy, you can increase the number of repetitions or replace push-ups with burpees and squats with jumping squats.
That's all for now!
