im really confused on this...im trying to lose weight but still maintain muscle right, so im eating around 1400 calories per day and im working out for 15-20 minutes per day with another 30-60 min of cardio per day...im also eating around 50 grams of protein per day from food and a shake, im wondering if this is an ok plan for maintaining muscle while still losing fat, because i have heard that undereating will result in your body gettin energy from muscle leading to loss in muscle...
