Because 3,500 calories equals about 1 pound (0.45 kilogram) of fat, you need to burn 3,500 calories more than you take in to lose 1 pound.
While diet has a stronger effect on weight loss than physical activity does, physical activity, including exercise, has a stronger effect in preventing weight gain and maintaining weight loss. Moderate aerobic exercise includes such activities as brisk walking, swimming and mowing the lawn.

Clipping is a handy way to collect and organize the most important slides from a presentation. Potential energy is energy of position, based on the relative position of one object with another.
Modern work with the gravitational theory began with Galileo Galilei in the 1590s and continued with Sir Isaac newton in the 1680s. Gravity is an important force for large objects, but in the submicroscopic world of atoms it is negligible.
Much more important in chemistry is the potential energy known as electrostatic potential energy, Eel, arising from the interactions between charged particles.
Q is an electrical charge typically on the order of magnitude of the charge on the electron, 1.60 x 10-19 C.
When Q1 and Q2 have opposite signs, the two charges attract one another and Eel is negative. Since a joule is a small amount of energy, the unit kilojoules, kJ, is often used when describing chemical reactions. Traditionally, energy changes in chemical reactions have been expressed in calories, a non-SI unit.
A related energy unit used in nutrition is the nutritional Calorie (note the capital letter).
When chemists analyze energy changes, they focus their attention on a system, usually the reactants and products of a chemical reaction.
Heat is transferred between a system and its surroundings as a result of their difference in temperature.
The internal energy of a system is the sum of all the kinetic and potential energies of all its components. The equation above indicates the change in internal energy, ΔE, is the difference between the final energy, Efinal, and the initial energy, Einitial. A positive ΔE, when Efinal > Einitial, indicates the system gained energy from its surroundsings.


A negative ΔE, when Efinal Einitial, indicates the system lost energy to its surroundsings. In a chemical reaction the initial state of the system refers to the reactants and the final state refers to the products. Another way of saying this - as heat is added to or removed from a system, work is done on or by the system.
When a process (such as a chemical reaction) occurs in which the system absorbs heat, the process is called endothermic. The work involved in the expansion or compression of gases is called pressure-volume work, or P-V work. Enthalpy, H is the thermodynamic function that accounts for heat flow in processes occurring at constant pressure when no forms of work are performed other than P-V work. At constant pressure, a change in enthalpy equals the change in internal energy plus the product of the constant pressure times the change in volume. This equation indicates two moles of hydrogen gas burn to form two moles of water at a constant pressure, releasing 483.6 kJ of heat.
Enthalpy change during a chemical reaction can also be represented in an enthalpy diagram, showing the reactants at the top and the products at the bottom. The magnitude of ΔH is directly proportional to the amount of reactant consumed in the process. The enthalpy change for a reaction is equal in magnitude, but opposite in sign, to ΔH for the reverse reaction. All substances change temperature when they are heated, but the magnitude of the temperature change produced by a given quantity of heat varies from substance to substance.
The heat capacity, C of an object is the amount of heat required to raise its temperature by 1 K (1 oC). Hess's Law states that if a reaction is carried out in a series of steps, ΔH for the overall reaction will equal the sum of the enthalpy changes for the individual steps. Enthalpy changes associated with the formation of a compound from its constituent elements is known as enthalpy of formation, (or heat of formation), ΔHf. To compare enthalpies of different reactions, a set of conditions must be defined at which the enthalpies will be tabulated. The standard enthalpy change, ΔHo, of a reaction is defined as the enthalpy change when all reactants and products are in their standard states.
The standard enthalpy of formation of a compound, ΔHof, is the change in enthalpy for the reaction that forms one mole of the compound from its elements, with all substances in their standard states.
By definition, the standard enthalpy of formation of the most stable form of any element is zero, because there is no formation reaction needed when the element is already in its standard state.
The equation above states: the standard enthalpy change of a reaction is the sum of the standard enthalpies of formation of the products minus the sum of the standard enthalpies of formation of the reactants. The amount of energy our bodies require varies considerably depending on such factors as weight, age, and muscular activity.


About 100 kJ per kilogram of body weight per day is required to keep the body functioning at a minimal level. So if you cut 500 calories from your diet each day, you’d lose about 1 pound a week (500 calories x 7 days = 3,500 calories). Get at least 150 minutes a week of moderate aerobic activity or 75 minutes a week of vigorous aerobic activity. This chart shows the estimated number of calories burned while doing various exercises for one hour. Because of changes that occur in the body over time, however, calories may need to be decreased further to continue weight loss. However, to effectively lose or maintain weight, some people may need up to 300 minutes a week of moderate physical activity.
No specific amount of time for each strength training session is included in the guidelines. Strength training can include use of weight machines, or activities such as rock climbing or heavy gardening. Specific calorie expenditures vary widely depending on the exercise, intensity level and your individual situation.
The guidelines suggest that you spread out this exercise during the course of a week, and sessions of activity should be at least 10 minutes in duration.
Allure; Architectural Digest;You're Not Eating Enough Calories to Lose WeightHow Many Calories Should You Be Eating?
In order to successfully lose weight, you need to overestimate how many calories you are taking in by around 10%-15%. When you’re creating a calorie deficit on a daily basis, this can help you tremendously. Not to mention the fact that protein has a greater thermic effect (your body burns more calories processing protein than fat or carbs). If 2 people are eating the same amount of calories, the person with the highest amount of protein in their diet will have better results. How to Apply This Information Let’s do a case study so that I can show you how to apply all of this information. There is a very interesting and helpful video presentation that talks more in-depth about this method and and the author.
