Do you know of any good workouts you can do around the house without
weights and machines? Also, is lifting weights just as important as cardio
during the weight loss procedure?
You can look into workouts like p90x or insanity. I believe they are based around at home routines that you can do without weights. I believe this is a type of workout that implements common weight training exercises like push ups and sit ups but at a very fast pace so it becomes a cardio workout at the same time. This burns a ton of calories and thus leading to fat loss. You can most likely find free routines by searching around the internet.
I honestly believe that weight training is MORE important than cardio when it comes to weight loss because weight training stimulates muscle growth which will prevent the breakdown of muscle tissue while in a caloric deficit. If muscle is lost your metabolic rates goes down and therefore you burn less calories naturally which is not a good thing. However if you are eating enough protein ( see my other posts about my beliefs of protein consumption ) and stimulating muscle through physical work or at home workouts this will most likely lessen the impact of muscle loss.
