Is Marijuana the Secret to Weight Loss?

The stereotypical image of a person smoking marijuana includes the ever present “munchie” food – certainly those who have tried smoking pot report a craving for salty, sweet and junky foods. But often, users report that they find weight loss to be an unexpected and welcome side effect. Is there any truth to the rumor?

In 1985, the Department of Psychiatry and Behavioral Sciences, Division of Behavioral Biology at The Johns Hopkins University School of Medicine in Baltimore conducted a study. Nine male volunteers were asked to spend 25 days in a secluded laboratory. During the first part of the day, each subject participated in planned work, and after that work was completed, they were allowed to socialize with the other participants. Cigarettes containing either marijuana or a placebo were provided and smoking was allowed during both the work and social times.

Researchers found that a single marijuana cigarette smoked had no bearing on caloric intake, but additional cigarettes increased the calorie intake of the men. The marijuana smokers found that their calorie intake increased as much as 40%.  The additional calories did not come from increased meal portions, but from additional snacks, usually sweet foods like candy bars, that were ingested both during their private time as well as their social time.

The study seems to indicate that marijuana does not help people lose weight, but I know that I’ve heard anecdotal evidence that says otherwise. Anyone brave enough to share their experience?

I cant talk for myself as i think i had a fast metabolism even before i started smoking weed. but i saw with my own eyes 3 of my friends who were overweight when they started smoking weed, but slowly after smoking every day they lost that weight. it was a vey slow process that took around 5-10 months. and this was with the pigging out on munchies, eating what they wanted when they felt like it, so no dieting or extra exercize or anything like that. i also know/knew about 4 people who told me how they were overweight before thay started smoking weed and how weed magicaly made them loose weight(again no dieting or trying to loose weight) one of them was my gf for a while. and when she showed me pictures of her before she started smoking weed i could hardly believe it.

also now i come to think about it all my friends who smoked weed often have always been at a healthy bmi. i only have one stoner friend who is probably at the top of a healthy bmi index but he isnt exactly overweight either. and when you consider the obesity rate around here that is very unusual

one study i found done on mice which ight support this is
"A two-year study in which rats and mice were force-fed tetrahydrocannabinol dissolved in corn oil showed reduced body mass, enhanced survival rates, and decreased tumor incidences in several sites, mainly organs under hormonal control. It also caused testicular atrophy and uterine and ovarian hypoplasia, as well as hyperactivity and convulsions immediately after administration, of which the onset and frequency were dose related."

Pot also helps fight and possibly can cure brain cancer. THC found in pot kills cancer cells without killing healthy cells! save the earth help in the fight of legalizing hemp.

I agree 100%. By the time I graduated high school I was 18 years old and weighed 214 pounds. I started smoking pot as a recreational thing that January after I graduated and before I even realized what was happening I had already lost about ten pounds. I continued to smoke pot every day 2 to 3 times a day for the next 8 months and dropped a total of 84 pounds. That was over 12 years ago. I am now 32 years old and weigh 130 pounds and stand 5"6. I completely transformed by body.

Pot definitely helped me, see my trick was just not giving into the cravings, I ate healthy, but I did not work out once during the 8 months it took me to lose that weight. Now, since I dropped the weight, I do work out 5-6 times a week and have been for the past 10 years to maintain my weight, but do not smoke pot anymore. I actually stopped after all my weight was lost.

Good luck!

Clinical marijuana has been used to treat eating disorders like anorexia, because it increases hunger and can lessen anxiety.
