Only lean tissue burns calories so this is what you need more of. If you crash diet and lose more than 2lb a week your body ditches mainly muscle as it thinks you are starving and slows your metabolism. Therefore unless you want to end up with more body fat you should never lose more than 2lb a week. (Fat is also 10 times bigger than muscle so you definitely don't want your losses to be muscle!)
Interval training increases metabolism. Train at 85-95% of your maximum heart rate for 30 seconds then drop down to about 70% for 90 seconds. Start off doing at least 20 mins 3 times a week and work your way up from there. The easiest way to do it is by combining sprinting and walking uphill. It really works!
Doing excersise before meals boosts your metabolism so that when you eat it is burnt off faster than if you hadn't excersised. Always eat breakfast within half an hour of waking up in the morning, and take a cold shower in the morning too. Try to eat before 7 o'clock in the evening so that your metabolism has a chance of burning off everything before you go to sleep, and good luck :)
Strength training builds muscle mass, which activates your metabolism.
Muscle is an active tissue, and it’s the engine that will rev up your metabolism. That's because muscle burns more calories than fat.
Building muscle is the most fundamental component in staying lean. Think of muscle and metabolism working together - like a partnership. The more muscle tissue you have, the higher your metabolism and the more calories you'll burn when you rest. The less muscle you have, the less calories you'll burn. The best way to get your metabolism to work faster so that you can burn more calories, is by building more muscle - lifting weights and strength training. Losing weight doesn't happen just by eating little and doing some cardio; that plan can actually slow down your metabolism. One pound of muscle burns 75 calories, while one pound of fat burns 2 calories.
Eat several small meals each day. I eat 5 or 6 times per day. Another helpful thing is to move around at least once an hour, if you have a sedentary job...go climb up and down the stairs a few times, take a quick walk around the building, just 5 quick minutes of moving ever hour will help a whole lot. Consistency is really the key. Strength training is really essential, also. A few resistance bands at home can do the trick...you don't have to become a gym queen to get nice results.
Sea kelp is proven to speed up your metabolism, and can be bought from most health food shops. Taken in conjunction with a healthy diet and regular exercise you can reach your ideal weight and shape within months.
Increase metabolism by spicing up your life. Ever wonder why most women in asia are skinnier? It's because they eat spicier foods than the non-asian women. Spicy food boosts metabolism. And I guess the almost year-round hot asian weather has something to do with it too. Sweat more, loose more.
