Ketogenic Diet vs. Low Carb Diet: Thomas DeLauer-
Ketosis to Help Your Business? http://www.ThomasDeLauer.com/life-fitness-coaching
-Ketosis is when your body turns to fat rather than carbohydrates for energy. Ketosis can occur during fasting, when you reduce the amount of carbs or calories in your diet, during pregnancy or after exercising for a long period of time. Many diets use ketosis as the means of burning fat while maintaining muscle – examples include the Atkins diet and other low-carb diets. This strategy can also lead to decreased hunger. How long does it take to kick your body into fat burning, ketosis mode? Roughly 3-4 days of consuming less than 50 carbs per day, the equivalent of 2 bananas. Benefits include weight loss, seizure prevention, cardiovascular health and type-2 diabetes help, to name a few.
How does it Work? When glucose is in short supply, your liver will break down fats into ketones, which are then used throughout your body for energy. Muscles and other tissues in your body use ketones rather than glucose for energy metabolism. In a healthy person, the production of ketones for energy is the body’s natural response to starvation, so this happens when dieting, overnight and during fasting.
Glucose or Ketones: Which is More Effective? Many brain diseases, such as epilepsy, are already being treated by the ketogenic diet. The mechanisms to why it helps the brain are still being studied, but there are some possible reasons that ketones seem to be a good energy source for the brain. One major Ketone, beta-hydroxybutyrate, or BHB, provides more energy per unit of oxygen than glucose, and thus may be even more efficient than glucose at providing energy to the brain. (3)
-The ketogenic diet has also been found to increase the number of mitochondria in brain cells. In a 2004 study on rats, one group was fed a ketogenic diet while the other was fed a normal diet. A positive impact was found on the gene expression for mitochondrial enzymes in the hippocampus, the memory and learning center of the brain. (4)
Ketosis and Body Water Composition: High fat and low carb diets are known to lead to fast weight loss. The fast weight loss is due to water weight being shed (5)
-When you decrease carbs, you decrease water storage in the body.
Who Can Benefit From Ketosis? If you are looking to shed some body fat, ketosis may be a good tool. This can go along with an exercise regimen as you maintain muscle while losing fat. Ketosis can also benefit those who need to boost brain power as energy may be utilized more effectively in the brain.
*Be careful because those with diabetes can get too high of a level of ketones in their blood, which is very dangerous. This occurs due to the low levels of insulin in the blood, which will signal the body to produce excess ketones that will build up in the blood, making the blood pH too low.

Learn the 3 Safest fish to eat! I’ll teach you more at http://www.ThomasDeLauer.com
We are going to go over the top 3 fish to eat and the fish that you may want to avoid. Fish can become contaminated in a number of ways – size, species, age and location determine contamination levels. Heavy Metals: Mercury and Lead-
Mercury is known to cause many health problems and is especially dangerous for children and women who are or may become pregnant. It can take 12-18 months for mercury to pass through the body, so women who may become pregnant should also work hard to avoid mercury. The nervous system and kidneys are the main targets of mercury. Children exposed to mercury may cause mental development problems, including coordination and learning handicaps. Anyone can experience mercury health effects, including: fatigue, dizziness, numbness or tingling, memory and coordination problems, irritability.If enough mercury is consumed, permanent brain and kidney damage can occur. Large, older, or predatory fish have more time and eat more contaminated foods, allowing heavy metals to bioaccumulate.
Industrial Chemicals-
PCBs, dioxins, DDT and other chemicals can leach from factories or garbage into our waters. These chemicals are related to cancer risk. Bottom dwelling fish are the most susceptible to these toxins, including the American eel, sea trout and wild striped bass.
Radiation-
The Fukushima nuclear disaster is one of the most widely discussed radiation events that has an impact on what we eat. Radiation is known to cause cancer, so avoiding foods high in radioactive compounds is important. Researching your fish choices online is the best way to avoid consuming fish that come from an area high in radiation.
Choosing Fish for Your Family-
The Environmental Defense Fund Seafood Selector is a great benefit when deciding what fish to avoid and what fish to load up on. Given the above concerns while also weighing in health and deliciousness, here is the list of the top three fish:
(1) Pacific Sardines (US and Canada):
-Low in mercury
-Sustainably fished
-High in omega-3 fatty acids, vitamins B12, B2, B3, D, selenium, phosphorus, calcium, copper and more
-They are inexpensive and easy to find canned.
(2) Wild Alaskan Salmon:
-Salmon is one of the most delicious fish, rich in healthy fats.
-Low in mercury and sustainably fished
-Contains bioactive peptides that may support for cartilage, insulin and inflammation.
-High in vitamins B12, B3, D, selenium, omega-3 fatty acids, phosphorus, B6 and many others.
(3) Muscles:
-Low in mercury and one of the most sustainably fished seafood sources out there
-High in selenium, omega-3s, B12, iron, magnesium, potassium, phosphorus and many others.
Seafood to Avoid:
Due to toxins and sustainability, it is best to stay away from these types of seafood.
(1) Shark:
-Anything this high up on the food chain is going to be a red flag when it comes to toxins.Predators consume other fish and their toxins. The higher up on the food chain, the higher the levels of mercury and toxins in the fish. Adding to the health dangers is the unsustainable fishing practices. Sharks have long gestation periods, taking a long time to mature and have offspring. This makes overfishing or depleting their numbers easy to do. Most shark species are experiencing a large decline due to fishing, being caught as bycatch and for fins in Asia.
(2) Tuna:
A favorite among many sushi goers is unfortunately very high in mercury and horrible for sustainability.
Some tuna is much better for you and the environment than others. If you do consume tuna, US yellowfin is the best option. Canned albacore tuna is high in mercury and should be avoided. Bluefin and imported albacore are the worst tuna options for health and sustainability – do your best to avoid these.
Canned light tuna is better for you than canned white tuna when it comes to mercury, with about ⅓ the mercury content of canned white tuna.
(3) Farmed Tilapia:
Farmed tilapia in the US is often imported from China and Taiwan where the conditions and chemicals used are very troublesome.
(4) Swordfish:
All swordfish, being large hunters, are high in mercury. They are also fished very unsustainably, with large bycatch of sea turtles, sharks and seabirds.

Best Meats to Eat | Low Carb High Fat Diet | Protein Fatty Acids Comparison (Meat Analysis)
Notable Fats: Linoleic and low content of stearic.
Bison-
Calories: ~145
Fat: 7.2 g
Saturated: 2.9 g
Monounsaturated: 2.8 g
Polyunsaturated: 0.3 g
Omega 3: 38 mg
Omega 6: 261 mg
6 to 3 ratio: 6.9 : 1
Notable Fats: Stearic and linolenic.
Pork-
Calories: ~260
Fat: 21 g
Saturated: 7.9 g
Monounsaturated: 9.4 g
Polyunsaturated: 1.9 g
Omega 3: 70 mg
Omega 6: 1670 mg
6 to 3 ratio: 23.8 : 1
Notable Fats: Oleic and palmitic acids.
Monounsaturated Fats:
Monounsaturated fat molecules are not saturated with hydrogen atoms – each fat molecule has only the space for one hydrogen atom.
Oleic Acid – Monounsaturated Fat
Oleic acid benefits the myelin sheath as it’s one of the most common fats in myelin.
Oleic acid regulates the activity of adrenoceptor signaling pathways which direct the adrenergic receptors (α- and β-adrenoceptors) that help regulate blood pressure.
Oleic acid can also increase fat oxidation as it increases the expression of genes involved in fat burning.
Specifically, oleic acid stimulates the cAMP/protein kinase a pathway and activates the SIRT1-PGC1α transcriptional complex to modulate rates of fatty acid oxidation.
Polyunsaturated Fat:
In polyunsaturated fats, there are a number of spaces around each polyunsaturated fat molecule – they are not saturated with hydrogen atoms.
Alpha Linolenic Acid – Polyunsaturated:
ALA is an omega 3, but it’s a precursor to EPA and DHA – the conversion rate in our bodies is extremely low – often less than 1% of ALA is converted to EPA and DHA.
Omega 3 vs 6 Overview – Polyunsaturated Fat:
Eicosapentaenoic acid (EPA) – main function is to produce signaling molecules called eicosanoids, which help reduce inflammation.
Docosahexaenoic acid (DHA) – important for healthy brain development and function.
Most common omega 6 is linoleic acid (LA) – LA is either burned as energy or converted into longer omega-6 fats such as arachidonic acid (ARA.)
Saturated Fat:
Stearic Acid – Saturated Fat-
Stearic acid ingestion rapidly and robustly causes mitochondrial fusion in people. When stearic acid levels are low, the Transferrin Receptor TfR1 activates JNK signaling, leading to ubiquitination and inhibition of Mitofusin 2 and hence mitochondrial fragmentation and reduced oxygen consumption. In the presence of stearic acid, the fatty acid molecule is covalently attached to TfR1 via a thioester bond in a post-translational modification called stearoylation, analogous to protein palmitoylation by palmitic acid. This leads to reduced JNK activation by TfR1, to mitochondrial fusion, and to elevated oxygen consumption. So stearic acid stearoylates TFR1, thereby inhibiting its activation of JNK signalling – this leads to reduced ubiquitination of mitofusin via HUWE1, thereby promoting mitochondrial fusion and function.
Palmitic Acid – Saturated Fat:
Palmitic acid has historically been depicted as ‘unhealthy, but a review published in Frontiers in Physiology looked at the role it plays in human health. Palmitic acid has a critical role in cellular membrane functionality by affecting their ‘flexibility’ and permeability and it forms reversible links to cell membrane proteins.
Conjugated Linoleic Acid – Trans Fat:
Conjugated linoleic acids are polyunsaturated fatty acids containing both cis- and trans- bonds as well as double bonds. The CLA cis-9, trans-11 is mostly found in foods, whereas trans-10,cis-12 is found in supplements.

Keto Diet vs. Paleo Diet: Which Diet is Healthiest for You- Thomas DeLauer… The idea behind the Paleolithic diet is to replicate the ways that our ancestors ate; ancestors could only hunt and gather – had little access to grains and no access to processed foods. The ketogenic diet is designed to completely alter your internal state, a state in which your body burns fat. The Keto diet was originally developed for disease management and to this day is being used for conditions such as epilepsy.
So, a paleo diet, just like a keto diet, focuses on getting fat and protein as a primary source of energy. However, the big difference is paleo doesn’t avoid carbs. While both diets came about for different reasons, they are both used (mainstream-ly) as effective tools for weight loss.
Similarities – Health Benefits
In addition to noticeable weight loss effects, collective studies from the European Journal of Clinical Nutrition, Journal of Internal Medicine, The Journal of Clinical Endocrinology & Metabolism, and the New England Journal of Medicine have found that both Paleo and Keto diets are effective at reducing triglycerides, blood pressure, blood sugar and insulin levels (1,2,3,4)
Despite providing similar health benefits, they do have some key differences.
Key Differences:
Carbs, Fats and Glucose- The main difference is that a Keto diet is truly low carb, whereas a Paleo diet is not necessarily low carb – paleo relies on glucose and keto relies on ketones
A keto diet requires you to adhere to a strict macronutrient ratio (75% fat, 20% protein, 5% carb) The paleo diet still utilizes glucose for much of its energy so carbs are still a big part of the diet. In order to be in ketosis and utilize ketones, your body needs to be starved of glucose, which results in the body burning fatty acids that produce ketones; an alternative source of energy to glucose. Ketosis is a state that you have to achieve, paleo is about avoiding certain food groups. So a paleo diet is a little more forgiving as having too much of one macro or another won’t kick you out of a metabolic state, unlike keto.
Dairy:
The Paleo diet removes foods that are hard for the body to break down and can wreak havoc on gut health — dairy products are one of them. Keto dieters often eat dairy products because they’re high in fats while also being low in carbohydrates.
Artificial Sweeteners/Food Quality:
The Paleo diet cuts out most processed food, especially ones with artificial sweeteners and additives – focuses strongly on choosing whole foods that are nutrient-dense, high-quality, and free from toxins. However, on the Keto diet the only requirements are that your food is low-carb/high fat. This means diet soda is technically Keto approved and so are other artificially sweetened low-carb junk foods – Although a healthy Keto diet should also include high quality food, it isn’t the emphasis. Summed as short as possible – No processed foods vs no carbs (5)
Paleo and CrossFit:
Carbs are staples for CrossFit and athletes, but they are somewhat restricted in the Paleo diet. The Paleo diet also eliminates grains and legumes (both key carb sources for athletes), as well as dairy, salt, and vegetable oils. Carbs that are allowed on the paleo diet (no grains, for example) are too low on the glycemic index to replace glycogen mid- and post-run as quickly as endurance athletes typically need. You’re not low enough on carbs to be producing ketones so you’re not using fat as a main source of energy, and not high enough on carbs to be receiving enough energy from them (6)
