You've changed your diet. You workout using an integrated training program. Your body is constantly being challenged, but your results are starting to slow down. This is common and normal. Accelerated fat loss is not going to be a common occurrence throughout your entire fitness program. Some people can accept this and move ahead with patience. Most people want instant gratification. If they are not continually seeing positive and constant results, their motivation waivers. Sometimes, you may consider supplementation during certain periods of your training program. Pyruvate is one of those supplements that can kick it up a notch for you.
Pyruvate was discovered as a fat loss aid by researchers at the University of Pittsburgh. When looking for compounds to improve the lipid profiles of obese subjects, researchers found that pyruvate had a positive effect on health, increased fat loss and decreased the amount of lean body mass lost.
In a six week, placebo-controlled, double-blind study (Kalman et al, 1998), researchers found that the supplemented subjects participating in a three day/week aerobic/anaerobic exercise program lost 5.5 pounds of body fat and 2.8 pounds of body weight compared to no changes in the placebo group. Thus with no changes in the placebo group following the same program, the changes in the pyruvate group were attributed to the 6 g/day of pyruvate.
Pyruvate is a buffered (typically with calcium) form of pyruvic acid that is created in the body during the metabolism of carbohydrates and protein. It is also found in several foods such as, red apples, cheese, dark beer and red wine.
Animal studies found that pyruvate supplementation leads to weight loss by increasing the resting metabolic rate. A few clinical trails also indicated that pyruvate supplements may improve exercise endurance, though no increases in strength were found. New research is being conducted on how pyruvate functions as an antioxidant, inhibiting the production of free radicals. Because of these antioxidant properties, pyruvate may inhibit the growth of cancerous tumors.
By eating a balanced diet in addition to working out regularly, you can speed things up by adding 3-6g /day of pyruvate to your program.
