E-Articles - Top 15 Reasons to Avoid Low Carb Diets
Low carb (carbohydrate), high protein diets are the latest
dieting craze. However, before you jump on the band wagon,
you may want to consider a few things:
1. Low carb (ketogenic) diets deplete the healthy glycogen (the storage form of glucose) stores in your muscles and liver. When you deplete glycogen stores, you also dehydrate, often causing the scale to drop significantly in the first week or two of the diet. This is usually interpreted as fat loss when it’s actually mostly from dehydration and muscle loss. By the way, this is one of the reasons that low

popular at the moment - there is a quick initial, but deceptive
drop in scale weight.
Glycogenesis (formation of glycogen) occurs in the liver and muscles when adequate quantities of carbohydrates are consumed - very little of this happens on a low carb diet.
Glycogenolysis (breakdown of glycogen) occurs when glycogen is broken down to form glucose for use as fuel.

oportion to the rate of depletion of muscle glycogen. Bottom
line is that you don't feel energetic and you exercise and move
less (often without realizing it) which is not good for caloric
expenditure and basal metabolic rate (metabolism).
3. Depletion of muscle glycogen leads to muscle atrophy (loss of muscle). This happens because muscle glycogen (broken down to glucose) is the fuel of choice for the muscle during movement. There is always a fuel mix, but without muscle glycogen, the muscle fibers that contract, even at rest to maintain muscle tone, contract

glycogen also causes you to exercise and move less than
normal which leads to muscle loss and the inability to
maintain adequate muscle tone.
Also, in the absence of adequate carbohydrate for fuel, the body initially uses protein (muscle) and fat. the initial phase of muscle depletion is rapid, caused by the use of easily accessed muscle protein for direct metabolism or for conversion to glucose (gluconeogenesis) for fuel. Eating excess protein does not prevent this because there

deficit.
When insulin levels are chronically too low as they may be in very low carb diets, catabolism (breakdown) of muscle protein increases, and protein synthesis stops.
4. Loss of muscle causes a decrease in your basal metabolic rate (metabolism). Metabolism happens in the muscle. Less muscle and muscle tone means a slower metabolism which means fewer calories burned 24 hours-a-day.
5. Your muscles and skin lack tone and are saggy. Saggy muscles don't look good, cause saggy skin, and cause you to lose a healthy, vibrant look (even if you’ve also

6. Some proponents of low carb diets recommend avoiding carbohydrates such as bread, pasta, potatoes, carrots, etc. because of they are high on the glycemic index - causing a sharp rise in insulin. Certain carbohydrates have always been, and will always be the bad guys: candy, cookies, baked goods with added sugar, sugared drinks, processed / refined white breads, pastas, and rice, and any foods with added sugar.
These are not good for health or weight loss.

The effect of high glycemic foods is often exaggerated. It's does matter, but to a smaller degree than is often portrayed. Also, the total glycemic effect of foods is influenced by the quantity of that food that you eat at a sitting. Smaller meals have a lower overall glycemic effect.

the same time, thereby reducing the average glycemic
index of the meal, if higher glycemic foods are eaten.
Also, glycemic index values can be misleading because they are based on a standard 50 grams of carbohydrate consumed.
It wouldn't take much candy bar to get that, but it would take four cups of carrots. Do you usually eat four cups of carrots at a meal?
Regular exercisers and active people also are less effected by higher glycemic foods because much of the carbohydrate comsumed is immediately used to replenish glycogen stores in the liver and muscle.

By the way, if you're interested in lowering insulin levels,
there is a great way to do that - exercise and activity.
7. Much of the weight loss on a low carb, high protein diet, especially in the first few weeks, is actually because of dehydration and muscle loss.
8. The percentage of people that re-gain the weight they've lost with most methods of weight loss is high, but it's even higher with low carb, high protein diets. This is primarily due to three factors:

There are literally reams of research over decades that clearly indicates that an increase in consumption of animal products and/or saturated fat leads to increased incidence of heart disease, strokes, gall stones, kidney stones, arthritic symptoms, certain cancers, etc. For example, in comparing countries with varying levels of meat consumption, there is a direct relationship between the volume of meat consumption in a country and the incidence of digestive cancers (stomach, intestines, rectal, etc.).

10. As someone recently told me, "it must work - people are losing weight". People that are truly losing fat on low carb, high protein diets, are doing so because they are eating fewer calories - that's the bottom line. There is no magic - the same can be done on a healthy diet.

too much fat as is often the case on a low carb high protein diet.
13. Amercans already consume more than twice the amount of protein needed. Add to that a high protein diet and you have far too much protein consumption. By the way, most people don't realize that all fruits, all vegetables, all whole grains, and all legumes also contain protein. Animal products contain larger quantities of protein, but that may not be a good thing.
