We are forever being told that high calorie and sugary snack foods are bad for us. We should limit out intake and stick to a healthy diet. But 41-year-old human nutrition professor Mark Haub of Kansas State University has proven otherwise with a 2 month diet.His food intake consisted mainly of Twinkies, Doritos, Oreos, and sugary cereal with a portion every 3 hours. His usual 2,600 calorie daily intake was cut to 1,800 so as to not eat more calories than he burned.AdChoices广告While you may expect his weight to balloon, or his cholesterol to go sky high, the sugary diet seems to have been of significant benefit to the professor’s health. In 2 months he lost 27 pounds, his body fat went from 33.4% to 24.9%, his bad cholesterol was lowered 20% and his good cholesterol went up 20%. He also had a lower level (39% less) of triglycerides which is a form of fat.The problem is, Haub can’t explain or decide if this is a good or bad thing to continue doing. We are told junk food is bad, but in the short term it seems to of had a positive effect:These foods are consumed by lots of people. It may be an issue of portion size and moderation rather than total removal. I just think it’s unrealistic to expect people to totally drop these foods for vegetables and fruits. It may be healthy, but not realistic.I wish I could say the outcomes are unhealthy. I wish I could say it’s healthy. I’m not confident enough in doing that. That frustrates a lot of people. One side says it’s irresponsible. It is unhealthy, but the data doesn’t say that. It’s important to point out that Haub did manage to also consume a multivitamin, protein shake, and the occasional vegetable like some sticks of celery. But no main meals were eaten beyond the junk food.A different diet before turning to junk food was attempted by Haub which was heavy on vegetables, fruit, and wholegrain food. But he didn’t lose weight mainly because he was taking in too many calories.Read more at CNNMatthew’s OpinionThis is clearly down to the reduction in calories. He was eating 800 calories less every day so the type of food being eaten is not that significant. However, this is a short term study and I bet if this was carried on for years then problems would surface.Top of the list for issues would be diabetes due to the high sugar content of all the food. There may also come a point where Haub’s metabolism changed and the calories being eaten may have to reduce further, but this could leave him hungry due to the high calories in these foods meaning he had to have fewer. We all know sugary snacks don’t keep us full for long.I’m sure Haub’s concentration and energy levels would also be effected. There’s nothing in those foods giving out energy slowly, it’s all quick bursts from the sugar.If you want to go on a diet then this clearly works, but only short term. I’d go back to regular meals, lots of fruit and veg, and limited junk once you’d lost a few pounds. The experiment shows watching your calorie intake is key to dieting so a similar setup using fruit and veg would probably wield similar results. However, it may be a lot harder to do for those who love their snacks.
