Can a simple habit really help lower blood sugar
“Most people think blood sugar control requires strict diets,” says Dr Saurabh. “But one simple habit can lower glucose almost as effectively as diet changes.” Who can benefit from this? Dr Sethi explains that it works for people with:
- Prediabetes
- Type 2 diabetes
- Fatty liver
- Insulin resistance
- Weight gain
- Belly fat
- Sugar cravings
What’s the easiest way to put this habit into practice
“A 10-minute walk after meals. Yes, just walking,” Dr Sethi reveals.
“Your leg muscles act like a sponge,” he explains. “When they move, they pull glucose directly out of your bloodstream. Less glucose in the blood means less insulin release. Less insulin means less fat being sent to the liver, which is particularly important for those with fatty liver.”
Benefits include:
- Smaller blood sugar spikes
- Lower insulin levels
- Reduced fat storage in the liver
- Less belly fat
- Fewer sugar crashes
- More steady energy
“You don’t need to walk fast, you don’t need step goals, and you don’t need a structured workout,” Dr Sethi says. “Even walking around your home works. One simple habit, no diets, no workouts, just walk for 10 minutes after meals and let your muscles lower your sugar naturally.”
