1, it depends on whether your milk is full-fat, semi-skim or full-skim, and whether it is sweetened;

2. What is the capacity of this bottle? Is it 500ml or 1L? Is the banana a big one or a small one? It is best to have a rough number of grams.

3. For example: 1 cup of whole milk (200.0 ml) contains calories 108 kcal, which needs to be consumed by walking for 74.5 minutes;

1 banana (edible part 89.0g) contains 8 1 calorie, and it takes 55.9 minutes to walk.

The above added heat is about 150 calories.

4. In addition, it depends on the sugar content of bananas. Bananas are high-sugar fruits and can only be absorbed by liver glycogen. However, the fructose absorbed by human liver glycogen cannot exceed 5g every day, and the excess will be stored and converted into fat. So if you eat too much fruit, you will get fat.

The above is for reference only, and I hope to adopt it.
