Intermittent versus daily calorie restriction: which diet regimen is more effective for weight loss?

Dietary restriction is an effective strategy for weight loss in obese individuals. The most common form of dietary restriction implemented is daily calorie restriction (CR), which involves reducing energy by 15-60% of usual caloric intake every day.

Another form of dietary restriction employed is intermittent CR, which involves 24 hours of ad libitum food consumption alternated with 24 hours of complete or partial food restriction. <<has similarities to JUDDD & MUDDD <<

Although both diets are effective for weight loss, it remains unknown whether one of these interventions produces superior changes in body weight and body composition when compared to the other. Accordingly, this review examines the effects of daily CR versus intermittent CR on weight loss, fat mass loss and lean mass retention in overweight and obese adults.

Results reveal similar weight loss and fat mass loss with 3 to 12 weeks' intermittent CR (4-8%, 11-16%, respectively) and daily CR (5-8%, 10-20%, respectively). In contrast, less fat free mass was lost in response to intermittent CR versus daily CR. These findings suggest that these diets are equally as effective in decreasing body weight and fat mass, although intermittent CR may be more effective for the retention of lean mass. <<that fat-burning, muscle-sparing effect<<

Abstract

Insulin signaling dysregulation is related to neural atrophy in hippocampus and other areas affected by neurovascular and neurodegenerative disorders. It is not known if long-term calorie restriction (CR) can ameliorate this relationship through improved insulin signaling or if such an effect might influence task learning and performance.

To model this hypothesis, magnetic resonance imaging was conducted on 27 CR and 17 control rhesus monkeys aged 19-31 years from a longitudinal study. Voxel-based regression analyses were used to associate insulin sensitivity with brain volume and microstructure cross-sectionally. Monkey motor assessment panel (mMAP) performance was used as a measure of task performance.

CR improved glucoregulation parameters and related indices. Higher insulin sensitivity predicted more gray matter in parietal and frontal cortices across groups. An insulin sensitivity × dietary condition interaction indicated that CR animals had more gray matter in hippocampus and other areas per unit increase relative to controls, suggesting a beneficial effect. Finally, bilateral hippocampal volume adjusted by insulin sensitivity, but not volume itself, was significantly associated with mMAP learning and performance.

These results suggest that CR improves glucose regulation and may positively influence specific brain regions and at least motor task performance. Additional studies are warranted to validate these relationships.

It took me a long time to gather enough evidence to make me believe that low carb was the healthiest way to eat. It's not taking near as long to convince me of the health benefits of IF. I think JUDDD + Primal is the just about the healthiest thing I can be doing for me. I'm thoroughly convinced.

Thanks for the research, Sophie!

Great! That's a really recent study. More proof of good benefits.

Agreed!! Although I don't eat primally, I do eat mostly whole foods (with the occasional treat thrown in for good measure), and I feel amazing.

Thank you so much, Sophie!!! I am slowly building up my JUDDD "library".

Wow! Thanks for posting!

Very interesting stuff here. Thanks for sharing.
