Most individuals with metabolic syndrome have insulin resistance, which implies the cells within the physique do not reply to insulin. Their blood sugar stays excessive, which might result in the event of sort 2 diabetes. One in three folks over the age of 20 have metabolic syndrome.

Individuals with diabetes additionally usually expertise these blood sugar spikes after meals, which might result in issues. One in 5 folks have no idea they’ve the illness.

There is not sufficient analysis on blood sugar responses in wholesome people, in response to Sarah Berry, a lecturer at Kings School London and chief scientist at ZOE. Many individuals who’ve by no means been recognized with prediabetes or diabetes might expertise blood sugar spikes that attain into the diabetic vary.

A excessive spike in glucose in response to carbohydrate consumption could cause irritation. When these spikes are extreme and repeated, they contribute to continual hostile low-grade irritation, atherosclerosis and beta-cell degeneration, and may result in weight acquire. These elements are related to an elevated threat of creating weight problems, sort 2 diabetes, heart problems and different metabolic ailments.

Doing seated calf raises, known as soleus push-ups, may enhance blood sugar management.
