How long until the energy in Jake enters the bloodstream?

Say I want to do a sports activity that I will burn about 500 kcal on and I have an empty stomach.
How long before the sport should I eat Jake so that the energy in Jake is available at the start of excercising?
Will the energy from carbs be available before the energy from proteins and fats?
Will it become available gradually or will there be as spike?
Any guildelines, approximations, references or studies appreciated.

Hi @kwinz, Jake is made to give you a very smooth flow of energy. Indeed, simple carbs will be used for energy sooner than e.g. the fats. How long this takes and how gradual your energy uptake is, depends a lot on your personal metabolism and activity level.

Try and feel for yourself. Skip breakfast once and wait until your energy level drops, have a Jake, set a timer and clock when you'll regain energy. Notice if you have ups and downs. Measure your performance on a full stomach and compare it to how you feel when you've had Jake 2 hours before your workout.

What kind of sports/exercise do you do?

Hi Frank, thank you for your quick response.

The sports I do is running. Usually I run for 10km. The different sites that I read, suggest on average that for 10km/h running for 1h you should consume about 750kcal more.

At the same time I am losing weight. Which makes it very tricky. Say I want to consume 1500kcal/day baseline to lose weight and 750kcal on the 4 days per week where I run. So on running days I need 2250kcal.

Still I feel soo tired when I time the shake and or food wrong. If I do not eat enough the right time before running I just hit a wall after 20-40min of running and have to give up. That's why I want to time Jake exactly so that it "hits me" just before running. And still maintaining a caloric defficit for the overall day to lose weight. Thoughts appreciated!

Interesting topic. Would love to know more about the energy release of Jake and the way it influences the physical performance
