Article: While you may feel tempted to skip breakfast or spend a day fasting, you should resist the urge to do so. Prolonged fasting can cause muscle loss and other health problems, but it can also make it more difficult for your body to lose weight. When the human body does not receive enough nutrition, it automatically starts conserving calories by burning them at a slower rate. You may experience significant weight loss after the first few days, but by the end of the two weeks, you will probably gain a good portion of it back. The exception to this is if you're on a highly-regimented intermittent fasting plan. This is where you don't eat anywhere from eight to twenty-four hours and then eat planned amounts of calories (often more) thereafter. While this can be effective, do this only with the approval of your physician. If you don't do it correctly, you could actually increase your body's tendency to store fat. Many people find success with a timed plan. That is, they decide that they won't eat after a certain time, usually somewhere around 7 to 8 pm. Nighttime eating is generally the worst for most people, as the TV is on and friends are habitually munching, too. This can be emotionally difficult, but it can pay off. You may need to be reasonable with yourself. Have this rule for only five or six days out of the week. Give yourself some wiggle room to go out with friends – but that doesn't mean you can go crazy. Stick to a glass of red wine and a few bites – don't eat the entire buffet. The idea that it's all about calories is slowly becoming old school. The fact of the matter is that everybody's body is different and not all calories are made the same. What's more, counting calories sucks. That being said, they're a good general guideline. For the purposes of this diet, budget your calories throughout the day. If you've done really, really great, have that piece of dark chocolate or that extra half a chicken breast. Don't go overboard, but keep yourself from feeling deprived. You'll want to balance the calories you burn with the calories you consume. In other words, the more you work out, the more you can eat. Weight loss generally occurs when you burn more calories than you consume. On average (again, on average), a person needs to burn 3,500 calories more than he or she consumes to lose 1 lb (450 g). To lose 20 pounds (9 kg) in two weeks, you will need to lose a little under 1.5 lbs (675 g) every day. That means burning a little over 5,000 calories more than you consume each day. Yep, a very, very tall order. It's not just about what you eat, it's also about how much you eat. Even the healthiest of foods need to be eaten in moderation. Start by using smaller plates and smaller eating utensils and don't go back for seconds. Adhere to the serving sizes listed on the nutrition labels and look up anything you're unsure about. Snacking is where portion control gets iffy. To avoid that handful of nuts turning into the entire bag, measure out your snacks beforehand. Then when you're hungry, you grab a little baggie or container that's the right serving size and that's that. You know exactly how much you're eating. Intermittent fasting and calorie cycling is becoming more and more popular. These practices maintain that sometimes a lot of calories is a good thing, as it keeps your body from down regulating (where you stop burning calories). One week through your diet, consider having a little fun with your eating – it may help keep your diet on the right track. If this diet were to last longer, you might want to devote an entire day to eating. Eating whatever the heck you want. However, it may be best to limit yourself to an hour or two during this fourteen-day period. So for 60 minutes one day this week, go to town. But beyond that, you have to get back to your plan. Make sure to read that third word – eat more often, not eat more. Think of it this way: if you only have 5 pieces of celery you can eat in a day (not recommended; just an example), you don't want to eat them all for breakfast. You want to space them out to keep from being hungry. Along the same lines, you're likely not eating a lot in these two weeks. So eat less, but eat less more often. It'll keep your stomach from thinking it's hungry. Many healthy diets advocate snacking and for good reason – it keeps your metabolism up and it prevents you from gorging yourself later. Make your meals smaller so you can fit in a few extra calories for snack time. In two weeks, your body and your motivation will thank you for it.

Problem: Article: If you have had her since she was a puppy, then you will know if she has been neutered (had her womb removed) or not. However, if the dog came to you as an adult from a rescue center, then you might not know for sure. An entire (unneutered) Female dog comes into heat twice a year, so if you have owned her for well over nine months and she has not been in heat, the likelihood of her being neutered increases.  While the duration of heat, or estrus, depends on the individual dog, it averages about 18 days. Dogs usually experience their first heat between six and 24 months of age.  See the next steps for signs of heat. When your dog is in heat, you can observe changes in her vaginal area.  An enlarged, swollen vulva: The swelling in the external area of her vagina often lasts around four weeks, from shortly before the heat starts, to just after it finishes. Vaginal discharge: In the first seven to ten days of heat your dog may spot blood. It is helpful to put a white sheet in her bed and check for tell-tale signs of blood spotting. If your dog is fastidious, she may spend a lot of time washing her vulva, so the discharge may not be obvious. This discharge becomes lighter in the middle seven days of the season (which is when she is ovulating and most likely to get pregnant), and then returns for the final seven to ten days of the heat. When your dog is in heat, she is experiencing a major hormonal event that usually causes a change in her behavior. How exactly she changes depends on her personality; it may mean that if she's usually placid, she'll become snappy and short-tempered, or if she's home-loving, she might suddenly get the desire to escape and go wandering. Aside from these changes, your dog should be otherwise well. If she lacks energy, loses her appetite, vomits, or drinks heavily, contact a vet for advice. Other womb conditions such as pyometra (pus in the womb) can mimic heat in rare cases, and may be life-threatening if left untreated.
Summary: Determine whether your dog is spayed. Look for vaginal abnormalities. Track behavioral changes.
