Question

Calculated DRI: 3570

Your Basal Metabolic Rate is: 2136 calories.

Your Average Daily Calorie Need Is: 2563 calories

Explain why in order to lose weight you would need to ingest fewer Calories per day, or expend enough energy per day, so the net ingested daily Calories are less than the calculated DRI. How long would it theoretically take to lose the equivalent of one pound of fat if you ingested 100 calories/day less than the DRI?

Would you agree that it basically does not matter what kind of food you eat to lose weight as long as the number of net daily Calories is less than the DRI and why?

Why do you think the BMR and DRI can change with body mass and fitness levels? Go to your kitchen and chose a favorite food product with a Nutrition Label and note the Caloric content. How much of that food (by mass or volume) could you ingest in a single day to equal the DRI if that was the only food you ingested? Please report the Caloric value per mass (or serving) of your food item and the total amount you could ingest.

Answer 1

Calories is a measure of energy. So more the calories we intake more the energy we are providing to our body.

For our every day to day work, physical or mental exercise we need energy and that is provided as calories.

The carlories are obtained from food we intake. So food is basically the source of energy.

To maintain a constant body weight we need to balance the calories consumed by our body to the calories intake by body in the form of food.

In our body we store some energy in the form of fat.

So if the intake of calories is less than the daily requirement of body, then the body will start burning the fat (utilization of fat as source of energy ) and will lose body weight.

So, Yes it basically does not matter what kind of food you eat to lose weight as long as the number of net daily Calories is less than the DRI.

BMR is the total minimum calories needed for the involantary activities including circulation in body ,digestion , respiration. so it may vary from person to person.
