    Protein also invokes insulin spikes. Beef and yogurt cause insulin spikes similar to that of pasta. Insulin spikes in themselves aren't the cause of obesity.

    A high protein diet can make a person just as fat as one that's high in carbs granted the person doesn't regularly work out and lift weights (granted the person is inclined to store fat and/or has a low energy expenditure). Excess protein that does not get absorbed into the muscle tissue gets converted to glucose in the liver by the process of gluconeogenesis. It's pretty common knowledge, really. The only macronutrient that does not cause a marked insulin response is pure fat. As long as a person is not eating ungodly amounts of protein, its effects on insulin with regard to making you fat are negligible at best.

    And to claim that beef causes the same degree of insulin response as pasta is just moronic, as if to suggest that beef digests with the same speed as pasta.

    And no, insulin spikes in and of themselves are not the cause of obesity, but they are for probably more than half of the population which suffers from some degree of metabolic derangement and are overweight.

    Beef had a higher insulin score than brown pasta and white pasta and a score similar to that of grain bread (Table 4 in the research paper quote in the article), even though beef has a low glycemic index. Yogurt has an unusually high insulin score, greater than that of white bread. As with beef, some people assume yogurt does not spike insulin.

    It shows that insulin score doesn't necessarily correlate with glycemic index. A similar mistake can be made about blood glucose spikes by not considering glycemic load, which doesn't necessarily correlate with glycemic index. These are caveats for groups who are trying to use the concept of blood glucose spikes and insulin spikes in a superficial manner to promote a particular type of diet and aren't paying attention to all of the details.

    Insulin spikes in and of themselves are not a bad thing and are necessary for muscle growth. It's when insulin levels are kept at a constantly high level that it becomes a bad thing which leads to fat storage. When you eat meat there needs to be some insulin spike for the protein to be drawn into the muscle tissue. But the fact is that carbohydrates affect the blood sugar in a much bigger way since they digest so quickly. Protein needs to be broken down into glucose first by the liver via gluconeogenesis, which is a much slower process.
