Excessive consumption of branched-chain amino acids (BCAAs) may reduce lifespan, negatively impact mood and lead to weight gain, according to new Australian research on mice.
Does BCAA cause belly fat?
BCAA metabolites were found to be a significant indicator of lean mass in a population of young and middle-aged adults. People who consume a threshold dose of essential amino acids that contain BCAAs with every meal have less visceral belly fat and more muscle mass.
When should I take BCAA for weight loss?
However, people who include sufficient protein-rich foods in their diets most likely do not need to take supplements. The best time to take BCAA supplements is before and/or after your workout.
What are the side effects of BCAA?
It might cause some side effects, such as fatigue and loss of coordination. BCAAs should be used cautiously before or during activities that require motor coordination, such as driving. BCAAs might also cause stomach problems, including nausea, diarrhea, and bloating.
Can you gain weight taking amino acids?
Amino acids have four calories per gram. This is the same amount of calories as glucose, an element of table sugar. However, if you take amino acids as supplements, only small amounts of amino acids are consumed. So they are low in calories, and you are very unlikely to gain weight from them.
Do amino acids cause weight loss?
“Essential amino acids, included as part of a meal replacement, along with whey protein, improved the synthesis of muscle and led to a greater loss of fat,” he says. Both groups lost about 7% of their total body weight.
Do BCAAs speed up metabolism?
BCAA supplementation also improved energy metabolism and lowered levels of substances that indicate muscle damage, such as creatine kinase and lactate dehydrogenase. The researchers concluded that BCAA can improve exercise performance.
Should I take BCAA everyday?
Research has shown supplemental BCAA intake to be safe for healthy adults in doses of 4-20 g per day, with prolonged intake one week or more showing greater benefits than acute (short term) intake. Aim for 2-3 g leucine between meals, before, during or after workouts to maximize muscle protein synthesis.
Why you should not take BCAA?
BCAAs may interfere with blood glucose levels during and after surgery. You may also be at increased risk if you have chronic alcoholism or branched-chain ketoaciduria. Also, avoid using BCAAs if you are pregnant or breastfeeding.
