Energy balance

Weight loss via calorie restriction alone, without resistance training, leads to a loss of appendicular lean mass and an increased prevalence of sarcopenia in breast cancer survivors.

If you lose weight through diet alone, you risk losing muscle mass, which can lead to sarcopenia. To preserve muscle, combine calorie restriction with resistance training.

Of note, both diets also resulted in reduced appendicular lean mass and a significant increase in the prevalence of sarcopenia (10%, P = 0.04).
