As with paleo, doing keto for more than a few weeks could lead to nutrient deficiencies according to Andy Yurechko, MS, RD, of Augusta University Medical Center in Georgia . He says lack of fiber is the biggest concern for keto fanatics, who may experience constipation. But it's possible to get fiber by eating lower-carb vegetables like broccoli and chia seeds.
Cordain argues that chimpanzees and horses avoid meat, and they have big bellies that we would have if we didn’t ditch plants for meat. He also says meat increased human brain size, and decreased stomach size so we can have the six-pack abs that chimps can’t. But I looked at his endnotes with citations to research and couldn’t find the source for these theories. I also couldn’t find research showing that legumes and grains were invented by humans.

Foods allowed during the program include meat, nuts, seeds, seafood, eggs, vegetables, and fruits. During the Whole30, participants are advised not to count calories or to weigh themselves. After the program is complete, participants are counseled to strategically reintroduce foods outside the endorsed Whole30 list, document the health consequences and culinary value of these additions, and determine if the addition is desired. The program's founders believe that sugar, grains, dairy, alcohol, and legumes affect weight, energy, and stress levels. Losing weight is not a focus of Whole30; calorie-counting and weigh-ins are not allowed.
The Primal Blueprint: Reprogram your genes for effortless weight loss, vibrant health, and boundless energy by Mark Sisson is a journey through human evolution, comparing the life and robust health of our hunter-gatherer ancestors with a day in the life of a modern family. The author offers a solution in 10 empowering Blueprint Lifestyle Laws: eat lots of plants and animals, avoid poisonous things, move frequently at a slow pace, lift heavy things, sprint once in a while, get adequate sleep, play, get adequate sunlight, avoid stupid mistakes, and use your brain. The reader learns how the right high-fat diet can actually help one lose weight and how popular low-fat, grain-based diets might trigger illness, disease, and lifelong weight gain. The author presents a comprehensive, well thought out paleo style eating plan in a humorous and organized manner. He backs up all his work with research, natural wisdom, and historical timelines. He disputes the role of dietary saturated fat in causation of arteriosclerosis, the role of cholesterol in promotion of heart disease, and the costly over-promotion of expensive, potentially toxic statin drugs. He criticizes our massive overeating of refined carbohydrates and urges avoidance of grains, cereals, bread and sugar. There is specific recommendation for "primal" food including more natural healthy fats and meats, fruits, veggies, and nuts. Some reviewers consider this to be the best of the various paleo books. The many Amazon reviews average to 5 stars. The author's popular and worthwhile web site: Mark's Daily Apple. The 2nd Edition was published January 14, 2012.
Whole30 is a nutritional program designed to change the way you feel and eat in 30 days. Basically, you have to remove all of the potentially inflammatory foods and beverages in your diet (think: added sugar and sweeteners, alcohol, grains, legumes, dairy, processed foods and beverages, baked goods, and junk foods) and eat three "clean" meals a day, made with Whole30-approved ingredients (think: meats, seafood, veggies, and eggs).
The Soft Science of Dietary Fat is a summary of an article in Science Magazine reporting that mainstream nutritional science has demonized dietary fat, yet 50 years and hundreds of millions of dollars of research have failed to prove that eating a low-fat diet will help you live longer. In fact, there are good reasons to believe high-carbohydrate diets may be even worse than high-fat diets. Here is the text from the original article by Gary Taubes.
Plus, I feel like the way I eat directly affects my mood. If I eat sugar, I almost always feel like garbage. If I eat protein and veggies and tons of avocado, I feel stable and much less like I am going to have a stage-four meltdown. Blood sugar swings are also real — no one wants to deal with me when I am hangry. It’s a nightmare. This program is supposed to help with all these things. I desperately wanted to feel better, so I dove in.
Generally speaking, dieters are advised to eat between 20-30 grams of carbohydrates per day in order to maintain ketosis. To put this into perspective, a quarter cup of steel cut oats has 29 grams of carbs and a banana has roughly 27 grams of carbs. So if you have a few bites of oatmeal or a small piece of fruit, whoops! That's your carb intake for the day.
Paleo diets are based on a simple premise – if the cavemen didn’t eat it, you shouldn’t either. So long to refined sugar, dairy, legumes and grains (this is pre-agricultural revolution), and hello to meat, fish, poultry, fruits and veggies. The idea is that by eliminating modern-era foods like highly-processed carbs and dairy, you can avoid or control “diseases of civilization” like Type 2 diabetes and heart disease, and likely lose weight too. What you eat and how much depend on your goals or the specific program you’re on, if you choose to follow one. The high-protein diet is ranked poorly among U.S. News experts, who consider it too restrictive to be healthy or sustainable.
Transformed cells adapt metabolism to support tumor initiation and progression. Specific metabolic activities can participate directly in the process of transformation or support the biological processes that enable tumor growth. Exploiting cancer metabolism for clinical benefit requires defining the pathways that are limiting for cancer progression and understanding the context specificity of metabolic preferences and liabilities in malignant cells. Progress toward answering these questions is providing new insight into cancer biology and can guide the more effective targeting of metabolism to help patients.
