No, this is losing an average of 4.2 pounds a week. It is safe to lose 1 to 2 pounds a week. However, the more overweight you are the easier it is to lose weight. I myself lost between 3 and 4 pounds in a week at my heaviest just by cutting 750 calories a day and adding in some light exercise. It is best to consult a doctor if you plan to lose that much weight really quickly. The risk you take in losing it too quickly is saggy skin :(
Safe weight loss is 1 to 2 pounds a week, so that would be 12 to 24 pounds in 12 weeks.
It's impossible to lose 26 pounds in only 3 weeks and be safe about it. If you want to lose weight and keep it off, you need regular exercise and a reduced-calorie diet. There may be some fad diets out there that let you lose that much in only 3 weeks, but once you go back to eating normally, you'll gain all the weight back (or even more!).
To lose 15 pounds in 2 weeks would be not only impossible but nowhere near safe. That kind of weight loss would require a daily caloric deficit of 3,750, which would be extremely dangerous.
There is no safe way to lose that much weight that fast. Half that would be really pushing it. Two pounds a week is a reasonable amount. And if you lose 10% of your weight, it will be very noticeable.
diet and excercise. its not safe to lose weight fast regardless of age.
How much weight are we talking about? It's not safe or practical to lose more than a few pounds a week - or a month for that matter.
There is no safe way to lose weight except proper exercise and a sligt reduction in calorie intake. You should only lose 1-2 pounds a week and have a proper diet with nutrients and fiber.
Healthily it's 1 or 2 pounds a week.
It is extremely dangerous to try to lose that much weight in such a short period of time. The safe amount to lose is two pounds per week.
It is probably not safe to try and lose that much weight in so short a time. You can't gain it that fast, don't expect to lose it that fast. Eat sensibly and exercise. Ten pounds the first two weeks of a life style change is possible, but difficult.
There's no way to lose that much weight that quickly. It took you a long time to get overweight and it's going to take a long time to get thin again. Just do safe exercises and eat less and you'll get there.
AnswerLiposuction is probably the most effective way to lose 20 pounds in two weeks--which, of course, is not safe for ANYONE, let alone a 13-year-old girl. At the age of 13, you shouldn't even be considering losing 20 pounds in such a quick amount of time--no one should. And even if you tried losing weight on one of those gimmicky "48-hour Hollywood Diet," you'd primarily be losing water weight anyway--NOT FAT.Effective weight lossshould be done the smart, SAFE way--through a balanced, nutritious diet and exercise. You may not be able to fit into that dress in two weeks...but safe weight loss over the long haul should be what you go after.
