Eating healthy is really important if you want to be a healthy teen. You don't need to go on a diet, just pay attention to what you're putting in your body.  If you only ever eat sugary breakfast cereals and candy bars you aren't going to be healthy. Depending on your body and what works best for you, you can eat three meals a day or 5-6 mini-meals a day. NEVER skip meals. Try healthy alternatives, instead of having a bowl of ice-cream, opt for a frozen yogurt. Or try having apple slices instead of potato chips. Try to replace processed foods, especially those which contained added sodium and sugar, with whole natural foods like fruits and vegetables. Drink more water. This is basically the most important thing of all. If you drink more water you will be much healthier. It flushes the toxins out of your body and gives your skin a healthy glow. It also keeps your skin hydrated and helps prevent spots. It also helps if you have acne. As a rule of thumb, try to drink a lot to the point where your urine is almost completely clear. As a rule of thumb, try drinking half of your body weight in water everyday. Whether it's walking in the park, or doing a couple of crunches do at least 30 minutes of physical activity several times a week.  You should not exercise every day, when you work out you break your muscles down. It's the rebuilding that makes them stronger. If you don't give them time to rebuild, you're going to seriously hurt yourself. Try working out for 6 days a week and give yourself 2 days to rest and recuperate. Exercise will make you stronger and tone your muscles. You  can go to the gym and swim or run on the treadmill, buy a few work out DVDs, or just go for a jog around the block. Whatever it is, exercising will make you healthier and happier about your body. It also releases oxytocin which helps reduces stress and calm the mind! During puberty you'll find you need more sleep than you did when you were younger. Sure it's tempting to stay up late chatting with friends on the phone or computer, but the next morning you'll be miserable   You need to get a minimum of 8 hours of sleep every single night. To find out how many hours you personally should be sleeping, on a weekend go to bed at the time you do on a school night and don't set your alarm. When you wake up count how many hours you were asleep and get that many hours every night. It may be tough if you get back late and have to wake up early on a normal school day, but if you put the extra effort in of an early night you will feel much more refreshed the next morning. This will aid your concentration and you will be in a much happier and friendly mood. Also try to get the same amount of sleep everyday so that your body is adjusted to it.

One-sentence summary -- Start eating healthier. Start exercising more. Catch up on your sleep.

Q: You can make pumpkin puree out of any type of pumpkin, but for the most concentrated flavor (and the best for making pie), go for the smaller pumpkins that are intended to be used in recipes, rather than choose jack-o-lantern sized squash. Each pumpkin will yield a cup or so of puree.  Look for pumpkins with bright orange flesh, no big bruises or gouges, and a relatively uniform shape. Heirloom pumpkins often have striated colors like yellow and green in addition to orange. These make great puree, too, but the color may not be the classic bright orange you're used to. Avoid decorative baby pumpkins - these don't contain enough meat to make much pumpkin puree, and they aren't grown to be eaten. Run them under cold water and scrub away any dirt or other debris, especially if you got the pumpkins from your garden or a pumpkin patch. Start by chopping off the stems, leaving as much of the body intact as possible. Next slice the pumpkins in half, revealing their seeds. Use a large spoon to scoop all of the pumpkin seeds from the halves into a bowl. Save the seeds for later, since they're  delicious roasted. Scoop out as many of the orange strings as you can, too. Finish processing the pumpkins by slicing the halves into quarters. You should now have 8 (or more, if you're using more than 2 pumpkins) wedges of pumpkin to work with.
A: Get small pie or sugar pumpkins. Wash the pumpkins. Cut the pumpkins. Scoop out the seeds. Slice the halves into wedges.

Problem: Article: Red onions go great for this recipe; with their distinctive taste and deep red color, they actually turn pink after a couple days in the refrigerator. You can slice the onions to the thickness you prefer — however thick, they'll still take the pickling solution. Some people prefer to cut the onions in a full moon, which makes them easy to grab with a fork; others prefer them smaller, cut them into half moons. Heat enough water to completely submerge the sliced onion. Throw the cloves, cinnamon, chili, and thyme into a pot and toast them over medium-low heat until they become aromatic, about 3 - 5 minutes. Count to 10, and then strain the water and onions through a sieve. Why parboil the onions? Parboiling removes a little bit of the acid zing from raw onions. You don't have to parboil if you like the zing of raw onions, but a slightly mellower onion makes the pickling juice really stand out. You can let the onions rest there or remove them after 10 seconds. Onions which are left in the ice bath will continue to mellow while the sulfur compounds (the onion's natural defense) diffuse into the water. Once onions are done, drain them completely and place them into a container. Turn on the burner to medium high and bring the pickling juice to a simmer, dissolving the sugar completely. Simmer for an additional minute. Seal the container and place into refrigerator. The pickled onions will be ready to try in as little as one hour, but are best after at least one day. Store pickled onions in the refrigerator for up to 2 weeks. Red onions which are pickled will turn slightly pink as they age. Try your pickles on homemade tacos, sandwiches with richer cuts of meat (like pork), or a hearty stew.
Summary:
Halve, peel, and slice the onion. Heat some water over the stove or in a kettle. While the water begins to boil, toast the spices in a small pot. When the water is just about to boil, remove it from the heat and add the onions to the water. Transfer the onions from the sieve to the ice bath to stop them from cooking. Add the vinegar, lime juice, and 1/4 cup of sugar to the toasted spices. Remove the pickling juice from heat and pour into container with onions. Enjoy.
