Not directly — freeze-dried liver is calorie-dense (about 4 kcal per piece), not a low-calorie treat. But it can play a useful role in a weight management plan: as a high-value reward during exercise-based training, broken into very small pieces to stretch the calorie budget, or as a motivator that makes weight-loss-friendly exercise more engaging for an overweight dog.

Calorie reality check
A standard piece of Stewart freeze-dried beef liver is approximately 4 kcal. That sounds small, but for a 20-pound overweight dog on a 400-kcal-per-day weight loss plan, a 5% treat budget is only 20 kcal — about 5 whole pieces, or 25–30 broken bits. Any more than that, and the treats are eating into the caloric deficit you need for weight loss.
This does not make liver treats incompatible with weight management — it means they need to be accounted for precisely. Reduce the daily food ration by the treat calorie count, or count treats as part of the daily budget rather than adding them on top.
How to use treats during weight management
Pre-portion the day's treat allowance in the morning. Once the container is empty, no more treats that day. This makes the daily calorie budget concrete rather than abstract. Breaking pieces into small bits stretches the allowance — 5 whole pieces become 20–25 broken bits, all within the same calorie budget, which allows considerably more training repetitions.
Consider subtracting treat calories from the daily meal ration rather than tracking separately: if the dog's plan allows 400 kcal/day and you give 20 kcal in treats, measure out a 380 kcal meal. Some owners find this simpler than tracking two separate numbers.
Exercise training with overweight dogs
Overweight dogs are often less enthusiastic about exercise because movement is physically harder at excess weight and because some conditions associated with obesity (joint pain, reduced cardiorespiratory reserve) make exertion uncomfortable. High-value treats like freeze-dried liver are useful here: they can make exercise-based training and walking more engaging for a dog that might otherwise be reluctant to move.
Using liver treats to reward loose-leash walking, recall, and movement games turns exercise into a training session with rewards, which improves cooperation in dogs that are otherwise uninterested in activity. The training value of the treat supports the exercise that causes the weight loss — used as a lever rather than a comfort food.
Treat alternatives if calorie budget is very tight
For dogs on very restricted calorie plans, even broken liver bits may be too calorie-dense for the number of repetitions needed in training. Alternatives that are lower in calories per unit: raw carrot pieces (about 1 kcal per bite), cucumber slices, plain cooked green beans, or commercially produced very-low-calorie training treats (some are 1 kcal or less per piece). These are not as motivating as liver for most dogs, but they allow high-repetition training without significant calorie impact.
A practical approach: use liver for the first half of a training session (highest motivation, best learning) and switch to a lower-calorie treat for the second half once the dog is warmed up and engaged. This extends the session while managing total calorie use.
What weight loss actually requires
Canine weight loss requires a consistent caloric deficit — feeding less than the dog burns, reliably, over weeks to months. Treats derail weight loss plans when they are added on top of regular food without reducing the food ration, when portion discipline is applied to meals but not treats, or when the dog's begging behavior causes treat amounts to escalate beyond the budget. Liver treats are no different from any other food in this regard: the calories count, and accounting for them precisely is the only thing that makes the plan work.
