During the 1930s people carried out more physical activities as there was less means of transport and most of the jobs they had also asked for a lot of movement. Because of this they had to eat more food and have a higher intake of energy. In the 1980s cars had been developed and less physical activities were being carried out so naturally the amount of energy needed decraesed as they were burning less.
Body weight decrease if energy intake and expecture is the same due to the internal body metabolism .
Weight is determined by the balance between energy intake and energy expenditure. When energy intake exceeds expenditure, the excess energy is stored as fat, leading to weight gain. On the other hand, if energy expenditure exceeds intake, the body uses stored energy reserves, resulting in weight loss. Maintaining a balance between energy intake and expenditure is crucial for weight management.
decrease in oral intake
Eat less.
I was told my a dietician that I need to decrease my carb intake and increase protein
This statement is incorrect. When energy balance in the body is positive (caloric intake exceeds caloric expenditure), body mass increases. To decrease body mass, energy balance must be negative (caloric intake is less than caloric expenditure).
decrease in oral intake
Drink less, eat while drinking, drink non alcoholic drinks between alcoholique ones.
their muscles begin to atrophy and require less energy
Think simple concept of energy balance. Energy in must equal energy out. In general, 3500kcal = 1lbs of fat loss. You can either achieve this through decreasing your intake of calories from food or increasing your energy expenditure through exercise. However, if you strictly decrease your food caloric intake----it may decrease your overall metabolism. The body may go into a starvation mode and store much of the calories as fat. The best way loose weight is to exercise and to eat a healthy balanced diet.
Yes, water intake decreases fat deposits because it removes toxins in the cells. This will decrease your water weight and fat deposits.
Energy balance can be described by this equation : Energy intake = internal heat produced + external work + energy stored.
