Considered one of my sufferers – who had been battling weight problems, uncontrolled diabetes and the price of her medicines – agreed in June 2019 to undertake a extra whole-food plant-based weight loss plan.
Excited by the problem, she did a exceptional job. She elevated her recent fruit and vegetable consumption, stopped consuming sweet, cookies and muffins and lower down on meals from animal sources. Over six months, she misplaced 19 kilos and her HbA1c – a measure of her average blood sugar – dropped from 11.5 to 7.6 %.
She was doing so properly, I anticipated that her HbA1c would proceed to drop and she or he can be one in every of our plant-based successes who had reversed diabetes.
Her three-month follow-up go to in March 2020 was canceled due to COVID-19 lockdowns. Once I finally noticed her once more in Might 2021, she’d regained a few of the weight and her HbA1c had climbed to 10.4 %.
She defined that her diabetes physician and a diabetes nurse educator had advised her that she was consuming an excessive amount of “sugar” on the plant-based weight loss plan.
She’d been suggested to restrict carbohydrates by chopping again on fruits and starchy greens and consuming extra fish and rooster. Sugar-free sweet, muffins, cookies and synthetic sweeteners had been inspired. Within the face of conflicting medical recommendation, she fell again on typical knowledge that “sugar” is dangerous and must be prevented every time potential, particularly you probably have diabetes.
I am a doctor, board licensed in preventive drugs with a lifestyle medicine clinic at Morehouse Healthcare in Atlanta. This rising medical specialty focuses on serving to sufferers make wholesome way of life habits modifications.
Sufferers who undertake whole-food plant-based diets improve carbohydrate consumption and infrequently see reversal of power illnesses together with diabetes and hypertension. In my scientific expertise, myths about “sugar” and carbohydrates are widespread amongst sufferers and well being professionals.
Fruit vs. sugar
Your physique runs on glucose. It’s the easy sugar that cells use for vitality.
Glucose is a molecular constructing block of carbohydrates, one of many three important macronutrients. The opposite two are fats and protein. Starches are lengthy, branching chains of glucose.

Naturally occurring carbohydrates journey in nutrient-dense packages equivalent to fruits, greens, entire grains, nuts and seeds.

People evolved to crave sweet tastes to get the vitamins wanted to outlive. A each day provide of vitamins, minerals and fiber is required as a result of our our bodies can’t make them. One of the best supply of those substances for our historic ancestors was candy, ripe, scrumptious fruit.
As well as, fruits comprise phytonutrients and antioxidants, chemical compounds produced solely by vegetation. Phytonutrients equivalent to ellagic acid in strawberries have cancer-fighting properties and promote coronary heart well being.
Refined sugars, however, are extremely processed and stripped of all vitamins besides energy. They are a concentrated type of carbohydrates. The meals trade produces refined sugars in lots of types. The commonest are sucrose crystals, which you’d acknowledge as desk sugar, and high-fructose corn syrup, which is discovered in lots of processed meals and sweetened drinks.
If you happen to regularly fulfill your style for candy with meals that comprise refined sugar – slightly than the nutrient-rich fruits on the core of this craving handed on by evolution – you may not get all the nutrients you need.
Over time, this deficit could create a vicious cycle of overeating that results in weight problems and obesity-related well being issues. Ladies who eat probably the most fruit tend to have lower rates of obesity.
Sugar toxicity
Refined sugars should not immediately poisonous to cells, however they’ll mix with proteins and fat in meals and within the bloodstream to provide poisonous substances equivalent to advanced glycation end products (AGEs). Excessive blood glucose ranges could produce glycated low-density lipoproteins. Excessive ranges of those and different glucose-related poisonous substances are related to an elevated danger of a variety of power well being issues, together with cardiovascular disease and diabetes.
The illness mostly related to sugar is Sort 2 diabetes. A shocking variety of individuals, together with well being professionals, incorrectly imagine that consuming sugar causes Sort 2 diabetes. This fantasy results in a deal with reducing blood sugar and “counting carbs” whereas ignoring the actual trigger: progressive loss of pancreatic beta cell function. At analysis, a affected person could have misplaced between 40 and 60 percent of their beta cells, that are liable for producing insulin.
Insulin is a hormone that controls how a lot glucose is within the bloodstream by blocking glucose manufacturing within the liver and driving it into fats and muscle cells. Lack of beta cell perform means not sufficient insulin will get produced, ensuing within the excessive blood glucose ranges attribute of Sort 2 diabetes.
Beta cells have low levels of antioxidants and are susceptible to attack by metabolic and dietary oxidized free radicals and AGEs. Antioxidants in fruit can defend beta cells. Researchers have discovered that consuming whole fruit decreases the risk of Type 2 diabetes, with those that eat the most fruit having the lowest risk.
Detoxing from sugar
Individuals enthusiastic about shedding weight and bettering well being usually ask if they need to do a “sugar detox”. For my part this can be a waste of time, as a result of it’s not potential to get rid of sugar from the physique. As an illustration, for those who ate solely baked rooster breasts, your liver would convert protein to glucose in a course of referred to as gluconeogenesis.
Low-carb diets could result in weight reduction, however on the expense of well being. Diets that considerably scale back carbohydrates are related to nutrient deficiencies and better risk of death from any cause. On low-carbohydrate ketogenic diets the body will break down muscles and switch their protein into glucose. The shortage of fiber causes constipation.
Eliminating meals sweetened with refined sugar is a worthy objective. However do not consider it as a “detox” – it must be a everlasting way of life change. The most secure option to go on a refined sugar “detox” is to extend your consumption of nutrient-dense vegetables and fruit. When you get rid of refined sugar, you may seemingly discover that your style buds turn into extra delicate to – and appreciative of – the pure sweetness of fruits.
