Your body can make all the sugar it needs, even when you're doing intense exercise like marathon training, so you don’t actually have to eat carbs to stay healthy.

Type 2 diabetes means your blood sugar stays too high over time, and doctors check this with two tests: one after you've fasted and another called HbA1c that shows how much sugar has been sticking to your red blood cells over the past few months.

If your body is healthier and your red blood cells live longer, your HbA1c blood sugar test might show higher levels — not because your blood sugar is high, but because the sugar has more time to stick to older red blood cells.

Eating only animal foods might reduce body-wide inflammation, keep blood sugar steady, and give you lots of important nutrients—all of which could help your metabolism work better.

If your red blood cells live longer, they soak up more sugar over time, which can make your HbA1c blood test go up — even if your average blood sugar hasn't actually changed.

If your red blood cells live longer or shorter than average, your A1C test might not give a true picture of your average blood sugar levels.

HbA1c shows how much sugar has been sticking to your blood cells over the past few months — it's like a long-term blood sugar report card.

People with obesity and type 2 diabetes stick to intermittent fasting better than time-based eating windows — 85% stayed with it versus 78% — over four months, even though both plans cut the same amount of calories.

If you have obesity and type 2 diabetes, cutting calories in different ways—like fasting sometimes, eating only during certain hours, or eating less every day—can lower your blood sugar about the same amount over four months.

If you have obesity and type 2 diabetes, cutting calories in cycles (like fasting some days) might lower your blood fat levels more than other diet plans over four months.

Eating fewer calories on some days (intermittent restriction) seems to make the body use insulin better—by a noticeable amount—than other dieting styles for people who are overweight and have type 2 diabetes.

If you have early type 2 diabetes and obesity, cutting calories intermittently—like fasting some days—might lower your blood sugar more than other diet plans, by about 2.3 points on average in 4 months.

About half of the people who finished a 12-week diet program were still sticking to their diet plan six months later, whether it was eating within a certain time window or cutting calories.

People with obesity who kept up either time-restricted eating or cutting calories on their own after a 12-week program didn’t gain much weight back over the next 3 to 6 months.

People staying on a low‑calorie diet say they’re more aware of what they eat and portion sizes, yet they also feel anxious about counting food, get stronger cravings, and sometimes binge eat.

People who keep eating only within a set time window say they sleep better, feel more energetic during the day, and have happier digestion, but they also notice they get hungry in the morning and find it hard to fit the eating schedule into work or family life.

People were just as likely to tell others to try either the eating‑window plan or the calorie‑cut plan.

People stuck with time-restricted eating and calorie cutting about the same amount after their supervised program ended — neither one was clearly better for long-term follow-through.

People with obesity who tried time-restricted eating kept their weight steady after finishing the program, but those who cut calories lost about 1.6 kilos a month later—though they gained it back within three months.

Both intermittent fasting and cutting calories every day can be hard to stick to and may not be safe for everyone with type 2 diabetes, so neither is a perfect solution—this is based on the abstract summary—full study details were not available.

Cutting calories steadily over time might help people with type 2 diabetes improve their metabolism in the long run — like lowering belly fat and helping the body use insulin better — even if the scale or blood sugar doesn’t change much at first.

Skipping meals now and then might lower blood sugar and weight faster than just eating fewer calories all the time for people with type 2 diabetes.

This finding is from the abstract summary - full study details were not available. It means that while intermittent fasting can help with weight and metabolism, it doesn't work better than just eating fewer calories every day when comparing equal calorie levels.

Eating fewer calories each day seems to make adults feel less hungry and less tired than doing the same amount of calories in an intermittent‑fasting pattern, so it might be easier for some people.
