Is there such a thing as Starvation effect that prevents weight loss when dieting?
Yes, there is such a thing as ‘starvation effect’. It happens when you don’t eat enough and I’d say 1200-1400 cals/day is not enough for the exercise you do. You may only burn 800 per session on the machine but your metabolism stays boosted even after your session. You might want to try bumping up to 2000 cals/day OR cutting your exercise time to 30 min if you want to keep your cal intake the same. Even so, you can still sometimes plateau and the only thing to do for that is grin and bear it. It may take a year to get into the shape you want but it’s worth it. I’d say you’ve done well so far at 2 lbs/week. That’s what a Dr. would advise.
Homeostasis The relatively constant conditions within organisms, or the physiological processes by which such conditions are maintained in the face of external variation. Similar homeostatic controls are used to keep factors such as temperature and blood pressure weight nearly constant despite changes in an organism’s activity level or surroundings. Such systems operate by detecting changes in the variable that the system is designed to hold constant and initiating some action that offsets any change. All incorporate a sensor within the system that responds when the actual condition differs from the desired one, a device to ensure that any action taken will reduce the difference between actual and desired, and an effecter to take the needed action as directed. The crucial aspect is that information is fed back from effecter to sensor and action is taken to reduce any imbalance—hence the term negative feedback. It soon becomes clear that the body’s function involves countless homeostati
