You need to understand how weight loss occurs so as to be able to know how long it takes to lose weight. You do not just wake up every morning to find out that you have lost some weight; you have to put in some hard-work to making this come true. Weight loss can only be achieved if you consume fewer calories than you burn everyday and participate in regular exercises. Now, the answer to how long does it take to lose weight? Is dependent on factors like; your age, gender, calorie deficit, your initial body mass, how long you sleep.

  • AGE: Age can be a very important factor in determining how long it will take to lose weight. As one ages, there is an alteration in your body composition such that your fat mass increases and your muscle mass decreases. Some major organs in your body begins to require a fewer calorie intake, which results in a lower RMR. A low RMR can make weight loss very difficult. Studies have proven that adults who are over 70 usually have RMRs that are 20-25 percent which is lower than those who are younger.
  • GENDER:  women naturally have a greater fat-muscle ratio more than men. Women who are of the same height as men have a lower RMR of about 5-10 percent. This simply means when at rest, women burn 5-10 percent fewer calories than men do. This implies that men lose weight faster than women when on the same diet. However, when it comes to weight maintenance, gender doesn’t affect it.
  • CALORIE DEFICIT: in order to lose weight, you need to create a deficit in your calorie intake. How this determines how fast you lose weight is the extent of the calorie deficit. You need to have a high calorie deficit in order to lose weight quickly. Make sure the calorie deficit is not too high.
  • INITIAL BODY MASS: your initial weight before the weight loss program is another factor that determines how long you lose weight. Bear in mind that different weight losses in pounds can be equal to the same percentage of weight loss in different individuals. The heavier you weigh the faster and quick it is for you to lose weight.
  • SLEEP: most people usually do not think of this as an important factor, but it is.  Lack of adequate sleep can slow down the progress of your weight loss, it can reduce the speed. And so this means that when you are on a weight loss program and you sleep adequately, you tend to lose weight quickly than those who do not. Depriving yourself of one night’s sleep will make you crave for food high in calorie, which will hinder your weight loss plan.
  • MEDICAL CONDITIONS: Some medical conditions like diseases or the likes of depression and hypothyroidism can determine how long a person will lose weight, because such illnesses allows for a reduced production of metabolism regulating hormones by the thyroid gland leading to slow weight loss.


The Belly is one place that is a little difficult to lose the fat around it. You can lose belly fat if you put in a lot of efforts. According to a personal trainer and registered dietitian, Jim White says belly fat can be lost in two weeks. He added that the rate at which fat in the belly is lost depends greatly on the person alongside a calorie reduction and an increased participation in exercises. Jim White also said one can lose belly fat with two weeks of a proper diet and exercise program. Those who have more abdominal fat will get quick results. Note that the length of time to lose belly fat varies from person to person. Another thing to note is that there is a change in your body’s rate of fat loss when the body loses weight; this is because the body during weight loss usually recalculates the amount of fat to store for later use based on the present circumstances. This means fat loss rate tend to increase or decrease as you lose weight. When working out to lose belly fat, Jim White suggests that you engage in aerobic exercises as well as strength training. Tabata is a very good exercise for burning belly fat.
