Current Hunter-Gatherer Diets | Center for Academic Research and Training in Anthropogeny (CARTA)
Short version: Our best guess at a paleo diet comes from asking modern hunter-gatherers on the savannah what they eat. Which is still indirect evidence of paleolithic diets, for the record: While the Hadza are the experts on wild foods of the savanna, hunter-gatherers are no more static than anyone else. As a contemporary people, the Hazda’s hunted-and-gathered diet is modern, not paleolithic.

Abstract: The diet composition of hunter-gatherer populations continues to be implicated in the reconstruction of dietary models and social behavior of early members of the genus Homo. Diet has been linked to the evolution of the enlarging hominin brain, the sexual division of labor, routine food sharing, cooperative breeding, and family formation. Despite this significance, few quantitative studies are available; the cross-cultural data used for many of the reconstructions remains anecdotal and was not collected systematically across populations. Here, I report data on the diet composition and foraging profiles of the Hadza hunter-gatherers of Tanzania. Hadza plant foods were analyzed to determine the energy values (kilocalories), content of fat (lipid), crude protein (CP), free simple sugars (FSS), fiber (neutral-detergent fiber - NDF), total non-structural carbohydrates (TNC), and ash. The significance of meat, tubers, and honey is addressed and the role that these food items play in evolutionary models is explored.

8 Muscle Gaining Mistakes - Men Over 40 (FIXED!!) - YouTube
(1) Start with the Warm-up, get body ready to train. Get your heart rate up. Break a sweat.
(2) Focus on building strength. Do so responsibly. Controlled strength is the focus. Commend the weight that you use. Pause reps for bench press and squats. Progressively overloading.
(3) Train the mind-muscle connection. Pursuit of the quality of each repetition. Introduction of joint stability and muscular control.. Now feed more into controlled strength.
(4) How to string quality reps into quality sets and a quality workout? Introduce metabolic training. Lighter weights on exercises and going for the burn (metabolic stress). Get THROUGH the burn.
(5) Train like an athlete. Be scientific, be purposeful. Doing athletic things. E.g. Jumping. Don't be one dimensional.
(6) Boring corrective exercises. Face-pulls.
(7) What type of cardio? Do sparing cardio. Battle ropes, sled push, Farmers carry,
(8) Nutrition and supplementation. Our metabolism changes. Reliance on consistent, high quality nutrition. Be on point with your nutrition. Focus on increasing consistency of diet.

How exactly does fat cause cancer?
July 22, 2019 | The Globe and Mail | by PAUL TAYLOR.

our understanding of fat has gone through a huge transformation in recent years.

It was once thought that fat – medically known as adipose tissue – was just an inert collection of cells used for the storage of surplus calories, or energy, that we can draw upon in times of need.

But now medical experts realize that fat behaves almost like an organ – interacting with other parts of the body. It actually sends out signals that play a crucial role in regulating metabolism, the immune system and other functions. If we become overweight or obese, the normal running of the body can get knocked off balance by too many signals from fat.

There are several ways in which fat may contribute to the development of a variety of cancers:

(1) fat can be converted to estrogen – a hormone that is known to fuel the growth of some ovarian, endometrial (the membrane lining the uterus) and breast cancers.

(2) Fat also creates a state of chronic inflammation – another factor linked to cancer. The inflammatory process is associated with free radicals, unstable oxygen molecules that can damage DNA and cause potentially cancerous genetic mutations.

(3) excess weight often leads to a condition known as insulin resistance. Insulin is a hormone that moves glucose (or sugar) from the blood stream into cells where it is used for energy. As the body’s cells become resistant to insulin, the pancreas responds by producing more and more of the hormone in an attempt to clear glucose from the bloodstream. Elevated levels of insulin and related substances – such as insulin-like growth factor-1 – stimulate cells to divide and multiply. This increased activity may lead to random genetic mutations that set the stage for cancer.

(4) People with excessive weight around the abdomen are prone to gastric reflux (or heartburn), in which digestive juices will back up into the tube connecting the mouth to the stomach. The constant irritation can damage cells and may lead to esophageal cancer.

(5) Dietary and lifestyle factors that may contribute to weight gain are also directly linked to an increased cancer risk. For example, diets rich in red meats and highly processed foods have been implicated in colorectal and other cancers.

People who tend to eat lots of fresh fruits and vegetables and whole grains are consuming a host of micronutrients that may help guard against cancer. Likewise, studies suggest that regular exercise may be protective, too.
