The value obtained from this equation is the estimated number of calories a person can consume in a day to maintain their body-weight assuming they remain at rest. This value is multiplied by an activity factor (generally 1.2-1.95) dependent on a person's typical levels of exercise in order to obtain a more realistic value for maintaining body-weight (since people are less likely to be at rest throughout the course of an entire day). 1 pound of body weight, or approximately 0.45 kg, equates to about 3,500 calories. As such, in order to lose 1 pound per week, it is recommended that 500 calories be shaved off the estimate of calories necessary for weight maintenance per day. For example, if a person has an estimated allotment of 2,500 calories per day to maintain body-weight, consuming 2,000 calories per day for one week would theoretically result in 3,500 calories (or 1 pound) lost during the period.
Fat contains 9 calories per gram, which is more than twice the calories of protein and carbohydrates (4 calories per gram each). Limiting one’s fat intake will not only lower overall dietary fat and calories, but also reduce a critical risk factor for cardiovascular disease. A healthy goal for fat intake includes obtaining 20-35% or less of total calories from dietary fat (specifically receiving less than 10% of calories from saturated fat, and eliminate trans-fat completely).

Know your why: “When you set a goal, write down why that goal is important to you. Because when you mess up — and you will — you can go back and read what you wrote and why it was meaningful and that will make you remember why you started," says Delaney. "When you fail — because everyone will fail at some point — go back to the book and remember why you set the goal in the first place.”
Beware of Sugar: Your body processes carbohydrates differently than fats and proteins. Eating foods with a high glycemic index (those heavy in sugar and other quick-acting refined carbohydrates) will cause your blood sugar to quickly spike then crash, making you hungry again sooner. Whereas fats and proteins are processed slower and give you a sense of satiety which lasts longer. Calorie counting doesn't work for most people because it requires too much time, effort, and discipline. Eating vegetables and foods with a higher fat and protein content and less carbohydrates means you shouldn't need to count calories, as your body won't tell you that you are hungry when you don't need food. There are literally sugar candies in grocerie stores which are marketed using the label "a fat free food!" The "low fat" healty food marketing gimmicks came out of large agribusinesses creating demand for their frankenfood products.
We often think that if we can just discover the “right” combination of foods, we’ll magically lose weight or maintain what we’ve lost. There are low-fat diets, low-carb diets, low glycemic diets, Paleo diets, and a lot of iterations of all of these. Jensen points out that in fact there doesn’t seem to be any “right” diet, and there doesn’t seem to be any evidence that one particular diet will work better with an individual’s specific metabolism. “The big myth out there,” he says, “is that there’s a magical combination of foods – be it protein, vegetarian, and what have you – that’s going to be unique because of its unique interaction with your metabolism. We know pretty much that any diet will help you lose weight if you follow it. There’s no magic diet. The truth is that ALL Diets will work if you follow them.”
You can lower your LDL or “bad” cholesterol with healthier food and medications. But it’s harder to raise levels of the “good” kind of cholesterol, HDL. That’s the type that clears bad LDL from your blood, so the more you have, the better. Exercise and losing body fat can get you into the ideal HDL range: above 60 mg/dl, which lowers your odds of having heart disease.
