Glucagon and Aging - Breakfast How Not To Start The Day Part III


A question from one of our readers:

Dr. Mericle,

With respect to burning "fat" energy in the mornings before eating, what if you are not a long distance runner? The average person is not, particularly someone who is overweight. A typical run for me in my current condition is 2-3 miles. Would I still be burning fat with a 25-30 min. jog?

JoLee

Answer: Yes, you would still be burning fat as long as youstay in a glucagon state.

This is a very good question since most people today don't runat all -much less even 2-3 miles a day. This touches on one ofthe most important aspects of the MericleDiet and exerciseas it relates to weight loss. Exercise for your immune system,but don't rely on exercise to lose weight and or keep weight off. Even running seven miles a day is not enough to burnany significant calories.

Back to the glucagon state of energy utilization

In the last newsletter I discussed the importance of enteringa glucagon state for some part of every day. For me,running helps as it is a real distraction, something I do every day and I have my own rule of never eating before I run.The reason for not eating is that it is a lot easier to run in a state of energy utilization (glucagon) , not energy storage (insulin). Usually in hot weather I will run first thing in the morning. This actually shortens my glucagon phase ascompared to running in the late afternoon. Usually if it ishot and I run early, I will try not to eat when I get backfrom the run until noon at the earliest. This gives me at least four or five hours in a glucagon state -higher energylevels and I get a lot more done. If you are going to eatearly in the day, it is best to eat low on the glycemic index.Organic fruit, carrot or celery sticks and fresh organicsalads are good choices.

You don't need to exercise to enter a glucagon state

Exercise can help to get you into a glucagon phase but is not necessary. All you really have to do is not go into an insulinstate by eating. Most of us are going to eat something duringmost days but it is optimal if you can limit the time of foodingestion to the mid-day hours, noon to 6:pm or so. You will have a good glucagon phase in the morning and not goto bed on a large load of insulin in the evening. As mentionedpreviously, hyperinsulinism is implicated in many of our serious lifestyle illnesses.

Dr. Roy Walford and caloric restriction

It may seem hard to believe, but during periods of starvationduring WWII, those who had their caloric intake reduced, had improvement in diseases such as heart disease and cancer.It was also noted that they did not age as much. This hasbeen studied by the late Dr. Roy Walford, who was part of theBiosphere. There is no question that calorically restrictedmice age much more slowly than those who are allowed to eatwhat they want. Dr. Walford also made the point that the calories that are eaten must be "nutritionally dense." Thisis also one of the premises of the MericleDiet. I don't want to suggest that one live a life of caloric restriction,but there is no doubt that reducing your caloric intake andnot eating as often or as much will improve your health and slow your aging.

Insulin Glucagon Aging

Somewhere in the basic premise of caloric restriction andretarded aging is the yin and yang of human energy management -Glucagon and Insulin. Too much of either is not good and as noted previously, most people in Americahave way too much insulin. If you want to feel better andlook better while you age more slowly, think glucagon,not insulin. Try to achieve "balance" between them. If you spend four hours a day in an insulin state, try to spend at least as much time in a glucagon state.

Conclusion

Understanding how glucagon and insulin affect your health and your weight is one of the most important concepts one can learn. Not only will you be able to work better, feelbetter and control your weight more easily, there now is impressive evidence that restricting your insulin secretionby reducing your frequency and quantity of feedings willretard aging.
