The plan hinges on the idea of regaining control of your metabolic health, including making your metabolism “more efficient,” addressing insulin resistance (insulin is a hormone that regulates the amount of glucose in the blood, and insulin resistance is a hallmark of prediabetes and type 2 diabetes), and balancing hormones (such as hunger and stress hormones). The first element, insulin resistance, appears to be the most important target of the program. The company states on its website that the dietary supplement stops weight gain and is able to “reverse insulin resistance” so your body can “release stored fat.” But it’s likely not necessary to take a supplement in order to improve insulin sensitivity. According to the Centers for Disease Control and Prevention (CDC), reversing insulin resistance involves increasing physical activity, losing weight, avoiding high blood sugars, managing stress, and sleeping adequately. Golo makes some really big medical claims, including that its customers have reported fewer symptoms of PCOS (polycystic ovary syndrome), have been cured of prediabetes or type 2 diabetes, and have lowered their blood pressure and cholesterol. With a focus on whole foods, there’s less of a reliance on processed foods, and that on its own can be a boon to your health. Cassetty points to a study published May 16, 2019, in Cell Metabolism that suggests this way of eating may be favorable to weight loss. The study was small (consisting of only 20 adults), but for two weeks participants ate either an ultra-processed or unprocessed diet. Then they switched diets for another two weeks. When eating processed fare, participants consumed 500 more calories (from carbs and fat) than the fresh-food dieters, and gained about two pounds. As for those on the diet with fresh food? They lost two pounds. “People who eat processed foods don’t fill up as quickly and eat faster, so they consume more food,” says Cassetty.

It is touted as a weight loss supplement that prevents insulin levels from rising. Limited evidence shows that Banaba leaf extract may be used to lower blood glucose levels in people with diabetes. Rhodiola rosea is a flowering plant that may impact cells that store fat, particularly in the midsection, per a study. Still, this preliminary research is not solid evidence that this type of supplement — or any weight loss supplement — is a silver bullet. “There has never been a supplement to materially and meaningfully boost your weight loss for any sustainable or long-term period,” says Cassetty. What’s more, there are potential safety issues with the Release supplement. “I’m a bit concerned with the supplement,” says Emmaline Rasmussen, RDN, the owner of Sound Nutrition in Chicago. She suggests that anyone interested consult a physician and registered dietitian before trying the Golo diet, especially those who are managing diabetes. “Diabetes may be regulated with medication, and it can be potentially dangerous to start a diet that claims to impact insulin levels without medical supervision,” she says. While the company claims the supplement is safe to take with medications, at the very least you’ll want to ask your healthcare team if your meds should be adjusted. (The company notes that Release may lower blood sugar, so certain medications may need to be adjusted.) You may also be taking medication for high blood pressure, a condition that this diet claims to improve. In that case, your doctor should keep tabs on any progress and assess if your prescription needs to be adjusted in any way. Also, keep in mind that in general, the U.S. Food and Drug Administration (FDA) doesn’t regulate supplements the way they do conventional medications. Namely, the FDA does not test supplements before they’re marketed — that responsibility falls to the supplement makers. A small randomized, double-blind, placebo-controlled study on Golo appeared in the peer-reviewed journal Trends in Diabetes and Metabolism in May 2019 and is linked on the company’s website. Consisting of 68 participants, those who followed the Golo diet and took Release lost about 13 pounds over 13 weeks, compared with the placebo group that lost about 7.5 pounds. For perspective, however, keep in mind that the study was small and 13 weeks is short-term results — it’s not clear what happened to these participants after three months. (Essentially, it’s easy to lose weight on any diet if you follow it for that short of a time period.) Note, though, that this study was funded by the Golo company, so there is a possible conflict of interest. It’s easy to find a number of rave reviews on their website, with people displaying their “before” and “after” bodies. “This promotes an idea that there’s one look to health, but bodies come in a lot of different sizes, and healthy does not have a look,” Cassetty says. How much Release you purchase appears to be tied to how much weight you’d like to lose. This is what’s currently listed on their website:
1 bottle of Release, to lose 10–20 pounds (lb): $59.952 bottles of Release, to lose 21–40 lb: $99.903 bottles of Release, to lose 41–60 lb: $119.85
What to Eat
According to the website, foods that are encouraged are:
ButterEggsWhole milkCheeseGreek yogurtFruitsVegetablesGrains, including bread and pastaChickenFishSteakNuts
What to Avoid
There are few restrictions beyond focusing on nutrient-dense whole foods. People are also encouraged to avoid highly processed products like diet shakes, bars, and meal replacements and to limit or avoid heavily refined and processed foods and snacks in general. Breakfast 1 fat, 2 proteins, 2 carbohydrates, 1 vegetable Lunch 1 fat, 2 proteins, 1 carbohydrate, 2 vegetables Dinner 1 fat, 1 protein, 1 carbohydrate, 2 vegetables One overarching idea is to spend one to two hours per week on meal prep. You can then prepackage containers with foods in their correct ratios and grab and go throughout the week. Doing it this way means you’ll likely repeat meals and foods throughout the week. Breakfast 2 hard-boiled eggs, overnight oats made with zucchini, chia seeds, and coconut flakes Lunch Chicken, salad greens, sweet potatoes, and coconut oil Snack Celery sticks Dinner Chicken, broccoli cooked in coconut oil, sweet potatoes If you are interested in trying the Golo diet, this is the website you’ll be using frequently. Not only can you find information about the diet itself, additional resources like their blog, but you can also sign up to purchase the Golo for Life plan and supplements. National Center for Complementary and Integrative Health A key cornerstone of the Golo diet is their metabolic supplement, which contains various herbal ingredients. For more information about how the ingredients work and the scientific data (or lack thereof) behind them in terms of insulin function and weight loss, you can use the NCCIH’s various databases, as well as learn how to stay safe when using complementary medicine. Nutrition.gov When you’re starting out on your journey to lose weight for the first (or fifth time), it’s helpful to read through verified resources, which will give you the knowledge and support you need to be successful. Nutrition.gov cuts through the chatter of diet programs and provides additional resources on Selecting a Weight Loss Program, Choosing a Safe and Successful Weight-Loss Program, and What You Should Know About Popular Diets, as well as shopping lists, menus, how to eat healthy while dining out, and info about incorporating exercise into your plan.
Best Books
Insulin Resistance Diet for Beginners Though this well-rated book is not specific to the Golo diet, it centers itself around the mission of the plan: Reversing insulin resistance. Written by the registered dietitian Marlee Coldwell, RD (now Marlee Hamilton), the book lays out a doable plan for managing blood sugar, shopping guidelines, and quick and easy meals (for example penne with sausage and kale, grilled peach and prosciutto pizzas) to make it all happen.
