if you change your calorie intake from like 2700 or some shit like this to 1000 cals a day, wont you bodies metabolism just adapt fast so you actually wont loose as much fat as you think because of starvation adaption...
thats what chatgpt says about it:
The effect you are describing is often referred to as "metabolic adaptation" or "adaptive thermogenesis." When you drastically reduce your caloric intake, for example from about 3000 calories to 1000 calories per day, your body responds in several ways:
1. **Metabolic Slowdown**: The basal metabolic rate (BMR), which is the number of calories your body burns at rest, decreases. This is a natural protective mechanism of the body to conserve energy and ensure survival.
2. **Hormonal Changes**: Hormones such as leptin, ghrelin, insulin, and thyroid hormones change to lower energy expenditure and increase appetite. Leptin, the satiety hormone, decreases, leading to increased hunger, while ghrelin, the hunger hormone, increases.
3. **Loss of Muscle Mass**: With extreme calorie reduction, the body may start to break down muscle tissue for energy, especially if protein intake and strength training are insufficient. Muscle mass is metabolically active, and its loss leads to a further reduction in calorie expenditure.
4. **Reduced Thermogenesis**: The body's heat production through metabolic processes and physical activity decreases. This includes the thermic effect of food (the energy required to digest, absorb, and process nutrients) as well as the energy expended for daily activities.
These adaptations make it harder to continue losing weight and can also lead to rapid weight regain when caloric intake is increased again, a phenomenon often referred to as the "yo-yo effect."
A slower and more controlled approach to reducing calories, combined with regular physical activity, particularly strength training, and adequate protein intake, can help minimize these negative adaptations and maintain weight loss.
and also interesting is this experiment which says YOUR METABOLISM WILL DECREASE 40%
