Yes
No, apples do not have negative calories. They contain calories that provide energy when consumed.
No. It is impossible for a food to contain negative calories, or anything for that matter, however it does require more energy to digest celery than the celery provides, which led to it being called a negative calorie food.Most people that dispute this say it would only take 1 calorie per hour to chew it up, ignoring the rest of the digestive process which is where most energy is consumed.
There are 75 calories in 1 medium size head of iceberg lettuce (about 6" diameter).
Lettuce is very low in calories, with most varieties containing about 5 to 15 calories per cup when raw and chopped. For example, a cup of romaine lettuce has approximately 15 calories, while a cup of iceberg lettuce has around 10 calories. Because it is primarily composed of water, lettuce is often included in salads and dishes for its crunch and volume without adding significant calories.
By water lettuce, I assume you mean iceburg lettuce. I figure it would take about 4 heads of lettuce to make one pound (a medium sized head is about 250g). There are 90 calories in each head, so:90x4 = 360 caloriesThat's without any dressings, oils, spices, etc. - just the lettuce.Lettuce has been called a negative calorie food. It takes more energy to chew and digest the lettuce than it provides in calories.
The calorie count for a whole wheat bread sandwich with jam, lettuce, and regular mayo can vary based on the specific ingredients used. On average, two slices of whole wheat bread contain about 160 calories, a tablespoon of jam has around 50 calories, a couple of lettuce leaves add minimal calories, and a tablespoon of regular mayo contributes approximately 90 calories. In total, such a sandwich would roughly contain about 300 calories, but this can vary based on portion sizes and specific brands.
15-40 calories, depending on the type of greens. Darker greens contain more calories than iceberg lettuce, for example.
1 full head of lettuce is between 40 and 60 calories.
diet sodas if that counts... but also, celery has negative calories actually! it has so little calories that the calories it does have, you burn while chewing it.
The bread (it varies based on type, size, brand, ect.) is probably, assuming you have 2 slices, between 150 and 200 calories, and the lettuce is 30 calories. So the sandwich in general is probably about 180 to 230 calories or so.
That depends on how much you are holding in each hand and whether the lettuce is whole leaf or shredded. For example, there are 2 calories in large leaf of iceberg lettuce. .
Celery does not contain negative calories. While it is very low in calories, the energy required to eat and digest celery is minimal compared to the calories it provides.
