Curiously, this study was funded by the Nutrition Science Initiative (NuSI), a group with the aim of producing “conclusive results in the next decade” in a sometimes confusing nutritional landscape. They claim our nutritional guidelines are “based on inconclusive science,” and though their website doesn’t directly indicate any bias, their research so far focuses on the effects of carbohydrates on obesity. This was the second published study that received funding from the institute. In the first study, published in the American Journal of Clinical Nutrition in 2016, researchers hypothesized that a low-carbohydrate diet increased energy expenditure. Results said otherwise:
So I was following a ketogenic plan for the past month in an effort to lose about 4-5% body fat and try to turn down the inflammation in my body to help with my hashimotos and psoriasis. I don’t eat meat, so it was ALOT of eggs (from the farmers market), primal mayo, wild caught salmon and cold smoked lox (vital choice), brain octane oil, coconut oil, avocado oil with VERY little carbs…like 85% fat, 10% protein and 5% TOTAL carbs. I was eating about 1100-1200cal per day and BELOW 18g TOTAL carbs…Couldn’t get above .6 in AM fasted blood ketones or below 80 fasted blood sugar. I do 90min of Ashtanga yoga (primary and half of second series) 5 days a week and 20-30min weight/HIIT style workouts about 3-4 days per week (Kettlebell, jump rope, plyometrics and free weights). I take Concentrac Trace Minerals along with my d3/k2, l-carnitine, l-glutamine, forskollei, green pastures butter/cod liver oil and probiotics. I have been at the Bulletproof Conference this weekend and I bought the new Bulletproof exogenous Ketones to try.

Thank you for this article as it cleared up a bunch of stuff for me. I started trying to get into ketosis back in August and lost 20lbs in about 6 weeks. Then it all stopped but had another 20lbs I wanted to loose. I had a hard time staying in ketosis and gave up about a week ago with the holidays approaching. Anyways I glazed over all the technical and science facts as it makes my head spin and might of missed it but my only question is what is the food portion of the diet like? The drinks are the easy part, do you have a diet plan that is good for someone that hits the gym hard 4-5 days a week for and hour and half. 45 min weights and 30-45 min cardio? It’s what I struggle with most the food and what attracted me to a ketogenic diet in the first place is eating 1 or 2 meals a day and being satisfied.
I’ve been on and off of my Keto diet with the primary purpose of losing weight. I’m 30 years old, workout daily – I’m in decent shape but have some extra fat around the mid-section that I’d like to get rid of, I am hoping to lose ~20 pounds of fat. However, the problem is that I am an extremely picky eater with tremendous cravings for some of my favorite carb-heavy foods – I only eat a number of high-fat / low-carb foods that help me attain Ketosis, so cycling through them multiple times a week becomes excruciating. I find myself cheating on my diet every 2 – 3 weeks, which causes a 3 – 5 pound setback that takes me a few days to overcome and get back into ketosis.
Great read! I have been on and off Keto for over a year. I lost weight, but every time I try to add in carbs my weight spikes back up. Keto is not long term sustainable, and because of it’s fast results, it didn’t teach me how to live a healthier lifestyle. Now I am on no particular diet, using portion control and regular exercise and I feel better than I have in years. Thanks for this – I needed to hear it!
That said, I think the biggest changes are the result of me dropping the sugars and breads. Tracking my eating and being more conscious about my foods has made a difference. I definitely plan to keep on this track for a while and slowly work towards a fuller keto-adapted diet/body. I’m not going with the “all-in” that some recommend, cutting out all artificial sweeteners and such, though I have limited them. I’m not really tempted to indulge in the sweets that have been tempting in the past.
I originally started this “diet” because I am the Maid of Honor in my best friends wedding. She made me order a size down than I was comfortable with and it fit, if you didn’t zip it up. I tried it on a couple weeks later and it REALLY didn’t fit, I couldn’t pull it up past my hips. I was mortified and super embarrassed, how was I going to be in this wedding if I can’t even fit in this dress. Cut to now, I just tried on my dress and it’s too big! I’m so excited that I have to get it altered.
Josh Axe, a doctor of natural medicine and clinical nutritionist, estimates that about 25% of people who try a ketogenic diet experience these symptoms, with fatigue being the most common. “That happens because your body runs out of sugar to burn for energy, and it has to start using fat,” he says. “That transition alone is enough to make your body feel tired for a few days.”
Gut health is extremely important for anyone looking to lose weight and increase overall health[*][*]. It is not uncommon for those who shift to a ketogenic diet to have a change in the production of bacteria in their colon (although not necessarily a bad thing – just a change)[*]. To help support this change and increase the healthy bacteria in your gut, try consuming more fermented foods such as sauerkraut, kimchi or kefir and/or supplement with a high-quality probiotic[*][*].
