Focus on low glycemic index foods: While reducing fat and increasing fiber can significantly improve insulin sensitivity, low glycemic index (GI) foods reduce after-meal blood glucose levels. Low GI foods include pumpernickel or rye bread, oats, beans, bran cereals, most fruit, and sweet potatoes, compared to higher GI foods such as white potatoes, processed foods, and cold cereals.
Formal recommendations on how to reverse type 2 diabetes in clinical practice must await further studies. In the meantime, it will be helpful for all individuals with newly diagnosed type 2 diabetes to know that they have a metabolic syndrome that is reversible. They should know that if it is not reversed, the consequences for future health and cost of life insurance are dire, although these serious adverse effects must be balanced against the difficulties and privations associated with a substantial and sustained change in eating patterns. For many people, this may prove to be too high a price to pay, but for those who are strongly motivated to escape from type 2 diabetes, the new understanding gives clear direction. Physicians need to accept that long-term weight loss is achievable for a worthwhile proportion of patients (96). In the United States, diabetes costs $174 billion annually (97), and in the United Kingdom, it accounts for 10% of National Health Service expenditure. Even if only a small proportion of patients with type 2 diabetes return to normal glucose control, the savings in disease burden and economic cost will be enormous.
Chronic exposure of β-cells to triacylglycerol or fatty acids either in vitro or in vivo decreases β-cell capacity to respond to an acute increase in glucose levels (57,58). This concept is far from new (59,60), but the observations of what happens during reversal of diabetes provide a new perspective. β-Cells avidly import fatty acids through the CD36 transporter (24,61) and respond to increased fatty acid supply by storing the excess as triacylglycerol (62). The cellular process of insulin secretion in response to an increase in glucose supply depends on ATP generation by glucose oxidation. However, in the context of an oversupply of fatty acids, such chronic nutrient surfeit prevents further increases in ATP production. Increased fatty acid availability inhibits both pyruvate cycling, which is normally increased during an acute increase in glucose availability, and pyruvate dehydrogenase activity, the major rate-limiting enzyme of glucose oxidation (63). Fatty acids have been shown to inhibit β-cell proliferation in vitro by induction of the cell cycle inhibitors p16 and p18, and this effect is magnified by increased glucose concentration (64). This antiproliferative effect is specifically prevented by small interfering RNA knockdown of the inhibitors. In the Zucker diabetic fatty rat, a genetic model of spontaneous type 2 diabetes, the onset of hyperglycemia is preceded by a rapid increase in pancreatic fat (58). It is particularly noteworthy that the onset of diabetes in this genetic model is completely preventable by restriction of food intake (65), illustrating the interaction between genetic susceptibility and environmental factors.
When you have type 1 or type 2 diabetes, you need to be very aware of not only what you eat, but also when and how much you eat. A Certified Diabetes Educator (CDE) at Joslin can work with you to develop a healthy meal plan that fits your lifestyle. Following a meal plan can also help you lose weight and lower your risk of developing complications.
In addition to walking and stretching exercises, try interval training cardio, like burst training, or weight training three to five days a week for 20–40 minutes. Burst training can help you burn up to three times more body fat than traditional cardio and can naturally increase insulin sensitivity. You can do this on a spin bike with intervals, or you can try burst training at home.
Greek clover is an annual herb with aromatic seeds having medicinal properties. It is also known as fenugreek, and is largely used in curry. Greek clover has properties to lower down the levels of glucose in the body, which, in turn, controls diabetes. Also, when given in changeable doses of 25 gm to 100 gm on a daily basis, it was found to diminish reactive hyperglycemia in diabetic patients. Furthermore, levels of glucose, serum cholesterol, and triglycerides were also appreciably reduced. Alternatively, one can just stir two teaspoons of Greek clover seeds in powder form in warm milk and consume on a regular basis; it will control the levels of blood sugar and keep diabetes at bay. In case one does not want to have the powder in milk, seeds can be eaten wholly, too.
Conventional cow’s milk: Conventional cow’s milk and dairy products should be eliminated, especially for people with type 1 diabetes. Dairy can be a fantastic food for balancing blood sugar if it comes from goat’s, sheep or A2 cows. But stay away from all other forms of dairy because the A1 casein produced by conventional cows will harm the body and trigger an immune response similar to gluten. When buying dairy, only purchase raw and organic products from pasture-raised animals.
The American Diabetes Association publishes treatment guidelines for physicians based on all available scientific evidence. In the 2018 guidelines document, Standard of Medical Care in Diabetes, the ADA states that there is not sufficient evidence to support the use of any of the proposed alternative treatments for diabetes. These guidelines state that:
For people with either type of diabetes, exercise can lower the chance of having a heart attack or stroke and can improve circulation. It may offer stress relief, as well. People with type 2 diabetes who need to lose weight can benefit from moderate exercise. Most people with diabetes are encouraged to get at least 150 minutes each week of moderate-intensity aerobic physical activity, like walking. Strength training is often recommended at least twice a week. Talk to your doctor about what type of exercise is right for you.
Vitamin C may make up for low blood levels of insulin, which normally works to help cells absorb the vitamin. Proper amounts of vitamin C may help the body maintain a good cholesterol level and keep blood sugar levels under control. But too much can cause kidney stones and other problems. Check with your doctor to see if a vitamin C supplement is right for you.
The more intense the exercise, the better. According to the British diabetes association diabetes.co.uk, high-intensity interval training (HIIT) may be better for weight loss and glucose control than continuous aerobic activity like jogging. HIIT involves alternating between short bursts of increased intensity exercise and rest — for instance, running and then walking on and off throughout the workout.

However, the observation that normalization of glucose in type 2 diabetes occurred within days after bariatric surgery, before substantial weight loss (15), led to the widespread belief that surgery itself brought about specific changes mediated through incretin hormone secretion (16,17). This reasoning overlooked the major change that follows bariatric surgery: an acute, profound decrease in calorie intake. Typically, those undergoing bariatric surgery have a mean body weight of ∼150 kg (15) and would therefore require a daily calorie intake of ∼13.4 MJ/day (3,200 kcal/day) for weight maintenance (18). This intake decreases precipitously at the time of surgery. The sudden reversal of traffic into fat stores brings about a profound change in intracellular concentration of fat metabolites. It is known that under hypocaloric conditions, fat is mobilized first from the liver and other ectopic sites rather than from visceral or subcutaneous fat stores (19). This process has been studied in detail during more moderate calorie restriction in type 2 diabetes over 8 weeks (20). Fasting plasma glucose was shown to be improved because of an 81% decrease in liver fat content and normalization of hepatic insulin sensitivity with no change in the insulin resistance of muscle.
There are many studies showing that by initialing lose 5% of current body weight and getting 150 minutes of exercise weekly can and do return many folks’ blood glucose levels back into a normal range. However we must continue these actions as lifestyle changes, not just a means to an end. The human body is incredible forgiving and will always move towards health when given the opportunity to do so.
Exenatide (Byetta) was the first drug of the GLP-1 agonist group. It originated from an interesting source, the saliva of the Gila monster. Scientists observed that this small lizard could go a long time without eating. They discovered a substance in its saliva that slowed stomach emptying, thus making the lizard feel fuller for a longer time. This substance resembled the hormone GLP-1.
