Rapid weight loss costs you muscle and bone. When you lose weight fast, 25-40% is lean muscle, which tanks your metabolism. Losing more than 14% of body weight in three months risks serious bone loss and hip fractures later.
All women should know that the average weight loss is actually 25 to 40% of that weight loss is lean muscle mass.
So you're not losing fat, you're losing your muscle, which is necessary for—
High metabolic rate to break down your calories at rest. And that is unless you prioritize two things, protein and strength training. And the other loss that you get that I don't think I've heard talked about much is that if a woman's losing weight rapidly, so over 14% in 3 months or so, you'll get rapid bone loss. So you don't want to shoot yourself in the foot by not only losing muscle but then losing bone. And, you know, hip fractures are a huge source for what we call bad outcomes when it comes to end of life.
