Studies have shown that those who consume lower protein diets tend to live longer. Casein (milk protein) has also been shown to be incredibly harmful. Proteins are essential in the diet though, just not in too high a quantity.

Fats are essential also and the only fats that should be excluded from the diet are saturated fatty acids and trans fatty acids.

Carbs are a main source of energy and are easily broken down and absorbed. I’m sure you’ve heard about simple carbs and complex carbs. Simple carbs are quickly absorbed and spike your blood sugar level. They also leave you feeling hungry quicker. Complex carbs take longer to digest and are generally better to eat unless you need some energy quick like during or after a workout.

Protein is broken down into amino acids and used to build muscle. This is where you get your essential amino acids. When you don’t have enough fats or carbs in your diet for energy, then your body starts breaking down the proteins for use as energy. This takes a lot of energy to do, which is why high protein diets are popular. A lot of energy is consumed in the digestion process.

Fats are easily used as energy and you don’t want to completely eliminate them but you do want to limit them to as little as possible. You should also try to use better fats in your cooking, which is why so many people use Olive Oil when trying to cook healthier.

One of the arguments against the High-Protein diets you commonly hear about is they are also super low carb diets. It could cause problems with your kidneys. Eating all the meat can cause your diet to be high in fat as well, which is also unhealthy. A nasty side effect of digesting protein is the production of Ketones. If you mainly eat protein and no carbs, you’ll start to smell from the build-up as well.

The best loosing weight/cutting diet is to try to get around 30 to 40% of your calories from Protein. Try to get 50% from your carbs. You’ll also want to consume the carbs early in the day. I try to have the last meal of the day be no carbs or minimal carbs. You’ll also want to eat something every 3 to 4 hours to keep your metabolism up. This can be something as simply as a 150 calorie protein bar or some vegetables.

There are many side effects of this food additive with some people more sensitive than others. In general, I felt fuzzy and forgetful when I was drinking this soda pop over an extended number of years. After stopping the soda pop and changing my food choices to a "whole plant based diet," I lost the weight I had gained.

Read Dr. Neal Barnard for details about aspartame and a healthy diet. Dr. Dean Ornish wrote "Eat More, Weigh Less." You can lose weight without feeling deprived or hungry.
