Skipping one meal daily and restricting calories aids weight loss. Urine analysis of insulin and lactate levels can quantitatively track dietary changes and weight loss success in dieting individuals.
Area of Science:
- Metabolic Health
- Dietary Science
- Biotechnology
Background:
- Dieting success varies greatly due to personal factors.
- Existing digital tools lack personalized biofeedback.
- A novel platform integrates lifestyle tracking with molecular biofeedback.
Purpose of the Study:
- To investigate the efficacy of a meal-skipping diet for weight loss.
- To explore the correlation between urinary lactate and insulin levels with weight loss.
- To develop a quantitative approach for monitoring dietary behavior.
Main Methods:
- Participants skipped one main meal daily, restricting caloric intake to approximately 1200KCal.
- A mobile health platform was utilized for tracking food intake, weight, and urine samples.
- A survey assessed participant motivation, sample collection willingness, and reasons for dropout.
Main Results:
- Meal skipping significantly promoted weight loss over 24 hours compared to a three-meal routine (p < 0.001).
- Urinary insulin and lactate levels differed significantly between healthy and obese individuals (p = 0.01 and 0.05, respectively).
- Participant motivation was primarily driven by weight loss goals and interest in their metabolic profile.
Conclusions:
- Meal skipping is an effective strategy for weight loss.
- Urinary insulin and lactate show potential as biomarkers for monitoring dietary intake and weight loss.
- The integrated platform offers a quantitative method for biofeedback in dieting individuals.

Molecular Weight of Step-Growth Polymers
As the step-growth polymerization involves step-wise condensation of monomers, the molecular weight also builds up eventually. Consequently, high molecular weight polymers are obtained at the late stages of the polymerization, where 99% of monomers have been consumed.
