Would working out 30 minutes a day help with weight loss or only to maintain?

Along with a healthy diet, definitely helps with weight loss

Every bit helps ..

That and eating better and the right foods and have to avoid carbohydrates

It totally depends on what the exercise & the intensity level is & what your current fitness level is. Also no point in "working out" if your reward is to eat poorly later.

Yes but try to watch what you eat. Eat healthy but eat healthy foods that you enjoy

Anything that builds your metabolism will help with weight loss. Treadmill, stair climber, fast walking..

i think so, but much of it is your diet too and how much you eat.

That and your diet.

Depends what you’re eating

Waste of time tbh, you smoke?

Yes it would definitely help with weight loss, but you also need to keep an eye on your diet though. Otherwise you could actually gain weight.
