At the heart of it, weight loss and maintenance is rooted in a healthy mindful diet, regular exercise, and successful stress management. Yet, what do you do when you are already doing all of those things and the scale still refuses to budge? Firstly, I remind our patients that fitness, not fatness, predicts lifespan and chronic-disease-free years. If your genetics simply have given you a high BMI, but you are strong and fit, perhaps you should give yourself a break!

But if you are still trying to undo the “Covid-19lb” or have had changes in your metabolism or lifestyle patterns, we offer some tips and tricks to give you a competitive edge over your metabolism. Here is a partial list of some of our favorite medications and supplements.


Semaglutide is an exciting science-based strategy. Semaglutide is a GLP-1 agonist and was first approved in the U.S in 2017 as a method to improve glycemic control in patients with Type 2 diabetes. Recently, it has been shown that once weekly high-dose semaglutide injections are effective for patients who are having difficulty losing weight. It now carries a FDA indication as an adjunct to a reduced calorie diet and increased physical activity for chronic weight management in overweight or obese adult patients. The New England Journal of Medicine published the results of the STEP trial which revealed more than 50 percent of trial participants lost 15 percent of their body weight, and between 33 to 40 percent of participants lost 20 percent of their body weight. We’ve been using it with patients for a few years and most are very satisfied with the appetite surpression and weight loss.

Curious how it works? GLP-1 is a hormone produced in the small intestine that stimulates insulin secretion and inhibits glucagon secretion, thereby lowering blood sugar. It was first discovered in Gila Monster lizards! Newer, longer-acting GLP-1 agonists, like semaglutide, have a balanced effect on lowering post-meal glucose levels as well as fasting glucose levels. Additionally, it effectively decreases appetite and therefore reduces daily caloric intake. Read more here:

We offer a compounded version in which semaglutide is combined with vitamin B12. This combination has been shown in studies to assist with the tolerance of treatment with GLP-1 agonists. Two common adverse reactions associated with semaglutide are nausea and hypophagia. These reactions have been shown to be significantly reduced when used in conjunction with Vitamin B12.

People interested in adding this to their Science of Slim membership can consult with one of our doctors to find out if it is right for you.


Peptides are an exciting new tool to optimize weight loss and physical performance.


Commonly called our cuddle hormone, oxytocin has been shown to play a role in weight loss. It works primarily by decreasing appetite and increasing mood. It also has positive effects on sexual health, so for some it can be a great option. Learn the technical details here:


This approach to weight loss has fallen out of favor as more effective, better tolerated approaches have become available (such as semaglutide), but it works well for some and Dr. Oberg’s time-tested protocol works well. HCG is done for 40 days. For women, the diet is optimally started after menses begins, but as long as you are at least 10 days before next cycle, you can start. Men can start anytime.

The protocol is a little funny, but to make the program work, you have to follow it. For the first 3 days, you eat abundantly (expand stomach and increase triglycerides) and start taking HCG injections. Starting day 4, people follow a 500 calorie plan and do injections. After last injection on day 40, continue the restricted diet for 72 hours further. Then gradually increase calories while staying in ketosis (increase portion sizes or add 2 similar sized meals for 4 small meals per day).

Rev Up

VitaLab’s custom weight loss supplement, includes key science-based ingredients to support metabolism and hormone balance in a comprehensive way. The nutrients calm cortisol, to normalize fat metabolism, and stimulate basal metabolic rate to promote lean muscle and fat loss. Further, it helps balance blood sugar, thereby reducing cravings and helping you adhere to a low calorie healthy diet. We recommend pairing this with any weight loss approach you try.

If you prefer more of a mix-and-match approach, Ccinical studies have identified many nutrients and botanical medicines that can support weight loss – the trick is using the right ones for your individual situation.
