How to lose those last few pounds
The mistake that people make too often is trying to lose fat with reducing their calories and aerobic training. Both of these factors are very important, but people often neglect one other important factor - strength training. For a person who is overweight, it may seem that people who are thin, even though they don't eat the right foods are just lucky.
The secret to lose those last few pounds and get really lean is muscle mass. The more muscle mass you have the faster your metabolism is, so you burn more calories. Aerobic training burns a lot of calories during a workout but it has little effect on your metabolism. If you combine both strict diet with intense aerobic training, then you certainly lose muscle. So if you are trying to lose those last few pounds then losing muscle mass is a very big danger.
So the only way to maintain and gain muscle is with strength training. You may not be able to build muscle when you are on a relatively strict diet or do intense aerobic training but will at least maintain muscle. When you are doing strength training, then do not reduce your calories drastically. You need a lot of energy to do aerobic and strength training and if you go below 2100 calories for men and 1800 for women, then you just don't have the energy. Do not starve the muscle but feed the muscle.
