Originally Answered: Dieting tips.
Eat a wide variety of foods from every food group. Don't listen to anyone who tells you to to Low carb or Low fat or low any whole food group. You want to cut back on the "bad carbs", those that raise your blood sugar quickly and have few or no nutrients, and the "bad fats", mainly saturated and trans fats. Bad carbs include refined sugar, refined white flour (to include white pasta, white bread, rolls etc.) and the obvious- most candy and pop. Bad fats are mainly saturated, and found in milkfat and fatty cuts of meat. Eat low fat or skim milk along with lean protein- like grilled or baked chicken or fish, or extra lean ground beef. Trans fats are mainly found in processed, packaged foods; you should eliminate as many of these from your diet as possible anyway, owing to the fact that these foods tend to be heavy on sugar and sat. fat besides.
Try and make the bulk of your diet whole plant foods- Fruit, vegetables, whole grains, nuts and seeds. Most of these have a very high amount of both good nutrients and taste.
Outside of that, do whatever exercise you find most enjoyable, whether it be long walks, jogging, vigourous calesthenics or hitting the gym.
As one other answerer said, it is important to make lifestyle changes, rather than to go on a diet that you eventually go back off of and gain weight. Try cutting out pop and/or candy at first, or switch to healthier alternatives, such as diet instead of regular pop, or extra dark chocolate instead of milk chocolate. Try switching down to a lower fat kind of milk and using chicken or chunk light tuna instead of beef.
No matter what, keep confident and don't let anyone get you down. You can do anything you set your mind to, remember that.
Hope this helped.
