The problem is, its hard to determine what you truely are eating, in calories, and what you are truely burning. Because your metabolic rate changes. I know some websites that said i needed to eat 3600 calories because that was my resting metabolic rate. That is insanity. I calculated my daily needs by activity, and it was about 2600 resting. That 1000 is huge. I am not sure that 1000 is true or not, some activities seemd idiotically high in calories per minute.
Also with carbs, its ok to eat veggies as much as you want, excluding root vegetables like potatoes. But greens, peppers, shrooms, ect... have at it. Just stay away from Legumes , sugars and grains. notice, corn is a grain..
The key issue is regulating your insulin levels, legumes, sugars and grains causes a spike in your insulin levels. This is because your body want to fight againts the spike in carbohydrates in your body. This has a bad effect on your body because it inhibits proper hormone production in your body. It causes you to become more hungry, faster. It also causes you to become insulin resistant, which can lead to diabetes. Also, these type of foods have high inflammatory characteristics, which leads to heart disease.
Things you want to eat;
Meats (pork, beef, poultry, fish), Veggies, Fruits (sparenly), nuts, dairy (high fat as possible, whole milk as the worst, drink sparenly), healthy fats (no trans fats, or partially hydrogenated)
Grains, Beans/legumes, sugars, unhealthy fats
Saturated fats and cholesterol intakes has nothing to do with hearth disease. Heart disease has become a leading killer of people in the united states, even with many people going on low fat diets. The reason is they keep eating an insane amount of grains and sugars. These spike your system, which is not good. Insulin production is your bodies reaction to carbs, its to protect your body from them. Your body doesn't have an immediate response to fats or proteins. This leads to that our bodies are made to eat proteins and fats, rather than grains.
Also note, humans have been around for 2.5 million years. Grains have only been cultivated for 11000 years (rice in china). That means for 99.56% of the amount of time humans have been on earth, we have eaten proteins and fats as our primary source, with additions of eating veggies, fruits and nuts. only 0.44% of the time have we eated cultivated grains. Our bodies are not made to eat grains, processed foods, beans/legumes, sugars, or man made processed fats (trans fats)
