There’s no sugar-coating it: All calories are not created equal – Harvard Health Blog
By choosing the low-glycemic foods and thus the minimally processed foods, people can lose more weight, feel fuller longer, and remain healthier.

Flawed and corrupted science is the reason we all grew up thinking that fat is bad for us. The low-fat craze that still persists today began with a 1967 study funded by the Sugar Research Foundation (SRF) and published in the most prestigious medical journal in the world, The New England Journal of Medicine.
The doctors who authored that study were paid by the SRF (about $50,000 in today’s dollars) to only include evidence that fat, not sugar was the major cause of weight gain and heart disease.
It turns out that the opposite is true, and 50 years later America’s obesity epidemic is living proof of what happens when you substitute sugar and refined carbohydrates for fat in your diet.
The reason is that sugar has important effects on your metabolism and hunger.
- It causes insulin resistance and spikes, which make you store more fat
- Its breakdown by the liver results in the accumulation of deep belly fat
- The sugar crashes caused by insulin make you hungry sooner and contribute to overeating
According to Dr. David Ludwig, Nutrition Professor at Harvard, “Overall, these processed carbohydrates are worse than the fats they replaced”.
According to the Harvard blog, doctors are now focusing on categorizing carbohydrates by an index that quantifies their effect on your insulin and blood sugar levels. This index is determined by several factors, including the sugar content and how refined and processed it is. Refined carbs are usually stripped of fiber and other nutrients. That is why you should ideally satisfy your sweet tooth with fruit from the produce section instead of packaged and baked goods. Think about it – you can make a batch of cookie dough as sweet as you want, but nature has a built in limit on the sugar content of fruit in proportion to its other nutrients. Also, avoid boxed cereal and eat whole grains instead. Finally, healthy fats (like avocado, olive oil, and almonds) are good for you. It’s the “fat-free” packaged goods that are killing you.
