"Anytime you’re stressed, you probably go for food," Dr. Seltzer says. (Have we met?!) That’s because cortisol, the stress hormone, stokes your appetite for sugary, fatty foods. No wonder it’s associated with higher body weight, according to a 2007 Obesity study that quantified chronic stress exposure by looking at cortisol concentrations in more than 2,000 adults’ hair.
Used on a short-term basis clinically to treat obesity, some appetite suppressants are also available over-the-counter. Most common natural appetite suppressants are based on Hoodia, a genus of 13 species in the flowering plant family Apocynaceae, under the subfamily Asclepiadoideae. Several appetite suppressants are based on a mix of natural ingredients, mostly using green tea as its basis, in combination with other plant extracts such as fucoxanthin, found naturally in seaweed. Drugs of this class are frequently stimulants of the phenethylamine family, related to amphetamine (informally known as speed).
Dr. Kohnke and his team then tested thylakoid in humans and found that it also acts as a natural appetite suppressant in normal-weight people. Eleven subjects ate a high-fat meal (a sandwich with thylakoid-rich pesto or regular pesto). Afterwards, levels of three different appetite signaling hormones were altered in those given the thylakoid-rich sandwiches. Two hours after the meal, they showed significant increases in the satiety hormone cholecystokinin compared to those who did not eat a thylakoid-rich sandwich. They also had reduced levels of the hunger hormone ghrelin, a hormone secreted by adipose tissue (fat cells) that tells you you’re hungry. Six hours after the meal, they had significant increases in ghrelin’s opposite hormone—leptin—which also control’s appetite by telling you you’re full. The fact that thylakoid increased leptin levels in the blood six hours after eating is important because leptin is crucial for regulating calorie intake between meals and over longer periods of time.
Soy products can be the easiest and most convenient “go-to” items when transitioning to a vegan diet. Soy isn’t necessarily unhealthy, but it is imperative that attention be paid to the amount of processed products in a meal plan. For instance, a tofu scramble for breakfast, soy veggie burger for lunch, and pad Thai with tofu for dinner is excessive. Instead, choose vegan cheese made with nuts, a black bean burger, or a pad Thai with vegetables and tempeh for whole-food versions of your favorite foods.
Research says the chemical EGCG found in green tea that speeds up the body’s metabolism, is responsible for helping people lose the kilos – it can burn a whopping 70 calories a day! Green tea also raises the level of antioxidants. It’s believed the antioxidant catechins in green tea boost metabolism and helps burn fat (can burn a whopping 70 calories a day!) Steeping time for the tea: two to three minutes at 85 Degrees Celsius.
While it is an active weight loss supplement, there is no scientific research that proves that it causes weight loss. In fact, the National Institute of Health does not recommend the long-term consumption of Senna tea. This is because long-term and high dosages can cause liver damage, heart function disorders, dehydration, abdominal pain, intestinal blockage, and diarrhea.
