But how sensible is it to hit these marks? How a lot weight are you able to lose in per week? A month? Six months? And extra importantly, how a lot weight are you able to safely lose in a sure period of time?
The unhealthy information: You can’t actually predict precisely how a lot weight you’ll lose in a sure time — there are simply too many variables, says Jaime Schehr, R.D. and naturopathic doctor based mostly in New York.
Workout stage, workout style, muscle mass, macronutrient consumption, sleep high quality, stress ranges, gender, genetics, medicines, and alcohol consumption all come into play and affect how a lot fats your physique will each burn and maintain onto.

There is a well-established components to find out your RMR based mostly on age, top, weight, and gender, says Robert Ziltzer, M.D., an weight problems medication doctor at Scottsdale Weight Loss Center in Arizona. Most on-line calculators use this components, making them surprisingly correct, he says.
