This double-blind clinical trial study was conducted on 42 obese and overweight individuals (25 < BMI < 35). Participants were selected from those, who referred to a nutrition clinic (Ahvaz, Iran). Participants were screened based on the inclusion and exclusion criteria. Inclusion criteria were lack of physical activity, no smoking, no alcohol drinking, no usage of herbal supplements and vitamins, and lack of weight changes in the last 6 months. Exclusion criteria included pregnancy, breastfeeding, use of drugs that effect metabolism, lipid and glycemic profile, eating disorder, diabetes, cardiovascular disease, kidney problems, thyroid, digestive, respiratory diseases, and cancer. Participants consuming more than 300 mg of caffeine daily (described as caffeine users) were excluded from the study (20). The level of physical activity was assessed weekly by phone. The subjects, who had moderate or various physical activities, were excluded from the study.
This popular plan recently underwent a rebranding to create a more balanced program, changing its four-phase approach with the help of a science advisory board. The Atkins Diet is still low-carb, but you won't be chowing down on steak and eggs all the time to promote weight loss. Lean protein is still key, but there's more of a spotlight on fiber, fruit, vegetables, and healthy fats.
Because men are larger than women on average and have more muscle to support, men can usually eat more calories while still losing weight, compared to women. Portion control may be especially important for women. In one study, women who ate smaller portions of food (and less food overall) had lower BMIs than women who limited or avoided a certain type of food.2 This approach seems to work better for women than men.3
