Quite simply, this day fell apart because in my commitment to not eating between meals, my blood sugar dropped precipitously low. I either need to have a lot more in my meals to hold me 4-5 hours, or I need to learn what snacks are low in calorie and high in energy. I get so run down about 2-1/2 to 3 hours after eating. There’s a lot I need to learn.

Hi there. I ran across this post and it caught my eye. I have diabetes and I know that low blood sugar is nothing to fool with. If you are trying to lose weight, only eating every 4-5 hours could actually be hurting your chances. What happens when you go long periods between eating is that your body goes in to “starvation mode” wherein it will automatically store a lot of the food you eat as fat because it thinks you have an unreliable food source. It’s a self-preservation mechanism that’s built in to our bodies. By eating small meals every 3 hours, your body realizes that that food sourcing is not an issue and will release fat deposits to use as energy. Also hydration plays a big part in this equation too. A good rule of thumb is to divide your weight by two. That is the number of ounces of water you should be drinking per day. I guarantee that if you at least try to drink more water and eat smaller (around 200-300 calorie) meals every 3 hours that within a week, your metabolism will increase regardless of your age.
