Does doing cardio make you lose muscle???
Unlike resistance (weight) training, cardio exercise is traditionally based around repetitive bodyweight movements which maintain a medium to high heart rate for extended periods of time. What this means is that your body’s energy output is more centered around entering a catabolic state (tissue burning) rather than the anabolic state we need to build muscle.
To put really simply, when doing cardio exercise, energy is burnt in this order;
1) Carbohydrates (both stored and direct from foods)
2) Fats (from foods and as stored cells)
3) Proteins (amino acids from muscle tissue)
Points 1 & 2 above are where you should aim to be and aim to stay. It is at those stages where one can rapidly reduce their body fat levels while maintaining their hard earned muscle mass. It is point 3 above that causes all the headaches! This is where your body transfers into a state of mass catabolism just to maintain energy output levels. It has burnt through the energy assigned for standard exercise and now needs an external outlet to keep the ball rolling. The body begins to feed off its own muscle cells as a key source of energy. Typically when we start to DIET we do 2 things increase our cardio and decrease our calories. What this does is create a deficiency in carbs and our body does not want to let go of the fat cells so the next thing would be protein (muscle). How do we stop this from happening??? Well by eating yes eating 1-2 large servings of complex carbohydrates, you are ensuring your first choice energy stores are at full capacity, the higher they are, the longer they will last. You may ask how do I lose weight if I eat??? Our goal is to increase muscle density and jump start our metabolism. The way we do this is by increasing our resistance and cardio training and by feeding the body. Once our body understands that more energy is needed and it has a source of fuel (carbs) then it will speed up the process and let go of the fat cells. If our body thinks we are starving it (decrease calories) then it will go into survival mode and fight to keep those fat cells. The only other thing that is left to burn then is muscle and the body would rather burn protein (muscle) rather than fat in the survival mode. Cardio does not build muscle mass like resistance training and we need muscle mass to keep our bones healthy and fight the challenges of aging. Resistance training does increase heart rate as good as cardio so we need cardio to burn fat and help speed up our metabolism. Together resistance, cardio training and eating are necessary for losing fat and feeling great.
Next time I will talk about how much to eat and when to eat……
