Just today, I/m not going to eat between meals and I’m not going to take seconds. And I’ll use the tools and guidance from The Hacker’s Diet to help me reach (and keep) my goal.

Did you know that a large Sonic Strawberry Milkshake has 860 calories and 143 carbohydrates? And their large Blasts range from 900 to 980 calories (carbs are somehow just about 140 for all.)

Those Sonic commercials with the couple that has the funny arguments as they order and eat large ice cream treats are my favorite commercials this summer. But, they’re advertising early death as near as I can tell (even the ‘Regular’ shakes have 500 to 600 calories. And the ‘Regular’ Blasters? Almost 700.) Sonic’s ads are on all the time, they must be effective. Who is eating these things? And how often do they have them?

How do we know if the Shake is worth it? Most people aren’t closely monitoring their calories. And they aren’t weighing themselves every day. So the effects of a Sonic milkshake are obscured by the extravagant meals they’re eating — that we’re all eating if we don’t make a conscious effort to control ourselves.

I’ve noticed that since I’ve been posting my weight in The Hacker’s Diet Weight Log that my attitude toward food has changed. Lately I have more of a sense of cost/value about what I eat. And it’s because I know exactly how the food I eat will affect the trendline of my real-weight.

I’m not saying that I’ll never have a milkshake again. But (even ignoring the impact of 140 carbohydrates on a diabetic), I just don’t think it’s worth 900 calories. If I get one at all, I think I’ll split it with at least a couple of friends.
