Ketones (beta-hydroxybutyrate [BOHB] and acetoacetate [AcAc]) are produced by the liver when both serum insulin and liver glycogen levels are low (McGarry 1973). They can be made from fat stored in the liver, from fat released from body adipose reserves and delivered via the bloodstream; or they can be made from dietary fat entering the bloodstream after digestion and absorption as chylomicrons. In other words, once fat is in the body as adipose reserves or absorbed dietary fat, liver ketone production is a function of blood insulin and liver glycogen content. There is no special relationship between mobilization of body fat stores (i.e., weight loss) and blood ketone levels.
We don’t recommend thinking about macros in terms of percentages, especially if you’re focused on weight loss. We recommend keeping your carb intake under 30 grams/day, eating the protein requirement we outline in our protein post, and eating fat to satiety. There’s more info on our rationale around macros in this post by Steve Phinney and Jeff Volek: https://blog.virtahealth.com/how-much-protein-on-keto/
Keep your exercise regimen interesting. Variety is the key to both promoting a healthier you and keeping you motivated. When you do the same exercise day in and day out, you put yourself at a higher risk of injuring yourself. You are also more likely to become bored, thus making it harder to find the motivation to keep exercising. While at the gym, switch between machines, join a fitness class, and add some resistance training into your schedule.
Thank you for offering a simple diet plan and sharing your results. I have been on a personal journey to lose weight and have been unsuccessful for many years. I am making a 2 week commitment to stick to the diet plan you have outlined. My biggest problem is night time eating and very low self-esteem. I am looking forward to starting this. Any suggestions for me? Thanks!
But before we do, we need to acknowledge that these questions have sparked an intense debate among serious scientists and the lay public over the last 15 years, and in the process sparking the expenditure of tens or millions of dollars on research in which both sides of the debate strove to prove the other side wrong. While we will discuss some of this research, much of it involving short-term studies done under artificially controlled conditions, we will also try to anchor this discussion with a perspective drawn from research utilizing well-formulated ketogenic diets for meaningful durations in the real world.
In what is perhaps the biggest buzzkill of all time, sex doesn’t quite count as cardio or burn a significant amount of calories: Women burn about 3.6 per minute. "It’s still a good idea," Dr. Seltzer says, citing the activity’s other benefits, like increasing the output of the neurotransmitters serotonin and dopamine, which naturally reduce food cravings.
Certain foods that burn belly fat and increase metabolism are great. Some foods actually take more energy to burn (or more calories) than the calorie content of the food, which results in negative calories. Most of these foods are natural plant foods. Enzymes are needed for a good metabolism, and enzyme deficiencies are often caused from not eating enough fresh food. Protein and dairy products are helpful at burning fat also.
