Effects of Almond Versus Pistachio on Weight Loss

March 28, 2018 updated by: Novindiet Clinic

Effects of Almond Versus Pistachio on Weight Loss of Obese and Overweight Female Adults During Hypoenergetic Diet - a Randomized, 12 Week Clinical Trial

The purpose of the current study is comparing the effect of almond and pistachio, as the two common types of nuts, consumption on healthy obese and overweight female who following a hypocaloric diet for 12 weeks. The secondary aim of the current study is to evaluate of these two type of nuts on other cardiometabolic risk factors.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Weight
Time Frame: 12 Weeks
Body weight was taken to the nearest 0.1 kg using a digital calibrated scale (Omron Health Care, Hoofddorp, Netherland), whilst subjects wore light clothing and no shoes.
12 Weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Waist circumference
Time Frame: 12 Weeks
Waist circumference (WC) was measured with a rigid measuring tape and recorded to the nearest 0.5 cm. WC was measured at the smallest horizontal circumference between the ribs and iliac crest (the natural waist), or, in case of an indeterminable waist narrowing, halfway between the lower rib and the iliac crest.
12 Weeks
fasting blood glucose
Time Frame: 12 Weeks
Fasting plasma glucose (FPG) were measured using the enzymatic colorimetric method.
12 Weeks
HbA1c
Time Frame: 12 Weeks
Glycated hamoglobin (HbA1c) was measured by a colorimetric method after an initial separation by ion exchange chromatography (Biosystem, Barcelona, Spain).
12 Weeks
HOMA-IR
Time Frame: 12 Weeks
Insulin resistance was evaluated by homeostasis model assessment of insulin resistance (HOMA-IR), which was calculated by using the following formula HOMA-IR = [fasting insulin (mU/l) × FPG (mmol/l)]/22.5
12 Weeks
lipid profiles
Time Frame: 12 Weeks

Biochemical analysis of the serum total cholesterol (TC), triglyceride (TG), and high-density lipoprotein (HDL) cholesterol was carried out on a Selectra E auto analyzer (Vita Laboratory, Netherlands) following standard procedures of the Pars Azmoon diagnostic kits (Iran). The LDL cholesterol was calculated using the Friedewald formula.

LDL cholesterol = TC - HDL cholesterol + (TG ÷ 2.2)
12 Weeks
liver function tests
Time Frame: 12 Weeks
AST ALT
12 Weeks
Insulin
Time Frame: 12 Weeks
Insulin was measured by using a radioimmunoassay with 125I-labeled human insulin and a human insulin antiserum in an immunoradiometric assay (IRMA) (Biosource, Dorest, Belgium) with a gamma-counter system (Gamma I; Genesys).
