Can I have dairy products on the low carbohydrate, high protein diet?
While low carbohydrate diets focus on limiting sugars and starches, navigating dairy products can be tricky. Many dairy products, especially cheeses and yogurts, are naturally higher in protein and lower in carbohydrates than other food groups. However, milk, while providing calcium and protein, contains significant carbohydrates in the form of lactose. Choosing full-fat high protein cheeses like cheddar, Swiss, or Parmesan can be beneficial, while plain Greek yogurt can be a good source of protein and probiotics on a low-carb diet. Opting for unsweetened, almond-based milk alternatives can be a good alternative to cow’s milk if you’re sensitive to lactose or aiming for strictly low carbohydrate intake. Remember to check the nutrition labels carefully as carbohydrates can vary between brands and types of dairy.
Can I use oil or dressing while cooking my meals?
When it comes to cooking, incorporating healthy fats into your meals can elevate flavors and provide essential nutrients.

However, not all dressings and oils are created equal, and including them in excess can be detrimental to your health. To strike a balance, you can create homemade salad dressings using vinaigrette recipes made with healthy oils like olive oil, mustard, or citrus juice. For instance, a simple vinaigrette can be created by whisking together 2 tablespoons of olive oil, 2 tablespoons of apple cider vinegar, 1 teaspoon of Dijon mustard, and a pinch of salt and pepper. As a general rule of thumb, opt for dressings and oils that are low in added sugars, artificial preservatives, and saturated fats to ensure you’re getting the most nutritional benefits from your cooking. By making mindful choices about the oils and dressings you use, you can take charge of your meal prep and indulge in delicious, nutritious meals.
Should I avoid taking any medications before the PET scan?
Before undergoing a PET (Positron Emission Tomography) scan, it’s crucial to discuss any medications you’re currently taking with them, as certain drugs may interfere with the test results. In particular, diabetic patients should avoid taking insulin or glycemic control medications least 2 hours prior to the scan, as these can affect blood sugar levels and, consequently, the scan’s accuracy. Additionally, certain medications like formin, iodine-containing medications, and caffeine should be avoided for at least 24 to 48 hours before the test, as they can alter the body’s metabolism and radiotracer uptake. However, do not stop taking any medications without consulting your doctor’s approval, as this may lead to adverse health effects. By understanding which medications to avoid, you can ensure accurate PET scan results, which are essential for effective disease diagnosis and management.
Can I chew sugar-free gum on the day before a PET scan?

By adhering to these guidelines, you can ensure a successful and accurate PET scan, providing your healthcare provider with the necessary information to diagnose and treat any underlying medical conditions.
Can I eat nuts and seeds on the low carbohydrate, high protein diet?
Following a low carbohydrate, high protein diet doesn’t mean you have to give up on healthy fats and nutrients. In fact, nuts and seeds are excellent additions to this dietary style. Packed with protein, fiber, and healthy fats, they can help you stay full and satisfied between meals, keep your energy levels stable, and provide essential vitamins and minerals. For optimal results, choose unsalted varieties and enjoy them in moderation, as they are naturally higher in calories than some other protein sources. Some great options for low-carb snacks include almonds, walnuts, chia seeds, flax seeds, and pumpkin seeds.
Can I have flavored herbal teas on the day before a PET scan?
When preparing for a PET scan, it’s essential to understand the dietary restrictions to ensure accurate results. Generally, patients are advised to avoid consuming anything that may interfere with the scan, particularly substances containing caffeine or sugar. Flavored herbal teas are often considered a safe choice, but it’s crucial to check with your healthcare provider or the facility conducting the scan for specific guidance. On the day before the scan, you can likely have herbal teas that are free from caffeine and added sugars, but be cautious of any ingredients that might be contraindicated. For instance, some herbal teas may contain ginseng or other stimulants that could potentially affect the scan results. To be on the safe side, opt for a simple, unflavored herbal tea like peppermint or chamomile, and confirm with your healthcare provider that it’s acceptable.
Should I avoid exercise before a PET scan?
Avoiding exercise before a PET scan is crucial to ensure accurate results. Engaging in physical activity before the scan can lead to increased glucose uptake in muscles, causing false positives or inaccurate readings. This is because PET scans measure glucose metabolism in the body, and exercising muscles may show up as areas of high activity, potentially masking or mimicking cancerous cells. For instance, if you’ve been running or lifting weights before the scan, your muscles may still be metabolizing glucose at an elevated rate, leading to potential misinterpretation of the scan results. To avoid this, it’s recommended to refrain from strenuous exercise for at least 24 to 48 hours before the PET scan. Additionally, avoid caffeine and sugar intake, and follow your doctor’s specific instructions to ensure the most accurate and reliable results.
