Weight loss: what is the glycemic index of potato chips?

Self-tutoring about weight loss and health: the tutor gets specific about the GI of one of his guilty favourites.

Potato chips: glycemic index (GI): approx 54

In my post from June 16, 2017 I mention that a rating of ≤55 is low.

Apparently, potato chips have low glycemic index:)

Weight loss: does dietary fat help burn fat?

Self-tutoring about diet and weight loss: the tutor investigates the idea that eating fat helps burn fat.

Although the idea that eating fat helps fat loss might seem surprising, it’s apparently valid, provided the eater subtracts carbohydrates to accommodate increased fat intake.

A few reasons are proposed for why eating fat (rather than carbohydrates) can help lose fat:

  1. Eating fat can increase the rate at which the body burns calories.
  2. Eating fat for energy, rather than carbohydrates, decreases insulin levels. Higher insulin levels prevent fat burning, while low levels of it promote fat burning.
  3. Your predominant energy food becomes the one your body predominantly runs on. If it’s fat, your body’s hormones adjust to use it – both incoming and stored.

It could be mentioned here that some fats are better than others. I’ve come to believe that trans fats are to be avoided. (I also try to avoid processed snacks.) However, whether fat is dairy or vegetable oil matters little to me. Some people have more specific opinions.

Rest calorie burn rate

Self-tutoring about health: the tutor pursues the idea of how many calories a person might burn per minute, at rest.

The rest calorie burn rate is approximately 1.2 per minute for a person of mass 70kg.

Back in my post from August 16, 2017, I reported 80 to 100 Watts as the power needed to stay alive. Taking 90W as the average, it leads to 1.3cal/minute.

When discussing fitness, the calories mentioned are nutritionist calories. In physics, 1 nutritionist’s calorie=1kcal.

Lifestyle: calorie-wise desserts: fruitcake?

Maintaining calorie consciousness means constant self-tutoring. The tutor shares that fruitcake may be surprisingly calorie wise.

My wife brought home a fruitcake a couple of days ago. I’m the only one of our family who likes fruitcake, but since I’m trying to lose a few pounds, I was a bit worried. Would eating the fruitcake stall my weight loss? Not necessarily.

The fruitcake she bought is by Weston Bakeries, out of Toronto. It’s topped with pecans but not iced. Per 83g, it carries 280 calories.

By way of comparison I looked at a bagel with margarine. The bagel is 190 calories (for 75g). Next, a teaspoon of margarine we buy carries 35 calories and has mass 4.5g. I can easily imagine putting a teaspoon of margarine on each half of a freshly toasted bagel. That brings the toasted bagel, with the margarine, to 260 calories, and 84g.

So, gram for gram, the fruitcake is about 20/260, or 8%, more calorie dense than a toasted bagel with margarine.

The reason the fruitcake is (to my mind, anyway) surprisingly low in calories is that it’s less than 10 percent fat.

I’ll eat the fruitcake, little by little:)

Diet and weight loss: Is the banana to be avoided if you want to lose weight?

Dieting, I’m constantly self-tutoring. The tutor shares, to him, a surprising find about the calories in a banana.

banana beside three Easter eggs:  same calorie value!

Easter can be a challenging time for someone on a diet. Putting out eggs last night, I gave in to temptation and ate a few, then checked the wrapper for an idea about the consequences. The kind of Easter egg in the photo above is about 6.5g, 33.33 calories each. Therefore, three of those eggs together are worth 100 calories – about the same as the banana.
