The 7 Simplest Rules For Weight Loss

Use these seven rules to tap into the power of foods that can naturally slow sugar absorption, so you can keep eating meals you love

1） Have a Fatty Snack 10 to 30 Minutes Before Your Meals

Reason: You remain fuller longer

At the outlet of your stomach is a muscular ring, the pyloric valve. It regulates the speed at which food leaves your stomach and enters your small intestine. This valve is all that stands between the ziti in your stomach and a surge of glucose in your bloodstream. But you can send your pyloric valve a message to slow down.
Fat triggers a reflex that constricts the valve and slows digestion. As little as a teaspoon of fat—easily provided by a handful of nuts or a piece of cheese—will do the trick, provided you eat it before your meal.

2） Start Your Meal With a Salad

Reason: It soaks up starch and sugar

Soluble fiber from the pulp of plants—such as beans, carrots, apples, and oranges—swells like a sponge in your intestines and traps starch and sugar in the niches between its molecules. Soluble means "dissolvable"—and indeed, soluble fiber eventually dissolves, releasing glucose. However, that takes time.
The glucose it absorbs seeps into your bloodstream slowly, so your body needs less insulin to handle it. A good way to ensure that you get enough soluble fiber is to have a salad—preferably before, rather than after, you eat a starch.

3）Have Some Vinegar

Reason: It slows the breakdown of starch into sugar

The high acetic acid content in vinegar deactivates amylase, the enzyme that turns starch into sugar. (It doesn't matter what kind of vinegar you use.) Because it acts on starch only, it has no effect on the absorption of refined sugar. In other words, it will help if you eat bread, but not candy. But there's one more benefit: Vinegar also increases the body's sensitivity to insulin. (Search:Why is insulin important to the body?)

You should consume vinegar at the start of your meal. Put it in salad dressing or sprinkle a couple of tablespoons on meat or vegetables. Vinegar brings out the flavor of food, as salt does.

4）Include Protein With Your Meal

Reason: You won't secret as much insulin

Here's a paradox: You want to blunt insulin spikes—but to do that, you need to start secreting insulin sooner rather than later. It's like a fire department responding to a fire. The quicker the alarm goes off, the fewer firefighters will be needed to put out the blaze.

Even though protein contains no glucose, it triggers a "first-phase insulin response" that occurs so fast, it keeps your blood sugar from rising as high later—and reduces the total amount of insulin you need to handle a meal. So have meatballs with your spaghetti

5）Eat Lightly Cooked Vegetables

Reason: You digest them more slowly

Both fruits and vegetables contain soluble fiber. As a rule, though, vegetables make better sugar blockers, because they have more fiber and less sugar.

But don't cook your vegetables to mush. Boiling vegetables until they're limp and soggy saturates the soluble fiber, filling it with water so it can't absorb the sugar and starch you want it to. Also, crisp vegetables are chunkier when they reach your stomach, and larger food particles take longer to digest, so you'll feel full longer. Another tip: Roasted vegetables like cauliflower can often serve as a delicious starch substitute.

6）Have A Glass Of Wine With Dinner

Reason: Your liver won't produce as much glucose

Alcohol has unique sugar-blocking properties. Your liver normally converts some of the fat and protein in your blood to glucose, which adds to the glucose from the carbs you eat. But alcohol consumed with a meal temporarily halts your liver's glucose production. A serving of any alcohol—beer, red or white wine, or a shot of hard liquor—will reduce the blood sugar load of a typical serving of starch by approximately 25%.

That doesn't mean you should have several drinks (especially if you have diabetes, as multiple drinks can cause hypoglycemia). Not only does alcohol contain calories, but it also delays the sensation of fullness, so you tend to overeat and pile on calories. Be especially mindful about avoiding cocktails that are made with sweetened mixers—yet another source of sugar.

7）Eat Sweets For Dessert Only

Reason: All of the above

If you eat sweets on an empty stomach, there's nothing to impede the sugar from racing directly into your bloodstream—no fat, no soluble fiber, no protein, no vinegar.
But if you confine sweets to the end of the meal, you have all of the built-in protection the preceding rules provide. If you want to keep blood sugar on an even keel, avoid between-meal sweets at all costs—and when you do indulge, don't eat more than you can hold in the cup of your hand. But a few bites of candy after a meal will have little effect on your blood sugar and insulin—and can be quite satisfying.
