Weight loss is not about the exercise you do. Exercising helps the process, and yoga has excellent benefits like improved flexibility, relaxation, and balance, but it isn't a big calorie burner.
Because losing weight is more about the food you eat, you can lose weight doing any activity. Focus on the kitchen, and track your yoga, but realize that yoga does not replace regular cardio nor strength training. It's a great supplement to them both, though!
As for Bikram yoga, I do not trust the estimates claimed by its practitioners. Sweat is not an indicator of increased calorie burn, nor even effort: It's a sign of your heart working harder to cool your body. Exercise calories are burned through muscle movement; this is why strength training's calorie burning benefits are indirect. You don't burn a lot of calories lifting weight, and Bikram yoga is no different. There is no evidence that you burn any extra calories doing Bikram yoga over regular yoga (it's literally the same moves, just in a hotter room.) You can't trust heart rate monitors for estimates doing it because heat causes your heart to beat faster... but not necessarily your muscles to work harder.
If that were so, the southern US wouldn't be the fattest area in the country. We're ALWAYS sweating down here. ;)

Writer, mother, wife, and breadwinner. I love to run, but running doesn't love me, so I'm switching to my low-impact bike.
