Dietary medium chain triglycerides (MCTs) and medium chain fatty acids (MCFAs) cannot be stored by the body, so they need to be burned immediately upon absorption from the small bowel, as a buildup of MCFAs in the bloodstream is dangerous. So if one’s intake of MCT/MCFA at any point in time is greater than one’s peak fat oxidation capacity, the liver has to step in and reduce the toxic excess of MCFAs to ketones, which are more readily used and far less dangerous. While this rise in ketones induced by MCT oil consumption can trigger some of the epigenetic benefits associated with nutritional ketosis, it does not induce the accelerated ability to burn fat associated with keto-adaptation. And this has implications for our quest to understand the relationship between ketones and weight loss.
Since we can’t spot reduce fat, the only way to ever get those flat abs is to burn body fat overall. For this reason, HIIT workouts, exercises that work multiple muscle groups simultaneously (like push ups, squat thrusters etc.), and weight lifting are going to be the most effective fitness strategies for bringing out your six pack because they are the most metabolic. Hours of cardio and tons of crunches are not the way forward here.
Nuts, the second food to watch, contain a fair amount of carbohydrate, and it’s very easy to unwittingly scarf down large quantities. Cashew nuts are among the worst carb-wise – you’ll find that they contain around 20% carbohydrate by weight. For someone following a strict keto diet with a 20 grams of carbs per day allowance, this means that consuming 100 grams (which happens in a flash!) will have filled their daily quota. Peanuts tend to be around 10-15% carbohydrate – not putting them in the clear either.
Arteries (are-te-rease): The blood vessels that carry oxygen-rich blood away from your heart for delivery to every part of your body. Arteries look like thin tubes or hoses. The walls are made of a tough outer layer, a middle layer of muscle and a smooth inner wall that helps blood flow easily. The muscle layer expands and contracts to help blood move.
Satisfying your sweet tooth doesn't require a refined sugar-packed snack. The key is retraining your taste buds to recognize naturally sweet foods, like fruit. "To curb my hankering for treats, I eat mangoes," says Tamyala Ezell, who lost 105 pounds by making over her eating habits and working out three times a week. "They have a natural sweetness that does the trick. Plus, they're low in calories and high in fiber." Another example? "I top berries, nectarines, and cherries with homemade whipped cream, nuts, and dark chocolate," says Goetke.
An article published in Consumer Reports in 2006 recommends avoiding the fat-burning supplements 5-hydroxytryptophan, or 5-HTP, and citrus aurantium, also called bitter orange, as these both have potentially serious side effects. Bitter orange can cause increased heart rate, anxiety and chest pain, and 5-HTP can cause inflammation and pain in the joints and muscles and severe gastrointestinal issues. Another article, published in the Canadian Journal of Gastroenterology in 2011, notes that an herbal fat-burning supplement containing usnic acid, guggul tree and green tea extracts was linked to a case of liver failure.
Gina Harney started The Fitnessista after she’d already lost 40 pounds. At the time, she was in maintenance mode in Georgia where, as she explains it, “healthy options were pretty scarce.” The blog was her way of chronicling how she sought out those healthy choices and often created them for herself. Today, Gina works as a certified personal trainer, group fitness instructor, and weight loss specialist. She loves sharing tips with her readers as they embark on their own journeys toward health.
