Hello! Thank you for writing! I have gone through your question and understand your concern. First of all I congratulate you for the right information that diet pills have on your body. Oxyelite Pro is known for its dangers and the history of oxyelitePro in liver/heart failures as well as stroke, multiple reformulations with FDA taking it off the market several times and then finding the company putting Prozac in its pills and trying to sneak DMAA (banned by FDA)back into the product. I suggest you not to take it, better try a healthy way of losing weight. Exercise 4-6 times per week and eat healthy. Exercise has been proven to be as effective (or more) than many drug treatments for common health problems, including diabetes, heart disease and depression, just to name a few. So, exercise definitely plays a role in optimal health — it s just not the central key for weight loss. You cannot keep eating a junk food diet and simply exercise your way into smaller pants. Additionally, when and how much you eat can also have a distinct influence. Eating less and paying attention to the timing of your meals can be particularly useful for kick starting your metabolism in the right direction. Indeed, one of the simplest ways to improve your ability to burn fat as your primary fuel and lose weight is to replace all sodas and sweet beverages with pure water. Condiments and snacks are other categories that can be eliminated without risking nutritional deficits, thereby lowering your overall calorie consumption. General Implementation Guidelines To regain the ability to burn fat as your primary fuel you need a diet high in healthy fats, adequate protein and low in net carbs (total carbs minus fiber). The first step is to eliminate packaged, processed foods. The emphasis is on real whole foods, plenty of healthy fats and as few net carbs as possible. There are far more details in my new book, Fat for Fuel, that comes out in mid-May and will soon be available for preorder along with many great bonuses. As a general rule, it s recommended you reduce your net carbs to 50 grams a day or less, and restrict protein to 1 gram per kilogram of lean body mass. To make sure you re actually meeting your nutritional requirements and maintaining the ideal nutrient ratios, a nutrient tracker can be an invaluable tool. Another key to success on a high-fat, low-carb diet is to eat high-quality healthy fats, not the fats most commonly found in the American diet (the processed fats and vegetable oils used in processed foods and fried restaurant meals). Examples of high-quality healthy fats include: Olives and olive oil (make sure it s third party-certified, as 80 percent of olive oils are adulterated with vegetable oils. Also avoid cooking with olive oil. Use it cold.) Coconuts and coconut oil (excellent for cooking as it can withstand higher temperatures without oxidizing) Animal-based omega-3 fat such as krill oil and fatty fish low in mercury like wild caught Alaskan salmon, sardines and anchovies Butter made from raw grass-fed organic milk Raw nuts, such as macadamia and pecans Seeds like black sesame, cumin, pumpkin and hemp seeds Avocados Grass-fed meats MCT oil Ghee (clarified butter); lard and tallow (excellent for cooking) Raw cacao butter Also make it a point to walk more every day and stay more active throughout your working day. Researchers have clearly identified sitting as an independent risk factor for chronic disease, increasing your mortality risk from all causes. So, standing up more and engaging in non-exercise movement as much as possible is just as important for optimal health as having a regular fitness regimen. Thank you. Best regards.
