Our bodies normally run on glucose or sugar for energy, but we cannot make glucose ourselves and only store about 24 hours worth within our muscles and liver. Once glucose from carbohydrates is no longer available for energy due to following a low-carb diet, we begin to burn stored fat for fuel instead. This is why low-carb diets often lead to fast weight loss and other metabolic improvements within a relatively short period of time.
Another downside: If you have had chronic health issues (especially gut related), you may find that reintroduction actually teaches you that you're sensitive to most foods. It turns out peanut butter, gluten, and most dairy are now off limits. That rots!! But I'll live. I feel so, so much better without them, as I learned. And wouldn't you rather know why you feel crappy all the time?
You made me smile with the food leper reference. Love it. As for snacks, there is a page here and here to look at and here is my snack finder. Boiled eggs, avocados, pork crackling, nuts, fat bombs, calamari, granola bars, cold meats … I hope these give you some ideas. Eventually the goal is to stop snacking, but in theme time, these might help you out.
When researchers from the Discipline of Psychiatry and School of Medicine at the University of Adelaide compared the hormonal and psychological effects of a low-protein, high-carbohydrate (LPHC) diet and a high-protein, low-carbohydrate (HPLC) diet in women with a hormonal disorder called polycystic ovary syndrome (PCOS) over the course of 16 weeks, they found a significant reduction in depression and improvement in self-esteem in those on the low-carb diet.

For instance, the fat allowance of the diet may be problematic. “My biggest hang-up with the paleo diet is all of the saturated fats it promotes with all of the meats,” explains Holley, noting that you could look for a locally sourced meat, whose origin and method of raising you're aware of, as a healthier option. Saturated fat from meat has been linked with an increased risk of early death. (9)
At The Clean Slate Cafe, our Whole30 Approved partners Applegate, Spindrift Sparkling Water, Kettle & Fire Bone Broth, Primal Kitchen, Chomps, and Primal Palate collaborated on The Clean Slate Cafe, our completely Whole30 compliant pop-up restaurant. They served Whole30 meals to over 1500 guests in NYC over the course of 3 days! Enjoy this little peek into the opening night party. The Clean Slate Café is a testament to the fact that when our partners come together to serve our community, incredible things happen. What #Whole30Approved collaboration would you love to see?
Jan Engvald has studied food and health thoroughly in the literature. In Unexpected facts on... food he shows that today's health advice (more or less unchanged for more than 30 years) is a direct cause to the increase in national diseases like coronary heart disease, stroke, cancer, obesity, adult-onset diabetes, allergy, eye diseases, etc. His findings are low-carb and high-fat, close to paleo, though he allows high fat dairy.
By eliminating carbohydrates from the diet and keeping the body’s glycogen stores low or almost empty, we can prevent insulin from being released and storing fat. Less insulin circulating around our bloodstream means that the body is forced to use up all of its glycogen stores, then reach into fat stores tucked away in our adipose tissue (body fat) for ongoing fuel.
In making the case for meat, Cordain presents anecdotal evidence of Eskimos who lived their full life without a heart attack. The Eskimo diet consists of 97% meat, which he concedes causes all Eskimos to develop atherosclerosis—a common precursor to heart disease. But Cordain says Eskimos never die of heart disease. He discusses one Eskimo who lived 45 years and another who lived 53 years, both without heart disease! He then jumps to the conclusion that because these Eskimos didn’t get heart attacks, even with severe atherosclerosis, meat must have protected them from heart disease. So Cordain’s best case for lots of meat is that you can live to the ripe age of 45 or even 53 without a heart attack. But do people—even unhealthy smokers or the obese—generally get heart attacks before age 53?

The Amazon reviews average to 4+ stars.
Then don’t give up the fruit! Go for it. You sound like a fit and active person within the normal weight range. Generally the advice is to stay off excessive fruit, and high sugar fruit especially if people are overweight or have other health issues, then in that case fruit is not your friend. But with everything, eat within your personal carb limitations and eat to what is appropriate to you. Whole fruit is somewhat self limiting due to the fibre and water anyhow. You obviously have worked out a fabulous routine and it is working, so why change, stick with it Tom and enjoy 🙂
With funding from the Laura and John Arnold Foundation, in 2012 Taubes co-founded the Nutrition Science Initiative (NuSI), with the aim of raising over $200 million to undertake a "Manhattan Project for nutrition" and validate the hypothesis. Intermediate results, published in the American Journal of Clinical Nutrition did not provide convincing evidence of any advantage to a low-carbohydrate diet as compared to diets of other composition – ultimately a very low-calorie, ketogenic diet (of 5% carbohydrate) "was not associated with significant loss of fat mass" compared to a non-specialized diet with the same calories; there was no useful "metabolic advantage". In 2017 Kevin Hall, a NIH researcher hired to assist with the project, wrote that the carbohydrate-insulin hypothesis had been falsified by experiment. Hall wrote "the rise in obesity prevalence may be primarily due to increased consumption of refined carbohydrates, but the mechanisms are likely to be quite different from those proposed by the carbohydrate–insulin model".

In fact, the health benefits of the paleo diet are unproven. "Our ancestors ate this way and didn't have many of the chronic diseases we do, but that doesn't mean the food they ate is the reason why; drawing that conclusion would be like saying we live three times longer than our Paleolithic ancestors because we eat fast food," says Christopher Ochner, MD, research associate at the New York Obesity Nutrition Research Center at St. Luke's and Roosevelt Hospitals. Still, a handful of small studies have tried to determine if a paleo diet is a healthier diet. One small study published in the journal Diabetologia found that the diet improved blood sugar over 12 weeks compared to a Mediterranean one that allowed grains, low-fat dairy, and oils, but it's hard to say whether researchers would come to the same results in a larger study.
Saturated fat has been demonized by our health authorities and media. What is the basis for this position on Saturated fat? Are current recommendations for VERY low saturated fat intake justified? How much saturated fat (and what types), if any should one eat? Without a historical and scientific perspective these questions can be nearly impossible to answer.
