Dr. Sims explains that 1,100 to 1,200 calories is roughly an average resting metabolic rate, the energy you need lying in bed. When you eat that little, the body perceives a threat, conserves energy and breaks down lean mass. Women often see more belly fat, puffiness, poor sleep and no response to training.
Dr. Brighten says it is not hot flashes or irregular periods. Progesterone is the first hormone to decline, so worsening PMS, irritability, breast tenderness and waking at night or very early in the days before your period can be the earliest signs, sometimes from age 35.
No. Nikkiey explains that protein sources differ in essential amino acids and bioavailability. Animal proteins are complete, many plant proteins are incomplete, and whole foods like chicken and meat also carry vitamins and minerals that processed protein powders and bars don't.
Nikkiey explains that toned isn't produced by weight loss; it comes from having enough muscle under a reduced layer of body fat. The medication suppresses appetite and creates a deficit, but without a muscle-preserving strategy you can lose muscle along with fat and end up with a smaller, softer body.
