Estimation of Calorie Deficit (CD) by Assessing the Energy Parameters and Physical Activity Level (PAL) in Overweight Indian Women

Calorie (Kcal) reduction or deficit calculations for those who are overweight or obese lack a clear set of rules, an equation, or a theory in the literature. Although recommendations to cut caloric intake by up to 500 kcal per day have been made in Western countries. Additional research is needed to support energy consumption and expenditure. The difference between estimated Total Energy Expenditure (TEE) and Daily Energy Expenditure (DEE) is what this research article calls the “cutting value” of daily energy for an overweight or obese woman. The study found that using multiple regression analysis, r as correlation coefficient = 0.839 (‘good fit’ as close to 1), R² = 0.704 (reliable). The p-value is less than .001, indicating that the model is highly statistically significant (p < 0.05). The study concludes that an effective formula for finding Calorie Deficit (CD) with low error can help researchers with further research. More importantly, dietitians can also recommend near-to-correct kilocalories reduction to an overweight or metabolic syndrome patient using this simple formula.
