Switching from carbs to ketones does not happen overnight – it takes weeks of consistently restricting carbs for this process of keto-adaptation to fully occur. But once this process is complete, the body can burn fat at over twice the rate compared to when carbs were a major component of the diet (Phinney 1983, Volek 2016). And this remains true even when comparing highly trained athletes, where we have shown that high-level endurance training in the context of a high carbohydrate diet cannot come close to matching keto-adaptation in giving the body permission to burn fat.

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.
Thanks for sharing Brittany! I love your honesty and could not have used this post more today. I have been struggling with weight gain the last couple of years and keep falling into this loop hole of not eating clean. I work out 5 days a week, however my diet has not changed and so I have struggled. I will be definitely looking into this book as well to give me a new outlook and starting point. Kudos to you to maintaining a busy life of family, running a business and healthy lifestyle. I am inspired that if someone like you can make the change anyone can! Hugs
Dear Stefani, I am 65 years old and I would like to ask, what is your advice for post-menopausal women in regard to carbo-cycling? For the past 8 months I have practiced IF (fasting nearly daily, between 16 and 24 hours) combined with carbo-cycling (extremely low carbs for 3 or 4 days in a row followed by 1 day of carb reloading) to dramatically reduce my calorie intake while eating nutritious foods only. As a result, I have lost 70 pounds. Now that I am at a good weight and feeling well (I exercise daily), I would like to think I can use IF and carbo-cycling when necessary to avoid regaining weight. But I am concerned by the possibility that I may actually be undermining my body’s insulin sensitivity.

I’m 5′ 2″ or so, and about 102 pounds. I’m 19. Not that long ago, I was only 94 or so, and I eat very healthy (lean protein, fruits, vegetables). My one “no-no” is Starbucks in the morning, but I’ve always done that, even when I was thin. I want to drop the 8 pounds I gained ASAP. I used to be very tone, and I feel like all that has gone away. What do I need to do. Please help.
"Crash diets (dramatically cutting down how much you eat) might help you to lose a few pounds at first, but they’re hard to sustain and won’t help you keep the weight off. It might seem like a quick and easy option, but eating too few calories can actually do more harm than good. If your calorie intake dips too low, your body could go into starvation mode. This will slow down your metabolism, making it harder for your body to lose weight. Make sensible, healthy changes to your lifestyle that you can stick to and avoid the fad diets."
Fast forward several years later, I had another baby (Winter) and came out of that pregnancy about 40-50 lbs over my end goal weight. I had always had this dream to finally hit the big “100” in weight loss. By 2013 I had begun to take some classes at the gym and count calories a little more but I in NO WAY did anything extreme. And I honestly believe that is the key to weight loss and to keeping it off. It was NO quick journey to that final number but by July 2013, I hit 120 lbs and had officially lost 100 lbs…
"If your diet consists of lots of sports drinks, sugar-sweetened drinks like fizzy pop and flavoured waters, or sugary foods like chocolate and cakes, it will make losing weight harder. While whole fruits and vegetables are undoubtedly good for you, they can also sometimes cause weight gain if you eat too much, as they have high levels of natural sugars in them. Low-fat food options might have high amounts of added sugar in there too, so make sure to check the food label.
Fast forward to the present. In terms of weight loss, I have kept off those 50 pounds, but it took me over a year to find a comfortable weight. More important, I am not as focused on losing weight but on building lean muscle and getting toned. My energy levels, positivity, confidence, and purpose are more important than size and weight. In terms of nutrition, I prioritize eating wholesome foods and nourishing meals; and I am learning more about the ratios and best foods to fuel my body for my lifestyle. For exercise, I still consider myself a runner though and through, but I have struggled with some injuries. I tend to go super hard at the things I love, so I have gone in and out of working my body too hard. That being said, I have been mixing up my workouts with running (I have a destination half marathon planned for March!) and more lifting (thank you to Lindsay for all of the lifting plans!) and yoga (Yoga with Adriene is amazing.) I have also had an epiphany on self-care, but that’s for a different post. I am working towards real-deal peace and happiness. I’m getting fit, healthy, happy, indulge when I want, have confidence in what I’m doing and the choices I make daily, know my way around a kitchen, and listen to my body.
But here’s a problem that many people experience. They have been told that increasing blood ketones will speed their weight loss. However, rather than cutting back on carbs and avoiding extra protein to boost ketone levels, they are led to believe that they can get the same effects by adding extra MCT oil, coconut oil, or exogenous BOHB to push up blood ketone levels. As noted above, this does not enhance their body’s ability to burn fat. It just gives them a type of fat that has to be burned (some of it as ketones) in place of body fat. No wonder they are usually disappointed when their weight loss stalls well above the goal they want to reach.
I also started doing home exercise programs and found them to be highly effective. No more money and hours wasted at the gym. But now for maintenance, I only do high-intensity interval exercises with basic equipment (dumbbells, kettlebells, bodyweight) at home. Only 20-30 minutes for 3-4 days a week will keep your metabolism high and continue to burn fat throughout the day.
"Your body needs a healthy balance of exercise and rest. Doing too much prevents the body from shifting excess fat. Exercising without rest can impact our levels of the steroid hormone cortisol and cause an increase of stubborn fat stored in the belly. Not allowing your body to recover can increase the risk of injury too, so make sure you factor in rest days to your plan."
"When we’re lacking in sleep, our body’s hormones get thrown off balance which can impact our hunger levels the next day. We all have two hormones that affect our appetite: ghrelin and leptin. When we don’t get enough sleep, our ghrelin levels (the hormone that makes us feel hungry) rise, and our leptin levels (the hormone that makes us feel full) drop. This means that when we’re awake, we tend to eat more but feel less satisfied. Try going to bed a little earlier than usual to avoid this imbalance and remember to remove any distractions that might prevent you from nodding off."
I lost my weight by only optimizing my diet. I changed what I ate dramatically and literally melted the weight off. I remember waking up on the fourth day after starting this in complete amazement by the fact that my fingers felt skinny. I’m not sure if it was the amount of salt I ate or what, but my fingers and hands have felt fat for the last year – this alone was enough to keep me going. For the sake of this overview, I will not go into any detail on supplements (as I have yet to learn much about them), and will only briefly touch on exercising. Instead, I’ll focus on optimizing diet for rapid weight loss.
Try out a circuit training program. If you are trying to lose weight quickly for a particular event and don’t care about keeping the weight off, you can try a condensed workout routine. Many women’s and health magazines as well as personal trainers offer similar condensed workout routines designed to maximize weight loss and visible physical slimming within only a few days of beginning the regimen.
Sure, you can lose weight quickly. There are plenty of fad diets that work to shed pounds rapidly -- while leaving you feeling hungry and deprived. But what good is losing weight only to regain it? To keep pounds off permanently, it's best to lose weight slowly. And many experts say you can do that without going on a "diet." Instead, the key is making simple tweaks to your lifestyle.

I am 55 and have been in menopause for 5-6 years, I also had my thyroid removed at 31, So I have a lot of trouble keeping weight off, never mind losing some. I am taking thyroid hormone as well as estrogen and progesterone. What is the best way for me to carb cycle? I feel like you are saying that I should be careful about going to low carb when carb cycling. So keto would be out then, I guess?
About: Laura is a health coach whose passion to help others overcome addiction and gain a satisfying life comes from her own history: For years she battled addiction (to food, cigarettes and many other things) and was taught to believe that as a woman, she was less valuable than a man. Trapped in her own mind and truly miserable, Laura one day realized that the key to overcoming her addictions was to make deliberate choices for every single thing she did — a mindset that taught her just how valuable she is. Now, she’s an extraordinarily strong-willed champion of women’s health who shares her knowledge and expertise with others. A true inspiration on so many levels.
5. Start with one small change. "I realized that a lot of sugar and calories that I consumed came from drinks, so I challenged myself to drink only water—no sugary drinks!—for 30 days. After just one successful week, I decided to add another challenge: to cut back on the carbs I was eating. When I did eat bread, I switched to wheat bread and when I wanted rice, I used brown rice."
About: Amy started her weight loss journey after she ran the Disney Princess Half Marathon at her heaviest weight ever — and realized it was time to make a change. Fast forward a couple years, she's lost 65 pounds, motivated especially by her father, who she calls her “biggest cheerleader.” Then her father passed away, and things went downhill a bit. Amy gained 40 pounds back and in 2014 started a weight loss blog to embark on the ultimate quest: signing up for races (her most recent was the Star Wars Half Marathon) and letting readers know that she feels their pain — and, most importantly, that they can get through it and make the changes and run races, just like she is.
First of all thank you very much for your valuable comment. I am sure you do agree that the Mediterranean diet and Dash diet are not considered as ‘fad diets’ but they are among the healthiest diets to follow with many benefits besides weight loss. As far as the other 3 diets is concerned (17 day diet, slim-fast and dukan diet), they are included in the list because they are better than other commercial diets in many aspects and if followed for a SHORT period of time can generate results.
Tina, that’s awesome. You said some things that rang true for me. At 53 years old, I was exercising plenty, but I love to eat! I was not good at portion control. personally I had to start intermittent fasting. I’ve lost ten lbs in the first few weeks, but have hit a plateau. What I am doing now is going more paleo, modified paleo. I also need to have more discipline in staying the course on exercising, which I love to do, but work often gets in the way. I came across a fitness /diet routine that is one of the most popular in the country , at the moment https://bit.ly/2LTeGBG, looks pretty good. Really it’s not rocket science, although we in the west make it hard. Eat whole foods in moderation, get enough rest, reduce stress, and exercise, not insanely, but regularly. Aerobics and some form of weight bearing exercise seems to be the best combination.
