    Cardio in the morning?

    If I do some cardio training in the morning(06:15am)when I wake up and I have not had breakfast yet and then start running 15 minutes on my Orbitrek will i burn my muscle then and be in a catabolic state?

    In my opinion crdio in the morining is to catabolic. You just went 8 or moe hours with out food your body is starving. It will use muscle to fuel itself with. I would prefer to eat a fat and protien meal before I do cardio to aid in fat burning and to stave away catabolism.But it pretty much doesn't matter when cardio is done. Your body doesn't know what time of day it is. Do it when ever, but don't overdo it. Cardio in itself is severely catabolic and will hamper the quest for muscle.

    If I'm cutting I use glutamine before cardio - If I'm not cutting I wouldn't be doing cardio first thing.

    For starters I never asked about whether you were cutting or not. I stand with the statement cardio is severly catabolic. Glutamine really doesn't act like a magic supplement. You really should eat a fat and protein meal even if it is one hard boiled egg. But hey it is your body not mine. Do as you like.

    I agree with you Dorian. I never agreed with cardio on an empty stomach. I did try it before though. When I did, I lost some muscle. Hard boiled eggs are awesome because you can eat them quickly and have them prepared before hand.

    The body, what does it burn for fuel first?

    What are the body's primary fuel sources?


    Lets say I have some bodyfat and muscle. If I go a week without eating anything how does the body fuel itself, it probably burns carbs, protein then fats ? Am i right or wrong?

    In other words it will burn muscle first then when the muscle is gone the fat get burned.But if that situation you spoke of existed. Now during a keto diet the body is trained to burn fat first. This is why I like the idea of eating fat and protein.

    Question Keto diet

    On a ketosis diet can you suffer from heart problems due to all of that cholesterol the fat can give you?

    One thing everyone fails to tell you is that your body will shut down normal cholesterol production as needed. And if this high level is a concern then use some supplements for it. Like niacin and folic acid and flax oils.I have never had a situation where I had high cholesterol on this diet. I guess everyone is different.

    On the contrary, the Ketosis Plan will produce lower cholesterol, blood pressure, heart disease...... Excessive carbs, note, I mentioned excessive, is a direct link to the rise of hypertension, obeseity, elevated cholesterol and a multitude of medical ailments. No I'm not saying that carbs are necessarily bad, they just need to be balanced with protein. I've dieted successfully in the past on carbs, but I found my true success to be the Keto approach.

    It wasn't until 13 years ago when it was suggested that we need to considerably lower our fats (beef, eggs and other quality protein) and increase carbs that the major health conditions arose. The effect was an increase insulin due to the excess carbs and lowered fat/protein. Only a certain amount of insulin can be used at once, the rest will be stored as fat since if it's unused.

    Now different people will definately respond differently to carbs so it is an individual thing. But the fact that low carbs and high fat will increase triglycerides is simply untrue. The fact of the matter is HIGH FAT combined with HIGH CARBS will produce unhealty conditions; you just can't combine the two. Choose one approach or the other and stick with it.

    what you people don't realize is; if your body really does go into your muscles for energy (very doubtful because fat is much more efficient for energy then protien) the worst that could happen is some of the protien stored in the muscle gets taken; but that shouldn't matter because any sane person would eat a good meal after the cardio anyways IE filling up the muscles again so if you eat well ri ght after the cardio it is IMPOSSIBLE to lsoe muscle; i know becuase i jog 30 minutes a day 7x a week

    i get a little confused here. Isn't it that our muscles primary source of energy is glycogen first and then fat? So how could you be using protein as source of energy when there is still fat to burn. Just like the other guy posted, he is big but with lots of fat covering the musles. This case, isn't the early morning cardio the best thing for him?

    If you are trying to burn fat, I believe cardio in the morning on an (almost) empty stomach is a good idea. If you have time for food to digest, eat a banana and a piece of bread with a little juice, then let it digest. If you have no time (like me), you could mix a little bit of grape juice with some carb powder. Failing to let the food digest may result in cramps (which are not fun while running). Both of these ways provide simple sugars to get you going and complex sugars to last awhile before the fat begins to take over.

    Personally, I do cardio in the morning and have not found that it effects my gains. I do drink a protein shake consisting of 24g of protein before I run. And then immediately afterwards I have a protein shake w/ oatmeal and a banana

    During exercise at 25 % V02 max, over 85 percent of energy is derived from peripheral fatty acids (circulating fatty acids from adipose tissue) (Romijn et al. 1993). Other fuels are derived equally from stored lipid droplets, and circulating blood glucose.

    Cortisol is a hormone which is secreted in response to various stressors. In the case of exercise it is dependent on intensity. In a landmark study Davies and Few (1973) investigated the effect of exercise intensity on plasma cortisol secretion during one hour of treadmill walking/running. They found that at low intensity exercise of less than 50 % V02 max, under normal conditions that cortisol levels actually showed a decrease relative to resting levels. They attributed this to either (a) a decrease in secretion rate, or (b) an increase in plasma clearance rate. It appears that during low intensity exercise, that cortisol plasma concentration is therefore dependent on metabolic need. This also appears to be the case during moderate intensity exercise. Sotsky et al. (1989) investigated the effect of hypoglycemia on moderate intensity exercise, below 60 % V02 max over 50 minutes of cycling in participants with normal blood glucose levels of 87 mg / dl, and in participants with low blood glucose levels of 59 mg / dl. No significant difference in cortisol levels were found in the normal glucose condition, while a 400 % increase was found in the low glucose condition. Therefore it appears that under normal dieting conditions that cortisol secretion may not significantly rise during an hour of low intensity exercise, suggesting that it is an effective tool for fat metabolism, without high catabolic effects.

    At approximately 65 % V02 max, fuel is derived from approximately 50 % fats, and 50 % carbohydrates. Of this, fatty acids are derived in nearly equal measure from peripheral and endogenous ( intramuscular) TGs, while the majority ( 80 %) of glucose is derived from intramuscular fuels, with only 20 % from the periphery(Romijn et al. 1993). Of the 20 % glucose released by the liver, approximately 15 % of it is from gluconeogenesis (Ahlborg et al., 1974, Ahlborg and Felig, 1982, ).

    Exercise above 80 percent V02 max obtains approximately 75% of its energy from carbohydrates, of which 80% comes from intramuscular glycogen stores. The remaining 20% are released by the liver. Though the liver provides 20 percent of CHO, only 1% of the total glucose production is from gluconeogenesis. Intramuscular lipid stores provide 7 percent of energy, while peripheral FFA’s provide the remainder of energy (Romijn et al., 1993; Ahlborg et al., 1974)

    Fasted cardio is a myth. Even at lower intensity cardio 60-75 MHR your body still wants to use some carbohydrates instead of purely fat calories.

    If you want to burn the most fat calories without being catabolic. Exercise 2 hours after you eat and at 60-75% of your Maximum heart rate. This way, 50% of the calories you burn will be from your fat cells. So if you exercise for 45minutes at 70%, you will burn about 200calories from fat, and 200 from glycogen stores

    You are in a fat burning state in the morning. Unfortunately, you are also low in amino acids. nTaking a protein suppement or BCAA's can help with this.

    I would take it at least 15 min before the workout.

    Upon waking insulin levels are low, while glucagon is high. Glucagon is higher due to the fact that sugar is low, and the body is beginning to search for stored energy. Glucagon has receptors on fat stores which help to release energy in order to provide energy.

    The body is in a very catabolic state in the morning. Cardio is Catabolic bu nature, its the whole idea. The idea is to burn as much fat as possible while saving as much protein as possible from being used as an energy source.

    What I am sure of is that the body will release more glucagon while blood sugar is low, leading to ketosis (fat burning).

    I am still unsure about whether or not having low blood sugar while performing cardio will actually mean the body will automatically burn MORE FAT.
