How to Avoid Ozempic Face, Lose More Belly Fat, and Be Healthier

“Ozempic face”, “Ozempic arms” and similar monikers describe the skin sagginess and hollowed-out facial features that result from losing weight quickly with Ozempic and other GLP-1 agonists (mimickers). Time-restricted eating (TRE), also called intermittent fasting, rivals Ozempic and other GLP-1 agonists like Wegovy or Mounjaro for healthy weight loss and maintaining a healthy appearance. GLP-1s cause weight loss primarily by throttling digestion and suppressing the appetite. TRE causes weight loss primarily through metabolic switching of the body’s tendency to burn glucose (sugar) for energy, to burning fat for energy. 

TL;DR

See both tables below for the results of Ozempic vs time-restricted eating (TRE) and for TRE vs low-carb diets.

Weight loss due to time-restricted eating preferentially reduces belly fat whereas GLP-1 agonists actually target subcutaneous fat – ie, the kind that keeps your face looking youthful. A recent study showed not just an impressive reduction in visceral fat (fat around organs contributing to belly bulge) and weight loss in general, but also showed improvement in many risk markers for cardiovascular and metabolic health by simply limiting food intake to within an 8-hour period per day. Results were amplified if a low-carbohydrate diet was followed, except for waist circumference reduction, which was actually greater without the low-carb diet! 

Burn fat, boost energy & balance hormones

Another way that TRE gives better outcomes than GLP-1s is by preserving lean muscle mass and skin structural integrity. It has been reported that as much as 40% of the weight loss from using GLP-1 agonists is actually lean mass (primarily muscle mass). Muscle loss results in a slower metabolism, effectively worsening the body’s ability to maintain a healthy weight in the future. Muscle loss is essentially body wasting and further contributes to facial thinning, often resulting in an unhealthy, gaunt appearance. With TRE, there is no associated muscle loss (assuming nutrition remains adequate and exercise is not reduced) which results in maintaining a more attractive body and face. Rapid weight loss as is seen when using GLP-1 agonists, often results in excessively loose, sagging skin. However, intermittent fasting reduces skin glycation (an aging process), stimulates collagen production and triggers autophagy (leading to cellular regeneration) – all of which help preserve skin thickness and elasticity.

Side Effects

Support healthy weight-loss naturally

Although both GLP-1 agonists such as Ozempic, and intermittent fasting appear to balance blood sugar, they do so in opposite ways. GLP-1 agonists reduce blood sugar by stimulating the pancreas to release more insulin. When patients come off of GLP-1 agonists, their blood sugar and insulin resistance typically reverts as does weight gain. Conversely, TRE manages blood sugar by innately reducing insulin resistance for long term health benefits. High insulin sensitivity is associated with many health markers such as cardiovascular health and reduced cancer risk.

Because these two different processes work in such different ways,  the effects and long-term outcomes are also vastly different. GLP-1 agonists suppress the body’s natural functioning while TRE enhances it. Side effects of GLP-1 agonists range from mild to severe and include gastrointestinal dysfunction, thyroid tumors (in animal studies), pancreatic inflammation, emotional flatness and other negative mood effects, and long-term reduced ability to maintain healthy weight. Conversely, TRE has been shown to improve gut microbiota (in animal studies), improve thyroid hormone balance, boost mental clarity, enhance stress response and increase feel-good neurotransmitters such as serotonin. The health benefits of TRE enhance long-term metabolic outcomes rather than suppress them. In addition to the mental and emotional effects of these two disparate weight-loss processes, it is also fascinating to discover that the act of using a “quick fix” vs using self-control to affect desired bodily changes have opposite psychological effects as well. By avoiding the practice of self-control, the prefrontal cortex (executive functioning and emotional regulation) is not exercised and management is given over to the subcortical areas allowing impulsivity and strengthening the mind’s tendency to make poor choices and bad habits. Exercising the prefrontal cortex by using self-control required to limit eating to certain hours (or any other healthy lifestyle habit), strengthens discipline and leads to better self-mastery and a deeper connection to ourselves. A final benefit is that TRE is free while GLP-1 agonists are expensive.
