The first thing you have to do to lose weight is cut out high-fat and high-sugar items from your diet. A pound of fat is about equivalent to 3500 calories, so cutting out a few hundred calories a day can help you lose weight fast. Salad dressing, soda, fancy coffee, sweets, and butter are all easy things to cut out of your diet. You can also make choices, like choosing lean meat over fatty meat, or choosing to have whole wheat instead of white bread. It is important to eat breakfast in order to jump-start your metabolism in the morning. Also, watch portion sizes and be careful not to eat too much of one thing, even if it is good for you (other than vegetables of course!).
Cutting food out might not be enough. Dieting, while extreme, is a highly effective way to lose weight quickly. Sticking to whole grains, protein, and lots and lots of vegetables is a simple and healthful dieting. Crash dieting works as well, but making a healthy diet choice for a longer period of time is healthier and more long-lasting than essentially starving yourself. In addition, crash dieting is not conducive to cardiovascular exercise or resistance training. If you are interested in making serious diet changes, seeing a nutritionist is a good idea.
Though you may not be physically fit, it is vital that you do cardiovascular exercise at least 4 times a week, working up to 6 days a week if you can. Be careful not to increase your workload too quickly, especially if you are inexperienced, as this could result in injury. Sessions should last between 30 minutes and 45 minutes for maximum effect.
While aerobic exercise will help you lose weight, you need to do weight training and other exercises to look fit, instead of simply skinny. Lunges, squats, and sit-ups are all easy to do in your own home and can be intensified by adding weights or incline. While muscle weighs more than fat, and thus your number on the scale might be higher, you will still look leaner and have a faster metabolism. That is why building muscle is an effective way to lose weight; it quickens your metabolism!
Good luck on your way to a trimmer and more beautiful self!
