Diet and Fitness Craze
January 5, 2017
As always during the beginning of a year, the wild and crazy diet advertisements appear. This is not new, there have been many unrealistic offers over decades and it is probably not going to go away soon. The ones that always gets me are those promising huge amount of weight loss in very little time. Let’s talk about the one I just saw this morning: 17 lbs. weight loss in 30 days. Let me show you why this is unrealistic and marketing BS!
For most people, the general healthy guideline of daily calories intake is about
1500-1600 calories per day for women
2000-2100 calories per day for men
Of course, those numbers will vary based on lifestyle, level of activity, exercise and whether one is trying to lose weight or gain weight.
To lose 1 lb. of fat, one needs to burn 3500 calories. To do so, one can reduce food intake and/or increase calorie burning through exercise. The healthier way is the combination of the two. But let’s just assume a minute that we are looking at reducing only food intake. To safely lose weight, one must reduce calorie intake by about 300 to maximum 500 calories per day. (500 x 7 days = 3500 calories per week). Going beyond the 500 calories a day can result in serious health issues from dehydration to nutrients deficiencies and loss of muscle mass rather than fat.
The maximum rate that the body can lose fat is around 1% of body mass a week. So, if a female weighs 130 lbs., she can expect to lose 1.3 lb. per week, if she reduces her caloric intake by 500 calories a day or 3500 calories per week.
If we consider the 17 lbs. in 30 days, the numbers work like this:
17 lbs. x 3500 calories = 59,500 calories in 30 days
59,500 :30 days = 1,983 calories a day
1,983 x 7 days = 13,881 calories per week.
As you can see, 17 lbs. in 30 days is totally unrealistic. You could not exercise enough either to make up for those calories without passing out. Seriously, such extreme weight loss is not just ridiculous, it is insane and dangerous. Hopefully, it is nothing more than a marketing gimmick!
