Traditional bulking diets were once all the rage for putting on mass. You’re eating like a champ, lifting like a strongman, and becoming the biggest and best version of yourself. Bulking and cutting cycles go hand in hand with gym life like peanut butter goes with jelly.
You’ll see dozens of bodybuilders, athletes, and casual lifters following the bulking and cutting life to maximize their gains and get to their peak of shredded-ness.
While bulking—i.e. being in a major caloric surplus—can lead to some awesome mass and strength gains, when it comes time to cutting back and getting shredded, it can be challenging.
That’s because while a bulk will increase substrate for muscle growth, the mass amount of food you’re consuming can leave you looking like the Michelin Man, which means getting rid of the excess is going to take some work.
Cutting carbs and counting calories is one of the best ways to torch body fat and maintain muscle, but supplements can also play a significant role.
Whether you want to ignite your metabolic fire, ramp up anabolic processes for maximum muscle mass, or stimulate thermogenesis, a good cutting stack is crucial for anyone looking to maintain lean mass and melt away body fat.
So, we’re breaking down our top 3 cutting products. It’s an ultramodern stack designed to boost energy expenditure, trigger fat breakdown, maintain lean muscle mass, and ignite your internal fire.
In a hurry? Here's the ultimate cutting supplement stack for 2025:
What Is Bulking And Cutting?
Whether you’re an athlete or bodybuilder, cycling through stages of bulking and cutting is one of the most well-known techniques for gaining mass and size.
Essentially, it’s the science of bulking up to slim down, and it generally follows a three-phase protocol:
- Mass gain (bulking)
- Fat loss (cutting)
- Maintenance (strength)
Because each of these phases requires a different type of eating, the diet needs to be suited to match the goals.
For the bulking phase, we’re looking at a few key features:
- Caloric surplus
- Sufficient protein to maximize muscle protein synthesis
- Sufficient fat to optimize hormones
- High carbs to support high-volume training
The idea with a bulk is that the excess energy you’re consuming is being put towards gains. More food + heavy training = more muscle and more size.
For most people, weight gain inevitably happens with a caloric surplus, but when combined with heavy resistance training, that weight goes on as muscle rather than fat, although some level of fat accumulation is expected.
The cut, on the other hand, is a strategic reduction in calories to ignite fat burn without compromising muscle mass. In this stage, resistance training and sufficient protein intake are key to losing fat mass without losing muscle.
The thing with a cut, however, is that being in a caloric deficit isn’t the most ideal scenario for muscle gain and recovery, so you want to strive to do whatever possible to retain muscle while burning up fat stores. Diet is a great start, but supplements can provide an extra edge—we’ll talk more about that below.
For the cutting phase, we’re looking at:
- Calorie deficit
- Sufficient protein to maintain muscle mass (slightly higher than bulking phase)
- Higher fat intake compared with bulking phase (to avoid hormonal imbalances)
- Sufficient carbs to support high volume training
The 4 Best Ingredients For Shedding Fat And Maintaining Muscle
While not an inclusive list, before we give you our favorite products for torching body fat during a cut, we’re giving you a rundown of our favorite ingredients that increase thermogenesis, melt away body fat, and maintain lean muscle for the easiest, most effective cut you’ve done yet.
1. Caffeine
Caffeine is like the gold star for any athlete looking for a major energy boost. Its antagonistic effect on adenosine receptors prevents drowsiness and stimulates the central nervous system for a huge boost in energy and alertness.
Because adenosine receptors are heavily concentrated in areas of the brain responsible for things like arousal, vigilance, focus, and concentration, caffeine helps to support a more focused, driven state of mind for stronger training sessions 1.
But when you’re grinding down for the cut, alertness and drive are key for workouts, but it’s the thermogenic component of caffeine we’re looking at.
Studies show that caffeine may enhance non-exercise activity thermogenesis (NEAT) by elevating locomotor activity and may potentially enhance activity-related energy expenditure by activating thermogenic mechanisms that influence locomotor efficiency 2.
A 1989 study on the thermogenic effects of caffeine found promising results. A single dose of 100mg of caffeine increased the resting metabolic rate of both lean and post-obese individuals by 3-4% over 150 minutes 3.
While it may not seem like a massive amount, by simply adding a bit of caffeine to your supplement stack, you could boost your calorie burn by up to 150 calories.
2. HMB
For anyone looking to drop fat without compromising muscle mass, HMB is gold. We’re all familiar with leucine, the most anabolic of the amino acids, but HMB is a metabolite of leucine breakdown that exhibits some brilliant effects on fat loss.
When you’re in the midst of a cut, a caloric deficit can be detrimental to your muscle mass if you’re still training hard.
However, HMB can help mitigate the extent of muscle protein breakdown that occurs when in a caloric deficit or training in a fasted state and can work wonders during your cut. It does so in a couple of ways:
- Reduces muscle protein breakdown: High-intensity resistance training and endurance exercise may increase proteolysis (protein breakdown) in a fasted state, as the body resorts to muscle protein to fuel muscle activity. However, HMB can protect muscle tissue against breakdown and may also attenuate the fasting-related release of the stress hormone cortisol, which is a potent catabolic hormone that interferes with muscle growth and repair 4, 5.
- Promotes anabolic use of dietary protein: HMB works on a similar principle as many protein supplements that claim when you increase muscle mass, you decrease fat mass. One study found that compared to a standard protein diet, people following a high protein diet saw more significant weight loss 6. When combined with protein supplementation, HMB may boost muscle growth, promote an anabolic state, and increase fat free mass 7.
3. Forskolin
Forskolin isn’t a supplement we hear about often, but it’s super effective for burning fat. It’s an ancient herb that’s traditionally been a major part of Ayurvedic medicine and is well-known for its unique ability to boost cAMP (cyclic adenosine monophosphate) activity; cAMP is an intracellular messenger that triggers thermogenesis, testosterone activity, and synaptic plasticity 8, 9.
Forskolin, the primary bioactive component of the Coleus forskohlii plant, offers potent fat-burning, testosterone-boosting properties that can be a major advantage to any cut.
Studies show that because forskolin increases cyclic AMP production in adipocytes by activating adenylate cyclase, it directly activates lipolysis (fat breakdown) 10.
4. MCT Oil
The rise of coconut and MCT oil has changed the way we look at fat. Fat no longer makes us fat, and in fact, MCT oil may actually help us lose fat. That’s because compared to long-chain fatty acids like those found in avocado and olive oil, medium-chain fatty acids are metabolized differently.
They are absorbed directly from the gut and travel to the liver, where they are either burned for energy or used to produce ketones. Unlike LCFAs, they skip the digestive process along with the potential for storage.
So, for people training in a fasted state, MCT could be an awesome add-on to your morning routine to stimulate fat-burning and increase energy production. Studies show that MCTs can enhance fat oxidation and thermogenesis compared to LCTs in short-term feeding experiments 11.
One study found that subjects consuming MCT as part of their weight-loss diet lost, on average, 1.7kg more than subjects consuming olive oil as part of their weight-loss diet. What’s more, MCT oil may also increase the release of two key hormones involved in regulating hunger—peptide YY and leptin 12.
