You can look up your reference body weight here or use the simple chart below to estimate your protein needs. In this case, height is a proxy for reference body weight.

Reference body weight is a way of estimating how much lean body mass a person of a specific height would have and thus how much protein they need on a daily basis. How do you know if you are getting grams? Read more about the unproven links between red meat and cancer in our guide on red meat and our guide on diet and cancer.

The following observational study found the opposite effect — vegetarians had a higher cancer rate than meat-eaters. However, it does raise the question of whether there can be dietary variables, more important than red meat consumption, that contribute to the risk of cancer.

It was thought that acidosis caused a loss of calcium from bone. But it is now recognized that the increase in urinary calcium excretion seen with high protein diets is likely due to increased intestinal absorption of calcium, as opposed to loss of calcium from bone.

The suggested mechanism for this is that amino acids are known to be used in the production of glucose via gluconeogenesis. However, well-conducted human trials show that dietary protein is not a meaningful contributor to blood glucose in healthy individuals or those with type 2 diabetes for important information about type 1 diabetes, see further below in this footnote.

Diabetes Dietary proteins contribute little to glucose production, even under optimal gluconeogenic conditions in healthy humans.

The trials included in this review of RCTs did not restrict protein intake and showed significant improvement in blood glucose levels and metabolic health. BMJ Open Diabetes Research and Care: Systematic review and meta-analysis of dietary carbohydrate restriction in patients with type 2 diabetes [strong evidence].

For people with type 1 diabetes, it is important to note that protein has been found to increase late post-meal blood sugars when consumed along with dietary carbohydrate. In the absence of dietary carbohydrate, protein amounts up to 50 grams do not seem to raise post-meal blood glucose, while grams of pure protein can raise blood glucose in a similar fashion to 20 grams of carbohydrate.

Nutrition Bulletin Micronutrient challenges across the age spectrum: Is there a role for red meat? The following are low-quality nutritional epidemiology studies that suggest a minimal increased risk with red meat intake or a lower risk with eating plant protein.

However, as we discuss in our guide on observational vs. experimental studies, this line of evidence is complicated by healthy user bias, poor data collection, confounding variables, and other methodological weaknesses. Journal of the American Heart Association The following observational study reports that eating more animal protein, but not plant protein, is associated with a higher risk of death in people ages 50 to The same correlation did not hold for those older than 65 years old.
