“We have scientific evidence that it’s the quality of your diet that matters. Through diet, we can favorably support the detoxification process, oxidative stress levels and blood vessel health, and enhance weight loss. That’s an important public health message,”

Nutrition Journal study compared 2 days of intermittent nutritional fasting used in the HALO Protocol to 1 day of Intermittent nutritional fasting.
Comparison of 8 weeks of protein pacing with nutritional fasting used in the HALO protocol versus heart healthy Mediterranean-style diet on body composition and cardio-metabolic health outcomes (NO exercise). Groups were matched for total calorie intake and physical expenditure. The HALO protocol results in comparison to the Mediterranean Diet.
Comparison of 8 weeks of protein pacing with nutritional fasting used in the HALO Protocol versus the heart-healthy Mediterranean-style )diet on gut microbiome health outcomes. Both groups were matched for total calorie intake and physical expenditure.
The comparison of intermittent fasting with protein pacing (IF-P) protocols, specifically IF1-P and IF2-P, yielded several notable results in body composition and metabolic outcomes. Both groups experienced significant reductions in body weight, fat mass, and visceral adiposity, though the degree of fat reduction was more pronounced in the IF2-P group, which involved two fasting days per week.
The increase in fiber and reduction in sugar in both groups reflect improved food quality choices, within the calorie-matched diets. While both groups showed healthier eating patterns, the IF2-P group saw greater benefits, likely due to the extra fasting day.
The findings show that the strategies used in the HALO Protocol:
"The novel findings from this study may very well revolutionize how we prescribe weight-loss diets moving forward because of the increase in proportion of lean muscle and drastic reductions in abdominal and visceral fat mass during initial weight loss and the ability to maintain these favorable changes over the long term.”

“These were very impressive findings and clearly established our protein-pacing and intermittent fasting diet regimen as an effective short- and long-term strategy to promote healthy body weight, abdominal and visceral fat mass loss as well as enhanced metabolism and cardiovascular health compared to other commonly prescribed diets.”

“As an active nutrition and exercise science researcher for over 30 years, these were very impressive findings and clearly established our protein-pacing [Shake Days] and intermittent fasting diet regimen [Cleanse Days] as an effective short- and long-term strategy to promote healthy body weight, abdominal and visceral fat mass loss as well as enhanced metabolism and cardiovascular health compared to other commonly prescribed diets,"

During Phase 2 participants were separated into 2 groups:
Results: A Third of Visceral Fat Lost, Lean Mass Gained, Better Arterial Health, and Enhanced Metabolism.
Key findings after 12 weeks (phase 1) of following strategies used in the HALO Protocol (for all 3 data sets):
Key findings after 52 weeks (phase 2) comparing weight maintenance with The HALO Protocol vs. a heart-healthy diet (for all 3 data sets):
A 12-week protein-pacing calorie-restricted (P-CR) diet effectively reduced weight, improved redox balance, and increased blood PCB levels equally in obese men and women. A 52-week modified P-CR plan prevented weight regain without harmful effects like oxidative stress or abnormal blood results. This approach, with proper monitoring and guidance, is a safe and effective strategy for weight loss, improving redox status, and mobilizing PCBs.
The comparison between studies on the strategies used in the HALO Protocol, published in the Nutrition Journal, Obesity Journal, and Nature Communications, compared to the meta-analysis from the Journal of the American Medical Association (JAMA) and the New England Journal of Medicine, looking at around 48 randomized trials (studies) on well-known diets, highlights significant differences in outcomes regarding weight loss and improvements in various health markers.
Discover a 12 Month Study analyzing all diets by name. The results were very poor with an average weight loss on all diets of only 16 lbs. in a year. Note: The Journal of The American Medical Association Study was not conducted by Dr. Arciero. It was done by the American Journal of Medicine.
Results after 68 weeks were as follows:
This was a 12-month study broken into two groups. Group #1 reduced calories (as in most traditional diets) Group # 2 did Time-Restricted Eating where they did not eat for 16 hours and ate in an 8-hour window. This is known as the 16-8 diet.
Examines the impact of weight loss interventions on skeletal muscle mass (SMM) and strategies to mitigate muscle loss during weight reduction.
