When energy intake exceeds energy expenditure (when the body is in positive energy balance), the body can store the excess energy as fat. However, the physiology of weight gain and loss is complex involving numerous hormones, body systems and environmental factors. Other factors besides energy balance that may contribute to gaining weight include:
Hypermetabolism is defined as an elevated resting energy expenditure (REE) > 110% of predicted REE. [1] Hypermetabolism is accompanied by a variety of internal and external symptoms, most notably extreme weight loss, and can also be a symptom in itself. This state of increased metabolic activity can signal underlying issues, especially ...
[149] [better source needed] Though it is accepted that energy consumption in excess of energy expenditure leads to increases in body weight on an individual basis, the cause of the shifts in these two factors on the societal scale is much debated. There are a number of theories as to the cause but most believe it is a combination of various ...

The Functional Food Centre at Oxford Brookes University conducted a study into the effects of chilli peppers and medium-chain triglycerides (MCT) on Diet Induced Thermogenesis (DIT). They concluded that "adding chilli and MCT to meals increases DIT by over 50% which over time may accumulate to help induce weight loss and prevent weight gain or ...
Exercise can cause short-term weight gain due to increased muscle, water retention, inflammation, medication, or thyroid issues. Doctors explain the causes. Why Am I Working Out But Still Gaining ...
The results indicated that the ketogenic diet was associated with lower blood sugar, improved memory and motor ability in older mice. Researchers showed there was improved plasticity in the ...
On average obese people have a greater energy expenditure than normal weight or thin people and actually have higher basal metabolic rates. [45] [46] This is because it takes more energy to maintain an increased body mass. [47] Obese people also underreport how much food they consume compared to those of normal weight. [48]
