Why Is Eating An All Meat Diet Bad For Your Health And Body?
I have this coworker who is a passionate 21 yr old, who is convinced that eating an all meat diet is the best for your body and health. It is absolutely crazy, so if lots of people would respond with legitimate scientific/health reasons why not, that would be awesome!!! 
The AMA and the ADA discourage diets like the Atkins because of their long-term health risks.
“It’s so high in cholesterol and fat and total fat — the opposite of what all the health organizations, from the American Heart Association to the American Dietetic Association, recommend… and is also low in fruits and vegetables and whole grains’ — foods with proven health benefits. While some of the vitamins and minerals in these foods can be obtained through supplements, other benefits — like fiber or phytochemicals — can only be found at the source.”
Furthermore, a high protein diet doesn’t work unless you stay on it forever.
“[Rosenbloom ] notes that ‘in my 25 years as a dietitian, I’ve never met anyone who’s kept the weight off.’ She said boredom with the no-carbohydrate regimen (which eliminates breads and pastas and ’starchy’ fruits and vegetables) usually causes dieters to abandon the diet, at which point ‘they gain all the weight back — and more.’”http://www.atkinsexposed.org/atkins/97/D…
High protein diets have been linked to increased risk for cancer, heart disease, kidney failure, hypertension pressure, and osteoporosis, among other things. All this information is available in the medical literature.
Too much fat and protein, not enough carbohydrates. Saturated fat is bad because it can raise cholesterol and clog your arteries. Too much protein can be toxic and harm your liver and kidneys. You will miss out on vitamins found in carbohydrates and vegetables which are not found in meat.
You must have correct information if you want to lose weight. You can use program that I lost 21 pounds in 35 days. It works just amazing and It will work for you too. You can find more information here link below.
It will clog his heart and colon. Meat is actually bad for you. Unfortunitly it is nearly impossible to get the proper nutrition with out it. Vegetarians say they are getting all they need but they are not.
The only exception to the rule that you need to include a carbohydrate source is the Mongolian claim that they can live long periods on horse meat and blood. I don’t even know if it’s really done.
meat= not good for health
meat= cholestrol, saturated fat
meat- usually served with fatty sauces and dressings
meat= not encouraged by mther earth
you need some of everything. just like how eating an all vegetarian or vegan diet is just as crazy and unhealthy.
Actually an all meat diet is used for execution in the middle east.
Meat is high in saturated fat and cholesterol.
If your coworker is eating a high fat diet (>65% calories from fat) then I think an all meat diet is boring but fine. Protein & fats are essential to health, carbs are optional. The body can manufacture all it needs from the protein/fat combination.
The body needs sufficient fuel calories for energy. Fuel calories can be from carbs OR fat but shouldn’t be from protein. Protein is required for tissue needs & cellular regeneration but it shouldn’t be used for fuel calories for energy. Protein is not only an inefficient fuel (only 58% can be converted to glucose) but the byproducts of gluconeogenesis (nitrogen & ammonia) can overwhelm the body & large amounts long term can cause major health problems.
A low carbohydrate diet is a high fat diet. The protein should only be a little higher than adequate. Although it is completely possible to live on a fat/protein only diet for long term (as proven by research done in a hospital setting) it becomes boring fairly quickly. Luckily many vegetables & some fruits, nuts & seeds are low in carbs and greatly expand the diet. Most long term low carbers eat as many, if not more non starchy vegetables than vegetarians.
Glucose is the bodies preferred fuel (if you want to get technical, it actually burns alcohol most efficiently, but that doesn’t make it any healthier for the body than carbs), the body can convert 100% of carbs, 58% of protein & 10% of dietary fat into glucose. The body can also be fueled by fat (dietary fat & fat cells) but only in the absence of carbs. Your brain actually prefers (* reference info) to be fueled by ketones (part of the fat burning process), only the heart requires glucose, but glucose can be easily converted from fat stores or excess protein if needed or dietary fat.
IF a person eats sufficient fat & protein & minimal carbs, they can become very healthy. Free of blood sugar health problems, high blood pressure, health problems associated with high cholesterol, obesity health problems. (Cancer is fueled by glucose, if your body is not fueled by glucose, it doesn’t seem to be possible to have cancer, but that is just speculation) Anything less that 9 grams of carbs per hour controls insulin and is considered low carb (up to 144 grams per day).
High fat, adequate protein and very low carbs will after 3 days convert your body from glycolysis (burning glucose for fuel) to burning fat (dietary & body fat) as fuel (ketosis). While in ketosis you will burn dietary fat and if dietary fat is more than sufficient, body fat directly. High calories will keep the metabolism at maximum fat burning capabilities. During this time the body will go through carb withdrawals, but by the 4th day you will be free of sugar addictions. The first week or so of this conversion process a person feels weak, sluggish, headachy but after this is over, most comment that they feel better & have more energy than ever before. They eat foods for nutrition & fuel & their bodies crave vegetables & fruits.
Metabolism is controlled by nutrition. You can’t eat 600 or 2000 calories of fruit, your body will treat it as being starved (which it is, starved of nutrition) & will shut down your metabolism as if you’re eating nothing, but will store every possible ounce as fat. You may lose water weight & lean tissue the body strips for nutrition, but that makes fat storage more efficient. Inversely, you wont gain weight on 5000 or more calories of fat & protein (if fat is 65% of calories) because insulin (the fat storage hormone) is not activated.
Plaque build up in the arteries are more attributable to carb consumption than dietary fats, which is the conclusion of the following study. Carb consumption raises triglycerides & VLDL (bad cholesterol). Fats raise the HDL (good cholesterol). High triglyceride levels & low HDL levels are an indicator of plaque, glycation – the precursors to a heart attack and heart disease.http://heartscanblog.blogspot.com/2009/1…
study from the Oxford group examining the postprandial (after-eating) effects of a low-fat vs. low-carbohydrate diet. (Roberts R et al, 2008
Postprandial lipoproteins, you’d think, would be plentiful after ingesting a large quantity of fat, since fat must be absorbed via chylomicrons into the bloodstream. But it’s carbohydrates that figure most prominently in determining the pattern and magnitude of postprandial triglycerides and lipoproteins. Much of this effect develops by way of de novo lipogenesis, the generation of new lipoproteins like VLDL after carbohydrate ingestion.

The brain gets its energy from ketone bodies when insufficient glucose is available. After blood glucose is lowered for 3 days, the brain gets 30% of its energy from ketone bodies. After 40 days, this goes up to 70% (during the initial stages the brain does not burn ketones, since they are an important substrate for lipid synthesis in the brain). In time the brain reduces its glucose requirements from 120g to 40g per day.
