As you can probably imagine, there is no consensus on what is the best exercise to lose weight. Using what we know about exercise and the human body, however, it is easy to see what workout routines would be the most beneficial. In order to burn fat your body needs oxygen, which means that an aerobic workout is needed to lost weight quickly. And while running sprints or swimming may seem good for shedding pounds, they are actually anaerobic activities.
Another important component of weight loss is having muscle mass. While this may seem counterintuitive, muscle actually burns a high number of calories; so the more muscle you have, the higher number of calories you will burn throughout the day. Taking these two thoughts into consideration, I feel that circuit training is the most effective exercise routine to burn weight in a hurry. Because you are doing low reps and quickly moving from machine to machine, you are able to stay in an aerobic state. And following a weight lifting workout, you maintain a heightened metabolic rate for hours after you are done—not to mention you are building highly efficient muscle.

Contrary to what you may think, there is no secret formula to losing weight and you are not eternally cursed by their genetics. In actuality, losing weight comes down to a simple math equation: eat less calories than you burn. Of course, the key to knowing how many calories I should eat to lose weight hinges on the amount of calories that you burn. The FDA suggests a 2,000 calorie diet, but there are a myriad of factors that can skew this number, including: age, gender, muscle mass, metabolism, etc.
The easiest way to figure out how many calories should I eat lose weight is by keeping a food diary of everything that you consume for a week and computing a daily average. If you have been gaining weight, you are not burning that number of calories; if you are losing weight, you are burning more. In order to lose weight the answer to simple: you either need to decrease the amount of calories you intake or increase the number of calories that you burn.
