The Metabolic Effect Workout

This is the original 20-minute, home-based, do-anywhere Metabolic Effect workout. It was one of the first examples of short-duration, high intensity, dumbbell based metabolic conditioning on the market. Led by Dr. Jade Teta and Jill Coleman of

The Science behind the Metabolic Effect (ME) incorporates the latest understanding in endocrinology, health, fitness, strength and conditioning research. ME is a science-based program focused on changing the fat-burning hormonal response to exercise and diet. By changing hormones, rather than simply eating less or exercising more, the body naturally regulates fat burning, appetite, and mood so that motivation for exercise is enhanced while cravings for food are reduced.

The latest in exercise research says that intensity (how hard you exercise) may be as important, and perhaps more effective, than duration (how long you exercise) (1). This is good news for those who are starved for time. Longer more traditional forms of exercise, like running or jogging, burn calories during exercise, but can negatively impact key hormones responsible for calorie use at rest (2), (7), (8). Smart exercise uses short, focused bouts of exercise focused on weight training and intervals to "turn on" fat burning hormones (3), (4), (15). Research shows these techniques increase fat usage for hours and even days after the activity has stopped and outperform "aerobic zone" exercises like running (5), (6), (9).This is what we refer to as the metabolic "ripple" effect.

This new hormonal approach has other advantages. Traditional forms of exercise, such as moderate intensity aerobic exercise (i.e., jogging, biking, running, or swimming) can negatively alter hunger and stress hormones (10), (11). This leads to increased appetite and cravings for sugary, fatty, and/or salty foods (12), (16). More intelligent exercise using the approaches described above creates positive changes in hormones and naturally regulates food intake (13), (14).

All exercise is not created equal. ME changes the metabolism from the inside out. Change your hormones and the calories take care of themselves.
