Farrah Abraham blasted Amber Portwood for leaving "Teen Mom OG." But, Abraham herself has been under fire for supposedly giving her 7-year-old weight loss tea to purge Halloween candy. Abraham didn't, and it was only milk in the child's cup. But according to new medical wisdom, "teatoxes" aren't any better for parents than they are children. If you want to lose holiday pounds, says the British Dietetic Association (BDA), practice portion control, exercise, common sense, and moderation. Ahead of Christmas, the BDA debunked detox teas and four other popular celebrity fad diets.

Farrah Abraham teatox bad for 'Teen Mom' and child

The problem with weight loss tea like Abraham's is not that they aren't natural. It isn't even that these teas contain caffeine, yerba mate, or guarana--those can help reduce swelling and inflammation and control pain. You have to watch the quantity of caffeine and factor it into your daily intake. You should also mind the source and look for those with matcha green tea. The diuretic and laxative properties are the issue. Some contain hidden chemical laxatives, but even natural dandelion, nettle and senna aren't safe to use more than a week without medical supervision. Dr. Now of "My 600-lb Life" doesn't even recommend these for his morbidly obese patients.

Obesity is best tackled with better eating habits.

Messy logic behind "clean eating"

Other celebrities have bragged weight loss by eating "clean" (whole grain, organic, pure) foods. The BDA says that while it's healthy to avoid preservatives and processed foods as much as possible, it's not the be-all-end-all.

Most all foods are processed to some extent. The BDA cautions against labeling some foods "clean" as if others are dirty. Further, little evidence supports weight loss from "clean foods," and more show that calorie counting sheds the pounds.

Skip the diet pills, green juices, fasting

Kim Kardashian, Blac Chyna, Mariah Carey and others have talked using these types of fad diets.

Diet pills have the same dangerous ingredients as teatoxes, and more. Green juices haven't been shown to actually detox the body, and many contain loads of sugary, fatty, and highly-caloric ingredients (fruit juice, avocado, squash). A better diet drink to beat the post-holiday pudge is the power smoothie with protein in Greek yogurt and seeds to balance the juice. These boost metabolism, curb hunger, and provide a natural appetite suppressant. Fasting is a problem because it causes lethargy, poor concentration, blood sugar spikes, and mood swings. And no one needs those in the chaos of Christmas!
