Does exercise burn glycogen or fat?
Your muscles first burn through stored glycogen for energy. “After about 30 to 60 minutes of aerobic exercise, your body starts burning mainly fat,” says Dr. Burguera. (If you’re exercising moderately, this takes about an hour.)
What Burns first glycogen or fat?
The body burns sugars first. Low glycogen levels (stored carbohydrates) combined with high-intensity exercise creates opportunities for the body to burn higher amounts of muscle—not what anyone wants.
Does cardio deplete glycogen?
Doing cardio will slowly (keyword: SLOWLY) deplete your muscle and liver glycogen stores. This is nice, because if your glycogen stores get too high, they will “spillover” and become body fat and even form dangerous compounds like VLDL that can cause heart disease.
How much cardio does it take to burn glycogen?
To give you a rule of thumb: after approximately 80 minutes of exercise at a maximum lactate steady state, glycogen stores are depleted.
Does HIIT burn fat or glycogen?
To power your HIIT session, your body taps into muscle glycogen, not your fat stores. This might sound like the opposite of what you’re after, but its weightloss powers are more subtle: “HIIT triggers a release of human growth hormone and testosterone, both of which play a key role in metabolising fat,” says Sigrist.
Can you burn fat with full glycogen?
That energy either comes from glucose (made from carbs) — which can be used immediately or stored in the body as glycogen — or from fat. Yes! You’re constantly burning a mixture of carbs and fat, but you burn more or less of them depending on what you’re doing.
Can fat be turned into glycogen?
The Bottom Line. Your body cannot convert fats directly into muscle-ready glycogen. However, through a series of metabolic processes that result from conditions of depleted carbohydrates, it is possible for stored fats to be broken down into glucose, which can then be converted into glycogen.
Why does running slower burn more fat?
By slowing down, your body will get better at generating energy from fat and over time, you’ll be able to run faster ( and burn more calories) while maintaining the percentage of energy coming from fat.
How do I train my body to burn fat instead of sugar?

Does cardio burn fat?
The research from over five studies suggests that cardio burns fat through calorie expenditure and is mainly excreted through gases via the lungs. The most effective way to burn fat is through a mix of high-intensity interval training (HIIT) and weight training.
Do you burn more fat doing cardio or weights?
A cardio workout burns more calories than a weight-training workout. However, your metabolism may stay elevated for longer after weights than cardio, and weight lifting is better for building muscle. Thus, the ideal exercise program for improving body composition and health includes cardio and weights.
Should I do cardio before or after workout for weight loss?
The majority of fitness experts will advise you to do the cardio after the weight training, because if you do cardio first, it uses up much of the energy source for your anaerobic work (strength training) and fatigues the muscles before their most strenuous activity.
What happens if you don’t replenish glycogen?
Muscle glycogen is the predominant fuel source used during long bouts of aerobic exercise. In fact, aerobic performance is directly related to initial glycogen stores. Once glycogen is depleted, the athlete will feel fatigued and performance will suffer.
Does weight lifting deplete glycogen?
Previous resistance training research suggests that weight training is associated with a consequential depletion of muscle glycogen stores.
How do you know if your glycogen stores are full?
A glycogen rich muscle often holds water, giving it a feeling of fullness and size (which can be a subjective measure nonetheless). If you are experiencing a feeling of flatness or depleted muscles (yes, as crazy as this sounds), it may be due to glycogen depletion.
