If you want to lose fat with only diets and without any aerobic or weight training then you are destined to fail. Going on a strict diet will almost certainly make you lose lean body mass. Weight training is the only way to keep your lean body mass whilst dieting for fat loss. Keeping your lean body mass is very important because the more muscle you have the more calories you burn at rest.

Most people often have only pieces of a puzzle and that is why they never lose fat permanently. To lose fat permanently you need the right nutrition, cardio training, weight training and motivation. If you leave out one or the other then losing fat is very difficult. The effects of these four disciplines put together are far greater than the sum of their parts. That is called “synergism.” Synergism means that 1 + 1 + 1 + 1 might not equal four, it might equal 10, 50 or 250. And weight training is one of these very important factors.

Weight training has a huge impact on fat loss. It is not only building muscle or increasing strength. Weight training increases your lean body mass (LBM). The faster your LBM is the faster your metabolic rate is and the faster your metabolic rate is the more calories you burn at rest. The more muscle you have the faster your basal metabolic rate (BMR) is.

Example:

BMR (men and women) = 370 + (21.6 X lean mass in kg)

If someone weighs 75 kg and has 20% bodyfat then the lean body mass (LBM) is 60 kg.

BMR= 370+(21.6×60)
BMR= 1 666 calories

But if he had 10% bodyfat and also weighed 75 kg, then his LBM would be 67.5 kg. If you do the same calculation again then now he would burn 1828 calories. That is an extra 162 calories a day. There are 3500 calories in a pound of stored body fat. 3500 divided by the extra 162 calories would be 21.6. That would be an extra 1 pound of fat lost after every 22 days. If you previously had any doubts if weight training burns fat then now you know.
