How to Lose Weight Even After Menopause

Recommended Answer:

If you weigh 180lbs, eat 180grams of protein. That's it, don't listen to the bogus take this and that so you won't lose muscle. It's simple, if you weigh X then eat X grams of protein.

Other Answers:

• Simple. Take a BCAA ( branch chained amino acid) it is essential for keeping muscle while loosing fat. It allows you to keep muscle during your cutting period ( caloric deficits). If your body has more calories then it uses everyday then you body is more able to gain muscle and put on weight, the same goes for when your body is burning all the calories you take in and more, your body will go to your stored fat as an energy source. During your cutting period, you will loose a small amount of muscle that cannot be avoided. The same goes for gaining muscle without some amount of fat. So just get a BCAA and be sure to eat lean proteins. Good luck.
