In this podcast, I chat with scientist and friend Dr. Bill Campbell about a new study on rapid fat loss that came out of his lab.
In case you’re not familiar with Dr. Campbell, he’s a professor of Exercise Science and the Director of the Performance & Physique Enhancement Laboratory at the University of South Florida, who’s also published more than 150 scientific papers.
In other words, Dr. Campbell is busy conducting studies that test questions many of us have with answers we all want to know.
His latest study on rapid fat loss is a prime example. While most of us want to strip away fat as quickly as possible, we also don’t want to lose our hard-earned muscle in the process. So the question is, how aggressive should we be during a cutting phase to maximize our fat loss benefits and minimize any negative consequences of being in a deficit.
And that’s exactly what Dr. Campbell’s latest study looked at and the results actually changed his mind about rapid fat loss. In this episode, Dr. Campbell describes the study, the results, practical tips you can implement to lose fat as quickly as possible, and what future studies on this topic might look like.
So, if you want to learn about the latest research on losing fat fast without shriveling into an atrophied raisin of your former self, don’t miss this episode! Press play and let me know what you think.

How many grams protein per kg did the group eat of protein in the 40% deficit in two weeks?
Bill's lab may be the most exciting thing in the fitness industry. Great guest
🙌
Looking forward to the next podcast with Dr. Campell.
Wow, outstanding
Great content
Please get Lyle on and Martin MacDonald to talk about rapid fat loss….please!!
👍
Only one protocol- Lyle McDonalds rapid fat loss “ booklet !
starting now as cat 3..that means 2 free meals a day..would eating to maintenance on those days be the way to go>? also,,he cites fat free cheese..i can only get low fat..which is 4-5 gm oz...same w cottage cheese..i have "low fat" which is 1% vs 0%..we are talking about 4-5 gm per serviing....1/2 c / 4 oz - 6 oz..will these small extras hurt? I'm trying to make this doable for an extended period before a break..thanks..how long have you done it? what were results etc? thanks@@Marx1963
Bill is awesome. Love his stuff on Ig
I almost always do PSMF to get the cut done quick and then resume maintenance or massing. And once I switch to maintenance I always get a good bump in water weight pounds and my lifts go up fast. Banked muscle tissue that just didn't have energy to be fully used? I've done PSMF for like 1-2 months before. Usually more like 4-5 weeks now though just to keep body fat in check.
I've done a couple weeks of 230-250kcal/meal 4 meal/day all egg whites + fiber/greens powder + omega 3-6-9/fish/krill pills + multivitamin tablet + green tea diet with a 4 total body weight lifting sessions per week protocol for rapid far loss and it works rather well for me (6'1" 34yo male about 18%BF), although I will say I get the low body temperature, lower blood pressure, etc., associated with such a VLCD/PSMF.
Why not? That's his business.
Late to this video, but have a question. When your finished and lost lbs, is the maintenance your beginning weight? Seems you would gain back the fat.
Wow. When this bulk is over I'm totally going to cut hard and fast and get back to lean bulking.
👊
is there a link to the study? I cant find it on google scholar
may be this (abstract), pubmed.ncbi.nlm.nih.gov/33467235/ full www.mdpi.com/2411-5142/5/1/19
Starts at 5:30
is one and half kilos of weight lost over 2 weeks regarded as fast weight loss ,just wondering....
Lyle McDonald is the original OG of this protocol. PSMF - high protein - under 20 grams carb and fat . SMH this study has been done - including diet breaks and refeeds .
Rapid....Its the only kind of fat loss I like.
sorry boys, but 1 hour watching this conversation and... what is this about ? Conclusions...?
The solid 5:35 minutes of intro and plugging your products is so off-putting………such a shame as Dr Campbell so full of info
so Walmart can sell food but he can’t sell his products/help to provide for his family? 🤔
