Protein and Calories
My mom has started a new diet. She's eating under 2000 calories (which is way too little for her size and activity), but believes it's fine because she's still getting enough protein. Her main goal is to lose weight. I'm worried she'll lose weight + muscle, but she says she won't lose muscle because she's getting enough protein and exercise. I still don't think this is healthy. Some days she even eats under 1000 calories. She doesn't even use olive oil or seasonings to cook anymore. Just boils chicken and broccoli. When I asked her how long she'll do this, she says until she's 180lb (she's 230lb). I don't know how quickly or slowly she'll get to her goal. Is this safe long term?
