I have been Keto for over a year, always used coconut oil in my bullet-proof Tea in morning. Mostly because I thought it wasn't worth the extra money. Still feel great on Keto but weight loss had plateaued, 2 months ago I switched to MCT oil, it has made a big difference, get into ketosis faster, more energy and satisfied longer, makes intermittent fasting easier. Best of had to buy all new pants a size smaller...woo-whoo. My bullet-proof Tea, I make a pot of green tea with fresh ginger, night before, in morning I heat up lg cup of tea, and blend with 1 tablespoon KerryGold (Grass-fed) Butter, 1 tablespoon MCT oil, 1 scoop Collagen peptides. It's yummy, creamy/foamy like a latte. Most people make bullet-proof "coffee" and some add heavy cream as well. Keto Side note: For over 10 years ago I was suffering from various health issues, thyroid, autoimmune, weight gain, acid reflux, back and neck pain, Allergies and sinus issues. Various Doctors all had me taking different meds for each alignment, but I felt terrible all the time. A friend suggested seeing a integrated medical doctor. He felt all my health issues were related and basically caused by an imbalance of good and bad bacteria in gut that can lead to inflammation and many serious health issues. Taking probiotics would not be enough, bad bacteria craves sugar and carbs, to restore balance I had to cut their food supply. It made sense but not sure I believed it would really help but worth a try. Giving up sugar, wheat and processed foods, seemed impossible and was a hard adjustment basically followed Paleo. But after 1 month of low carb, felt a real difference, after 3 months felt even better and losing weight, by 6 months amazing, health issues disappearing and no meds at all. Later I discovered Keto and made giving up sugar and grains much easier, when you use healthy fats to fuel your body, you are satisfied, not hungry and cravings disappear. At 51 I feel younger and better than ever
