What's up with Khloe Kardashian and weight loss? There's more to her dropping 40 pounds than just "Revenge Body." Khloe dished up her secrets, but doctors don't approve of any of them. Kardashian's path to thin included divorce, eating disorder tendencies, a weight loss supplement called garcinia cambogia and plastic surgery.

Khloe Kardashian's dubious exercise tips

When the reality television icon split from husband Lamar Odom in 2013, she needed an outlet for stress. So Khloe took it to the gym. She claims that inner clarity was the goal and weight loss just a happy by-product.

Out of that grew "Revenge Body" -- a hardcore workout approach to health. Khloe says she doesn't diet, but then contradicted herself. A few months ago she posted a picture fat-shaming herself, saying: "put the fork down, Khloe." She also uses garcinia cambogia to burn fat.

Doctors frown upon 'exercise-only' approach

Is the reality television star fit from working out, or from an eating disorder like anorexia? Obesity isn't a problem for Khloe but even if it was, medical wisdom would warn against both of her methods. Obviously, eating disorders, restricting nutrition, and crash diets are dangerous. But too much fitness focus can sabotage weight loss, say "The Doctors." Folks often go to the gym and then reward themselves by indulging.

The cast of "Keeping up with the Kardashians" is always eating and spends more time taking selfies than actually exercising.

Weight loss or plastic surgery?

You can't lose weight without changing eating habits, say health professionals on "The Doctors." This isn't the only way the reality TV star has been disingenuous. She's flaunted her tiny Barbie doll waist but some of that was plastic surgery, shape-wear, and creative photographing.

Kardashian's massive butt implants and boob job make the waist appear smaller in comparison. Does it matter? Yes, because it confuses people. Mama June Shannon of "Honey Boo Boo" thought she could have a tummy tuck any time, but "Botched" surgeons refused to do one until she lost more weight.

Docs naysay Kardashians' weight loss supplements

Khloe used garcinia cambogia, a fat burner with HCA hydroxycitric acid, to slim down. If it's all about fitness, why use garcinia cambogia as an appetite suppressant too? Integrity dictates being upfront about how you manage weight loss. Dr. Oz touted this herbal diet aid to aid in combating obesity, and many have found it helpful (including sister Kim Kardashian). However, clinical research argues against efficacy. Also, overuse can cause headaches, stomach trouble, and liver toxicity.
