what is the strenght of low fat diet?
what is the strengths,weakness, safety issue and the advice to people on this diet. What are the strengths, weakness, safety issue of low carbohydrate diet and the advice to people on this diet. The straights, weakness, safety issue of liquid diet and the advice to people on this diet.
Fat won’t make you fat (but a low fat, high carb diet can). Fat is essential to good health. (not including transfats) & supports a strong immune system & helps hormones to function properly. Fat tempers the devastating health effects of carbohydrates. Fat is needed to make the vitamins & minerals in your foods bioavailable so they can be incorporated into the body structure. Most people do better with a higher level of fat than with less.
The body can not release body fat stores until the bloodstream is clear of insulin. Carbs greater than 9grams per hour trigger insulin. Insulin is the only fat storage hormone. As healthy as fruit may be, fructose the sugar in most fruit is the most lipogenic (fat producing) carb.
There is no better way to bring the body to the state of optimal health than with a low carb way of eating. Low carb doesn’t cause high blood pressure, high blood sugar or high cholesterol, it cures it. Anything less that 9 grams of carbs per hour controls insulin and is considered low carb (up to 144 grams per day).
U.S. government guidelines were changed 35 years ago to suggest we lower our fat intake & increase our carb intake. American society followed these recommendations & lowered their fat intake by 11%. In this same time frame obesity, diabetes, heart disease are all at epidemic levels.
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* to be fueled by ketones, it does require glucose also, but glucose can be converted from protein.
Plaque build up in the arteries is more attributable to carb consumption than Dietary fats, which seems to be 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 & heart disease.
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.
Gary Taubes who wrote "Good Calories, Bad Calories" spent 7 years going through all the studies over the last century & dividing up the real science from the faulty science & concluded that low carb was the best way to control insulin levels which balances out other hormones & allows the body to function properly.
His main points are:
1. Dietary fat, whether saturated or not, is not a cause of obesity, heart disease or any other chronic disease.
2. The problem is refined carbs in diet, their effect on insulin secretion & the hormonal regulation of homeostasis.
3. Sugars are particularly harmful, fructose & glucose simultaneously elevates insulin levels & overload liver with carbs.
4. Through their direct effects on insulin & blood sugar, refined carbs, starches, sugars are the dietary cause of coronary heart disease & diabetes. They are likely dietary causes of cancer, Alzheimer’s & other diseases.
5. Obesity is a disorder of excess fat accumulation, not overeating.
6. Consuming excess calories does not cause us to grow fatter.
7. Fattening is caused by an imbalance in the hormonal regulation.
8. Insulin is the primary regulator of fat storage. When insulin levels fall, we release fat from fat tissue.
9. By stimulating insulin secretion, carbs make us fat.
10. By driving fat accumulation, carbs also increase hunger & decrease the amount of energy we expend.

I’ve used every diet in the book but nothing worked as well as acai berry. I realize they say that pills will not work, however they sure worked for me, and they’ve been featured on CBS News too. There is a free trial happening currently at http://ryhebs.myweightlossforyou.info , give it a try, what have you got to lose?

The obvious way to burn fat is to eat less and move more often, the issues surface when we actually aim to put that into practice! There are loads of stumbling blocks in the real world don’t you think?! I learned some splendid information by learning from the site in the box below, they have loads of tips, I lost 7 pounds by following their tips.

The brain gets its energy from ketone bodies when insufficient glucose is available. In time the brain reduces its glucose requirements from 120g to 10g per day.
Ketones have been described as "magic" in their ability to increase metabolic efficiency, while decreasing production of free radicals, the damaging byproducts of normal metabolism. The heart and brain operate 25% more efficiently using ketones as a source of energy

FINALLY they admit - no difference in the risk of heart disease even with highest intake of saturated fat & eggs are a superfood & have no effect on cholesterol
