Fatloss is the biggest source of misconceptions concerning strength training. And the number one misconception and false statement made about strength training in regards to fat loss is that strength training is the key to fatloss. Fatloss and strength training bloggers alike get droves of people to their sites by telling them what the KEY to fatloss is. But strength training is not it.
You can strength train your butt off for years, becoming incredibly "strong" and still have your gut proceed you into every room. Anyone who has been both strength training for a while and who has problems with body fat will tell you that strength training will not magically melt pounds off your body because of all the "fat burning muscle".
Yet, people are still hearing things like:
"A pound of muscle burns thirty calories a day!"
Not true. A pound of muscle burns maybe 6 calories just by virtue of its existence.
"Strength training stokes up your metabolism and turns it into a roaring furnace!"
BS. This myth probably stems from a phenomenon called EPOC (Excess Post-exercise Oxygen Consumption). EPOC is one of the processes involved in recovering from high intensity exercise like strength training. During this process, oxygen is consumed at a greater rate for a certain time after exercise while the system returns to homeostasis. This means that a greater percentage of fat is burned during this period.
EPOC is the claim to fame for HIIT (high intensity interval training) versus steady state cardio. However, the effect is easily overestimated and widely overindulged by "fatloss experts" who want to re-invent the exercise wheel because they are too lazy or simply unqualified to do what needs to be done FIRST. What is the first thing? The first order of business is to help people get their diet in line and to change their eating (lifestyle) habits. Movement is a big part of fatloss and a big part of health. But EPOC won't make up for a bad diet. And it won't erase the effects of sitting around 23 hours a day.
One role that exercise has in fatloss, and especially strength training, is the preservation of lean muscle mass. Preserving lean mass while losing fat can be very important. Another very important factor that exercise seems to play a key role in is controlling visceral fat.
The different kinds of fat in our body are basically named by where they are located. So visceral fat refers to the fat surrounding our organs. Even very thin people can have a problem with visceral fat and lack of exercise does seem to be a primary factor. You can have very low subcutaneous fat and still risk your cardiovascular health because of visceral fat. To be clear, however, this problem has been somewhat misrepresented in various reports. While thin people can have an accumulation of visceral or "intra-abdomnal" fat obese individuals will tend to have more of it, especially men. Unless their activity levels are very unusual for an obese person, such as a sumo wrestlers, who have been found to have a remarkable lack of visceral fat, probably due to their training (although dietary practices could play into this as their diets are fairly unusual for athletes, although very high in calories). For more on this see Metabolically Healthy Obesity and The Almighty EWAG and Some Big Old Belly Fat: How Strength Training Justifies Being Overweight.
In general, you cannot work off a bad diet. The way you eat, or don't eat is the KEY to fat loss and the key to keeping off the fat. Exercise is a factor in that. All strenuous physical activity is a factor. A big one. But not the KEY. The person telling you that strength training will make you thin…has probably never been overweight.
